Your input is welcome on Ksystemsengineering.com, my site- I've finally finished the piggyback ECU... I've seat-of-pants tested it throughout development on my stock Celica GT-S, but I am about to get the final dyno testing done and then I'll be starting to mass-produce and make them available in limited quantities... I expect to see 13-15hp, which is near the estimate I've heard from JET and other ECU re-programmers, so I assume I'm on the right track as far as sensor signal processing and ratio modification....

I plan on track-testing and showing the prototype (and dyno sheets) at OSW dragway next fri.... FL ppl- check it out.

Looks like its just another SAFC that alters the A/F signal. What makes it any different than just getting a Apexi SAFC and getting your car dynoed tuned? I assume they cost the same price anyways.
