Okay I have a LS/VTEC thats balanced and blue printed and bored out to 1.9L (oversized B16 pistons) and a fully built B16 head with gsr cams. Everything was converted to obd1. Its ran on a P28 ecu with crome. I was told that its just a b20 base map on the ecu & that the safc 2 was used to tune the fuel curve. I have no idea why the safc would be used to tune the fuel curve when it has crome. That doesn't make sense to me. The motor has about 2300 miles on it since the rebuild. Okay my problem is that it won't keep a steady idle. After it warms up its not so bad but still kinda bouncy. I want to get it to idle somewhat normal. Once she gets rolling though everything is fine its just at idle. Now she is starting to have problems starting up. She turned over but nothing. I let it sit after a couple of tries and then she starts but doesn't get enough fuel to idle so it cutts off. Is this because the cold start was disabled? Is this because of the tuning or does this sound like something different? I traded my GSRed EG for this and these are the problems im encountering with the car.
