I have been trying to get my conversion done in time for Okteenerfest. I have run up against a brick wall and just cant seem to figure out what i am doing wrong.
If anyone can help me by looking at my tune files or providing insight it will be very much appreciated. I can get th car to idle but nothing beyond that. Any use of the throttle is less than impressive and almost useless. Meaning it bogs down and does not accelerate at all. I have no clue what i am missing. 2056 with new low impeadance injectors. Bosch Wideband O2 sensor. Really need some suggestions. Not sure if i can post the tune files here. But will try. |

Your post is contradictory. In one line you are changing timing to help CHT. In the next section you are fuel-only and not controlling timing.
If you are running timing through the distributor then changes to the timing curve will not make any difference to your tune. They are just parameters that go nowhere and have no function. If you want to run with a more lean AFR (lean burn) you generally have to advance the timing to match. This is usually done on low throttle cruise bins. However, if you are not controlling timing then you are at the mercy of the timing generated by your dizzy curve. Glad that the car is running well. Continue to tune. During the trip you can change the target AFR, adjust the fuel trim and find the balance of power, fuel mileage and CHT. |

I definitely could be wrong but I understood that the when using the tooth wheel set up you can select use table for timing. I don't know if this table impacts the firing of the injectors. I think it would not be related as you suggest but just wanted to confirm I was not missing something. |
