Hello -
Question. I'm trying to tune my VVE tables. I've tuned the MAF by logging MAF hrtz with my LC-2 wideband "EQ Ratio Error (Math). So I thought I could do the same for VVE. What I did was set up a table to match my VVE. RPM on top with MAP sensor on side both have same values as VVE and selected the parameter "EQ Ratio Error (Math)". I failed my MAF sensor, disabled long term fuel trims, DFCO, and cats overheat, disabled, copied spark tables into low spark table, and went driving. Once my engine warmed up I commanded open loop with the scanner and started logging. I'd get errors from plus 8 to -10. Id copy the data, paste special/muliply to VVE and hit that coefficients (think that's what it's called.) Then I would copy and paste that table to the other three in the drop down. I've went through this about 10 times and at this point I think I'm doing something wrong or going at this entirely wrong as nothing is improving. Maybe a percent or three if that. When I did this with MAF, about 5 drive cycles and it was perfect.
Truck I'm tunning is a 09 Silverado.
Any help would be greatly appreciated.
Thanks!
