Can someone take a look at this and tell me what's wrong?
I have a braineack built ms2.
To calibrate the MAP do I select MXP4250?
What's showing on tuner studio is different from my gauge.
Also have an AEM afr gauge.
Manual says
0.00 v 10.0 afr
4.99v 19.98 afr
But the values does not match up with the gauge either.
Any help would be greatly appreciated. Trying to get this running to go to MRLS this weekend.

What exactly are you running for AFR?
I had a gotcha moment earlier on my AEM UEGO when reinstalling ms3x after months of having stock ecu.
When you power it on, what do you see for your P-mode if any? EX P0 or P4?
Some have the ability to replicate narrowband output, and I left mine in narrowband mode for the stock ECU when I put MS in.

Thanks for the help guys.
I got it running and had a blast at MRLS.
Its still not perfect though.
At least I got rid of the dips in power at higher rpm.
Running an AEM 30-4100 in P0.
Which setting do I use to find MAP sensor reading?
i was using boostpsiggauge.
should I be using engine MAP - mapgauge instead?

Point is, you should see around ~100KPa with the engine not running, and if you are around sea level.
If you are not, then you have wrong map sensor settings, a faulty map, or bent map hose.
