I'm going to buy EFI Live with the CTS Insight pretty soon, I have read that the CTS insight will only read 22 PSI on the LLY. Can the MAP sensor be changed to a 2006 LBZ style and read higher pressure.

is the issue with the physical sensor or the ECM? I know that's when they switched from Delphi to Bosch. bump for you

It only reads that boost number because it isnt really measuring the boost, its more calculating the boost based on the air flow past the MAF. Get an actual gauge if you want to know the real boost numbers. The cs is still good for everything else though, especially controlling your efi tunes.

I know that the lly has a MAP sensor on the intake that reads boost to 22 psi. and the LBZ reads to 40 something. The MAP sensor is in the intake manifold attached to the driverside head. The MAF sensor is in the intake after the filter.

Yes, any good EFI Live tuner can change the map sensor. On my 2004 LLY I installed the LBZ turbo mouthpiece and LBZ Cold Air Intake to match. Because of the larger diameter piping to the turbo and more air flow the MAP sensor would of been off however who ever tunes your truck should be able to do this.

that is the MAS mass air flow not MAP Manifold Absolute Pressure, these are different things

That's a good question and I wish I knew the answer for certain. The boost should be read by the ECM as the difference between the MAP and Baro sensors (nothing to do with the MAF sensor at all obviously). I think the LLY and LBZ MAP sensors are different (I believe LLY is 2.5 bar while LBZ+ is a 3 bar sensor), but again hopefully someone more knowledgable about it will chime in as to whether you can get them to work or not and if any wiring or scaling would be involved to make it work. It would be a nice mod if it does fit though.

Try contacting Ben (Duratothemax) and I'll bet he's got your answer.

Yes MAF mass air flow, still not what I need to know. MAP Manifold absolute pressure is the one I need imformation on.

Just trying to keep the terminology correct to avoid more confusion, just how I am.
Did you try MTL_Dmax's suggestion? He thinks Duratothemax might have the imformation you need. teehee
