Hello friends,
I have a 07 GT500, with a kenne bell 2.8 with the twin 75mm throttle body. The car is on the 2.75" pulley and should see 21psi roughly. For fuel it is a return system with 1000cc deatchwerk injectors. I was having issues rolling into W.O.T and made adjustments to the effective area table and predicted area tables.
Since then, it seems to have improved, but i notice an odd point in the middle of the pull where the maf seems to time out. Trims are safe up to that point, in most cases they are pulling fuel...
I have attached the log file and if you look right at 1:23, it is reading 84.38lb of air and drops 1 second later to 1.29lb.....
I could not feel anything and it seemed to be smooth so i was paying attention to the road looking straight ahead. Seems to be occurring at 5200rpm. I have my timing down very low right thankfully, but this has me scared. I noticed my throttle value is still not quite 82%. I would love any and all input on the calibration I have thus far And what you think might be causing this issue.
I have loaded my calibration file and the log. Thank you all for your help. effective area redo with driver demand and dashpot adjusted wot successful.hptwot 6000rpm maf drop.hpl
