My vote is for K-Pro. I've had both an AEM EMS and K-Pro, and definitely liked the K-Pro better in all aspects. Don't waste money on piggy backs.

 

Well completely different set-up with the turbo and all, but Hondata has my vote for ease of tuning and running like OEM. The AEM EMS can do the same, but it requires more tuning ability and skill. The Hondata system is by far the best I used, but since I had an AP2 I needed a new valve cover because only the AP1's have the spot for one of the sensors. There are quite a few things to change. But very worth it!

The EMS has some quirks. Car start-up requires a few turns before the engine fires up...your tuner can reduce this if he has the skill, but it will never start as quickly as the OEM or Hondata. The temp gauge will not work unless you purchase a gadget from Modifry to correct that problem. Tip-in throttle can require a good bit of fiddling from your tuner.

 

If money is not really of the greatest concern (for those of us simply saving) and you want the product that will give the engine (turbo, FI) the smoothest run, regardless of how hard it is really, to tune, which is the one to go with.

I'm not bothered on changing sensors as sometimes aftermarket parts give more detail and allow finer tune. I'd just like to get the best system to produce power, reliably.

 

MOTEC without question.
