both. getting the vr to work well with the external conditioners on ms1 was always a pain in the ass, it got a lot better with the v3 board and the ms1 chip, but something in the way ms2 looks at things always seems to highlight issues. my 940 would work great with the ms1 v3 combo, wouldn't run hardly at all with an ms2 or ms3 setup and the same pot settings. strange, annoying stuff.
sam's wagon is seasonal. he has to re-adjust the noise filters if it gets too warm or too cold out, otherwise it won't read cranking rpm's.
Thanks for the info, I'll keep an eye on it.
