Ok , so I have the engine running but it needs tuning. A little background, rebuilt stock 2.0 with D Jet, running a 123 dizzy. It fires right up and idles a little rough at first then smooths out. It revs fairly well and sounds good. The problem starts under load, it starts to stutter a bit.
I have not messed with the adjustment screw on the ECU or tried adjusting the throttle position sensor, or been able to check my fuel pressure. I’m hoping to rally any troops in the north Florida area to help me get these final details ironed out. Thanks in advance, John |

If I remember correctly, didn't the first 2.0s all use the 1.7 ecu and just add that cht resistor and bigger injectors.
Yeah, I dynoed mine some months ago, it seems to like 35-37 (all in, not at 3k, that is max advance). I should say that's what I get on my cheap timing light. It may not reflect reality. We set the timing at the Dyno by the numbers, after which I checked to see where it was on my timing light. Chris fowley (tangerine racing) might have some suggestions on the 037 vs 019 mps as well. |
