Black LS1 T/A

(I'm not talking about Torque Management or TCS here.)

Someone was explaining to me that on a later model Corvette that the throttle control is ?electrical? and there is a check by the computer to test that the throttle position coincides with the Air Flow monitored coming thru the MAF. He thinks this is killing his power with a supercharger he has installed because it senses air flow (thru the MAF) outside the normal parameters, and the computer cuts back the power.

Has anyone heard of this and if it is true, can LS1-Edit defeat this?

Thanks.

Part of the power reduction is the desired Air flow vs. MAF but there is another paramter that will control throttle and timing that is added to the newer autos based on torque. This is different than the tq parameter setting.
The car I tuned only made 200 RWHP with the blower when we first got it. It's now at 481 RWHP with headers/exhaust and a yank converter.

Hmmm.. so there could be something to what he suspects. It sounds like you zapped the problem when you encountered it. You refer to:

1. Desired Airflow vs. MAF

2. Some parameter that controls throttle and timing based on torque, yet different from the Torque Parameter setting that we normally attribute to Torque Management that cuts back timing.

1. Will adjusting the MAF vs Freq Calibration table (Trans/Fuel/MAF) compensate for this? Or is it a totally different parameter I don't see in my '98 F-Body version of LS1-Edit?

2. Is this setting ALSO a parameter I don't see in my version of LS1-Edit?

I don't know whether to tell him that LS1-Edit will help him or not? <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />

Thanks!

AFAIK these parameters are not in LS1 edit

Thanks for your reply.

At least it sounds like you have a good solution. I'll tell him about your experience with what seems to be a similar problem.
