Sorry if this has been covered before but the search feature doesn't allow me to search for "WOT" as it's too short.
Anyways, I have my car's part throttle tuning done and it idles and drives around town perfectly. Now I'm going to move onto the WOT tuning. I feel kind of dumb for asking this, but what's the general process? My limited understanding of WOT was that WOT is handled via the Power Enrichment tables, the main one being table {B3618} "PE Modifier Based on RPM". I also thought that under PE conditions, the car is in open loop. Wouldn't this mean I have to have my VE table dialed in for the PE Modifier table to be accurate? It seems wholely unreasonable to do as the only way I know to tune the table is with the AutoVE method. There's no way I'm putting my car on a steady state dyno and holding it at a bunch of different 6500RPM cells for a minutes at at time.
This leaves the use of the multiplier as an inaccurate factor (i.e. change the multiplier up or down until the desired AFR is measured). This means that I can't change my desired AFR then unless I redo the trial and error method again correct?
