Data Data! Invaluable!
I was watching chassis torque and four link. Interesting.
On ours the dump X 2 or one did nothing. But we are a measly NA motor! HMMMM

Thanks for that JR
and Larry.

BIGGEST THING I caught was shift on both time and rpm.Mine is setup to do that using delay and rpm switch. would be nice iof could do with one piece.Lass wiring less pieces to screw up.

I thought Rusty said Grid could do that?

Biggest thing I caught was gapping plugs at .012.. That's almost closed compared to my .026..lol

Guess I'm just a little guy only running 12-15 lb boost, with a grid.. lol

He did say that. I was referencing that I had it set up to do just that but doing so differently. Grid is on wish list but not happening soon.

Did catch .012 plug gap also but had found that with mag long time ago,well close. Just figured a mag deal.
