Ok taking on one variable at a time before I do anything drastic. Run new map Then evaluate Increase thermostat from 160 to 180 Then evaluate This while doing a ton of medical tests. So be patient.

So you added a richer idle via the two idle mix screws? Any idea what the AF is at idle? Mine seems to make my eyes water when if fires up like it’s plenty rich however I am starting to winder if it in fact needs to be more fat as it no longer fires up on the first crank ever and it did with...

Thank you for taking the time to write this out. Also for the link. I do have a slow ramp purposely to avoid detonating. I don’t want to hit it hard under load but ease into timing. The main issues I have is that this engine was set up for racing. High static compression around 205...

Other than some sort of knock sensor does a dyno have any way of detecting detonation? Or do you just have to check the plugs after a full pull?

Does the car ever hit those high timing points ie high vac/higher rpm? Tip in is where I need to watch for detonation according to the comments here above. I will be looking at tip in next but detonation is hard to hear a light tip in. I also.need to install my O2 sensor.

This is most useful. I haven’t seen anyone’s actual MAP before. Thanks man! Yeah there is mush to be said regarding real time tuning that this thing can do….I mike your hi timing at cruise! That will help with mpg and clean plugs. I haven’t seen anyone’s reverse idle as I add timing when in gear...

Ok I smoothed it out and lowered the timing. What do you think about this? I am not trying to emulate a mechanical distributor. I was doing some of this tuning real time while driving trying to improve the engine idle and transitions. This is why there was an abrupt change as it wanted more...

Thanks great inputs. I suppose I should not have drastic changes in the chart. When I watch the timing in real time it behaves smoothly. But I can certainly reduce the timing and hopefully kill any detonation and go from there.

I would think it’s a linear interpolation. But not sure. No smoothing that I have any control of.

Ok here is my timing MAP. This is Kpa vs RPM. Many places are never hit due to vacuum deficiency. The high advance at idle helps to compensate for in and out of gear differences. With this idle setting there is very little like 100 RPM in and out of gear. Top rows are WOT ie low vacuum. This...

Thanks for helping me on this! I will post the map shortly.

Yes I was just looking at Lightning Racing Carbs set. That’s mighty nice of you! Thank you. I will PM you when I receive boosters and banjos.

I live in AZ it will be 120°F soon lol oh and that tool is almost as much as a carb! I doubt I would use it more than once…

It’s the Chinese Air Gap don’t know what a cold air manifold actually is.
