hello,i'm curiouse about the trd 160 degree thermostat .i solo race my 1jz-gte supra i have upgraded the radiator to a koyo racing unit.is there any one in here that runs a 1jz-gte with a 160 degree thermostat and the stock ecu?i here that for some cars you have to alter the ecu to compensate for warm up programming.i hope thats not the case here.i run in hot weather ,above 100 degree track temps sometimes.i need to know if the ecu needs to be altered to run the lower temperature thermostat.thanks for your time and patience.

well... that's a little cool.. but if your outside temperature is fairly hot... i can't see a problem with it...

it should be above the cold start temp so your idle shouldnt remain high...

just try it lol

thats what i thought,nothin to it but to bo it,stand back and let me do what's got to be did!thanks alot!
