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. |

I can see the logic of both approaches: focusing on the VE table first vs. the AFR table first.
If you're tuning the VE table, it seems to me, you should be open-loop. You then tune via whatever feedback you have available to you (WBO2, dyno, etc) to bring the VE table to 'perfection'. Then you can enable closed-loop, after populating the AFR table with the values you see while running your final tune. --OR-- If you're tuning via the AFR table, you run closed-loop from the start and then tune via whatever feedback you have available to you (WBO2, dyno, etc) to bring the AFR table to 'perfection'. Then populate the VE table with the values you see while running your final tune. But I feel like, from the other responses, that I might be missing something from the picture. James? Jeff? Can you correct or add to my understanding? |
