for those of you with aem ems and 650 rc injectors
just like the thread said, do you have a hard time starting the car up (especially in the morning). Just installed the aem and the injectors and also tune, now its a pain in the ass to start up the car (its not the battery, i think), but once the car is started after that everything is fine. Is that normal?

I have the newer one. when shawn (from church) email me the base map, it won't start up. I had to towed my car to his place, then we figured out that the software that come with the aem got a newer version. He had to somehow reverted it back to an older version. Yeah, the car start but after a long long long crank, and it is annoying.

How long is a long time? 5 cranks? 50?
The AEM takes a few cranks (5 say) and then should start. I've had problems with the engine cranking continually but not starting due to a slightly low battery. But then it starts first go on a roll start.
Other things you need to consider is whether or not the AEM was correctly set up for the 650s. Did they use the Battery Offset Wizard and specify 650cc RC Eng injectors? Did they do the "Change Injector Size" process after swapping injectors?
I just went from 550s to 750s and had no issues.

Before the upgrades to aem and 650 rc injectors, my car start out normal. Usually one crank will do it. Since the upgrade it takes like 6-7 cranks to start. Is that normal? should I be concern?

I have absolutely no problems staring my car cold or hot as long as i wait a few seconds after turning the key before trying to start it. Once i hear the fuel pump kick on i can start it on one crank everytime.
After you turn the key do you wait a few seconds before trying to start your car?

yes, I do wait a few seconds before trying to start the car. ANyways, just got done talking to Shawn at Church automotive, he said its a cold start function on the ECU. Once he tuned it it will be normaly again.
