ozyvr4 Posted March 23, 2020 Report Share Posted March 23, 2020 I have a 1990 VR4 Galant with the VR4Link P&P ecu. I am having trouble with my speed signal. I have it set up to DI 3 ( FL wheel ) . The VR4 uses the front ABS ring for the signal. The signal is very erratic. Any help would be great . speed signal.llg Quote Link to comment Share on other sites More sharing options...
TechDave Posted March 23, 2020 Report Share Posted March 23, 2020 Looks like noise, only reaching 92 Hz, so you're not maxing out the input. I'd be surprised if this truly came from the ABS ring itself, my diagram is really old and hard to read, but it looks like the DI3 speed source is actually the cluster.

ozyvr4 Posted March 23, 2020 Author Report Share Posted March 23, 2020 I'll have to look into that. I did not know the dash cluster had a speed signal out. It uses a cable from the gearbox. Quote Link to comment Share on other sites More sharing options...
