anyone got a video of their car with AEM EMS V2 on 750cc or more? mine take 2-3 crank to start, i seen some start up after 1 crank.

if you one of them with the 1 crank start up, what your aem setting for startup?

 

I have a AEM 2 with 840cc injectors and a comptech sc and it always cranks up the first time..

 

what is your aem setting for startup? do you got a calibration file of the tune? let me take a look at it please? what kind of battery are you running by the way?

 

i was under the impression that anyone who runs an aem ems it will take a few cranks before the engine starts.

 

It depends on a proper tune to have it start on the first time. This is where AEMs are a little tricky not all tuners can get the initial crank fuel tables right.

OP even if you got someones kal file that starts on the first try it won't necessarily work with yours even if the car is the exact same setup, location (altitude) can change things enough for it to not work for you.

You need to find a compitent tuner and have your cold start fuel trims done right. You problably have no problems starting up the car if it is warmed up correct? One way is to bring it to the tuner cold and let them redo just the start up trims. Since you drove to the tuner when the start up tune was done the car was warm and the tuner just tuned it to that.

 

car will start up even if it cold or hot.. but it just doesn't do it sometime for some reason, but it will fire up if i jumper battery.

so im eliminating tune. stat sync doesn't turn on at all when this happen.
