A person with no experience with the Tundra's ECU will actually believe that it works. Believe it or not, the stock ECU is the best option after a standalone for this truck. For crying out loud, it can add up to ~45 HP/TQ with simple bolt-ons and can handle 2 more lbs of boost (if not even more) on a Supercharger.
Don't waste your time and money with this crap or the unichip. Unless your adding a huge amount of boost or changing the compression of the engine, then stick with the stock ECU or go full standalone. Just my 0.02...
I'm down to dyno it and record a/f ratios. Should we start a donation pot?
I can say this, my a/f ratio at idle, light cruise, and aggressive acceleration but not floored is pretty much 14.7/1, nearly perfect. Full throttle starts out at 11.6/1 normally and will go as lean as 12.1/1 which is only slightly rich being that 12.5/1 is considered perfect for a naturally aspirated performance motor.
I'd have to agree with BRX, there is no real need to tune the Toyota ecu, it knows what to do and will work around anything that you can possible do, and throw it in your face while its at it.
