Hondata

Hi,
would please have a look to my datalog?
I have some questions:
- It seems that some data are missing. It is like K-Pro lost the connection with my laptop. What can be the root cause of this problem?

- There are some knoks. Are they real?

I use to datalog quite often, but it is the first time I notice these kind of problems. Nothing has changed since last time I have done datalogging.

Car = Turbocharged Civic Type R 2003 (Europe)
Engine: K20A2 (stock)
Gas: 98 RON
ECU = PRA
KPRO rel. = 1.2.3.3
USB cable: stock Hondata cable
Plugs: Stock NGK Iridium grade 7

Thanks

Yes, I would say that the ECU is picking up real knock.

Check your spark plugs - what gap are you using?

The gap of my spark plags is 0.8mm (0.031"-0.032"). Is it OK?

Is grade 7 OK for spark plugs or I should try grade 8?

The ambient air temperature was about 10 degrees Celsius higher than usual..

Any idea for the datalog lost of data?

Gap the spark plugs down a little - around 0.6mm. Heat range 8 might be better for your boost level.

Try re-gapping the spark plugs and see if that changes the datalogging problem. If that doesn't work, start to measure ground current flows between the USB ground and battery negative terminal.
