RPM not showing above 4000 RPM
Finished my DIYPNP MS2 extra install this past weekend. Got the car, what I thought, running pretty well. It's an exhaust and intake 1.6L car (around 1950lbs) and the MS really freed up some midrange torque in the car. So I got it to idle well (still high ~1200) but no tip-in stumble that I can feel.
I went to do a few pulls on the interstate and got back to read the logs. For some reason the RPM shows 3440 max and I only reach 87.5 kPa, which seems odd to me. I don't really know how to fix this issue or where to look.
1.6L
intake
exhaust
IAT
time 295 to 315 is the cleanest pull.

I will have to check the MAP signal later on this week when I get home, but I am kinda in the mountains, the Appalachians.

Barometric correction COMPENSATES for the ambient pressure not being 100 kPa; it does not make the ECU pretend that ambient pressure is not 100 kPa. Atlanta is not exactly high up in the mountains, and ambient pressure here is usually around 95 kPa.
It may be that something simply stopped the log before it was revved to redline.

I am extremely happy with this MS unit and I love the support the community, and company, has behind it. Again, thanks for taking the time.

Just incase one of you newer guys to tuning is reading this thread during a search. I found some great information on the DIYPNP site explaining how to tune AE ("acceleration enrichment").
DIYautotune VE enrichment tuning
....and Aidandj is right, it does, on a basic level, read get a vTPS.
