pault Posted August 13, 2018 Report Share Posted August 13, 2018 Hey As above I have an Xtreme fitted to a K6 or K7 GSXR 600. Im having issues getting a Trig 2 signal and rpm reading. It's a 3 wire sensor with 5v, sensor ground and signal. Setup as optical/hall and cam pulse x1. Ive tried going through all the settings such as filter level, rising/falling, pullup on/off etc. Nothing on the scope. Anyone shed any light if I'm missing something silly? Engine was running fine before hand so suggests cam sensor is good. Turn off Trig 2 and I get a rpm reading so all other settings I presume are correct. Cheers.

Greg W Posted August 13, 2018 Report Share Posted August 13, 2018 No problem on our 99 gsxr 750 , that has the later hall effect sensor like yours Quote Link to comment Share on other sites More sharing options...
pault Posted August 13, 2018 Author Report Share Posted August 13, 2018 Did you power it from 5v also Greg? I suppose you could hardly confirm the sensor pinout for me to double check, I must have it wrong. Quote Link to comment Share on other sites More sharing options...

Yep power from sensor 5v supply trigger 2 to yellow black , have used sensor gnd to black brown and trigger gnd , both work Sensor gnd was used when i had an adaptive harness to original wiring and the original uses sensor gnd current build has Link/Vipec shielded wire for trigger signal and gnd and 5v running separate to this Have Vipec and Link ECU's on the bikes Quote Link to comment Share on other sites More sharing options...
pault Posted August 13, 2018 Author Report Share Posted August 13, 2018 Hmm I wonder what my issue is then, I have it wired correctly according to that. I must double check my trig 2 from sensor to ecu header in the morning. Thanks for you're help ! Quote Link to comment Share on other sites More sharing options...
Greg W Posted August 14, 2018 Report Share Posted August 14, 2018 Tried a trigger scope ? What deg trigger offset ? Quote Link to comment Share on other sites More sharing options...
pault Posted August 20, 2018 Author Report Share Posted August 20, 2018 Turned out to be a faulty Cam Sensor, and the buggy drove in on a OEM Denso setup. Never ceases to amaze what can go wrong Bench tested new and faulty sensor to confirm, fitted the replacement, got a good signal on scope and I still could not get it to run, popping and banging etc. Couldn't figure out where I had my firing order wrong until I realised Cyl 1 isnt at the chain end of the engine like it is on a car engines. Everyday is a school day! Up and running sweet now, thanks for youre help. Quote Link to comment Share on other sites More sharing options...
