ECUs
 

Anyone out there that knows about performance engine control units (ECUs)for the IS300? recommendations, realibility, installation, etc? thanks, shot

Are you looking for an engine management system (ems) or an actual race tuned ecu?
I'm not expert but I think getting an ems might be cheaper even though that's not even cheap it's like $1000 at least.
With a race tuned ecu, I highly doubt your car would pass inspections making it non-street legal, especially in ca...

Tubby the mechanic from Stillen was the 1 that said performance ecu's (street version) computer chips can increase the hp. here's a website I found surfing www.performancechipsdirect.com. $69 thoughts?

Just browsed the website and they say it wont hurt your engine or void your warranty and blah blah blah...but in the additional info (above) they say the opposite...IMO, if i wanted the power gain i would SC or TC. I think its some sort of resistor for the MAF sensor that will TRY to trick your ECU into changing the A/F ratio

Oh it's not an actual ecu, it's some kinda piggyback I guess.
I don't even think you could get a used stock ecu for that cheap
:)

you cant chip the IS ECU. :v8acura: dont waste your money.

Turbo your motor is you want performance.
