Very strange issue with tunerpro

For the last few weeks off and on I've been trying to make small changes whether it be to shift points, cold start AFR's or MAT correction and I've my "good burn" success rate has been slim. I will burn a chip and it won't work. Reburn something else and it will work just fine. By not work I mean it will flood the crap out of it on startup. Finally tonight I sat down and was making a few changes again and found something odd. I wanted to set my open loop idle table to 14.7 across the board so that it idles at 14.7 in open loop (thats what I'm running in now) once its warmed up and then scale my choke AFR's based on the set open loop idle AFR's. So I set it to 14.7 across the board and proceded on to the AE TPS correction vs MAT table. With a wet flow intake that gets heat soaked to around 140+ degrees easily in less then 30 seconds I didn't feel like it should delivering the full blast of AE TPS and it was causing a bog on tip in anyway. I set it how I wanted so it basically flattened out past 56 degrees celcius and AE TPS would be virtually the same from then on. Went back over everything to make sure it was how I wanted it and to my amazement open loop idle had gone from 14.7 to single digits on the first 7 or so cells. I reset it and saved it. Checked over the bin again and found the AE TPS correction vs MAT on the last 7 or so cells had changed dramatically. I fiddled with it and finally realized that these two tables for some reason are overlapping each other. The last cells of the AE TPS correction vs MAT table is being overlapped by the first cells of the open loop idle table. The numbers don't match but changing one causes the other one to change and I don't understand why. The address for open loop idle is 4BA3 and AE TPS correction vs MAT is 4B9A. I don't see why there would be any connection between the two and can't figure out how and why they ever got connected like this. If screen shots will help I can post them if you like. I would like to be able to edit both tables entirely seperate from each other but so far I'm clueless.

Re: Very strange issue with tunerpro

Guess I can't deleting the opening post but found the problem and lesson learned. Went to the hack and I'll be damned if it doesn't go open loop idle and AE TPS vs MAT right below it. Somehow when I put the MAT tables into my XDF I managed to look at the wrong area and added too many cells and somehow that caused the crossing over between the two tables. I don't even know how I did it but I did and it worked.
