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.

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.

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

Hey everyone
I havent been on here in awhile. I was wondering if anyone has or knows someone who has a base map or calibration for a turbo setup they can let me use, those of you with Kpro. I have an 05 Accord with K24A4, stock internals. Ill be putting these parts on my car sometime in February and am in need of a basic tune to get me to a DYNO shop. Most likely Bisimoto. Heres a list of the parts that ill be putting.

-Hondata Kpro 02 -04 RSX-S
-Cham custom Split Harness
-750cc RC Injectors
-HKS GT2835/GT3071 w/ T3 turbine
-Walbro 255lph fuel pump

-Tial 38mm wastgate
-Godspeed same side in/out FMIC
-Custom IC piping HKS BOV
-Vibrant 3" Exhaust with Ultraquiet resonator
-04 TSX intake Manifold
-Hondata boost solenoid

Please, any help will be appreciated. Thanks!

Right here Ryan!  There's about 4 products that I want to get from them.  BTW, I love the UR "Show Girl"!

Agreed with Tim on them products and yeah, them "How it works" illustrations make me want them even more Ryan. Im pretty down for a group buy if it ever come down to it

So what is wrong with the car when you try to drive it? It doesn't go past 3k rpms? I can't remember.

did you try to clear the code in kpro?
are you low on oil or running thicker oil than 5w20?

My oil level is fine and I always stick with 5w 20
Here are the problems:
-Engine cranks rough when starting or shutting it off.
-Wont allow me to pass 3800rpm
-Ive tried to clear the code on my Kpro, but keeps popping up
-VSS stays at a certain MPH when datalogging (first datalog stayed at 158MPH and 48mph another time.)
-Before I switched back to the Stock ECU, I had problems getting my car to crank. Sometimes, i would have to wait a bit then try to start it again. Didnt feel like the battery was dead cuz it still cranked.

I was having problems with my Hondata and it wouldnt read A/F or datalog. well I got my Ecu repaired and now Im comin up with a Vtec oil switch malfunction error code. I tried to switch the negative and positive wires on the VTC, but still no luck. Have any of you encountered this before and if so, is there any way to get it taken care of? Thanks

Trace the VTec pressure switch wire, sounds like it is not hooked up. the VTPS is normally closed to ground and opens when the VT solinoid opens and sends oil pressure to the VT system.

I have the wires two wires from the harness hooked up to a connector to the vtc oil pressure valve that I bought at Acura.

Alright. So last week, before I changed back to my stock ecu, I used my multimeter to see if there was currency flowing and it was confirmed there was currency flowing thru the vtc wires to the actual vtc oil pressure switch on the side of the engine. Im really planning on giving up, but I'd rather not. Would any of you be able to help me out on this one? Thanks

Well. Both the CEL on my stock gauge and the external one are on. Its reading nothing on K-pro, no codes, no datalog. only thing I think I can do is upload maps to the Kpro. Im thinking the ECU is the problem. If its cool timot_one, I can try uploading a better map if you have one and Ill let you know if theres a difference from the map I uploaded. If it still cuts off at 4000rpm, then im sure its the ECU and ill just have to get it repaired on Ebay. Im sure I should see a difference if its not the ECU. Lemme know as soon as you can. Thanks

The CEL is always on. Im only using the stock calibration thats on K-pro for the Accord. I didnt touch any of the settings.

i had gotten everything hooked up this weekend and double checked the everything before i plugged in the ECU. Turned on the car, but when i tried datalogging, it wasnt reading anything. I drove it a bit to see if it drove normally, but when i punching the throttle it would keep itself from going over 4000rpm. im thinking its the ECU. I got the  Kpro'd ECU used on CRSX forum so I was thinking of getting it repaired on Ebay if i have to beacause theres a seller that does repairs. Have any suggestions guys?

im using the RSX-S sensor. nope, i was just gonna run off the stock calibration for the Accord thats already on the K-manager.

hey guys, I just hooked up everything i needed to hook up on the car. I was wondering if i need to do anything with the settings before starting it up? I had to go with the soldering pathway because i received the wrong connector. I read about changing the voltage for the o2 sensor, but i dunno if it was just for the AEM one. please, Im thinking of getting the car running tonight so i can use it in the morning so all help is appreciated. Thanks!

lol. cool. Thanks for the input you guys. Ill take your words on the RSX sensor.

I have the caspers adapter harness for the rsx 02 if you decide to go that route. This way you wont have to worry about sodering just plug and play. Brand new never opened let me know.

I really dont mind the soldering but ill let you know if i decide to go that route. Anyone know if the TSX Sensor is the same as the RSX sensor? I heard it might be the same, but with a female connector like the Accord. Any other suggestions?
