Does anyone in this board use the Apex'i ITC to adjust timing? I have it hooked up in my car but I don't have the slightest idea on how to use it. Personally, I would like to advance my timing a little bit more aggresive than what the ECU has. I believe my ECU is very conservative, my Techtom only displays 15-18 advanced at 15psi on alcohol injection. I see others consistently getting over 20 advanced on 18 psi with the same setup.

If the ECU reads knock, will it override the ITC settings?

Is there such thing as an "open loop" mode for timing where I shouldn't modify under a certain RPM so the ECU won't compensate?

What should I listen or look for when adjusting timing? EGT, pinging?

a few years back Omar installed a ITC but this unit really did not work on the supra, was the ecu would override the settings soon after this unit was not made anymore from apexi i think it was 2-3 years ago.

i think the e-manage works better for timing
