Hello, I am picking up a LEM4 setup for a decent price and have some questions. How old is the LEM4? I will be running this on a 2.5L Naturally aspirated motor, will this ECU provide me with a decent amount of control over the motor. I know it will not have all the vast functions of the G3 setup but I have tried the expensive hydra and it really did not do much for the price. My application is 13:1 compression ratio, cams, mild headwork, free flowing exhaust. About how much would it cost to upgrade this ecu? And is this a wire in only or is there a wiring harness that can be bought that will plug and play with my application. Thanks alot
Josh
