amazing work! keep it up don!

[unheardmyth]

so in the future, once everything is worked out. are you making this "chipping" a DIY kit or more like jkpro, as to where we send the ECU to you for install and are provided with software? Or will this be comatible with Crome? very interesting and keep up the amazing work! :eek:

[hondaboy4life]

Can't wait!!

[unheardmyth]

What kind of tuning capabilities should we be able to expect? Similar to kpro, in terms of perameters and ease of use?ex: 2 step, antilag, delete inneccessary sensors, ie, O2, IACV. Ansl, scaling larger injectors? Just curious and very interested in the progress. Especially considering how new this swap is to most. Thanks for being a pioneer to lead the way to new developments.

[ep3moschini]

Will I be able to take advantage of this with my 01' TL? (boost/launch control/ ect)

[civicdrivr]

*subscribed*

If you can get it to support boost I will give you a hug. And a kiss.

Anything to keep me from running a damn piggy-back.

[e30cabrio]

Very cool! I look forward to your progress!

[Rajca]

im looking forward to this also.

[civicdrivr]

Jeez, its like an AZine orgy in this thread :p

[friesm2000]

Jeez, its like an AZine orgy in this thread :p

:snicker:


but yes this hacking would be a godsend for all the J's out there

[Rajca]

^welcome aboard. haha

any new updates?

[wolydotmatrix]

Don,
Any updates by chance?

[civicdrivr]

Innnnnnterestin.......

[Rajca]

still holding off on the aem fic to see if this works

[Singlecam_eg]

Now this modded version of CHROME is it actually a modded version or is it the same version available and your just tricking "X" to do "Y"? And will this be tunable in car or will it be like chrome/uberdata where u have to remove the chip and revise ur fuel map ect. Do you kno what model that ecu came from with the 2 MCU's? Will it still work with the chrome hack or are you still unsure at this point? K-pro compatability/features would be awesome by the way...to bad you couldn't marker it as J-PRO without hondata up ur ass

[wolydotmatrix]

Cool.

I assume by one of his previous posts that it will use a usb reflash system like k-pro...

slow ass:p :ninja:

[Rajca]

updates?

[CarNut4Eva]

J-flash-pro in progress?? Man this is awesome, so basically eventually you could tune on a laptop while on a dyno?

Ok lemme get this right OBD1 is 32k, stands to reason, there is less to read/adjust with OBD1 regarding fuel/timing/rev?

Now OBD 2 J-ECU is bumped up to 96k, is that due to the extra fuel/timing/rev map for the two extra cylinders of the J, and that OBD2 is a more complicated system?

Also, since you're bumping the J-ECU to 128k-flash memory would you be able to store some base maps with basic bolt ons as well as maps for diff. turbo/SC setups??

Please correct me if I'm wrong ... you know me I like to research a swap and its potentials before acctually doing it.

Don this is some pretty neat "stuff" you're digging into.

[civicdrivr]

hondoody can kiss my microchip. this is business nothing else.

:D

If you are able to make this available and have similar features as the K-pro, I will drive up to NY and give you a hug or kiss (your choice, no homo) :p

Plllleeeeeaaaase save me from buying an AEM EMS.

[civicdrivr]

Yea, I found out the AEM EMS doesnt support out crank sensor so thats off my list.

[Rajca]

damn it, fawk.:mad:

but the aem fi/c works right?

[JCharged]

Some real ground breaking stuff here. Props to you and I will definately be one of the first few to get this.

Ill be right there with you :cool:

Don, if you even want to do the install Ill drive up to NY.

[xero_xero]

can a kpro to control the functionality of this motor? you can program for 4, 6, or 8 cylinders.

just wondering, saw a jumper harness running dual ecus to maintain functionality (tcs, immo, cluster, ect) but tunability of a kpro( fuel map, vtec, aux outputs)

here is what i find.

interesting, very interesting

Isnt this their solution for running a K in the honda fit?

[Chibi]

i have the odyssey ecu that has the two chip in there, can i still use it to run the car?

[civicdrivr]

come a cross a small setback in the design , but still working on finding a to make it work.

Any luck yet?

[JCharged]

The anticipation is killing you huh?

I'm ready to send my unit. It's all out of the car now. :cool:

[civicdrivr]

Hell yea, I want to tune this damn thing.

And once Don gets it up and running Ill drive there and pick it up. Hell, if he wants to tune it thats cool with me.

[JCharged]

Let me know when you do, I will take the drive up there with you and do the same.

[DC3328]

:eek:

[civicdrivr]

Will do.

[spoolinspoon]

Will do.

Me 3 :)

[civicdrivr]

ROADTRIP!!! lol

Don, hows it looking?

[civicdrivr]

This just made my day!!

If I understand you correctly though, it can be reflashed, but you havent gotten Crome working on it yet?

[JCharged]

Damn it. Now I have to find myself a manual ECU and rewire again.:mad:

[spoolinspoon]

wow, thats great news!

come on advance timing :)

[marcucci]

Very interested in this for several potential swap applications. There isn't much out there for the J series, and this would offer a stock-ish solution. If you could just find a way to make AT PCM's act like MT ECUs, that would be worth it's weight in gold right there.

[jswappedsedan]

Theres a lot of us down here in florida waiting in anticipation....PLEASE HURRY

[LKSi]

How's this coming along? Any recent developments?

[InvaderTrax]

Any news?

[LKSi]

What is the story with OBD II compatibility? Will it be similar to the Kpro??

[r710]

Don, if you need more ecu's to tear apart, i have about 3 or 4 at work that im willing to donate to this cause.

[LKSi]

didn't think about the obd2 port to much , but i can make it have readings off the ecu for the PIOD for the DLC port to work properly. any part that dont cost you money that will help me , thanks.

Nice, I love the way KPro is set up so you can remove sensors and the immobilizer code. Maybe have the option for removed EGR, ELD, IAC readings.. etc on your unit?

[r710]

I found a few laying around the shop

[RPM SYSTEMS]

HOLEY SHIT! you think you got a few. WOW! t thought i was bad for having ECU . HAHA

[r710]

Haha, I have one with the single oki and the rest are dual processors. I also have an 05 ecu, it's a motorola unit. Let me know if u need any of them. How much are you going to charge to modify the ecu's?

[j32noober]

Same here, I may have a few ECU's around as well. If you need some let me know and i'll try to round some up to donate.

[gfrg88]

What you think price is going to be??? What all will it include?? Can't wait for this!!!! :woot:

[junior32a]

this guy is the best

[junior32a]

hey man whats up, im looking for ecu and you seem like u not to far from me, and i dont mind accepting donations...lol....

[crxv6hn]

what i need for make the ecu reflashed how to say with usb connector...i really appreciate your help..thanks

[crxv6hn]

ok for a while i have been working no hacking the J-type ECU and have made some progress
finding parts and info on the computers was not to easy. this is what a stock ecu looks like for the most part inside:

http://i733.photobucket.com/albums/ww337/danjerusmoke/DSC04137.jpg

what i plan to do is remove the MCU from the ecu and interface the unit with a adapter board
using a part like this :

http://i733.photobucket.com/albums/ww337/danjerusmoke/128adaptor.jpg

we will remover the MCU from the ecu and put the adapter in place of the MCU .

http://i733.photobucket.com/albums/ww337/danjerusmoke/idea.jpg

the OKIDATA chip set they use was built just for the Honda motors no other systems use this chip. so it was hard to find info or people to talk to about the chips. the chip number msm66589 is a 128 pin QFP micro controller that has the same properties as the earlier chip sets. there is a pin if enabled make the MCU look for code outside the chip. the code is 48k compared to the 32k in the obd1 ecu's . there is no place to put a chip on the board , so were making a adapter board to put a eeprom chip or flash memory for programming. OKIDATA was cheap when making there ecu because they did make a reflashable MCU . they didn't use it the production of the automotive ecu.

the software look simple enough . some of the base code can be read by the CROME tuning program . timing , fuel and rev can be changed , but that's it right now. still braking apart the rest of the code . found the code of the solenoids . dont know how to change them yet . we can use it for the solenoids for boost , meth , nos . still working on the adapter board. will give you update when i can .

forgot did find out some else out , there is a small 8 pin chip in the lower right next to this green upright board. the 8 pin chip is a serial 8 pin PIC chip, that holds 1k of data . could not figure out what it could be . so i unsolder the chip and read it in my programmer. on the chip was the VIN number and Mileage of the car. plus some other code but to small to be the code for the tuning . thought you would get a kick out of that. :)


don
rpm systems

i want to know where i can find this kind of chip.....and how to install the usb connector for plug and play with computer

[gfrg88]

Any updates on this???

[crxv6hn]

how much this work Don because i really interested because i making a j swap into a ef but i need to remove the inmobilizer and install this chip also how much the wiring harness for the ef..thanks

[friesm2000]

still nothing :mad:

[nutnut]

we have stopped work on hacking the stock ecu right know . we here have put our time on building a full standalone ecu. which has been easier that redesign a factory ecu. will will have something for you guys shortly . rome was not built in a day and i dont have a major R&D department to help me.

Will it replace the stock ECU completely or just the drivetrain management? Personaly I would prefer the later to retain some stock ECU functionality (like TCS that utilizes ABS sensors for example).

[friesm2000]

:nod:, same here want it to keep the functionality of the factory ecu

the only ones that will would be a type of piggy back would be , trip-tronics , and some DBW cars . other than that will be a full standalone . we are working on the stock DLC port to work on the cars as well for those guys that need the port to work .


especially when you have to pass emissions, and one thing that they do is plug into the DLC port

and personally i could less if it is hacking the factory ecu, or it is a specially design standalone ecu that keeps the functionality of the origional ecu

[unheardmyth]

just out of curiosity, what programming language are u creating the software in? and is any of it in ML or BASIC?

[3.SL06MT]

i put the project on hold for now . due to finishing the MEGA6 ecu for the group. the stock MCU has a pin that if you short it out to ground . it will look for a outside address for the software. the funny thing is the the same address header for the V6 ecu is the same as a obd1 ecu . address starts at #C8000 . the base code is 96k . compared to the 32k were used to. probably due to the DLC coding and transmission .

i have done a data dump of the MCU already. all the code is in Assembly. i have a program for C++ the will do some of the work to convert Assembly.

i made a adapter board that allows me to access the MCU . i removed the stock MCU and attached it to my board with 128k flash chip. then i have that connecting back to the mainboard in the ECU. were i am at now is to look the code while the ecu is running in a car. the way i set up the adapter board is i can watch the data be accessed . seeing what registries get accessed and then hope to be able to edit them or delete them without effecting the main base code too much. then i can write something in c++ to write the changes for the mass that want to use the stock ecu.

i hope by solving this then i can use the same data to attack the s2000 ecu. the s2000 ecu is like the little brother to J ecu . basically they both use the same main board and MCU.
Soo....you're telling me we can use the S2000 Hondata Flash? 8)

[3.SL06MT]

No. hondata flash-pro is for the 06 s2000 ecu . the earlier ecu 's like 02-early 05 had the same ecu.
Of course lol. I have the FIC anyway, only it's only seen the light of day maybe twice from it's box :mad:

[pitman]

so i guess this is the the only way to tune without a standalone.



and i cant read rpm systems posts for some reason
