I can add changing the tps from the sae to none sae improves accuracy and makes dialing the tune quicker.
Well it gives you a wider range and pinpoint accurate making getting your fuel trims dialed easier. Now when you are doing the ve tuning I like to start with my cell counts at 5 and work my way up to 60 starting from the bottom up builds nice crisp ve tables resulting in better mpg and drive ability. Them I hook up the wb and make some wot runs dialing in the pe side. Then you can move on to timing and a quick ve touch up as well as pe. This is my way it might not be right but it works for me.

Care to elaborate?
Ok, could use a little advise here.
Have a 97 cavalier that we built for circle track racing.
High compression, big cam 7000rpm and had it pretty close tune wise.
Then got some more speed at the track and eventually ran out of fuel and burned up three and four. Injector duty cycle 100% for easy to long and leaned out via wb.
Got rid of the 19 pounds sidefeed injectors and put 24lb top feed from a f150.
Then I had a bad tps while trying to tune, had a bad pin on my cable, but getting closer.
Then after some bad machine work the wrist pins walked out and ruined the block.
So, now new motor, new sensors good to go.
My questions are
1 using the formula new/old times rate for me real close and drivable with the 24lb/hr.
But in pe it is a little lean a well as in some of the high speed ve tables even though the ve table is at 100.
Is it better to change the constant or offset the ve tables?
I'M THINKING that I want to offset all the ve tables by 10% and add only in the cell I need to.
Can't find enough information for the offset vs constant.
Am I on the right track? Is there an easier way?
Thanks in advance.
