MAP...Boost...I don't know...
I just got my Insight CTS the other day, and it doesn't read Boost...it reads manifold absolute pressure. Is this the same thing? It stays at 14 when idling and when I drive normally it goes around 18-20, higher if I really get on it. I haven't paid any attention to where it maxes out though.

It reads 14.

Average atmospheric pressure at sea level is 14.6959488 PSI. So I would assume that what I said is correct. MAP is absolute pressure and Boost is pressure minus barometer. I'm not entirely sure, I could check with my AE, but I'm not even sure there is a "Boost" PID. I suspect that most electronic gauges read MAP and BARO and do the math.

Ok so I just got off the phone with Edge...the guy told me that since I have another programmer, it has erased the VIN from the PCM and the Insight isn't able to read it and see what all parameters are available. He said they're working on an update to be able to enter the VIN manually, but until then I just have the basic generic parameters. Kinda sucks, but hopefully they'll have it fixed soon enough.

Andey...I have the Insight CS, and have had multiple discussions with Edge. I think they may be BS'ing you about why you don't have the boost PID. I have an '03 with no programmers, engine all stock, and my CS doesn't have boost. From what they told me, the engineers goofed up on the programming, so in their haste to get the CS / CTS out, they just deleted all boost software.
They have told me also that they are working on an update to get the boost PID available in the next 1-2 months. As far as the explanation about the MAP and boost, everything here is accurate. Your boost psi will be whatever your monitor is reading, minus 14, in your case. If you change elevations, you'll just have to pay attention to what it is at idle, as it may go up or down a few psi.
Can I also venture to take a guess that your CTS doesn't monitor EOT?

So if the PCM takes a dump does the tech have to program the VIN into the new PCM or does the PCM take it from the other modules???

It can be done either way. it will ask if this is the right vin you can check "no" and enter a vin

A new PCM would need to be installed and programmed by manually entering the vehicle's 'as-built' data by obtaining it through HvBOM.

Sorry for the hijack, but the people who know have just been chiming in.
I bought a second spare PCM with VXAN0 or VXAM0 strategy (early '03). I ran this briefly to make sure it worked and everything seemed fine, no codes and truck had the aggressive tow/haul back (original pcm has 06E17 recall flash). So the PCM does contain VIN and build data other than just 6L/Auto? I've been thinking about running the other PCM full time, but this makes me think otherwise.
