Hughesad Posted August 6, 2020 Report Share Posted August 6, 2020 I'm hoping somebody can take a look at my logs/ map and offer some advice to help get the car started. Injector duty cycle appears to be 0% which means they aren't working? Basic spec which may affect the map/ starting as below: 300zx G4+ configured for GTR Deatschwerks 1000cc injectors ,straight "bolt in" for rb26 (new) Sard FPR (new) Spitfire coil packs 2 x sard fuel pump in swirl pot , one only running at idle Radium twin entry fuel rail NZ wiring trigger kit setup as per NZ wiring instructions HKS 272 Cam shafts Internal Map sensor plumbed to rear of vacumn chamber on standard manifold ( 6 throttles) Thanks! 300ZX GTR Base Map V5.pclr Log1.llg log2.llg Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 6, 2020 Report Share Posted August 6, 2020 It is not happy about something related to the trigger. RPM shows zero the whole time. Can you do a trigger scope while cranking and attach it here. Here is a video how to do it: https://1drv.ms/v/s!AiYbYlZQuRHPmidU5V2CmTcv6t2y?e=FGqZ0I Quote Link to comment Share on other sites More sharing options...
Hughesad Posted August 6, 2020 Author Report Share Posted August 6, 2020 Thanks , I will do this tomorrow morning and upload the file. I've just remembered the car has adjustable cam pulleys, I'm assuming the pulleys being advanced retarded would affect the trigger kit ?

Adamw Posted August 6, 2020 Report Share Posted August 6, 2020 No that shouldnt effect it. Trigger scope will show us what is wrong. I would guess air gap, but there are other possiblities such as it has been pinned wrong. I have also seen some aftermarket cams with lots of end float so the gap keeps changing.

Hughesad Posted August 6, 2020 Author Report Share Posted August 6, 2020 I think you're right the trigger is pinned wrong . Picture of the actual sensor and cas pinout below. The connector on my sensor also has "rb25 neo " on it in black marker Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 7, 2020 Report Share Posted August 7, 2020 Please do the triggerscope to confirm, but I suspect that will be it. If it was a GTR plug-in that would be no problem as there is an on-board jumper to swap trig 1/2, but no such feature on the 300Z plug-in. If you do the triggerscope and notice the waveform is showing on trigger 2 and trigger 1 is just a flat line, then you will have to move that pin.

Hughesad Posted August 7, 2020 Author Report Share Posted August 7, 2020 Thanks Adam, trigger scope showed waveform on trigger 2. For some reason the files didn't save correctly for me, but image below. Quote Link to comment Share on other sites More sharing options...
