Hondata

Hey all, I've got S300 and when I hit the specified speed of 50mph (which tells hondata to turn off the cooling fan) and hover around that speed, the fan relay rapidly switches on and off creating a buzz.
This guy seems to have the same problem: viewtopic.php?t=21425&sid=26dae3b1ffca0 ... 3bfea83073 ; But in my case, my VSS signal seems to be strong. I can't seem to think of why this would happen and I would like to solve the problem rather then set the limits high.

You should try the ECU in a known working vehicle and see if it has the same issue. If it doesn't then you have a wiring problem in your vehicle that needs to be resolved.
