No Error Reported in the DTC tab.

Set the codes to NER. That does not disable the sensors functioning. More times than not especially with new sensors they continue to function detecting knock with codes set for them. When you have a...

Having burst knock turned off will not trigger a knock sensor code. Any real knock event does not set KS codes. KS codes come from a completely separate diagnostic the PCM runs on the sensors.

Does the TBSS use that same wonky fan the the I5 TB uses? We had a 02 TB I5 that the AC always sucked for blowing cold air when the vehicle was stopped. It was horrible if the vehicle was just...

Have you mentioned this to your tuner?

Search the forum for tuning with fuel trims. It's been discussed at length.

If it is going to run on narrow bands it should be tuned with narrow bands. Use the wide band for PE. The method of tuning idle and part throttle with a wide band of questionable accuracy has been...

Did you tune it in closed loop with narrow bands or open loop with wide band? If the latter there is your problem.

VIN, yes, serial, not likely. Like I said that is very common to see that on parts store remans.

epa.

If the main DOD switch is set to disable it will not run the test for the DTCs. I'm not saying it is good practice to leave them enabled but I have tested it on multiple MYs and OSs and if you just...

What inconsistencies are you seeing with known tested alcohol content?

No it won't.

And he runs the risk of getting the same thing he has now. Looks like a reman. Better off getting one out of a vehicle.

That is way too much for a 0411 PMC. And be aware no matter what you do it is going to cost 4 credits to program it. Then you are spending $275.

What is the 1200411 PCM out of the 2002 4.3L V6 4L60E Silverado going to cost you?

The PCM was probably a reman. They all seem to have those VINs and serial numbers. Also if you put your location in your profile there could possibly be someone local to you that could help with a...

We have E0 at just about every gas station in Okla. Many have E0 in 87,89,and 91. They will also have E10 usually only in 87. The Caseys stations have E15 they call Super 88.

Just use the stoich table from a FF truck. 14.1 is about the stoich for E10. And as the elevation goes up the less octane is required NA. Probably why only 91 is available in AZ.

Is the 93 E10 or 100% gas?

On a swap like that you need to state more details. You could of swapped anything from just a long block only to complete from top to bottom including intake manifold, injectors, throttle body etc....

If you just sat there without breaking the beams then you would not have run 2 seconds quicker. Just saying. Timing doesn't start until you break the beams. Reaction time only effects who gets to the...

So you don’t know anything about tuning yet you are turning for a customer. SMH.

Need more details to know if with the OS you are using if it is even possible.
