MSPNP2 base map error? Paging DIY!
So I've been really struggling with cold start issues on a few MS2PNPs I've tuned recently. One for a 90-93 with a MSM swap, a 99, and a 94. The 94 is the only one with the older V1.2 board.
I just found out about 10 minutes ago that all the base maps, under "Startup/idle", and "idle control", valve mode is set to "inverted, 100%=off".
Which is backwards from all the tunings I've done on MS3s and MSpros. I've been wasting a lot of time tuning backwards, only to find out about this little issue.
Was this on purpose, and if so, why?! Or just a mistake overlooked in the base map?

So when I'm tuning and want the valve to open more during cranking, do I wanna take duty cycle away, or add it? Aka, if it's not starting well at 50%, do I want to try 55% or 45%.
