OFFICIAL FAQ: AEM J-Series PnP EMS

[DelSolid]

This thread is where we will answer all questions and post new information for the new AEM plug & play EMS for the J-series engine.

AEM P/N: 30-6051

Cost: $1,277 (Jobber)

Availability: It should start shipping to customers in the few couple of weeks. Definitely should get the first batch of them out by the end of this month (July 2010). The first batch will be small, only about 10 or so. The next batch will probably be about the same and follow in another month or so.

Where can I buy one: Please contact a sponsor of this forum or your preferred tuner and see if they are going to carry it. AEM strongly recommends that you have a competent tuner install and tune it for you.

What is it: The 30-6051 PnP EMS replaces the factory ECU and plugs in directly to the vehicle/engine harness. You connect to the EMS via USB and fully program every part of the calibration. There are over 1700 options, 100 2-D tables and 15 3-D maps available for tuning. There are almost 700 different engine parameters you can view or log. All required software and interface cables are included and all features are unlocked. A base map is included to get you started but the final tune is up to you.

What harnesses can I use:
1999-02 Accord V6 J30A1
1999-03 3.2TL/CL J32A1
2002-03 3.2TL/CL TypeS J32A2
2002-04 Odessey 3.5L J35A4
Both A/T or M/T harness from the above vehicles can be used. The A/T variants of the above harnesses have an extra connector that is not used with the AEM and you can simply remove or ignore it. As we identify more harnesses that will work we will add them to the list.

What engines does it support:
1999-02 Honda Accord J30A1
1999-03 3.2TL/CL J32A1/J30A
2002-03 3.2TL/CL Type S J32A2
2002-04 Honda Odyssey 3.5L J35A4
It will support many more engines than this as the cam and crank trigger patterns are programmable and the type of sensor used (hall vs mag) is jumper selectable within the EMS. But for starters we have checked those engines listed above as being compatible with the initially supplied base map.

What specifically can it do?
* The EMS will drive all 6 fuel injectors sequentially and you add up to 6 additional injectors (sequentially as well) for a staged injection setup.
* It will drive the 6 coils individually, not batch fire.
* It will drive your tachometer correctly without an extra module required
* It will also drive your speedometer allowing correction for different tire sizes, no extra hardware required
* It features a high speed 1MB internal data logger that can log multiple channels up to 250 times a second.
* Allows unlimited PC datalogging whenever you are connected to the EMS with a laptop.
* Full frequency based knock control with individual cylinder knock logging.
* Individual cylinder trims for fuel and spark.
* Internal boost controller (requires 30-2400 solenoid) gives fully programmable boost control and targets.
* Built in 2-step launch control and shift w/O lift.
* Programmable VTEC control. Set RPM, TPS, LOAD and fuel spark based on VTEC.
* 12 user programmable outputs for shift light, fuel pump, cooling fan, etc... control
* Rate of acceleration & Gear based traction control
* Password protected calibrations
* Datastream out to AIM or racepack dash displays or loggers
* Immobilizer is deactivated

We will post more details in the coming days.

Thanks for the suport! I hope to own one of these by the end of my build.

im curious how it works for both auto and manual harnesses? the ecu plugs are completely different from each other and are wired completely different from each other plus the extra plug you have to have via jumper harness from the stock car harness which is made differently depending on whether you use an auto or manual enginge harness. so how is it that both harnesses can plug into it and work if there is nothing similar between the two?

Which specific year/make are you referring to?

[acidbath124]

i have used a cl base model harness not sure what year with an auto ecu from an odyssey i think and then i changed out the sensor and other necessary pieces to make the 03 cl manual harness and ecu work and that is what i am using now

i know that the cl manual harness is completely different than the auto harness because i have used both on my car so im assuming others are aswell. so what i dont understand is how you could plug either harness into the unit giving that the ecu plugs between the two harnesses are completely different from each other and even if you could plug either in they are wired completely differently according to the cl shop manual from acura. giving that i dont see how it is possible to just simply take the unit and plug it into either setup as oposed to only being good for one or the other.or does it come with some kind of jumper harness depending on which setup you are using? im not trying to be difficult just trying to explain what i am refering to. basically what i am asking is how you can use so many different harnesses if the plugs are different? have you guys actually tried the unit on a car with the auto engine harness and one with a manual engine harness?

You are correct, this car does have a different ECU pinout for the manual CL. We will make a note of this in our documentation. Unfortunately we don't currently have a plug-and-play for the manual CL 2001-2003 with the different ECU. The ECU will still work for the harness from the automatic CL from 1999-2003 (2000 does not exist).

[acidbath124]

so what you are saying is that if you are using the automatic engine harness then the aem unit is usable but if you use the manual engine harness then the aem unit is not compatible?

[SLV]

For the 2001-2003 CL and CL Type S yes the 30-6051 will work with an automatic harness, but not a manual harness. Our website should be updated later today or tomorrow.

[TLdream]

why dont you just switch to the auto harness?

[wolydotmatrix]

why dont you just switch to the auto harness?

I have had mine running for a year with absolutely no issues at all what so ever.
"If it ain't broke".............

Cant really justify the purchase of a stadalone, auto harness, adapt the harness for manual engine, etc.....

I will just wait and see what comes my way. Still have a 3.5 to build, might use all the auto sensors/harness on the new build, which would remove the flywheel crank sensor.

[RPM SYSTEMS]

so the jest of is , to use the AEM computer you have to use a Automatic engine with a manual tranny . if you are running a 99-01 harness you have to add some wires for the vss sensors , due the 99 -01 are mag pick -ups and 02-03 are hal pick-ups .

so this wil be good for the auto/manual 2 gen design?

That seems correct because the main vehicle speed is configured as a Hall sensor and the spare speed is configured as a mag sensor within the EMS, so a simple repin would be necessary.

I'm not sure I understand the second question.

I can now confirm that the speedometer will work correctly without any extra modules with the original Civic dash.

[paton]

I am reading all this correctly? The AEM stand alone won't work for the most popular J swap? (J32A2 6MT) True bummer!

[TLdream]

I am reading all this correctly? The AEM stand alone won't work for the most popular J swap? (J32A2 6MT) True bummer!

It may be the most popular right now, because it was the easiest to make run correctly. With the release of this ems, it will be much easier to make the rest of the j series engines run "correctly" I have been doing some research for my build, and it looks like its only going to take rewiring 1 or 2 sensors in order to get it to run the 04-08 tl and tl-s motors.. So in the long run the auto motors/harness are going to be much easier to get, and they are cheaper.

[SLV]

I am reading all this correctly? The AEM stand alone won't work for the most popular J swap? (J32A2 6MT) True bummer!

It will work with the TL J32A2 6 speed, just not the CL J32A2 since the CL 6-speed has a different ECU.

[acidbath124]

i would think the harness would be differnt aswell would it not? also does the aem unit support drive by wire engines?

[SLV]

For some reason, the TL and CL are different where the manual and A/T ECUs are concerned. According to the resources we have available, the TL uses the same ECU for both manual and automatic vehicles.

The 6051 box does not support drive-by-wire because none of the cars it comes equipped on do not have it. If we make a PnP kit for later models that have drive-by-wire, then it will be supported.

what resources are you going by? from what i have found on an acura parts site the part numbers are different between the two so im assuming that would mean that the auto and manual ecus are in fact different from each other in the TL which makes perfect sense. i believe the only TLs that are manual are drive by wire which isnt as much a wiring issue as a component issue on the motors between drive by wire and normal that has something to do with the way it is ran if im not mistaken.also there is no manual TL before 2004

We use a repairshop database which I would guess is not nearly as accurate as the factory site. This type of ECU connector was only used on the TL/CL up to 2003 so this box is not meant to fit the later harnesses nor DBW (as on the manual CL).

[RPM SYSTEMS]

so in turn , AEM took the S2000 ecu and add some stuff to it . the S2000 and the AUTO J engine share the same main pin header as well as the main circuit board. take a look in side a j ecu and a S2k ecu and you will see what i mean.

well that ecu , if the info is correct , will take care of 89% of the guys and gals out there running the setups. so when will we see a official release to the masses ? and are there going to be base maps for people to use for all the different engine combo out there? or you going to just have one quick base map just enough to start the car and then they will have to have the car tuned?

The S2000 is similar as you said, but we tried to make this one as PnP as possible for earlier J30s and J32s considering that the people who are going to use this EMS are starting with a swap to begin with so we based this box around the most common vehicles.

As of right now we have only one solid base map, but that will likely change in the future as we can get more test vehicles in here, but since a PnP EMS for a swapped Honda is a relatively new thing, it will take some time to put out more base calibrations. Another thing is that, as we mention in our disclaimer (and I tend to agree with it), no matter how similar the vehicle you are tuning is, retuning will still be required.

[crxv6hn]

Hi!!! I working I try to make a V6 swap into the 1990 Honda CRX and I live in Honduras so I want to know if I purchase this ecu I don't need to remove the inmobilizer of the ecu and I can use the oem key of the CRX also I want to know if this ecu work with wiring harness converted to the ecu...

There is no immobilizer in this ecu. You can keep your factory key and it will work fine.

[Schweppes Built]

My big question to AEM is why make a ecu for a automatic??? Cause everyone is doing auto swap? Or people with automatic setups are doing big things plz explain?

[LKSi]

It is for auto motors mated to manual transmissions.. the most common swap

[Mug]

So with this ecu you can use the auto motor/man trans and the stock harness or does the harness still need modified?

[divinemotorsports]

Installed mine today, and going to tune tomorrow night or next weekend... Works great, but does need some tuning. 03 TL-S Auto Engine, and 06 TL-S 6speed LSD tranny. Auto wiring harness. Serial Number #009... :-)

[SLV]

I have created a forum area for the V6 swap EMS in our discussion forum here:

http://forum.aempower.com/forum/index.php/board,108.0.html

The calibration we developed for our test car is in there as well.

[RPM SYSTEMS]

you guy at AEM setup a base map for a j30a1 ! when most people that are running this swap are running a j32a2 or j35a4. i dont know if you tried the base map on other vehicles other than the one you tune for , but it dont work so well or keep the car running if you have a j32a2 engine that well . the fuel and timing table had to be reworked completely.

[hondaboy4life]

Will the calibration file be able to work at all on a different ems? I am going to be trying to run my j32 off of a 1060 box here soon...

That calibration was created on a J32A2. It is noted in the Calibration Notes.

Yes, the calibration file is usable in a different EMS. Just make sure that the outputs are configured to the right pins in the software.

[jswappedsedan]

what do u need to run a wideband so that the aem can read it...is it just the wideband or is there other pieces to buy thanks...just picked up my aem #14

[RPM SYSTEMS]

use the AEM 30-4100 wideband . there on ebay for around 170 - 190. very simple to hook up. 4 wires , red - 12v , black - gnd , white - 0 thur 5v out , blue - serial data output. well run the power and ground off the power that is being supplied to the ecu. connect white wire to the primary O2 input wire on the harness . then setup the AEM EMS setup with the pre-set for there wideband. now you are in business.

[hondaboy4life]

I would recommend getting the AEM wideband sensor and then getting AEM's serial data gauge. It allows up to 20 outputs or something like that.

[blink]

I am interested in using this EMS to do a j32a2 swap in my 94 EG Si. Looking through the posts I know you guys have made it work with the Eg, however the AEM website states that it is compatible with


* 1996-2000 Honda Civic EK chassis
* 2000-2001 Acura Integra
* 1998-2002 Honda Accord
* 1998-1999 Acura CL 2.3


and requires the 30-2982 extension harness.

My question is this, can the EMS (30-6051) and the extension harness(30-2982) be used with the EG without modifications and if modifications are required, what are they? Thanks

I installed the EMS on my obd1 dc2 with no modification or extension harness.

was super easy.

*edit*
I guess if you call splicing like 3 wires modification then that's different. I suppose if your looking for a straight plug and play option then that may be the case.
but as I recall it was simply plugging the ecu into the V6 harness and running a couple of power wires to get ignition stuff good, then a couple more for speedo and tach.

It will work with any vehicle that has a wiring harness from the cars listed on the website and the instruction manual. The 30-2982 extension harness is not required to install the 30-6051 as long as you have the same ECU connector and pinout. If you use the wiring harness from a 6-cylinder 2001 Honda Accord, you should only have to repin 1 wire: reverse lockout. The rest of the work will be routing the new wiring harness in the car and the power wires as mentioned.

[MoneyPit]

I received my box today, was startled to see in the instruction booklet that the OE narrowband O2 sensors are not compatible with this unit, and that they must be replaced with widebands in order for the unit to work properly? Doesn't make sense to me for closed loop fuel trims, especially if the base calibration setup is modeled after the stock ecu.

Say it ain't so.

Also, the '01 Cl Type-S AT engine harness is the same as the '02-'03, so you may want to update your compatible harness list.

[nutnut]

Say it ain't so.

It is

[MoneyPit]

Hmm...I assume you are running this unit? I know it has the capability to use a wideband for fuel trimming, but I didn't think it was required. I'd like some sort of confirmation that this is the case rather than an "it is," especially when this is direct from the AEM website:

AEM's Series 2 EMS is a complete engine control system that plugs into the factory harness and uses the factory sensors. This means you do not need to replace any parts of the harness or sensors, just plug the EMS into the harness and begin tuning!

The only reason I'm even concerned is because I already have an Innovate wideband and don't want to have to purchase the AEM just to get this standalone running. I'm wondering if the Innovate wideband controller will speak lambda with the EMS here...

[nutnut]

I'm not running it (yet), I just remeber it was in the installation instructions I read - http://www.aemelectronics.com/Images/Products/Installation%20Instructions%2030-6051.pdf

wideband sensors required
original O2 sensor not supported

It looks like it requires UEGO between the sensor and the EMS, the actual sensor could MAYBE be a generic wideband, I would ask AEM about that.

Edit:
Yes it reuires the UEGO: http://www.aemelectronics.com/inline-wideband-uego-controller-1159

AEM no longer sells EMS' with a built in UEGO, and we suggest this as the alternative to those looking to have a UEGO to go along with their EMS.

[slammedej1]

Whats the going rate for a tuner to tune a AEM standalone for one of these engines?

[crxv6hn]

anybody can help with a base tuner map because my car is stock conditions but i want tune up the rev limiter and other modifications in the software i really appreciate your help..

[Chibi]

i install the ems and my speedometer don't work at all...i put back my stock ecu again and speedometer works...so i have no idea what is going on...anyone having this problem?

[RPM SYSTEMS]

what happen is AEM went with tim's design for his harness. if you have a Tim harness it does not have working speed sensors . so aem thought that customs would buy tims setup and have people deal with the problems with tims setup.

i am i the case . i will try to have some kind of direction for the guys on the site that is using the AEM THING!

SLV,

I have a manual 03 CL type S swap (M/T harness, engine, transmission, and ecu) and just purchased a 30-6051 EMS.

I've already mapped all the pins from the Manual harness over to the Auto plugs except for the TDC and CKP sensors due to the fact that the EMS is setup for the mag pick-ups of the auto motor rather than the Hall sensors that the manual motor has.

In your original post, you stated that the 30-6051 could be setup for Hall sensors. Please elaborate on this subject. What needs to be changed within the EMS as well as the software? Or, should I start looking for an auto harness and TDC/CKP mag sensors ...

Thanks

i was playing with the idea making the aem on the manual . there is a circuit design i found that will convert the signal from a 5 v trigger to vr(sin wave) output . if you use that type of circuit design you can make it work .

AEM directly has said that the ecu will not work with the manual engine . mostly due to the plugs and the sensor pickup.
