was modifying me primary ve table, and noticed there was a secondary table. When is this secondary ve table used? Thanks,
Bryan

 

I believe it was for open loop or PE fueling PW in early PCMs. The overall pattern is the same with Less precision in the secodary table owing to fewer cells - MAP/kPa axis. Many/most of the MAP cells (40, 50, 60, ...) are identical between the two tables (primary vs secondary).

Maybe one of the Gurus will jump in .....

thanks for the feedback. If anyone knows what circumstances call this table, i'd appreciate it.. this is a pcm from a 2000 ws6. Thanks

 

So when tuning for idle, there is no need to do anything with this table, correct?

 

from what I've been reading yes that's correct.

 

No need to change at idle.

secondary VE is only used during failure (such as MAF DTC) on early code.
