The K-Pro Thread

[timot_one]

I'm not sure who did the JRSC tune, but I know it was in an EP3 that made 325 whp with the same motor set up I have.  I haven't had that problem with my car though and my threshold is set to 87 kpa.

Anyone ever have a problem with their car passing 4000rpm w/ Kpro? I had this problem before when my car was N/A but when I disabled the VTC on Kpro, everything was fine and went passed 4000. Im currently running a turbo setup with Cham's Jumper Harness and now I seem to have run into the same problem. I went to take it to Church Automotive to see if Daniel, the guy that will do my dyno could figure out the problem. What he did was datalog to see if all the sensors were workin and found that when Kpro gave me P1259 Vtec Oil Pressure Switch Malfunction code, that the CAM and CAMCMD angles went to 0 degrees. He cleared the error code, revved the car passed 4000rpm and the Cam angles went to where they should be reading. 10sec later, code comes on again, Cam angles go back to 0, Rpm drops and bounce off 4000. If any of you have had this problem or know of this, Please let me know if you guys can help a brotha out. Ive been wanting to dyno this beast for a couple weeks now, but if the problem keeps persisting then Im just gonna have to take everything out. Also, How do you get the A/C to blow cold air again. I know I have to wire up a switch but to what? dying with this hot weather comin in. Please, any help will be greatly appreciated. Thank you

I had a similar problem a long time ago with my old motor and  it wouldn't rev past 6000 rpm, but when I switched to a different map it was resolved.  I also had an issue with my vtec solenoid a while ago too.  I'd try replacing the pressure switch on your vtec solenoid.  I have a few lying around if you need one.  It may take me a while to find them since I just moved all my stuff about 900 miles and I'm still unpacking.

I actually just ordered the K-tuned harness so I gotta wait til next week when it comes in. When should the pressure switch be changed out? I have about 120k miles on the car.

Replace as necessary. Those things aren't mileage specific.

I have a question, is the only reason we have to use a dual ecu harness, or Tims setup for Kpro is because the cluster would not work?

I ask because I plan to swap in a k24a2, now would it be easier to just swap the clusters and or use the tsx harness in conjuntion with a setup like that? The dimensions on the clusters would be close if not the same I would think. I'm planning on picking up the motor out of a rear wrecked tsx from a local auto yard. Motor sounds great and the car drives well minus being smashed in the rear (from the videos anyways.) So I guess my question is should I grab the harness, cluster, and ecu while i'm at it?

[timot_one]

That stuff won't really make a difference. You can't KPro a TSX ECU. Another issue is that the TSX has a DBW TB.

Honestly, I'd grab the motor and the harness. I don't think you'll be able to use the cluster and ECU for anything though.

[Icebox]

even the harness will be useless, you will need the engine harness, dash harness, gauges, kpro'ed ecu and throttle body from a rsx-s.

or you could just buy my honda that has all that work done and some more for what you would end up spending to have all that done.
