tuning AFR on an N/A ecotec
Tuesday, January 02, 2007 5:52 AM
I autocross an ecotec powered car it's not a Jbody but I hope y'all can help anyway. I have the usual bolt ons. Intake LSJ manifold and full 2.25 exhaust. My problem is I'm going really rich at WOT and I know from past experience with carbed race cars that lean is mean and rich is slow so does anyone know how to lean this thing out just a bit. I need every hp I can get (the car is a Saturn LW). HPtuners won't work on this car either due to the computer being an orphan or them not wanting to allow my vin I'm not sure. adn I haven't found any other tuning aide so I'm looking to this forum.

How do you know it's running really rich? What are you using to datalog?


15.3 @ 89.97mph, 14's on the way?

Well you could swap to Megasquirt. You could also put a AFPR on and lower the psi on the fuel rail.

So at wideopen throttle acceleration, what AFR #'s are you seeing?
