Question.. We have an Evo 8 bottom end, evo 9 top end, evo 9 trans..

20g turbo, bunch of other goodies.. long story short, we have an AEM EMS we are using to tune the car.... when coming to a stop the car will randomly drop to around 200rpm then stall..

voltage is reading at around 11 on start up (low)..brand new alternator and battery..

any thoughts?

 

Some sort of parasitic draw, possibly a short... take the negative battery cable off and measure amps between the negative battery cable and the negative battery post...
