It might help if you told us what the code is.
Attach a Tune and a Log if possible.
Is the commanded AFR 14.7 the whole time or are you getting into PE?
Check out the CT Downshift Torque Management.
The o2s wont do anything but read whether you're above or below stoich, regardless of fuel.
If you change the tune's stoich setpoint to 12.0 it's going to think it needs to add more fuel to...
Right Click and Drag
The injectors are numbered by firing order, not cylinder position. Or so i've been told
So:
1 = 1
2 = 8
3 = 7
4 = 2
5= 6
6 = 5
7 = 4
Asks for help.... argues with the help...
The "valve" in the intake description is correct. It's also correct that you don't have one.

No
If it just needs to start, keep it out of boost and it doesn't need a supercharger tune ;)
If you do the 2 Bar upgrade it will give you a standard VE table to work with, if that's what you are used to.
Must be set to fail on 1st instance. Just uncheck SES if you dont want to see the light
wow! that sucks
I'd like to think I'd notice something was up after one or two pistons had the sides burned out instead of continuing to drive the truck :lol:
Does it have any trouble codes present when it happens?
Timing is sensitive to cylinder pressures, not so much RPM. Its not uncommon for higher rpm ranges to take more timing than mid range will without knocking
It sounds like the tuner added timing until it knocked and then pulled it back a degree or two, which is how most people do it.
If knock is only present when you add more timing, it is probably...
I have no personal experience, but I'm going to assume they need to be before your exhaust is merged. Otherwise it won't know which side needs adjusting to correct the fueling.
In an extreme...
Look up threads on Prediction Coefficients. It seems most zero them out and this issue goes away.
Used a Tech2 to reload the original 4.8OS back into the truck, then did 2 bar OS mod to it and copied my changes back in. The issue with the large Pulse Width/IDC is lessened after this, but still...
Update: As i've richened up my cold start, i am getting the crazy high pulse widths sporadically while idling. So, what ever is causing the pulse width to jump, is tied to demand.
I've put my IVT...
I'm not sure if the IVT Gain table is the cause or not, but if it is, I've made it worse in the last week, haha. I've been cranking it up because the truck has been lean on a cold starts even with...

Sometimes its better to drop back to the stock tune and start over when you develop a weird problem. Save where you're at, then flash stock and start dialing it in again (Obviously, excluding the...
Support sent me this in response to the TPS charting looking like that, and they are correct, the issue corrected when i followed their instructions. "With the generic parameter it is trying to pull...
