Jurgen Biggelaar Posted December 10, 2009 Report Share Posted December 10, 2009 Hi Brad. Assuming your tacho on the dash only needs a 'low level' input meaning it uses a very small voltage, it will be no problem at all. Low level is most likely the case for you and most common by the standards in a Japanese car. By trying it you cannot harm your tacho or ECU so don't be too concerned there. Seeing as you are only using 1 of the 3 ignition channels available with the distributed set up, a feature in the firmware will allow you to set ignition channel '3' as a tacho or a shift light. The ECU IG3 wire is Blue/White and is the 4th pin along to the left of the tag on the BIG plug. This will be wired to your tacho input wire (will only be one to this in the dash), and using a hand controller go to 'Configuration' and set IG3=Tacho. Alternatively if you have the SerialLink to connect to the ECU with your PC, this setting is found on the main config screen labeled 'IGN3 Mode'. See here for the manuals available - http://www.linkecu.com/support/documentation/g1-engine-management-documentation And this will download the correct PCLink software to program the ECU - http://www.linkecu.com/support/downloads/pclink-download/PCLinkV25 Jurgen Quote Link to comment Share on other sites More sharing options...
