The K-Pro Thread

[Icebox]

if the immobilizer isn't disabled and you haven't had the ecu a key matched then the car shouldn't even start.

2 questions:

1. is the civic si primary o2 sensor wide band? i think if we use that, we wont need to solder the ends, i think its a female connector unlike the male connector on the rsx-s

2. with the kpro setup, is the immobilizer disabled?


thanks!

1. It is "Wide Range" not "Wide Band" , google to learn the difference, but both give fairly accurate reading of actual AFR

2. KPro can operate both ways but you will need a dealership or HDS to program in your keys.....

Tim does your Kpro read the correct mph when you datalog?

[timot_one]

I remember when first running the SC, the VSS read a constant 144 mph.  I went back and reviewed a few datalogs and they have the correct MPH.

hmm... another sensor i need to hook up... well, at least figuring it out is fun!

[asnstyle22]

hrm... ok so anyone with chams kpro harness having issue with the rpm not passing about 6k?

also have the problem with the vss reading constant, is there something i need to change for that?

oh for the hvac, mine is kinda funky, when i have the ac on, the rpms would plunge every so often to like 300, is that normal?

thanks for any help.

I've had issues with the rpm's not passing 6k, but that was the base map, not the kpro harness.  The VSS reads constant on mine also, but I haven't really changed things around to see if I can get it to work.  My HVAC is also a bit funky like yours, but it doesn't drop to 300 rpms.  It does drop when the compressor clutch kicks in though.

[asnstyle22]

hrm... what you mean its the base map? i tried to get the car tuned and the tuner said the car wont go past 6k even if he sets the fuel cut @ like 10k.

so does that mean like he needs to tune from scratch? (not sure if thats possible) and he said he started with the tsx basemap.

[timot_one]

 had the same problems with my old motor when I put the SC on.  We tried switching ECU's, switching the KPro harness, and still had the same problem.  We used a different base map to tune with, and it went past 6k.  Is this a n/a tune?  What bolt ons do you have?  I may have a base map I can send you to start with.

[asnstyle22]

its a N/A tune... but its built k20/k24 engine.... hrm... so what basemap did you use to start with for the tune? maybe i can just use that map and adjust all the parameters to what its at now and see if the engine will go past 6k. (heh i spent over 1g on tuning and i dont wanna dish out more money just to see if it might work =P)

and for your tune... did you set the vss to constant?

and you said that your obd2 reader can tell what the real temp of the coolant is? like an accurate reading? shouldnt the kpro also have an accurate reading of the ECT?

plus does your CEL from the harness actually work? ive hooked up the kpro to a laptop and it would show a error but the light doesnt light up. i dont remember what the error is from exactly but it occurs when my car cranks a little longer than usual to start for some odd ball reason and at the same time, the car doesnt rev past 4k when that happens... when i turn the car off and on, the car runs normal again but the error is still logged, but no light. (kinda redundant but hope it makes sense)

thanks very much for your input

This tune is for a K24A4, n/a.  I don't know what basemap they started with, but the tune I was using raised my redline to about 7800.  I don't remember what the VSS was set to on that tune though.  My OBDII gauge reads from kpro, so the ECT reading is the same on my gauge as it is when I monitor it with kpro.  My CEL on the harness works flawlessly.  I'm not sure what the problem you're having is, but it could be the tune, or it could be the ECU.  One thing that I've done in the past when I have weird problems, is erase the ECU and re-upload the tune.  When I had the problem with my crank position sensor, the code came back after I replaced it.  I erased and re-uploaded my tune, and it worked fine.

Here were a few problems with my AC:
The pinout for the FANC was not connected. E12 on the accord harness. This allowed the stock computer to turn on the fan when the AC is on.

Your idle is low because your stock ecu doesn't know that it is under load when the AC is on. You need to connect B13 on the stock ecu. This is what the stock ecu uses to determine the engine load. This will help with idle if you have your stock computer controlling your idle. I recommend this if you really care how your car behaves with AC/Idle.
     If you want to let the stock ecu control idle disconnect the IACV pin from the Hondata ECU (A12) and pin that into the stock ecu (A12). Then in your Kmanager under the idle tab, disable the idle control valve.

I've had the same problem with the Engine coolant temp. Mine reads really low because the signal is split amongst 3 sensors. This has caused my auto tranny to go into limp mode and sometimes prevents me from going into 5th. You might want to go on to Kmanager and under the protections tab disable the overheating protection. The main one is the one about set rev limit to 4k rpms when overheat. You might also wanna check what you set the fan temps at because this can fool your kpro into thinking its overheating and applying the rev limit if you had enabled it.

let me know if you need help. Maybe we should make a sticky letting people know what things to connect or trouble shooting for the kpro and the accord.

[timot_one]

That's a fantastic idea Ryan.

Just FWIW, as of a few months ago, Hondata no longer offers KPro for the TSX
