I have seen writeups that tells you to disable Power Enrichement while tuning by maxing the kpa enable value to 640 so target afr doesnt jump all over the place .... and have seen others that leaves PE untouched .
Whats the best way for tuning VE?

Leave it active, why run the risk of hitting high load operational area during your tuning session and not have the extra fueling. Activating enrichment during tuning will generate a fueling spike, but you can filter that out using the commanded Lambda (or AFR if you are still using it) in the histogram. It should represent a small portion of you tune data and shouldn't hurt your accuracy very much. Normal process is to collect steady state data from idle and up and whether PE activates or not, the lambda error still represents your MAF or VE error at those cells.Originally Posted by torker
