I am tuning a 2002 corvette with a LS3 480 hot cam replacement engine,
Problem I lost ETC of 100% somewhere while getting the correct mixture
After changing, IFR, Engine Displacement
I first put it in SD and tuned the VE table
Then turned on the MAF and it was way too lean, so I increased the MAF table too get the mixture in line, and now getting to WOT tunning and the ETC is not at 100% as it was before, it dips lower around 4,000 rpm and comes back up some towards 5k but still low? 70-80%
I increased etc predicted air flow but I don't think it helped, or I did not change it enough
Any thoughts would be appreciated
