hello alll i am currently having some trouble tuning my car i have a 2000 chevy cavalier ld9 2.4l turbo it has good lowend torque
but toward higher rpm it feels like it stops pulling.. this happens above 5 psi boost. i am tuning with the alpha n computer if this doesnt work is there
any way i can switch to the speed density tune ?? or the gm reflash
t28 turbo
36lb injectors
Not much.
You need to log specific items and do long smooth runs.
Erratic stabbing of the throttle is not going to get any accurate results.
Do you have pro or standard Hpt?
Wideband is a tuning tool, with out it hooked up to HPT it is really just a useless show piece in my opinion.
You are going to want to tap into Connect C1 Terminal 49 to PCM which is the AC pressure sensor.
Install a switch in that ckt to input your AEM WB signal.
Do a search on forum to get more info on that.
