I have been trying to tune my 94 Camaro all week. I got it running pretty strong but idle and low rpm it still runs rich. I have Tunercat and so far I have lowered the MAF calibration tables and I think its getting better but I'm afraid to reduce the MAF numbers much more. My BLM's do have a little split but seem to even out for the most part. The car has gm847 cam, 58mm tb, ported heads. Any advice would be greatly appreciated.

 

update I ran VEmaster and it seems to have straightend out my BLM's but it still idles too rich.

 

i dont know about tunercat, but in lt1 edit they have a 400-2000 VE table. Since it is running rich you will want to lower the numbers for the rpm's you want it leaner vs kpa you want it leaner at. I have a wideband o2 LM-1 and setup the MAP to find the kpa load it was idling at mine was 30-50 kpa, but it isnt a big cam either.

kpa 90-100 if 1 bar MAP is WOT.
