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. |

you mention the car idles. Does it idle smoothly? If so, I would expect that you are firing 4 cylinders.
Is your WBO2 reading in TunerStudio (or Megatune?) If so, what is the AFR reading? Did you setup TS to read the WBO2 correctly? If you PASS the first two steps above the next question is: Have you started to tune the car? Do you understand tuning the car - meaning recognizing Lean vs Rich? EFI is exactly the same as adjusting the mixture with a screwdriver or changing jets in a carb with the exception of using keystrokes and instantaneous feedback. If the car is lean, add more fuel. If its rich, take fuel away. TunerStudio will even do this for you if your target AFR table is good. The car will absolutely run like crap if you have not tuned the car. |

Ground wire came lose. Seems to be running on all cylinders. I think I do have the understanding on how to tune but I think I must have something incorrect because the efforts to tune do not produce the expected results. I think I had an issue with the MAP setting and the injector sizes. |
