Crispin Posted August 31, 2008 Report Share Posted August 31, 2008 2 reluctor sensors gapped at around 0.75-0.80 mm I need lower threshold values at higher rpms than at lower rpms to get correct readings. At 1000-2000 rpm it works fine with 2-2.5v threshold and filter at level 3. But in order to stable readings without misfires or trigger errors at 6000 rpm I need to lower filter to 1 and reduce threshold values to minimum, 0.2v! I tried different sensors (these ones are new), different cables everything… still the same. It seems kind of backwards? It seems I get lower voltage values at higher rpm’s… how can that be. Could switched + and – cables to the sensor make a reverse reading like that?  Any ideas? It's hard to scope the signal with the car running.

Simon Posted September 1, 2008 Report Share Posted September 1, 2008 At higher RPM the signal can sometimes drop off a bit but nothing to the extent of needing trigger levels that low. Really need to get the scope on there to look at what is coming into the ECU. Quote Link to comment Share on other sites More sharing options...
