Hondata

I am controlling the radiator fan thru Hondata which is working great. However I have the maximum vehicle speed set to 158mph because when I set it at a normal speed like 35mph, if the fan is on and I accelerate past 35mph the fan relay clicks on and off very quickly creating a "buzzing" sound while I am within 1-2mph of that speed.

This is a '91 CRX with cable driven speedo and my VSS signal is very jumpy, which I think might be the cause. Anyway to buffer the signal from the ecu so that it has time delay or something and will not cause this issue?

There is no way to buffer that. You need to resolve the issue with the speed sensor sending a jumpy signal.

Okay I will look into that. For the time being do you know if it could damage the relay running it this way?

Thanks

Its probably not good for it.
