Default Lml s369 & p10cf

I rebuilt a local guys LML that cracked 4 pistons. I have been having to hold his hand ever since. Stock engine and fuel with a wc Fab s300 kit. . Latest issue is it's setting a p10cf. IAT sensor 3 not plausible. It's reading -40*f. Which I believe to be normal since it's not being used. Here's the problem: I'm fairly certain that sensor is in the outlet of the stock turbo charger which obviously is not being used now and hasn't been for 2 to 3 years. Ppei guy just told me it's not their fault since it ran before without the problem. Has anyone ran into this or can you confirm that IAT number 3 is that sensor?

Is the sensor unplugged?

Yes. The thought crossed my mind to steal one off of one of our trucks and try it

Why can't they simply turn it off? They have "full control" of LMLs. Or so they say

IAT sensor 2 is the one in the turbo. I just unplugged it on a 2011 here at the shop and it went to -40*. So maybe I jumped the gun getting ahold of ppei. IAT 3 must be somewhere else on a 2015. This 2011 only has 2.

I'll bet sensor 3 is the one in the plastic tube between the intercooler and intake. Post intercooler temp basically. Would make sense anyway.

Ok, I just found that 2011 & 2015 sensors are not the same configuration. For all years, the one in the plastic ic pipe is called the charge air cooler temp sensor. On this 11, it then has 2 iat sensors. #1 is the maf, #2 is the turbo outlet. Meanwhile the 2015+ has another sensor right by the maf, I think it's for air humidity. But it is iat #1, maf is #2 and the turbo outlet is #3.

Now I can argue with ppei some more

I had a 2011 from Rhode Island that installed a wherli s366 kit with ppei tuning that couldn't finish the truck on his own and get it running right. After finding and fixing all the leaks, I discovered that wherli's kit didn't include the proper size bungs for the IAT sensor after the turbo and CAC temp sensor. They only put in NPT bungs. After going back and forth with ppei, about the possibility of tuning one out or rescaling the table to match a lbz/lmm style sensor, which I could tap the bungs for, I was told the logs looked great and they didn't see anything wrong with how it was running and that the tuning changes to correct the CEL and intermittent reduced power condition were going to be extra charges. The kid came and picked the truck up because he was in a bind, and I forwarded him all the emails so he could pick it up where I left off with them, or he could take it up with wherli and get the piping replaced...not sure what happened with it. It was a rotten deal all around.

Ppei sent new tunes for me that I put on his autocal. I haven't had him back to reflash yet but I have him driving with the sensor plugged in and zip tied up to try.

The code will not come back with the sensor plugged in and just zip tied out of the way. But today I reflashed the new tunes and removed the sensor and all is well thus far.

Good deal. So far what little I've dealt with PPEI has actually been pretty good.
