hondata computer failure?
Posted: Sat Jun 09, 2018 3:18 pm
Dear Hondata et al,
I have an 07 lotus elise with japanese civic type r engine. The car runs fine as long as I never connect the laptop to the hondata computer. But if the laptop is connected, the Hondata seems to go bonkers! I noticed this first a week or so ago: after connecting the laptop, i took a drive and asked the laptop to record--I'm not sure it was recording because after about 1 mile, I noticed neither the speedometer nor the tach was functioning! I immediately turned around and then disconnected the laptop, even before i was sure it was connected. On the way home, i noted that the odometer was also not working (not surprising) and neither was the gas gauge. When i got back home, i immediately turned the car off, and then turned it right back on, and everything was fine!
Because i was using a new laptop with the latest kmanager (?) software, i hooked up an older laptop and refused to upgrade its software. When i took it for a ride, it did precisely the same thing, except that i stopped, disconnected the laptop, and turned car off and on right away, with the same result.
So the car is fine because, apparently, the lotus and honda computers are separately working just fine, with the Hondata computer unable to interface the two. I have copied all the numbers,... from the unit and need to know what to do next.
Thank you very much,
Don DeMeritt
