Anyone know of a company that reprograms the accord ecu?


I do not need any fuel/timing curve changes, just rev limit and speed governer removed. (for some reason the ecu got PMS when i installed the H23a1 tranny, i hit the speed govern at like 100mph, dumb DX)

 

i would like to find someone with enough clue to kill the EGR and other smog systems. not trying to hijack your thread, but i'd like the same as you in addition to those services.

it can be done on every other car in the world people care about... i wish i had a rom reader and skillz

 

yu0 can hijack my thread whenever, i dont care. Its all good. I talked to Katman and he has never messed with accord ecus before...


i do not want to switch to an integra unit. but if i must.......myeeeaaahhhhh.....

 

It can be done... im studying Hardware engineering and have been dealing with microprocessors and flash roms...

In Computer terms... you guys ever tried to flash your BIOS and shafted it? and to get it fix you have to get it re-flash... (there are ways to do this without needing a reprogrammer...)

Anyway well the ECU on the Car follows the same thing...

After reading the PDF files on how Hondata works, if you check out Hondata ROM Editor... if i can get my hands on the full version it allows u to edit exisiting ROM files... (Theres a page at hondata where they compare the fuel timings with the stock and mugen ones)

So my theory is, if you get EEProm Programmer, we can dump the ROMS (could be spoon, the stock one, watever) use the hondata ROM Editor and write a new rom and reprogram the chip with it.... with rev limiter change and what ever...


Someone shoot me if im wrong but there is a good chance this is working...

Been looking at the ATMEL AT29C256 this chip would be the perfect chip to program with the new edited ROM file...

 

up, I too need to get rid of the governer, espicaly if Im gonna go ECHC racing

 

the key to editing rom's for ECU's is knowing what addresses (hex) of the rom do what... therein lies the challenge.

 

?

 

pardon me?

 

if this is directed to me, well I don't know what to say.

 

nick are you ok man? what's wrong?

 

whoa.

 

i think my father reprogrammed my ecu?. ill ask....

 

You asked it the wrong way.


Sorry about that post! LOL

I wasnt at my computer and a friend of mine thought it would be funny I guess.

check out this board. no need for you guys to start from scratch

 

that is an amazing webpage THANK YOU for posting it!!!

I just finished ordering the Maxim232 kit to start datalogging

WOW! that website is amazing!
does that make me sound like a geek?

 

Sweet Just the site im looking for....

gonna get my hands on some chips and use the EEPROM programmers at uni...

Make some P13 ECU with VTEC 5500 and 9000 Cutoff

 

i just want to suggest that if anyone here is an assembly coder etc to try and help that project along.. for the MOST part they seem to wanna help 'everyone' some of them are trying to profit though.. obviously.

 

I'm a programmer, but assembly makes my head hurt Sometimes I read the website with pure amazement. Unfortuneately, not much for OBD2 cars yet..

 

i have been reading on that site, but i dont really understand any of it.

where can one get a programmer and some software?

 

why?

 

Last time I checked with Hondata, they had no intentions of decoding the F-series ECUs. They probably don't feel sales would cover R&D costs, since it's pretty easy to just get another ECU from a similar Honda motor that's already be decoded. I dunno about the legality of this in some race series/classes.

 

Yeah, I think the P28 (Civic SOHC VTEC single runner intake) is a better match for an F-series motor.
