My O2 sensor went kaput. So im trying to get my 99 running well enought to take it up to the shop to work on it.

My question is, does anyone have a stock fuel map they could plug 550 injectors into?

Ive been trying at it all day and cannot seem to get the fuel good enough to where when I press the gas pedal it doesn't stall

Thanks for your time.

Use the base fuel map for a '99 and just change the "required fuel" under "engine constants" by plugging in the flow of your injectors. You should also set the "injector dead time" under the "Injector Characteristics".

If your are replacing smaller injectors with 550's you will need to considerably change you VE table. E.g. idle area for 265cc was low 30's with 550's is mid 70's. Mine started first go with new req fuel and deadtime settings but then when it switches to the VE table it ran from 13 to 18 AFR in about 2-3 secs. ! Once you get it idling steady change up all the Values on the VE table by a similar ratio. Set autotune to easy, drive it very gently (without boost) and let autotune do its work. When its done a lot of changes and after 30 mins driving, fine tune it by setting autotune to normal, drive for 30 mins and then set to hard.
