Trouble tuning my 2.9 Whipple Superchared L99 Camaro SS with a BBK 95 mm Throttlebody
The problem I am having is slight part throttle surge at low TP settings below 36%. RPM range from 800 - 2000. If you are really light on the throttle accelerating or coasting there is an slight surge of +/- 100 rpm. The cam is stock and car has shorty headers. The tables I have been changing are:
B1650 - Stock: 5636 Tune: 6279
B2806 - Stock:.0244 Tune: .0153
B1829 - I increased the minimum idle airflow table and it has helped.
B1845 - I decreased values slightly
B1843 - I decreased values slightly
As I data log I noticed the TP stays completely steady at whatever TP I am at, but the car has a slight surge. It feels most pronounced in 2nd, 3rd, and 4th gear. The car is an automatic. I also noticed as it surges it seems to be bouncing up an down in timing a few degrees. The car idles pretty smooth. Any Ideas? Are there any parameter that I should be logging to find out what's going on?
