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.

"Hmm. Ask him if he's the dragon reborn." "What?" "Just do it." ".......He said yes." "Tell him you are not darklings. He should open up." ".......Sweet. Thanks." "No problem." |

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. -------------------- "It's ok to be naked girl... I'm an artist!"

Actually you can flash ROMs but it depends on whether its EEPROM or PROM, I wasnt sure if the semiconductor in the stock ecu is EEPROM or not hence the question. -------------------- 98% completion --- aaRon |
