Ok So history on the car. Old setup on the car was a 2 BAR OS and a set of 127# FIC injectors running on E85. Set up was together and running for 2 years with no issues. I was over 90% injector duty Cycle and maxing out my 2 BAR map so after making some changes to the car over the winter to the intercooler and turbo kit (same motor and Turbo) I switched to a set of FIC 2000 injectors and went to a 3 BAR map from DSX tuning.

Now. I can only get the car to idle at 10.5:1 on the gas scale. It is also pig rich on light throttle cruising. If I load the motor I can get good O2 readings.

I have gone through all the injector data. I don't see anything I missed. I have lowered my Base fuel pressure. I have replaced my wide band O2 sensor. I have tried a friends wideband O2. I have moved placement in the exhaust.

I have even leaned the VE table out to the point of the car running funny but to no avail with getting the O2 to read leaner at idle.

In my logs it shows injector duty cycle is around 1-2% and min pulse is 1.9ms

Nothing was changed on the engine this winter other than the MAP and the Injectors.

I am really at a lose with this now. Any help would be great

Engine / Fuel / Transient / Min Fuel Milligrams is currently stock. For those size injectors try cutting that value to something like .010 see what happens.
