You cannot use a digital multimeter to establish if a ground is ok, because the resolution of the multimeter is much more than the resistance should be. You need to remove all the grounds and clean down to bare metal under the connector.

If you open up the ECU then post photos of the top and ...

I got my K-Pro in 2007 from Wangs Auto, I actually randomly would get a CEL (daughterboard communication) and after wiggling my cord behind ECU the code would go away (even if I had no laptop hooked up ...

still having issues with this, going to try my ECU in my friends car tomorrow. I did try his battery a couple months ago and it started fine and let me upload with no issues but now i tried again and it still does the same thing? the ecu ...

Try the ECU in a known working vehicle. If it works without any problems then you know there is a problem that needs to be resolved with your wiring. IF it still does not work correctly then your ECU my be damaged by the faulty wiring that is in the vehicle and you will need to correct the wiring ...

Do not plug in the USB cable until you fix this problem otherwise the ECU and/or KPro traces will be damaged from the current.

same thing happens with the USB unplugged. can I run a new ground from the pin?

I have been having an issue with the daughterboard communication light, i recently had my alternator crap out on me and replaced it. The light will go away when I plug in my laptop, then the car idles rough. I turn it off then on and it runs fine but will randomly cut out and sometimes while driving ...

i found that mine does this from time to time and its due to the usb cable thats connected to the ecu shorting out on the ecu case. if you move it, it will fix

You will have to disable the vtec pressure in the vtec parameters. No it will not casue any problems.

ok thanks for the advice, wanted to make sure.

any advice on mounting a micro switch? was trying to think of how to mount it so it can activate at the engagement point but let the pedal keep ...

so VTEC wont be effected at all? do I need to disable the Vtec oil pressure switch in kpro?

ok, what was the wire for, i know the E22 brake switch raised the idle slightly when the brakes were pressed.

could i buy the same switch used for the S200? or should i get a microswitch with a metal arm and mount it so the clutch hits it at the engagement point

Using the Power steering input may allow the car to stall at low RPM when turning the steering wheel.

ok, so should i do the vtec pressure switch, or what one would be the best one to use? already used B21 for boost control and E22 for low/high boost. should i used B9? what happens if i use the ...

also, since i already used the brake switch for my low/high boost....

i can use the power steering pressure pin or vtec pressure pin without effecting my power steering or vtec?

That was for use with the s200. You can use the OEM clutch switch from the cruise control, but it does not have an adjustable engagement point. You may find that a custom mounted micro switch works much better.

any part number or will any microswitch work? i was debating on hooking this up to ...

the hondata website used to list the link to buy the microswitch for full throttle shift from autozone didnt it? what is the part number? i was debating on buying one and trying this out

I used to have the version from about march and i just reuploaded it with the new version and now my car does not run. Do you know why this is? is there any way i can download an old version of kpro?
