Also you have to remember that ideally you would want to own an FTC1 from www.URDUSA.com from Gadget and Brian's company Underdog Racing Developement.

Check. Got it in place. It's great that buying one from URD came with the FTC1 pre-programmed for a typical sea level 3rd gen 4Runner.

The ability to adjust timing is crucial for our application!!! Our timing is about 15 degrees advance around idle and somewhere around 24-30 or so when at full throttle and knock. THe knock sensors don't activate until 3000 RPM (peak torque) and will retard timing in moderation to avoid ping but when the situation gets extreme (ie. 14.7:1 in boost) it will not be able to adjust enough.

Great info. I need to review where my timing numbers are compared to your info. It's very possible I didn't adjust my timing enough. I got nervous if I had to make significant changes in the numbers.

Thanks for your help!

One other question -- when coasting downhill with zero throttle and a couple thousand rpms (such as with overdrive off), there's very little air and fuel going through the engine. Is it a concern that the wideband A/F meter displays "lean" then? Should I be trying to tune that out? I stuck with Gadget's original numbers in that area of the FTC's map.
