Definately a scam. I've never seen anyone be able to reprogram the Toyota Multiplex ECU's and if so it'd be super mega expensive. Try getting an S-AFC and some dyno tuning instead. This is especially important with an intake (see my other post).

Sure you could reprogram it. It's called a "stand alone" ECU!! lol!!

The S-AFC won't s\retain your setting becuase of the ECU's "learn" feature. You would require something that would onvolve a "closed loop" system, aka stand alone.

The closest you could get would be the SRT intake setup w/ ecu incldued. The only drawbacks maybe t hat depending on your future mods, you may not be able to take full advantage since the ECU's are tuned for a specific setup. Now, on the other hand, I have personally reprogrammed SRT ECU's for people in the past, depending on if I had a program that contained similar mods for customers.

Take that info & go into the world & prosper my man!!!!!

Chow!

Actually this is half correct. The high throttle settings do not change, the part throttle ones if not done properly will affect the high throtle ones. YOu have to find a good tuner that looks at ECU fuel trim numbers and not just a wideband. We always tune S-AFC and E-Manage units and they work very very well. THe E-MAnage with a boost sensor is what we use for turbo apps and the S-AFC for milder NA setups. IT works very well. The SRT ECU works on the same premise as an S-AFC or E-Manage which is to say it alters the MAF voltage to tune fuel.

Thanks
