Anyone run ems in negative degree weather? Just curious, because i may go standalone in the future, but winters up here get down to -15 or worse sometimes.

don't forget to check your "Initial Crank Pulse" table/graph. ive found this helps starting consistency quite a bit. esp the first start on a cold motor

It does work for the EVO. The factory 2-tooth crank trigger is the root of the slow starting problem for EVOs and DSMs using the EMS. Unfortunately no amount of tuning will compensate for it unless you give the EMS what it's looking for. The result is a better start than with a stock ECU.
