Baro Reading Low
Howdy,
Turbo first timer here and I got my car up an running. But I have found that my MAP/Baro reads very low. With engine off but everything powered my baro reading on any of the tables in Tunerstudios read at around 80kPa. But I live in Annapolis,MD where I'm pretty sure atmosphere is at 100kPa. In addition, when I go into boost (momentarily) It will still read low compared to the boost gauge. So as of now I am currently not driving the car until I can figure this out. Currently the Megasquirt and the boost gauge are sharing the same vacuum line but my boost gauge is reading correctly since it reads 0 when the engine is off while the megasquirt is reading a slight vacuum. Would having the megasquirt having its own vacuum source possibly fix the issue? Any ideas on what I should look into? Edit: Its an mspnp pro. Thanks, Cory |
do you have it calibrated as the correct MAP sensor? 4bar vs 2.5bar?

Oh wow...So it was set to GM 3-Bar/MPXH300 map sensor.
So I set it to the MPXH6400 and now it reads the correct kPa. Looked up the mspnp3 and its a 4-bar map sensor. Is it correct to assume that this problem is fixed? |
sounds like it!
