I am running a sr20 dizzy and only using the sync side of it. any help would be good thanks in advance the tooth count in trig 1 is 12 now not 24 Quote Link to comment Share on other sites More sharing options...
Simon Posted October 8, 2017 Report Share Posted October 8, 2017 Have you changed the wheel in the distributor to have only a single slot for the Sync? Quote Link to comment Share on other sites More sharing options...
simonjob Posted October 9, 2017 Author Report Share Posted October 9, 2017 it is still the original sr20 wheel in there Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 9, 2017 Report Share Posted October 9, 2017 Unfortunately that won’t work. You will need just a single tooth on the cam. An easy option is using “aluminum foil tape” to cover up the unneeded slots. Quote Link to comment Share on other sites More sharing options...
AbbeyMS Posted October 9, 2017 Report Share Posted October 9, 2017 or just add a AEM trigger wheel to the CAS Quote Link to comment Share on other sites More sharing options...
simonjob Posted October 10, 2017 Author Report Share Posted October 10, 2017 like this? as I think that is like the one I have as the car used to have a autronic ecu in it? Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 10, 2017 Report Share Posted October 10, 2017 Yeah if it used to be autronic then it would already have a single slot sync. So your settings posted in your original post would be correct (except change tooth count to 12). You will need to set the base timing with a timing light.
