Hello, I drive a 2000 Camaro that just had the engine swapped to a LQ4 because a bad tune cause my LS1 to die. I got a different tuner to tune this engine but I still don't really feel right about it and was hoping some of you could possibly look at it. So, mods list.
LQ4 stock bottom end, 243 non ported heads with dual valve springs and trunion upgrade, longtube headers and ory + catback, 42lb injectors, fast 92mm intake manifold/throttle body & slp lid. Also cammed but I do not have specs at the moment, I will get them in the morning and update this post as soon as I can.
Attached is my config file, my tune, and a few runs. I do not have the HPtuners version that you can hook up the AFR to unfortunately, but what i have noticed is every now and then my AFR (ngk) will top out at 16.00 when I'm sitting at a red light and slowly go back down in the 14s which kind of worries me. Also from a cold start the car is almost completely non drivable, it will idle in the 11-12's range on the AFR for a few minutes then raise to the normal range of 14.5ish. My tuner said that is because the springs are really stiff and need to heat up but idk if I really buy that. Anyways, please have a look and tell me what you think!
