MSPNP base map. Map showing low ambient kPa. WTF?
 

According to the megamanual, engine MAP should be around 100kPa when not running.
Mine is reading 66kPa.
Is my sensor busted, or is there a way to calibrate it?

I'm nowhere near 10,000ft. Closer to 1,000

Houston we have a problem.

There is no way of calibrating it that I know of. Only thing I can think of is the constant baro correction is malfunctioning causing it to read low.

EDIT: Has it registered low since the last time you flashed firmware/burned msq. If so your ms could think you have a 2.5 bar sensor when the PNP has a 4 bar. Check the settings in the MSQ and in the megatune configurator.

Paul is having the same problem as well as a friend of his. I'm sure he'll chime in here.

yea but pauls is barely off if i remember correctly. thats waaaaaay off lol

I would be the friend of paul's thats seeing an odd reading too. mines at 91kPa. I run a 94-95 MSPNP. Your's is WAYYY off.

I think you may be on to something here...

Ok I'm an idiot.
 

I just switched to hi res and I'm pretty sure I selected the 250kPa sensor. I'm guessing this would be the cause of my crazy lean readings off idle, and really fucked up accel enrichment numbers.

all the newer MSPNP's have the 400kpa (4bar) map sensors.

66kpa is the value you will get if you set the 2.5 bar map when you indeed have the 4bar

Hey I'm getting pretty good at this diagnostic lark :D

Confirmed.
Changed it with configurator.
99kPa now.
Thanks

sidenote: You'll idle at 48-50Kpa if you have a 2-bar and select 4-bar :)
