What bin file did you use? Cause you can't just use the 2002 L36 bin file cause it won't work.
I'm running the 2003 L36 .bin. Who told you it "can't work"? There are a ton of turbo/blown cars out there running L36 .bins with no problems, mine included.
You have to tune them, of couse (dropping spark 8-10*, changing WOT PE AFR to 11.0-11.5, changing PE enable to 35-40% TPS, and tuning the MAF/VE tables are a good start) but L36 PCM/.bins work just fine in boosted cars.

So what you are saying is you started with a L36 bin file and cut out and pasted in L67 parts to make it work and recognize boost?

Your link isn't working...but to "read boost"? I'm assuming you mean using a 2 BAR MAP sensor that can see over 100 KPA. There's no need for one. Nothing the engine actually uses it dependent on the MAP sensor seeing over 100 KPA.
The PCM doesn't need to "read boost" to do anything. Fueling is calculated off of the MAF and O2 sensor (which don't know what boost is). Commanded AFR/Power Enrich are governed by your Throttle Position Sensor percentage. Ignition timing is determined by RPM and MAP with no values over .92 KPA.
So...you don't need to "read boost" and I didn't paste anything from an L67 PCM to do this. I modified my fueling, timing, and shifting accordingly and that's it. Bottom line is that an L36 PCM can work with a top swapped or turbo'd car just fine with proper tuning.

So wait. If you hooked up a Aeroforce to your car right now (If you don't have one already) And you set it up to read boost, it would actually show boost? I would think if you only used a L36 bin and modified it like you said it would work yes but the PCM would not be able to tell you PSI of the supercharger on a scan gauge. Or does that have to do with using a 1 bar MAP? The question is why you can't just use the 2004 supercharged Monte Carlo bin and just take the tranny files from the L36 and copy them over the L67 files on the L67 bin.

Your PCM doesn't ever need to read boost. It does nothing. I'm using an L36 MAP.
I'm really not sure where you're going with this, but the bottom line is you can run a supercharged or turbocharged 3800 just fine with an L36 PCM. I'm doing it. My local buddy with the turbo'd 2004 Grand Prix is doing it. The guy coming up tonight with a top swapped Grand Prix for a CASE learn is doing it. Hundreds of people are...I'm not why you think you can't, but whoever told you this is wrong.
Because this would be more work and you don't need to. A boosted high compression L36 is going to be alot different than a low compression stock L67.

A map sensor is a pressure and vacuum sensor, so any map sensor can show boost, which is just an increase in pressure in the intake. With the engine off it will actually read atmospheric pressure (which is one way of testing for a faulty one). If you look at your aeroforce scan gauge or even a tech 2, you will see the that map reading is identical to the boost reading because their the same thing just with a different name.

Well the guy tuning my car said you have to use a 2004 Monte L67 bin because there are tables that you can't access using the L36 bin and he said its not the right way to do it. You can't use the 2002 Grand Prix GTP bin because the BCM won't match up. Using the 2004 Monte Carlo supercharged bin in a 2002 L36 PCM won't work because of the valve body the tranny won't shift correctly. So is it or is it not possible to put the 2004 Monte Carlo supercharged bin file in a 2002 L36 PCM and just delete the tranny files and add the L36 tranny files? Do I need to get a newer PCM, or is the 2004 L67 PCM the same as the 2002 L36 PCM?
