It starts and runs great. As it warmed up it started to go lean and just cut out. So I let it cool all the way down and tried to tune the Warmup Enrichment. I increased the warmup enrichment as it warmed up. At 130 degrees it was at 112%... then at 160 degrees it has to be at 100%. The afr was then very erratic. Mostly lean. So then I tweaked the fuel.... it ended up being pretty rich and still erratic. I then decreased the afterstart enrichment. Maybe I should have jacked it up. But I was under the impression that once the car is warmed up to 160 degrees, the afterstart enrichment should be at 0. I have been able to drive the car decently until it warms up. Then the fuel is erratic. Here are some maps... help?
