Thanks.
Most definitely yes. I'm running an LM-1 on my 81 CIS Lambda engine. With the programmable outputs of the LM-1 it's now running closed loop at WOT at 12.8 AFR. I described that trick in another post a while ago. Mine also pinged in hot weather. Turned out it was running a touch lean (13.4) at the max torque point. Running it in closed loop now makes it run a lot smoother and it feels more responsive. Butt dyno says it makes more power throughout the rev band.
