All sorted thanks to Adam and jase brown, turns out there was coil interference on the 12v feed so isolated that and had a much crisper trigger signal, re checked timing on pressure transducer and timing was off sorted that and she fired up straight away. Much appreciate the help from the link team it's good to get these small problems sorted, forever learning Thanks pat

So severe interference or something along those lines

That's the trigger scope previously asked for

Sorted

ok so ive done a scope and the triggers seem good so my next thought is that its a wiring issue ive wired the injectors and coils the same so they are inj1 - 1&5 inj2 - 4&3 inj3 - 2&6 the coils are the same order and the firing order is 142536 would this configurationbe correct ? as for air gap yes they are all factory setups

thanks for the fast reply i will try scope this weekend as for air gap youre meaning the distance between the sensor and the trigger node on the cam gear ? as that is factory distance

hi team so its been a while since I've been playing engine tuner but I'm back to it and I'm having trouble with getting rpm, both triggers are arming crank has 3 teeth and cam has 1, the cam one is about half in between 2 of the crank teeth both sensors are hall sensors. ill crank and get around 200-300 rpm then ill crank again and get nothing, when i get it started and timed it runs well, Then i turn off and try to start again with no firing or just the odd back fire. below attached is the tune and a log file hopefully there's something I've done wrong that you can see otherwise i will have to have and auto electrician look a it up here in Hamilton. thanks again Pat j30a4 300zx map.pcl Log 6-11-21 7;38;41 pm.llg Log 10-11-21 5;11;52 pm.llg

awesome that seems to have sorted it i could only turn over by hand as the starter battery is flat trigger 1 is triggering but trigger 2 isnt i will check wiring on it and go from there bloody ledgin mate thanks

both say no and not green have just checked wiring and there's 12v to the sensors. j30a4.pcl

ok so I've don 3 evenly spaced teeth on the crank and one pretty close to the middle of a crank tooth cycle on the cam. I've set up up for multi tooth on the crank but I'm not getting a crank rpm signal any ideas I'm getting power to the sensors

So would I be right in saying set it to TDC and have a tooth on the crank wheel reading there and 3 spaced including that one, then one at TDC reading on the cam ? Or will it not matter

24-1-1 and yes 6.20 tried downloading and reinstalling tonight with same problems ill try another computer tomorrow

also running in to the same problems i have a series 1 g4 atom trying to run a j30a4 but cannot get communication from crank trigger, is there a way of getting the j30a4 trigger on my ecu? also cant run the g4x software on my computer keeps saying a file is missing once installed. thanks pat
