Can't get my FD to start again
Hey guys,
I'm running into a problem trying to get my FD to start, over the winter i rebuild my motor and dropped it back in the car I also went from twins to a single. this past Thursday I fired up the car and had it running great during the time I was trying to dial in the A/F ratio but the car would not react to any changes I made in the fuel map (PFC with datalogit) So, I decided to initialize the PFC and now its been downhill ever since. I went through the initialization process but I could tell that the car was running weird while the A/F ratio was around 13 to 1 at idle the car felt like it was running lean once the initialization process was done and I stepped on the gas the car would completely lean out (17, 18, 19 to 1) even after making changes to the map it would still go lean when I stepped on the gas. I tried the initialization process 2 more times with no luck, I finally called it a day and went back it yesterday morning but the car doesn't want to start at all now and I have no clue what it could be now. So far I have tried the following
Fuel pump
Fuel lines
fuel pressure (38 psi)
injectors ( resistance at 14 omhs)
ignition coils ( resistance at 1 omhs)
spark plugs
spark plugs wires
motor compression (100psi)
Everything checks out for a running motor. any help would be greatly appreciated

Initializing the Power FC will wipe out all your specific settings and reset back to the original settings for everything including the timing maps, fuel basemap, MAP sensor settings, and fuel injector settings. You need to reload your own file for your specific car, hopefully saved somewhere. Otherwise, it will be a long and grueling time trying to rebuild every major table and all other car specific settings. If you simply used the original settings from the start, that would not be ideal but OK for a stock twin setup, but that changed with the new single turbo setup.

you just reseted the powerfc mate
you have to set it up from the start and that doesnt mean only the AFR maps.
you also have to state the correct injectors and map sensor and dosen other details
