JEM Posted February 13, 2012 Share Posted February 13, 2012 Just fitted Jenveys to R300d. and need to fit new plug to TPS wiring. Battery voltage is low at the moment so can anyone confirm my readings to wires Green/Yellow 5V supply White/grey Signal Brown/Black Negative Cheers Jeremy Link to comment Share on other sites More sharing options...
Drumster Posted February 13, 2012 Share Posted February 13, 2012 Hi Jeremy, Can't help on the technical front, but sounds like you're nearly finished? Still not had a chance to drive mine since RR on 25 Jan ☹️. Hopefully tomorrow....... Link to comment Share on other sites More sharing options...
JEM Posted February 13, 2012 Author Share Posted February 13, 2012 Yes Chris need to get my 🙆🏻 in gear, I have to sort out throttle linkage, TPS and air mass. Booked in for rolling road week after next. J Link to comment Share on other sites More sharing options...
JEM Posted March 1, 2012 Author Share Posted March 1, 2012 Throttle bodies fitted, electrics sorted rolling roaded 185.7 bhp. But looks like may weekend road test is doomed, rain on its way for Saturday and Sunday. J Link to comment Share on other sites More sharing options...
Drumster Posted March 1, 2012 Share Posted March 1, 2012 Nice one Jeremy. I'm sure you'll notice the difference. Been to Brands today to get mine noise tested, an embarassingly quiet 95 at 5,250 revs Link to comment Share on other sites More sharing options...
JEM Posted March 1, 2012 Author Share Posted March 1, 2012 Cheers Chris hope throttle response has improved J Link to comment Share on other sites More sharing options...
ACJ Posted March 3, 2012 Share Posted March 3, 2012 I can't remember which colour wire does which but there is a simple method of working this out using a basic multimeter. I found this on the Emerald ECU website but generally TPS sensors all work the same, with 3 wires. The method is as follows Disconnect the TPS Sensor and work on the TPS sensor plug – not the wiring harness plug. Using a resistance meter (automotive multimeter) find the two wires which do not vary their resistance when you move the TPS spindle. These two wires are the +5v and GND - you just don't know which way round they are! To determine this connect either one of the +5v/GND pair to the remaining wire – which by default must be the signal wire. Note the resistance value you see and operate the TPS spindle. If the resistance value INCREASES as you operate the pot then the wire you are working with is the GND If the value of the resistance DECREASES as you operate the pot then the wire you are working with is the +5v If your still struggling, I will be back to my toolbox next week where I have an R300 sensor so I can then use this method to let you know what the colours do. Hope this helps Andy Link to comment Share on other sites More sharing options...
JEM Posted March 3, 2012 Author Share Posted March 3, 2012 Cheers Andy, but after charging battery I was able to use my multimeter and identify each wire. Engine is all wired up and running. Thanks for all your help, Jeremy Link to comment Share on other sites More sharing options...
Pendennis Posted March 3, 2012 Share Posted March 3, 2012 What size throttle bodies ? Link to comment Share on other sites More sharing options...
skydragon Posted March 3, 2012 Share Posted March 3, 2012 How much torque Jeremy? Link to comment Share on other sites More sharing options...
JEM Posted March 4, 2012 Author Share Posted March 4, 2012 45mm throttle bodies. 160 Chris, but have a slight problem at moment of engine surging on light load. Not good how much did yours make. Link to comment Share on other sites More sharing options...
