Here's mine. This is on a 1999 C5 in 1st gear. It didn't hit REP mode on this log but it does at other times. You can see that the APP is at 108% but TPS is 100%. The different throttle PIDs don't...
A quick video shifting 1-4 actually using the shifter, gas, and clutch. I wasn't letting off the gas fully, but you can see the throttle blade slapping shut.

If you keep it pinned all the way down and in my case at 108% ETC Pdl, it appears to stay wide open with KOEO. Just a 1% change (going to 107%) causes drastic changes...
Are you saying that TPS was greater than 100% or the ETC Pedal value was greater than 100%? I'm seeing the same thing. ETC pedal goes as high as 108% but TPS or ETC never goes above 100%.
Did you...
What codes are you getting?
*Important Info*
This is the code I am getting:

Here is everything that has been changed to eliminate REP mode and it still goes into #HPTunersREP mode.

I pulled the charge pipe tonight and verified that the throttle is opening 100% when pressing the pedal to WOT. I tried forcing the throttle into a position and got a P1516 code and REP.
I sat in...
Should I post up the associated log files?
Is there anything else that needs to be logged to diagnose the issue or is this something that can't be solved without having special access via HPTuners?
Any idea why ETC Pedal is at 107%

Here's one where I basically stuck with the plan. Just as the clutch engaged, I paused the pedal application but then kept going. The tires were spinning hard and I let out just before tagging the...

Here is the 1st time it happened today after I went and got the laptop.
This is at the launch and engagement of the clutch. You can see that I had the...
If it's not one thing it's another. :doh: I was planning to go to the track today, but noticed the clutch seemed to be dragging. I did a fluid change, bled the clutch, adjusted the tick master...
Lot's of rain this weekend, so the tracks were closed. There may be a window of opportunity on Tuesday night depending on how the weather plays out. I'm really wanting to test it out but the only way...
I appreciate you relaying your experience. I am using a stock 90mm LS2 TB with the correct harness. As mentioned, it doesn't happen on the street or dyno because I can't generate the type of load and...
I disagree. If the coding is there to make it all work and enable REP mode, there is a way to also disable it.
Thanks. A friend of mine pointed out the "Max rotation vs pedal" change to me last night. I'll check the other things that you mentioned above. Another thing he mentioned is the drivetrain abuse...
Thanks. I'll have to wait till the next trip to the track. It only does it during the launch and I have to be on slicks on a prepped surface to hook the power.
Yes, I've learned after doing...

I listed the codes above. It's tripped 1514, 1515, P0101, P0103. I've made passes where I don't go full throttle at the launch and cut a 1.58 60 foot and it will make a clean pass all the way down...
