Did you use IAC for idle correction?

Yes, I use IAC in conjunction with timing. I found that timing is faster than what the IAC can react. In gear I would stall often until I redid my idle timing tables.

Would be awsome to get base tables for ignition and fuel, but at this point i have a long way to tuning 🙂. My ecu does not have the driver for gm style 4pin stepper motor, so i am going to use the bosch 2pin fir 19mm hose.

36-1 Trigger wheel is ready for some paint.
Trying to find cost effective Bbc bracket for crank sensor, cherry Hall sensor.

I Didn't do much with my fuel at idle. I believe I'm around 13.5 AFR target. When warm my IAC runs at about 0-2%. The key is adjust the throttle blades so it does not need to use IAC at idle. (calibrate TPS after adjusting blades) I have my timing at 36° from 0-1000 RPM (target idle 800 RPM) and I allow idle stabilization timing to throw +/-8° timing to catch the engine at in gear transition with the help of the IAC to open +98% if need to stabilize the idle. I also have the IAC set to fast react.

What you think about the valve stem clearances for N/A, closed cooling, is 0.0017" int, 0.002" exh ok?

Look what just appeared in my Youtube suggestions...

Interesting, i quess the results would be different with marine exhaust manifolds vs those good flowing headers. I would never add 16 degrees duratiton to gain 10hp, when reversion and valvetrain stability is a concern. I think that the marine manifolds benefits more from the larger duration split.

thats fine,good valve seals will control the oil

I would bet different engine combinations would react differently, but it was a good video.
