Thanks heaps. The V6 Ecotec has a cam sensor (i.e. sync) in addition to the crank sensors, so I should still be able to retain Multi-point Group (because I'm using a V44 on a 6cyl)?

Thanks Simon, I've attached relevant wiring diagrams to help clear things up. Any further help will be appreciated. Cheers, Chris

Similarly, the factory speedo signal is an intercept of the cable that runs from engine ECU to VSS. The engine ECU supplies 5V to the hall sensor VSS (via the aforementioned cable) and the ecu internally monitors when the 5V is grounded by the VSS. Therefore, I take it that the speedo runs off a 0-5V square wave signal. I'm assuming the Vipec speedo aux out is 0-12V square wave signal? If so, does this signal need to be reduced to 0-5V? What is the best way of doing this? (Car in question is a 6G74 engined Mirage w/ the tacho instrument cluster from a 1.8L engined Lancer. Wiring diagrams are being done ahead of time as the parts procurement process will take a while.) Thanks again, Chris

Hi guys, Going to put a Vipec V44 on a V6 Ecotec tow vehicle that is in the process of being turbocharged for a bit more torque/power. I've put Vipecs on Ecotecs in the past and just used Falcon coils and Camry ignitors but this time I would really like to keep the OEM ignition system. A quick bit of reading suggests that the OEM ignition system consists of a 'DFI module' that has 2 crank signal inputs and combines these into 1 regular square wave crank signal output to the engine ecu. From there the engine ecu determines timing and sends a single timing signal back to the DFI module. The DFI module then acts as a electronic distributor and uses the timing signal to ground either of the 3 transistors for the 3 wasted spark coils according to the firing order. So, has anybody scoped the timing signal from engine ecu to DFI module (my cheap and nasty scope died)? Is the Vipec capable of replicating this signal? Cheers, Chris

Hi guys Not super clued up with electronics. How do I drive a 0-5V square wave tacho w/ 0-12V square wave Vipec tacho aux out? A quick Google search shows a couple of different circuits (e.g. voltage divider) that may do the job but I would like to hear Vipec's preferred method or from those who have successfully modded the signal in the past. Cheers, Chris
