Hi,
I previously owned an ‘06 SI and am interested in either the ‘06-11 or ‘12-15 Civic SI again, but I’m wondering which stand alone computers are available that are either plug-and-play or fit with a conversion harness. It looks like AEM is only available for the ‘02-05 SI.
I’m not sure if Motec has any plug-and-play ECUs for the ‘06+SI. What about Haltech or any other stand alone? I’m looking for something with more options and capability than Hondata flash pro.
Any links or info is helpful, thanks.

 

What additional features are you looking for in particular ???

 

I’m not sure specifically on the features now, I need to do more reading on the Hondata flash pro, which may be good enough.
Something that could read and tune over 30psi of boost, possibly 8 fuel injectors, full editing of the fuel and ignition tables for large fuel injectors (I’m unsure if Hondata flash pro is limited to a certain fuel injector size). Maybe boost by gear (although Hondata FlashPro might have that capability?)
It would be for a mostly drag racing application with limited or no street use, which is why I thought something more capable than flash pro would be beneficial.
I looked at Hondata’s website on Flashpro and it doesn’t explain very much about features or capability, although maybe it would be good enough for a drag racing application. The car would be using racing slicks, a roll cage, gutted, etc. but Flashpro seems advertised as a convenient thing for basic set ups.
Would it have to be a ‘02-‘05 Civic SI for the AEM EMS to be plug and play?
This is for a project car I would start in 6 months or a year, so I’m still deciding on which year of Civic to use ‘02-‘15 but would be a K series and not an engine swap into an older Civic. I wouldn’t even be the driver, a friend of mine would.

 

For a maximum effort drag car just pick whatever you like. You will end up needed to build a harness anyway. Standalones allow for a plethora of extra sensors that can be used for tuning. All will need to be wired in. Most of the Standalones offer a terminate it yourself engine harness. Really not too bad of a task.

For you application a standalone is going to have a much better feature set. If you haven't already followed Leroy with Cleetus McFarland, go have a look. Perfect example of what a standalone can do for a manual transmission drag application. They don't give away all the nuggets of gold in one episode but rather scatter that great info probably by accident across all of their videos.

 

It seems pretty involved and time consuming but something I can probably do with some hand tools.
So for the engine harness, they offer a terminate it yourself- so generally what I would do is take each sensor, then run needed wires and a wire clip to each sensor, then have those wires lead back to connect to a chassis harness(around the fender area like stock). Then the chassis harness would connect the engine harness on one side and to the ECU on the other side? So it would need two harnesses made total: the engine harness(from the sensors to the fender area), and the chassis/body harness which leads from the engine harness(in the fender area) to the ECU in the floor board?
So mainly I buy either a bunch of the same color wire, or all of the matching color wire, and a bunch of sized/shaped end clips to terminate the wires and connect them to either harness?
It seems like AEM has a plug and play EMS for the 02-05 Civic SI:? Or is it not that simple

Do you have a link to Leroy with Cleetus McFarland?

 

It looks like the 30-6030 part number AEM series 2 EMS is plug and play for the 02-05 Civic SI. That seems more like what I’m looking for.
