MTX ECU vs Regular ECU

[nswsparky]

I am looking at getting the cold weater start ecu for my 07 bare model that has been converted over to a 144 track. I saw on the OEM catalogs that the MTN Lite has a different computer than all the other models. I was wondering what the difference was and would it be in my best interest to get the MTN Lite computer vs the regular computer?

only thing i can think of is its programmed for elevation maybe? shouldn't be much different cause it's tbi, but what do i know.

Speedo is programmed for 8 tooth drivers instead of 9 tooth. That's about it.

seems logical. And i have a 9 tooth anti ratchet so I don't need it.

I have same sled (shorty made into a 144"). My speedo is off for sure with the MTX drivers and 144" track I installed. Any way in the speedo set up to modify that?

My wife thinks we are flying, since it is off by like 10 mph on occassion depending on the speed we are really traveling.

What you could do is get a speedo recalibrater like the one from 12oclocks labs they work great in my jeep and they are actually marketed mostly to motorcyclists it was only like $85.
