I have a jaguar 3.0 V6 engine from a 2000 S type in an MX5. Jaguar used an on/off VVT strategy in my engine, although I think the solenoids might be able to manage manage CVVT (later S-types did have CVVT but had different solenoids and solenoid mountings). The guy who installed my EMU Black selected a 1k pulldown resistor in the parameter tables for Ignition-secondary trigger and Ignition-Cam2. With these parameters, cam angle matches target at idle but, as RPM increases, cam angle falls below target and when VVT comes on it is many degrees behind. As an experiment, I tried 820ohm pulldown and no pulldown. 820 ohm was not quite as steady at low RPM and was slightly better than 1k at high rpm. No pulldown was above target at low rpm but was equal or slightly above target at higher RPM levels and closely matched target when VVT was on. I got trigger errors on start up with no pulldown. Please can someone suggest how to get cam angle to follow target throughout the whole rev range? I have attached maps and logs with and without pulldown, and a scope.
