hodge Posted February 6, 2006 Share Posted February 6, 2006 Anyone out there tell me what will be the best signals to connect to this harness. At present ive got:- E01 has a rpm signal direct from the unit. (pulse input) External harnesss:- Analog input 1 - Throttle position sensor analog input 2 - 12v ignition (for volt reading), or MAP sensor not sure which would be best. This is where im stuck. Ive got 2 pulse inputs and a pulse output . can any of you point me in the right directing. Cheers Hodge Link to comment Share on other sites More sharing options...
SimonB Posted February 6, 2006 Share Posted February 6, 2006 Well, I get RPM and throttle position from my Emanage. I use analog input #1 for my wideband AFR (although it's a bit crap at the moment because that signal is not linear) and the second one for intake temperature. Again not prefect because it's not linear, but it's near enough. MAP is pretty pointless as you have a boost sensor anyway, unless you haven't got a FCD in which case you can use the E01 as one. Speed is a good one for one of the pule inputs, because if you download the latest firmware for the E01 and put it on a SD card you can have speed-related boost maps. The outputs are pretty useless unless you want to use it as a FCD. Link to comment Share on other sites More sharing options...
hodge Posted February 7, 2006 Author Share Posted February 7, 2006 I dont have a fcd so the MAP would be a good idea I think. Would this be analog or pulse. What would I connect the output to to use this as a FCD and do oyu know the position on the ECU for the intake temp and speedo. Cheers for the help. Im quite new at all of this electronics stuff.

SimonB Posted February 7, 2006 Share Posted February 7, 2006 Analog for MAP, you cut the connection from the MAP sensor to the ECU, and connect the sensor side to the input and the output to the ECU side. Here's the MAP connection:- The other connections at the ECU can be found here http://mkiv.com/manual/manualtt/terminals_of_ecm/index.html Bear in mind this is from the USA, so is slightly different when it comes to MAP vs MAF but most are the same.

hodge Posted February 8, 2006 Author Share Posted February 8, 2006 Thanks for that simon youve been a great help. I might have to pester you for some settings for harness when I get it plumbed in but 1 step at a time I think. Tghanks again mate. Link to comment Share on other sites More sharing options...
