I am hoping someone could help me with this. I have a supercharger 5.3 in which I am trying to tune. My steady state MAF and VE values appear to be within less then 10% error. I am trying to tune transient performance off idle and also off cruise. To do this I am trying to adjust the fuel puddeling values vs. IVT however when I try to log IVT I get an error with the scan tool. The IVT when logged through the PC counts down from -200Deg C to zero at a rate of approx 1 deg/sec. When trying to log black box the scan tool returns an error and won't log data. The vehicle I am working with is a 2005 GrandPrix GXP. Any help on this parameter would be appreciated.
I am also looking for help with my stock traction control. I have the traction control enabled in the sofware however traction control never comes on even with large wheel speed differences between the front and rear tires. I have tested the stability control and that still appears to be working.
Thanks for the help.
Regards,
Chris
