I've never seen any advantage to having the pe-tps, so for the last year or so I've made the entire pe-tps table the same in all my chips so there wouldn't be any issues about the tps not maxing out at some magic voltage, and they run just fine at part throttle and during tip-in. I've also played with how much fueling my car seems to like at various maf levels, and what I've seen is that the same pe fueling works from low boost, maf less than 150, to just before the maf is pegged, say 245 or so to be sure the maf isn't starting to go nonlinear like some do near 250-255. That's why I like the maf trigger for the blm lock. I tune up at low boost to keep the maf under 245, get the pe-rpm table right so spoolup is good and partthrottle doesn't knock, then add the blm lock and vary the value I lock to to control how much extra fuel I add in when the maf is pegged. Just my personal philosophy on how to do it. Oh, I guess one of the days I need to go ahead and share the code patch I use to lock to different blms in each gear so I can keep from flooding it in 1st and still fuel it in 3rd, hmm? Anyone interested? It is more work to get tuned up, and you have to take into account the different wgdc's in 1/2, 3rd, and 4th. Damn, I'm lazy, though :-).

While we are sharing and since we agree the pe tps can be dropped anyway, here's probably the best idea I've had the last couple of years. If you look at the chip, the pe tps table is right in front of the pe rpm table, and together they would make a nice 17 entry table. Take out the pe tps call entirely, change the pointer address for the pe rpm table to the address of the pe tps table, change the pe rpm lookup subroutine call to the one for a 17 entry table, and presto you should have twice the rpm resolution in the pe rpm table. Whattaya think? No, I haven't tested this yet but it is sure on my list of things to get to. I've read through the table lookup subroutines and I think it really is this simple. If anyone does this, or even just reads through the code for the table lookups to make sure where to jump to, please share with us.
