So i just recently purchased aem ems v2 ecu and tuned my ap1 s2k and she runs good sometimes and then sometimes it just doesnt feel as strong an also when i try to start it up it takes 2-3 cranks an sometimes she wont even start up please help me.....

 

Which problem? Not feeling as strong/not starting. Did a tuner tune it or did you do it personally? The long start is an AEM trait. My car has an AEM and it starts fairly well, but I've never had any issues not starting.

 

it doesn't feel as strong at times and my vtec was set to kick in at 5k rpms but sometimes i wont hear it till about 7k rpms......and as far as the long start is it anything i can do to get it to start up fairly quicker? i read some stuff about adjusting the cold start callerbrations but idk.....and yes i got my tuned by a tuner.....
