Hey guys, I've recently got my copy of ecmlink along with the ecu. I've read through all the instructions. I've set my 3" gm maf, my 580cc injectors. My original ecu I had before switching the car would idle high on first start up then as it warms up it would gradually come down and settle at 750. With the new ecu it idle high and keeps going up slowly then start surging. I've checked my isc values all the coil came back good. I connected the isc and turn the ignition on and it just "twitches". I connected my original ecu and did the same procedure and it moves in and out. I've checked the drivers and they look like brand new, even under the board looks good. I don't understand why it is twitching and not moving in and out with the ignition on.
