Some MAP tables for the 3800

[Chris@HPTuners]

3bar would be something like:

60 * V + 10

Thanks Chris!

Chris, can you take a look at this scan? Two things, either the formula you gave me is off a little bit or my PCM is off a little bit. There seems to be a discrepancy. The other thing is, if you look at the MAP voltage, there are points in the scan where the voltage is steady, at say like 0.67 volts, but the MAP value reported by the PCM flucuates between 2 or 3 values. Why does it do that?

Thanks,
Mark

can you post a .hpl file please, scandepot gives me a headache.

I'll post it up tonight when I get home Bill. Hopefully I'll be able to try that bin file you sent me too.

Old thread....I know.

I'd like to change my stock 2 bar map to a 3bar map to make my boost gauge (Regal) useful above 14.7psi. I think I'm around 17-18 psi right now and I don't have room for an external gauge.

Am I understanding this correct?

The only reason to breakdown the assembly code would be to make a 3bar more useful above 29.00psi? The stock maximum map reading in the PCM code is ~200Kpa (or 29.00psi). Like I said earlier, the only reason I'd like to use a 3bar map (43.5psi) is to make my stock boost gauge functional above 14.7 psi in my Regal. I would settle for a 2.5bar map too, I never plan to run over 20psi as it sits.
