Steve Bull Posted May 12, 2015 Report Share Posted May 12, 2015 I had set the ecu up to run 8 coil on plug using all 8 of the inginition channels. However, i need more Aux outputs so i need to go to wasted spark to free up 4 Aux channels. Can one ignition channel cope with two coil on plugs. Quote Link to comment Share on other sites More sharing options...
Brad Burnett Posted May 12, 2015 Report Share Posted May 12, 2015 You should be fine to use one ignition channel to drive 2 channels of an ignitor or 2 internal ignitor coils. Quote Link to comment Share on other sites More sharing options...
Steve Bull Posted May 12, 2015 Author Report Share Posted May 12, 2015 Thanks for that, it will free up 4 outputs. Â One other thing on the 1uzfe (vvti) which sensors require 5 volt and which require 8 volts from the ECU. Â Quote Link to comment Share on other sites More sharing options...
Simon Posted May 13, 2015 Report Share Posted May 13, 2015 The TPS will need 5V The crank / cam sensors are all reluctor so only have an earth and signal. Quote Link to comment Share on other sites More sharing options...
