2 Bar map maxing out at 105kpa?

[Rory]

We are tuning a customers Custom Weld boat with a Supercharged 6.0. Boat came to us not running well. I installed a PCM from a 2002 Express van and upgraded to a 2 bar OS. I am having two issues currently...
1. MAP sensor is only reading up to 105kpa under full boost of 7psi.
2. Cylinder air mass is only reading up to 32 g/cyl.

I have searched and obviously I am not using the correct search key words to receive the information I need. I have a feeling these issues are related?

Thanks,
Rory

log the 2 bar map sensor pid.

[Rory]

Bill, what data are you looking for? In order to log this I need to put the boat back in the water. I was hoping to figure this out before heading back out.
Thanks

[Bill@HPTuners]

I'm not looking for any data, I'm just telling you what you need to do ie log the 2 bar map pid.

[Rory]

Oh. You are right, initially I was not using the 2bar pid. But since have been, however the g/cyl only goes to 32 and map still max out early and cause the timing to drop to 0?

Thanks for the help.

[Rory]

Bill,
I verified the 2 bar pid on my scanner, I did not have it set up correctly, but did try to "load vehicle defaults" which loads the 2 bar pid. Now I am getting 0.00 (key on not running) for MAF and MAP readings, also hooked up a pump to the MAP and see no changes in the displays?
Do I lose resolution on the timing maps which use G/Cyl for load instead of Kpa?

Delete the maf pid that you likely still have in your table display(as outlined in the help file www.hptuners.com/help which is a must read for all users new and old alike).

[Rory]

As it says in the HELP file I have deleted the maf pid. Here is a scan file with with 10psi applied to the map.

looks normal for KOEO

[Rory]

So what you are saying is if I start the engine (which I can't until I put the boat back in the water), the MAP sensor will begin to read correctly? I understood that the MAP should show current atmosphere (i.e. around 99kpa at my altitude) while in KOEO? Here is a log with the std. PID (non 2bar), you can see at 5.5sec the scan max at 105kpa (pressurized map to 10psi).
Also, what about the timing map and G/CYL as load?

Thanks

Looks normal for not logging the correct pid.

[Rory]

So, again with 2bar pid the MAP should read 0 KOEO?

[Bill@HPTuners]

correct

[Rory]

Ok, great.

Any thoughts on why the tune will pull all the timing out above atmosphere?

[Bill@HPTuners]

Once you get the correct pids working post a scanner log & the .hpt file.
