Hey guys,

Some pre-specs on the car:
b18b1 with GReddy 18g turbo kit, with blue box fuel management.

Well yesterday, I started my car in 0 degree weather, and did a bit of an odd idle for a few seconds, then went back to a 1.9k higher idle to warm up. The CEL lit up, and has since been on. It has also since been driving fine (as far as I can tell) and starting fine. I haven't been hitting boost at all. Went to auto parts store and checked the code to be P0108 MAP high input.

My question is-
Because of it lighting up from a cold start, does that hint to anything particular going wrong?
Once the CEL is lit up, will it stay lit up even if the issue resolves itself?
Since it is OBD2 ECU, will it always keep popping even with the GReddy blue box installed?
Anything you guys suggest I look at?

Your thoughts are much appreciated.

 

Anyone familiar with this code?

 

Map sensor?
