I have saturated injectors and it does it.

Try changing the crank inject all to off. This was discussed a while ago and I think that was presented as a solution. The EMS seems to fire all of the coils when it first starts up.

about the puff - boom sound

it happens to me also , but rarely

i believe that it has nothing to do with AEM because it was also happening with
e manage blue, that i had on my previous setup

 

i havent ran into these problems yet, i have the newer 1052 box, precision 1000cc injectors, and the aem injector driver.

 

I am running RC 750 injectors, and the newer 1052u EMS (built-in injector driver, I believe). Happened today at work. 15 minute drive to work. Car sat in parking garage for 4 hours. Got the "puff" when leaving for lunch. I IMMEDIATELY turned the ignition off (after cranking to let the fuel burn off from the priming of the fuel pump... it was running for all of .5 seconds), and turned back to IGN... no puff. I emailed my local tuner to have him look into the issue when he gets around to me.
