Default Upgraded to Fast 2.0 now the car won't run. Anyone have the same issue?

I just unplugged the Fast... sent it out... got it back...

She fires.. but wont idle.
I can pedal the snot out of her to keep her running... no matter how much throttle i give... it will lump around 350 rpm-750 rpm... but im seriously peddling it.

I went through the calibrations as best i could... but not really that savvy. I just assumed the car would be the same as it was before i sent the box out.. but thats not the case.

I changed nothing mechanically... and it ran perfect before the box ran out.

Am i missing somehting?

Can the injector vs battery thing actually keep the car from idling?? As it sits.. there is nothing changed but i had to re calibrate the throttle position.

Thanks.

Maybe you need to do a crank position sensor relearn? I really don't even know what a fast 2.0 is.
