anyone know how to flash the eeprom on a 89 supra?

i wanna flash it the same way a super chip does, only without the chip

 

unless you own all the equipmpent in a tuner shop, there's really no good way to flash your own ecu. you either need to pull your ecu out and send it off to a company to do the work (along with a list of your mods), or drive to a dyno shop and have them flash and re-tune.

 

thanks man.

 

Es ist nicht ein Problem, Freund.

if you've done any mods at all, i highly recommend going to a dyno shop (specializing in toyotas) and having them do a proper tune. much much better than the alternatives.
