I did a bunch of searching and I wasn't able to find answers for this so I thought I would ask. When tuning part throttle shift its pretty self explanatory but whats the relationship between wot shift speed and wot shift rpm? Should they match up? Which one does the pcm actually use or does it use both? What happens when set grossly different? (4000rpm shift at 70mph or 7000rpm shift at 20mph).
The other question I had, which might be related to my first question, is what could be causing my car to cut out whenever playing with wot shift speeds / rpm above stock? It feels almost like fuel / spark cutout but both of my limiters are set to 7k so it isnt that. It only happens right at the top of the gear right before the shift and it gets worse whenever I raise my WOT shift rpm to the point that the car cant even reach the shift point if set high enough! Its not a gradual thing its like it hits a brick wall. This is on a 2001 gt with mild porting on the lim, Hv3, PLOG, Catless Downpipe, Stage 1 tb, and rockers. My stock injectors are reaching 90% duty cycle so im on the verge of buying bigger injectors just so i can maybe shift at a decent rpm other then the crazy stock 5400 rpm shift!
I am getting no kr either (Seems like my pcm ignores the high octane table? Never see it command more then my low octane table at wot?)
Any help would be greatly appreciated! This thing is getting supercharged soon so I need to figure this out!
