So I have an 04 GTO, with a magnacharger.
I installed the 2 BAR OS this last weekend along with a 2 BAR MAP (12580698)

In tuning and testing, everything seems to work ok, but the manifold air pressure never rises over 110kpa...under WOT it goes right to 110 and then stops.

I would think if the wrong sensor was in there, the car would run funny with a 2 BAR OS and 1 BAR MAP....

Now keep in mind I live at altitude 6000', and I also have a cam and LT's which combined will drop my boost down quite a bit...

But it seems odd that the MAP reading goes to 110 and stays there from 3K to 7K, without dipping or going above.

What do you guys think?

Are you running version .16? If so have you checked your table display to see what it is saying?

Check out this thread if it reads fine in the table display but incorrect in your histograms

If thats not it, please post an .hpl file here or on our forum & I'll take a look for you.

.14
Should I upgrade? Can I re-apply the OS patch? Is there a known issue with .14?
The data seems the same everywhere, in all the scanner tables/histograms, as well as the Aeroforce gauges I use.

For some reason I can't get to HPTuners.com today, but ill keep trying.

There are very few issues in .14 so I would stick with that until .18 is released in the next week or two.

Post one of your .hpl files here using the manage attachments feature & I'll take a look for you to see if anything stands out.

Yea, post up your logs and maybe even the tune. Did you grab the 2 bar map sensor pid and remove the standard map sensor pid in the scanner?

Nope, sure didn't. I will double check that this evening.
Don't remember seeing that in the demo flash file.
Its my first 2 Bar, go easy on me

Maybe thats all it is.

Well I checked the PIDs and you were right, still had the old one in there.
You were right foff, I did skip the last 3 steps. No need to be snippy though

Thanks for the help guys. Next time ill read the directions more thoroughly.

after some additional logging it got up to 120kpa so at least its working better now.
damn thin air messing up my boost levels!

thanks again for the help.

make sure your not logging maf SAE otherwise that can skew that data...post up an hpl file if you get a chance so we can look it over to make sure things are all kosher for you.
