Hey Guys I need some help. I have been having some trouble with kpro. At random times (no common factor as i can see) kpro will just go into Offline mode. I can unplug the usb cable and plug it back in and theres no problem. I thought maybe it was my computer. However, I tried it on 3 other computers and it does the same thing. One thing I have noiced is that it does generally during high load during my street tunes. Just curious as to what could cause this

the same problem could occured on some cars with the good plugs on

Datalogging disconnects are caused by (in order):

- wrong spark plugs
- engine swap harnesses
- bad / missing grounds
- damaged engine bay wiring from a turbocharger
- scotch locks / butt connectors / t connectors / mickey mouse ecu wiring

See the first part of this page http://www.hondata.com/techk20swapgrounds.html about checking ground current flows.

I have also noticed a trend of this happening when you have to many windows open in kpro ex. display, sensors, parameters. Try closing all windows within kpro and doing a datalog. Also have you windows task manager open and see if your system resource is maxing out during the datalog.

Well I bought some ferrite cores to put around the usb cable to see if that helps. Also I have ordered a set of NGK spark plugs but I don't want to use them till I go to the dyno. I also have gone back and checked all my grounds. I will let you guys know what i find out.

I will check the system resources however i seriously doubt thats the issues cause i have a intel quad core extreme processor w/ 4 gb of ram. But I will check it out next time I do a datalog as well.

Thanks again guys

Adding ferrite cores usually helps, but remember that this will not fix the root cause.

I agree. I know the spark plugs are prob the problem, however I figure the cores will solve the problem for now and will help provide further protection when I do have the correct plugs in. Thanks again for your help and for such a good product i love kpro.

Change the plugs first...especially if you know they are the incorrect plugs to begin with.

I have a set of ngks I am using bosch platnium. However I don't want to burn out these ngks so I am saving them till I go to the dyno. Thats why I don't put them in.
