Thinking about picking up an AEM EMS. I hear they like to destroy stock honda ignitors or coils, forget which. Is that true?

 

neither as long as the proper dwell settings are used.

although, when u throw the MSD into the mix, the ignitors and built in AEM EMS ignitors have been known to fail. but, when u throw an MSD onto a stock ecu u will get ignitor failures too.

seems to be a hit and miss, my digital 6 and hondata'd ecu never killed an ignitor

 

I believe the msd and the aem ems use different frequency's. I blew my coil driver in the ems and went through 2 ignitors. I then realized it was the msd box. I'm running the stock ignition system with the aem ems now with no problems.

 

I've run several MSD boxes directly from the AEM bypassing the ignitors as well as multiple stock ignition setups without issue. I think some of the older boxes had too much coil dwell in the base maps.

 

10-3000. You hit that on the money!

 

10-3000 what about it?

 

Just bypass the ignitor. Use a digital msd box and proper coil, and just wire the white wire on the msd to the coil#1 output from the AEM box. Set coil dwell to "All CDI Systems", and your set. If you are using a T1 cam trigger kit make sure you use the updated coil dwell factor and dwell max settings specified in the instructions or you'll have misfiring above 7.5k+.

 

thanks jeff. how ya been? long time no see... ahh the married LIFE!!!

 

Everything is good, just busy around the shop like usual.
