ETC scalar set to 8100 max throttle set to 90 %, AEM x series wideband installed, will log tomorrow.
When ETC area scalar was set to 8100 truck hesitated to stay on and died multiple times, set it back to 5636 and drove better. Added AEM x series wideband and MAP channel. Left max throttle at 90%. Im throwing in the towel.
When you increase the scalar you need to then add to your BRAF table.

are you sure the throttle body isn't made by NW? He said he does them or did them at least for KONG.
If it is.. the scalar should be left stock.

^^^ Either way, I don't think the scalar or the P2101 settings have anything to do with the code he's getting.

The P2167 probably should be checked to the correct service manual, at least the description. An internet search returns that as "P2167 Throttle/Pedal Position Sensor E Maximum Stop Performance".

I messaged Kong about who makes their TB, I'll make the adjustment on max throttle to 85% and log it again.
I got an email back from Nick Williams, and he said P2167 is a pedal code to check wiring and/or replace pedal. Pedal ordered will be delivered tomorrow.
Might want to ask him how to set that tb up too. I thought Nick was only using the stock settings on the 103. Didn't know he started doing that on all of them. Airflow will change a lot with the opening throttle on that one. Your throttle was way under pedal. It shouldn't be like that, but it's possible a bad pedal sensor will skew the ecms inputs.

Per Nick Wiliams
" start with stock ETC scalar, it may need to go lower. WOT should be limited to 95% with a 2008 corvette E38 PCM.
Stock ETC scalar 5636.

I thought it was using the stock scaler at that point, but if it was 8100 I could see the pedal being over throttle knowing how Nick set the tb up now, just perhaps not that much. I was thinking the false inputs from pedal might be throwing it off or the etc scaler being quite a bit too big or I guess in this case possibly even both combined. I just know once they get too far apart it'll throw it into REP and this one was starting to show problems around 30% pedal if I'm remembering correctly.
Personally I don't agree with making the tb's mechanically work with stock scalers or use smaller than stock scalers. Guess it would be more safe that way, since it's technically lazier and not overly aggressive granted the tb motor has the capability of really holding things in place.... Don't know. Guess as a whole or big picture it's better, but personally I believe in having all of the throttle and airflow models set correctly instead of having a component work around the tune.

The new NW throttle bodies are throated to flow like a stock throttle body until a certain point. The throat and where the blade sits works like a cable throttle body bell crank. This means the throttle body is much more consistent and reliable at low throttle angles. This is a superior design. It's not a lazier way to do things.. its is a OEM way of doing things. And its why his throttle bodies can go on with no fuss.
A straight bore throttle body.. or even a stock one that is ported does not behaive like this. So say at 5% blade opening vs 6% there is a HUGE difference in flow. This causes inconsistent behavior.
As I understand it.. there is a table in the ECM that characterizes blade position with airflow. Looks like a MAF table. The scalar is just a global adjustment to that entire table. Not the low blade positions we would need to edit to make up for a throttle body without a proper throat. The scalar doesn't just trim idle. It makes the whole throttle range more or less sensitive?

I initially read it as a TPS throttle body too high code. It is a pedal code. this should take care of it.. or at the very least it isn't a TB problem. It could be still wiring or incomparable pedal with the ECM's OS. It's best to use the same pedal that the oem application did with the tune file you are using.. So 08 Corvette should use a 08 corvette pedal.
