So, after reading the 'what we know about tC fuel management' thread, and bumming around on the mr2owners forum, I get the impression that nobody has been able to crack a Toyota ECU to date and get in there like the whole crew of aftermarket companies have with Honda ECU's (Hondata, etc etc).

I'm curious if this is because of a lack in interest by aftermarket companies in Toyota if if Toyota ECU's are just just insanely difficult, nye impossible? If this is the case, are there really any possabilities to truely get into our engines and fine tweak them to max potential, or are we doomd to wrestling with our ECU's and trying to monkey with the A/F ratio and thats about all she wrote?

 

 

Indeed....

 

With a will there's a way.

 

I figure, hey, if these kids today can crack high-end computer software, a car ECU should be like a snap, right?

 

Yup!
I've heard custom built ECUs from back in the days.. I'm sure its possible, just the R&D factor..

 

well, since I know absolutely nothing about this kinda stuff, how does one go about finding someone to do a custom ECU? I mean, its not like Fred's ECU-hijacking Service is something you find in the yellowpages

Do we approach someone like a ZPI/Dezod or whoever and say hey, get cracking? Are they already working on this angle? Do we hassle a traditionally Honda-oriented aftermarket company with our desire?

 

I dun think anyone has cracked it yet. Its going to be another RX8 issue

 

fraid i dun know the RX8 issue, they are having problems I assume?

 

Yeah, could you imagine the possibilities if we can actually work the ECU to it's potential like Honda.

From all aspects of fuel and engine management to electronic shifting for the automatic guys.

 

I think the rx8 has been out for 3/4 years now and in aug of 05 they just cracked the ecu. took em 3-4 years to crack it and make it stable when ever someon did do it the ecu was so advanced it would resort back to its stock programmaings it was horrible.

 

.....yikes.

 

i am gonna try some voodoo on my ECU

 

Trust me, with all the supra and mr2 owners out there modding their cars, the interest has been there for years.

 

and as such, no one has cracked it yet.

Does that tell you anything? ECU codes are one of Toyota's dearest secrets. It's like Coke's Cola formula only held tighter.

 

crack the toyota ECU??

crack it like wat?i mean... how hard is it for an aftermarket company to contact toyota and get info on the toyota ECU's for R&D on the aftermarket one...???

but then again... i dunno wat problems you guys are talking about

 

It's plenty hard. Toyota has never released (well at least for the past decade) the ECU codes. The only solution thus far has been bandaid solutions dealing with piggy backs or complete stand-alone ECU swaps. Only TRD has ever made a reflash for any Toyco ECU.
