BURGESS.DJ Posted September 6, 2015 Report Share Posted September 6, 2015 (edited) Quick question is it possible to have a trimpot say connected to anvolt 2 when set up correctly calibration 0-10K ohm range in ecu for that input basically so you can use the trimpot to plug into the ecu in the pits for a trimming setting on the programmed function ie ignition timing or boost (not sure yet) and then unplug and keep that setting until next time you plug it in and change again? all without plugging into a laptop i guess by unplugging it the input signal will just go high or low depending on the pull up/down setting reason Im asking is because in the speedway class of racing the car im wiring/setting up is in it does not permit in cabin adjustment while racing even on yellow flag and my customer is not very tech savvy especially with adjustment of the ecu controlled timing or boost settings hence a dial that plugged in to trim then unplugged between races in the pits would be ideal for him obviously a dial mounted out of the cabin would work but i am just wondering if it is possible to unplug and plug in Thanks Edited September 6, 2015 by BURGESS.DJ Quote Link to comment Share on other sites More sharing options...
Dave Kriedeman Posted September 6, 2015 Report Share Posted September 6, 2015 Hi BURGESSDJ,If the trim pot where to remain attached that would work.However once removed it would no longer be a functioning input.The only way to make the change is to download the pcl file into the ecu with the appropriate changes required.Or leave the trim pot installed.RegardsDave.

Simon Posted September 7, 2015 Report Share Posted September 7, 2015 You could I guess have a number of resistors and change the resistor to suit as required.A bit like MSD do for there adjustable RPM limit CDIs Quote Link to comment Share on other sites More sharing options...
BURGESS.DJ Posted September 10, 2015 Author Report Share Posted September 10, 2015 (edited) okay that is a good idea NEXT QUESTION the vehicle has a quickcar tachometer which is fairlly common for speedway stuff these work with magneto and all sorts of electronic ignitions and is self powered by a 9v batteryhttp://www.quickcar.com/611-100-Gauge/ same model as this http://www.quickcar.com/product_images/InstructionSheets/611-099_611-100_InstructionSheet 10.pdfwill this work with link ecu ? 1 wire is for ground and the other is signal or do I possibly have to use a Pull up resistor from 12v onto the signal wire so it can see a change from 12v to the pulse how it would if it was set up on a dumb coil Thanks Edited September 10, 2015 by BURGESS.DJ Quote Link to comment Share on other sites More sharing options...
Simon Posted September 11, 2015 Report Share Posted September 11, 2015 Looking at the instructions I suspect that will work with a direct signal. But if not then the pull up will be the next step.A 1K between signal and 12V would do the trick. Quote Link to comment Share on other sites More sharing options...
