Tweaked ECU Options

[thespacepanda]

I've got a question for you guys/gals. A mechanic friend of mine that owns his own shop said that one of his mechanics can tweak the ECU of any car to give it substantial horsepower/torque gains. He has an Integra with ~175 whp that is completely stock save the modified ECU.

He says he can probably get about 40-50 more power to the wheels with proper modification out of my 7A-FE. Any of you guys ever done this or know anyone that has?

Need to know before I pay him a couple hundred bucks for it.

not going to happen, period.

Cant you flash the ROM and reload it with new data?

ROM = Read Only Memory = NO new data. Like a CD-ROM... you cannot simply "reload" different data once data is finalized onto its memory.

And to the OP... these are basic 4 cylinder engines... no matter what your friend claims... the physics involved with these engines simply cannot make 40-50 more horsepower with ecu tuning alone. That's impossible given the stock engine. You also cannot compare this engine versus that engine because the engines are NOT the same in terms of making peak horsepower.

well.....there are many PCM's where you can flash the ROM's right from the scantool. GM, Mitsu, Chrysler, and im sure others allow this from their scantool, aftermarket handheld, or even a laptop with the correct software and cable. infact theres a place called openecu which has a big base of support for flashing pcm's. cali spec 3rd gens and evo's with a certain pcm that uses a certain cpu are big in the flashes now since you can load an evo rom to a 3g pcm, make a few minor changes, and run a boosted 3g with the stock pcm and no piggyback/standalone needed. it'll run like an evo as a matter of fact. heck you can even just edit the pcm values and for those cars pickup a bit of power from adjusting timing and fuel maps to suit what you've added or done.



sadly, this doesnt exist for the 6th gen celica.
