Correct the harness is different.

 

Car is Finished, Converted back to a Cable Throttle and nearly every harness out of a 2005 needed to do it. Made it a K-pro and added a AIM dash. Runs nice Hope to have it on track soon. Big thanks to Mase Engineering for doing the swap. Good bye E-Throttle. I have 2 good ones (one nearly bran new) forsale along with a ton of parts off an 06.

 

You might want to call SoS and see if they want to buy the TBs. They sell big bore TBs and the 06+ TB is harder of come by. Worth a shot.

 

FWIW,
I've been running Hondata Kpro on my K series race cars since 2003. Not a single problem. Albeit, it was 2 different cars and 2 different ECU. My experience with Hondata Kpro and S300 makes me believe they make a very good quality product for an affordable pricing and ease of use.

The J's racing N1 Concepts S2000 that I drive for time attack has Motec M4 piggy back to stock ECU.

If you deal with pro racing data guy, they will all prefer motec because their familiarity of the software.

Me personally prefer Hondata and uses as much as unmodified stock wiring harness minus a few wiring that easily removed. The reason for this, is if we have wiring problem, it will be easy to get another one from any Honda dealer. While a custom one would take a while.

Honda wiring is pretty good. Although, if you change engines as often as I do, take special care to the harness as they can get damaged and broken inside.

I just got a Kpro for my 2005 AP2. Still going through wiring as I want to add a serial output so it can communicate to my MXL, and figuring out wiring to run K series wideband 02.

 

Another thing about converting DBW to cable. I had to do this on my TSX. I'm sure most of you know that a lot of Honda parts are interchangeable. The TSX close cousin is an Accord. All I need is to get the throttle cable and throttle body from an Accord. The pedals already has provision for the throttle cable. I assume the pedals on the '06 and up S2000 is the same with the earlier model.

Another tip is to remove the cruise control stuff on the throttle body by building a spacer, which I did until I found out the Accord DX don't have cruise control

 

Not sure how MASE did it but he did make the Kpro for the S2000 talk to my MXL. Works perfect so far. But it's only gone about .2 miles off the dyno.

 

This proved to be almost entirely not the case in the S2000. Intake manifold, Fuel rail, Fuel lines , ABS pump, ALL wiring harness's etc etc etc needed to be changed. I was cursing honda the whole time. It's like they reinvented the wheel between the 05 and 06.

 

I talked to Hondata. The pin out is not available for the S2K Kpro. I just have to run my own pin out.

 

Ouch. That being said, I know about wiring harness needed to be swapped. But I'm surprised the ABS pump as well. Intake manifold, fuel rails, are easy to be found, though.
