Finally did the wiring end of my COS5......

[Loudmouth LS1]

and I tested it out in the driveway on the transbrake, was at 26 without the switch on and flipped the switch and it dropped to 14, but I was asking it to drop 11 degrees, so it should've gone to 15, did I do something wrong that it's not dropping the correct amount, any help would be a appreciated, thanks!

I havent noticed any problems with the amount of timing being pulled. It has always appeared to match what I have commanded when tested in the pits pre run.
I will dig up some logs on my laptop when I get home & verify this.
