Aem vs hks

WITCH ONE IS BETTER?

AEM 4 Channel Twin Fire Ignition Module
OR
HKS Twin Power DLI



THANKS

AEM seems cheaper, as far as I know, most people use HKS.

i have hks and i like it . just ON/OFF
even with stock gap you can push it to 20+psi with no problem ,
currently i am using non projector NGK vracing with its factory gap (never checked but i think around 1mm) with approx 22 psi

For every HKS DLI I'm sure there have been 2-3 AEMs because they keep failing. If you look on the forums you'll see that the AEMs have an extremely high failure rate while the HKS has only had one or two usually because so much water got onto them that it shorted them out. I've owned and ran 3 HKS DLIs no issues currently with blowout at 28 psi and never had any problems before up to 34 psi on past cars.

HKS all the way. The AEM has a big failure rate.

My HKS died but I'd get another one again before an AEM based on all the neg reviews.

Gap your plugs down, good plugs, wires, new coils and you are good to 30psi.

This.
I've run 35psi on stock mitsu ignition, with e85. I had non projected plugs, gapped to .018"

I had mine up to 26 psi before on non-projected NGK plugs, new ignition system, and plugs gapped to .028" before I installed the HKS DLI. It was a boost spike though; otherwise, I had been running 22-24. I didn't try pushing further with a lower gap just figured it was necessary to install since I already had one sitting in the basement.
