K-Pro in Element

HONDA GHANDI · Post by **HONDA GHANDI** » Thu Jan 18, 2007 6:18 pm

Just as an FYI I got the k-pro installed in our project Honda Element today. After a few minor installation bugs it works fine. I found out hte RSX ECU does not fit in the slot where the stock ECU comes out on the E. SO I modified the board slightly, modified the bracket slightly and put the RSX ECU and K-Pro in the Element ECU case and isntalled it back in the vehicle where it came from orig. I will have pics up of the install and board mods tomorrow. I tuned it for about an hour on the TSX map and picked up 4-5 whp. A whopping 135 so far. More tuning on E-85 and a turbo kit are on the way in the next few weeks so check back for updates.

are you using the Element o2?

Right now it is in open loop mode with the stock sensor. I am currently fabricating turbo components for it. It will go back together with a RSX-S sensor in it.

Well after a year of speculation and decision making, we finally decided to go forth with the turbo project for the shop truck, Honda Element. We initially decided that we would supercharge the already stout K24. But at Sema this year it was brought to our attention at the Hondata seminar that the K-Pro could be modified to use in the Element. After bugging them for a year and a half our dreams finally came true. So this is the first installment of our project. We plan to have the turbo kit finished and installed and ready to race by March 17th. The NOPI season opener at Phoenix raceway. (That's only 6 weeks folks!)

So here it goes. The parts required to install a K-Pro on an Element:
1. RSX-S ECU 02-04
2. Hondata Adapter harness
3. Hondata K-Pro
4. RSX-S wideband oxygen sensor

At first I thought the K-Pro install would be as easy as an RSX or EP3. I was not so lucky. The ECU sizes are slightly different, as well as the bracketry that mounts them in the dash. Here is a quick pic of the RSX-S ECU required to run the E with a K-pro next to the stock Element ECU.
As you can see the rsx ecu is slightly shorter in size and has different mounting points. These mounting tabs are the reason for me modifying the stock Element case to accept the rsx ecu board and K-Pro. The RSX ECU wont fit into the slot where the stock ecu came out of on the Element.

Now, more issues. The stock Element case is longer and has different mounting spots to mount to the case itself. The RSX holes DO NOT line up.

The screw that mounts the K-Pro to the board is the only hole that is correct. So some things are going ok at this point. I elongated two of the holes to make it so that I could screw the board to the case securely.

But do NOT elongate and screw down the hole in this pic. The screw will make contact with a power tab section of the board and short it to the case. This can cause serious board damage and possibly engine/K-Pro damage!! As you can see in the pic, the metal power tab part of the board is sitting right where a screw would go to the left of the heat sink.

Now that I have that all taken care of, I move on to the USB port notch. Easy enough right? Wrong. There is a steel bracket in the dash that holds the ECU. It will need to be removed and notched as well as the case. The USB port faces forward directly into the firewall so it will need to be installed as the ECU is installed and left in there. Your tuner will love you for this step, trust me. Here are a few pics of the ECU case, with and without notch. And the bracket installed and notched.

Now the ECU part is done, install it into the dash as you removed it, with out course making sure that the USB cable is attached, and routed so that it wont be pinched or kinked. Install the adapter harness carefully and make sure that it is secured. It takes some work to make it clear the glove box but it can be done.

Install the RSX-S wideband oxygen sensor (primary) and you are ready to tune. I installed the TSX basemap into mine and the car fired right up. Next stop on this little journey is the manifold construction and installation. We have decided on a tubular manifold, T3-T04E .57 trim turbo with a .63 exhaust housing. Air to water inter-cooler (for lack of room for a decent front mount) and 850CC injectors. We plan on revisiting the tune this season with some E-85 supplements as the project progresses.

Thanks and stay tuned!

Very impressive, too bad you had to use such a bfugly vehicle like an Element. Good luck with it.

I didnt "Have" to use the Element. I have three other cars. I just thought it would be something fun and different. There is a pretty big Element community, and there is not much in the way of performance for them.

just wondering..i thought hondata said that even tho you use 05 kpro with harness on the element or the accord. the cluster and climate control will not work. so did you fix this yourself? or just run it without those? i'm confuse now. if somehow the speedo and what not work, does this mean it will work on the accord the same way?

The Accord I am not sure about. The Element problems have been fixed by Hondata. www.hondata.com has been updated and shows what ECUs can be used.

Update: I am off to Phoenix today to run the Hellement in the desert at the NOPI event this weekend. Wish me luck guys. Hope to see some of you there. COme by and say hi, Im the bald one standing next to the rediculously fast Honda Element. ;)

Good news! The Hellement ran a 13.88 @ 102 mph. Had some detonation issues in the heat but got those fixed and ended up winning the Bracket 14 class for the weekend. Thanks Hondata for your help in this win!

Hahaha... seriously need to post some videos of the element surprising cars on the street. It will become viral. Youtube it ;).

Year end update. Final results after the 3 inch exhuast and tein suspension, the best time of the year was a 13.3@109mph. Ended up with a points championship this year as well as a NOPI win and burnout contest win. The Element has turned out to be quite the race car believe it or not.
