Default AEM EMS V2

hey guys,
thinking of maybe possibly getting the V2 of the AEM EMS.
quick question though.
does it still have start up problems like the first version did?

I haven't used a v2 ems, but the startup issue is very easy to fix. there are 2 resistors, one for the cam and one for the crank sensor. If the car is slow to start swap them out for a higher value resistor and the car will start up just like stock.

This is due to the very large variance of the cam/crank sensors that honda uses. some work perfect some dont.

i used 4.7k ohm resistors.

hmmm..intresting.
resistors....if i remember correctly. in guitar amplifires if you dont discharge the resistors properly one could die. if i;m thinking of the right part.
I'm guessing the same is true for a car's resistor?
or is that the caps?

anyways.
when changing the resistors do you have to solder it on?
or is it something you just switch out?

anyone else on this forum got some infos?

thats capacitors, and only at a high value will they hurt you.. nothing inside the ecu will hurt you.

they have to de-soldered to be replaced.

the 2nd video is pretty close to how my S was after i "fixed" the gen1 box.

The car started at least as fast was with the stock ecu. I'd get a video, but my car is in pieces getting a new motor
