Yep that did the trick, thanks Adam. Hopefully that's everything tested and working now and I can get the car off too an experienced tuner for mapping now.

Realised I never responded to this but I resolved the issue I wasn't measuring it wrong the coil spark edge needed to be flipped. I set it to rising thinking I want to to rise to 7v when I want a spark. But it needed to be set to falling. This stopped it from holding a constant 7v and now fires the coils correctly.

I'm currently running into an Error 16: Cannot reach target 98% when trying to calibrate my E throttle. I'm running a Bosch 0280 750 036 from a VW 1.8T (mk1 TT) on my N300+ Its wired as per the attached diagram. PID Values are P 7.00 I 0.137 D 40.00 which were taken from the TT base map. Motor appears to move freely during initial calibration but just fails on the final part comparing main and sub tps. I've attached a log and my map and here's a link to a video showing what's happening. I tried swapping sub and main values on the map but it still fails at the same point. I'm assuming motor polarity is correct as the throttle plate appears to be reaching 100% initially. I've also tried 2 other spare throttle bodies and they all have the same behaviour. Any suggestions on what I have missed? r32-040622-neo-fuelvalues.pclr e throttle calibration.llg

Been a bit of a while but hopefully I have good voltage however I'm still not able to get any spark when cranking. I believe my crank and cam triggers are being read correctly as the injectors are firing. Engine loom is all new. I checked the voltage at the coils and I'm seeing the values on the 12v to coil match with the ecu reported values. The voltage on the ign signal wire appears to be a constant 7v, im not sure if my multimeter is to slow to pickup anything going on that line when cranking though. For reference I'm running R8 coils and the do fire nicely when using the test function. The only other thing I'm having issue is I'm also running e-throttle and so far calibration keeps failing. But ill come back to this issue later as I don't believe it would stop my spark from firing completely? It would just limit the RPM to 1700 if it did fire? I've attached a log from today which shows good voltage in case its of any use. r32-13322-Good Voltage.llg

Hi Adam, It does go out very briefly (talking less than a second) when you start to crank. Yes I can see RPM signal visible in PC Link when cranking when it reconnects.

Apologies for the similarity of this post with some others here but after some digging I've still been unable to resolve my issue. I'm running an RB25 in my R32 powered by a link G4+ plugin which has recently had a full engine loom made from scratch. Unfortunately I'm not getting any spark when cranking. Despite being able to get good spark from all 6 plugs using test function in the Link software. I noticed that similar issues reported the ECU dropping out and problems around the ECCS relay having low voltage, my ECU does drop connection briefly when cranking however it does reconnect quite quickly. I have tried the following as advised in other threads: -Grounding PIN 16 - This does wake my ECU up but it still drops when cranking -12v feed from battery to pin 45 - ECU also still drops out when cranking -12v feed from battery to pin 49 - ECU stays alive when cranking but still does not spark. -My ECCS relay was replaced when the new loom was built I have checked and with ignition on and have good 12v+ on 3 pins and 0v on ground as expected. Trying to rule out voltage drops else where I have also: -Added additional engine earths -Tried 2 different starter motors (2nd hand but from working cars) -Supplied 12v from battery direct to starter motor and earthed on starter mounting bolt. -Supplied 12v direct to my junction box post at the front of the fuse box with earth on engine block. Is there anything I have missed that would cause such issues when cranking?

Can anyone tell me if the Link G4+ N300 plug in requires the +12V ECCS supply on pin 109. I can see from the later G4X 300ZLink plug in pin 109 is marked with a NC. But this information isn't available on the N300+ manual. Reason for asking is I've just had a new engine loom made and fitted but it was created using the G4X pinout and want to make sure if this is missing on my G4+ it wont cause me any issues. Attached the N300+ and G4X 300ZLink pinouts from the manuals for reference.
