My quest of running Ford GT500 EV14s

I doubt these will cure your hor restart lean condition. I still have the same issue with these installed, just like I had with factory 1.8 injectors and RX7 injectors. The change in dead time when the injectors get hot still messes with them. I am looking at adding some kind of fuel rail temperature measurement so that the MS can richen the hot restart idle untill the injectors and fuel return back to normal operating temps.
You might want to do some research on the hot idle issue. Lots op people seem to still struggle with it.

Where is your IAT sensor mounted? You may be dealing with a heatsoaked IAT on restart rather than heatsoaked injectors/fuel system. Moving mine from next to the throttle body to next to the air filter helped dramatically with restarts. If you are boosted, an even better location is post intercooler under the bumper or nose, completely outside the engine compartment.

It was always hot fuel/injectors, never the AIT.
I've not experienced hot restart with ID1k's. They were fine.
I am currently experiencing hot restart on the OEM NB2 injectors. Its not too bad though, on the current car/setup, and I know it's not AIT related.

Lars: Looks like Scotts old street tune. Quite lean (even with the 0.2 subtracted). Others will likely come in with 13.5 at 85 kPa and 12.5 at 100 kPa. From my research of previous MT AFR threads, I don't see consensus. I have run one that looks like Lars' and one (presently) that looks like the rich ones. Very little change in MPG or performance that I can tell based on NON-SCIENTIFIC "research".
Lars, why don't you just adjust the WB02 calibration in your MS and make them read the same?
