Thanks, Lance! While we're on the subject, is there any section of these message boards, or anywhere else for that matter, that refers to the developments which use the 3.76+ firmware? It might be helpful to know, since I can keep in mind that the discussions there probably won't pertain to my ...

I've looked all around the message boards and in the megamanual, but I seem to be getting different results in regards to what exactly the most recent firmware version is for MS2 v3. On this message board, it says 2.905, which agrees with here: http://www.megamanual.com/ms2/code.htm

But when I go ...

Success!! I moved the GM sensor to the location next to the water neck, and relocated the Autometer sensor to the cylinder head. There's still a little bit of difference, but we're talking maybe 5 degrees or so. Thanks to everyone who chimed in and helped solve this annoying little problem!!

EDIT ...

Actually, the Autometer gauge is using a bushing. But, A) it came with a bushing from the factory, and B) the actual sensor is 1/8 NPT (seriously, Autometer? 1/8 NPT?? Where are you expecting me to install it??)

Well, now this comment has me wondering if the ports at the back of the intake are just no good to use. As far as I know, those rear ports are not flowing ports. In other words, the sensor is ...

Unfortunately, my Autometer gauge only goes down to 100 F, and the daily temps around here (Detroit) haven't been hot enough to register on it (not complaining, mind you, lol). The MS does, however, report a fairly approximate ambient temp. My main concern is that, if the temps really are that much ...

I'm actually considering moving the front sensor (next to the water neck) back to the other rear coolant port. The intake has an identical port to the one that the GM sensor is currently installed in, but on the opposite cylinder head. Unfortunately, the rear ports are a different sized diameter ...

Hi all, I've spent countless hours/weeks/days/months building and installing my MS-II v3 into my 68 Camaro with a mildly built 350. Things seem to be coming along nicely, except for the coolant sensor. I bought the MS-II as a DIY kit from DIYAutoTune, and they included a GM coolant sensor. I have an ...
