HP Tuners Is Awesome! Well, I just got back from my first reading, writing, and scanning session and I have to say that this HP Tuners software is great, the menus are well laid out, and the instructions for most things are pretty clearcut. I put off buying LS1-Edit for years because, frankly, it scared the hell out of me and came with no manual.
Anyway, I was hitting the rev limiter on my 1-2 shift and I cured that. I found two things wrong. One, my tire size was off a bit and this naturally screwed everything else up. The second thing I found was that the 1-2 shift point was set too high for the much bigger cam I just installed as this apparently increased the gap between the command point and the actual shift point.
I only have one problem remaining. Every time I do a WOT run, I throw the "P0748 - pressure control solenoid electrical" DTC. This started right after my new cam install. I know my tuner changed some line pressure settings (raised them), but I'm not sure whether the two things are related or not.
Anyway, does anyone know why this is happening and, more importantly, how I can fix it? It's not that big of a deal as I just clear the code using my DIC and go on my merry way and it's only during WOT runs that I throw it, but it's nevertheless annoying and I also don't like things not being "right."
Thanks!
Here are my present settings and results.
WOT Shift Speed & RPM Settings:
1-2 Shift: 34 mph and 6100 rpm
2-3 Shift: 67 mph and 6250 rpm
3-4 Shift: 118 mph and 6250 rpm
Actual Shift Speed & RPM Results:
1-2 Shift: 41 mph and 6214 rpm
2-3 Shift: 78 mph and 6224 rpm
3-4 Shift: 127 mph and 6245 rpm
My Shift Adaptation Time is set at 0.1 across the board and my Max. Line Pressure is at 95%.
Does all of this look ok? Any suggestions for change?
I'd like to get my shift points closer to 6400 rpm as the new cam peaks at ~6200, but I'll leave that for another day.

XTrooper...Not sure if dropping your line pressure will stop that error code from popping up or not, stock programming shows 90% for line pressure...Not really up on A4's and how to program them, sorry...But if the trans is operating properly and you are just throwing the code due to the programming...You can always disable the code using the HPTuners software...
Also, if you don't mind me asking...What is the max. timing that your tuner has you programmed at...Just got my G5X3 installed this week and won't get it dyno tuned for a while yet...I'm running my modified stock programming right now and actually have the thing running pretty decent...I'm currently only running 23 degrees WOT advance and was just curious how high some of the guys are running their timing with decent heads and a fairly good size cam...
Thanks...
Peace...Gman

28-28.5 at my WOT shift points with 0.0-0.8 KR.
P.S.- I'm not sure, but I think it's the base line pressure that screwed up, that or the "Force Motor Current" settings as they control that pressure control solenoid. I'm going to try putting them all back to the stock settings and see what happens.

I was showing I was only supposed to have 28* timing at WOT after logging today, I showed 30* with no knock retard. I just have a TR224 cam and stock heads.

Stock cam I'm running 29* with no KR on WOT. And that's with crap CA 91 octane 
Yeah the ZO6 and C5 Timing Table are pretty conservative compared to the F Body table.
