Default what should I do about baro correction?

I have about 200' elevation change from one track I attend, to the other. I also drive through mountains once or twice per year.

I do not have baro correction with my mspnp.

What should I do to keep everything safe? I'd hate to blow the built motor over something stupid like this.

200 ft is nothing i have that leaving the valley where i live with no problems. I would take a deep breath and just try the setup on a test run through the mountians nice and easy to see how it does if it has no ill effects then you are good to go if it spazzes out then upgrade to a mapdaddy. Has your unit shipped yet. FWIW we recently went through a low pressure spell storms etc other than abit of a wonky idle my car ran fine even though natural kpa shifted to 95 or so instead of 103.

I've had my unit for a while, it was in the first batch. I have not been home yet to set it up though.

I may end up taking a job in santa fe though...in that case I'm looking at 4000' in change.

Hmm
Another case of Hustler needing to RTFM.

BTW mine was THE first retail sale (cuz I picked the bitch up on day 1) and there is a Mapdaddy dual MAP sensor in that biatch.

There's a "baro correction on power-on" option, but I don't remember the details. Basically, when the megasquirt powers on, it reads the manifold pressure and treats that as atmospheric. So you don't get realtime correction, but for a track day it should be fine.

Also, I bet if you have EGO correction working (which I don't yet :/ ) you'd be fine for just normal driving.
