hey everyone...id like to ask if anyone knows what is a good ecu for the lexus sc430 ... i have an 03 SC430 and so far i have put OBX Headers..Injen Intake..performance catalytic converter...full catback exhaust..i know need to purchase a performance ecu and don't know which one or wheere to get it...please someone help me out..thanks!

 

I believe lexus ecu's are pretty much locked down. Only thing you could do is a piggyback like apexi neo or safc2, which you would have to get tuned. I heard it's good for 15-20whp though!

 

hey man..what do u think about this??

I think someone in Poland is get rich from a scam product.it is a universal item for both gas and diesel. The only two reasons they ask for specific car information is to make you feel like it's car specific, and to make sure your car has obd2. These products don't work like they say. Really $200 will get you 20 to 50 horsepower. Why would any one spend $800 for headers and exhaust for 12 to 15 horsepower. For my BMW with the n52 engine $400 for Ecu tune. You get 12 to 15 horsepower. If you add exhaust, 3 stage intake, and cold air intake you can get 30 to 40 horsepower. Do not be fooled!

 

well what can u recommend for me to put on next for my car...whats a third stage intake?..i have headers..intake..catbackexhaust..performance cat converter...someone told me to get performance ecu next but i can't find which one to get and don't have any idea...can u help me out please

 

A 3stage intake wasn't made for the sc430. It's a intake manifold that the runner length is lengthened or shortened by flappers. The short simple answer anyway. I honestly don't know what good kind of Ecu tune is available for the sc430. Did you look into what mistagill suggested? Just remember if it sounds to good to be true it is. A tune on a naturally aspirated engine isn't going to get you more than about 15 horsepower. It also needs to be vehicle specific. Most of what I know about Ecu tunes is related to BMW's. I do know the amount of r&d that goes into a tune. It costs more tha $20-200 per tuning to cover the cost back. Any proper tune for BMW they give very narrow range for gains. The show that specific vehicles dyno sheet. Sorry I can't give more help
