My s2k is completely stock other than cold air intake / exhaust. I want to get a E85 tune; to get a little more power out of the car so with that being said. What are the best EMS systems? I've read about the AEM EMS SERIES 2 and I like what I see, you can pretty much control your motor in every aspect. I would like to get this EMS for now but also in the future if I decide to turbo my S! Feedback/ or advice is welcome!

 

there's aem and haltech. talk to your tuner and ask them which ecu they prefer to tune and go with that.

 

Is there a specific series of haltech for the s2000. Like platinum sport 1000 or platinum sport 2000, I don't know to much on haltech!

 

they used to make a patch harness for use with their sport 1000 ecu. they now make a pro plug in ecu which is a direct replacement for the factory ecu.

 

Yeah I seen the pro plug in after searching through the website more. How does the Haltech pro plug in compare to the AEM EMS SERIES 2?
