Where in the tune can you fix this type of cold start issue |
Idle air flow table is vs. coolant temp assuming your fueling is correct. |
Also look at the spark advance at idle. Depending on what you have to tune with. |
damn I paid frost to go over my tune was worth every penny! I had the same thing! |
OK, It was just tuned. Ive been going back and forth with the tuner working out street bugs, so Ill have it fixed, I was just curious what actually caused it. Inquisitive minds want to know! |
Cold start / afterstart enrichment can be excessive and so can the EQ (OLFA) table especially after a cam puts you at higher than stock idle MAP. You should be able to tell by comparing commanded EQ against these to see who's in charge. I had to skinny down all of them after my cam swap. But go to far and you may get harder starting. If the surge is still there after 10 seconds into cold start go for the EQ (vs ECT vs MAP) first. If it's only initial and goes away quick, probably the after-start enrichment. |
