- a specific description of the problem
I just upgraded my older Kpro to the Kpro V3. Just received it from Hondata last week Friday. I've also installed the latest Kmanager version (V3.2.4) onto my laptop and installed my ECU in my car. Here is my problem, the ECU connects to the laptop with IGN ON, it reads "Online", then when I start the engine it goes "Offline". There are times when the car is running, KManager stays "online" for a few seconds then it goes "offline". I tried using another USB cable, but it's still the same. Before sending my ECU for the upgrade, it hasn't given me these online/offline problems.
-When and where you got the K-Pro
Purchased K-Pro through my friend, but sent it recently to Hondata to receive the upgrade due to my K-Pro being the older version without the datalogging feature

Thanks in advance

What spark plugs are you using?

NGK spark plugs. Not exactly sure which ones, but I had them in my car when I previously got it tuned but couldn't really tune it because it didn't have the datalogging feature.

What exactly is the part number of the spark plugs?

All K-Pros have always had the ability to datalog.

I'll get back to you on the spark plug but as for the k-pro, I didn't have the on-board datalogging feature. It was the older k-pro's in which I had to pay the $250 upgrade

NGK R5672A-9

Thanks

The NGK R5672A-9 is a 'racing non-resistor spark plug'. See viewtopic.php?f=12&t=3093

Thanks, originally I had NGK BKR7E plugs. My tuner told me to switch it to the NGK R5672A-9. Which spark plugs do you guys recommend for turbo application?

Once again, thank you.

some part numbers can be found at http://www.hondata.com/techksparkplugs.html

Thanks for all the help Spunkster and Hondata. The spark plugs where the issues. Will definitely visit and post more on this site as I got fast help and response. You may close/lock this thread as it is a done deal.
