KevR32GTR Posted June 1, 2020 Report Share Posted June 1, 2020 I recently installed the PRP trigger kit on my R32 GTR, RB26. I am having issues getting the car to start. A few things to note. It is a built RB26, PNP G4+ ECU, VR38 coil pack. I wired in the Trigger kit as explained on the PRP site, and i get signal on both trigger 1 and trigger 2. I am not getting any trigger error counts. one thing i noticed was i am not getting an RPM reading when i am cranking the engine, and i lose power to the ECU while cranking, if not plugged into a charge box. below is my settings, trigger scope and syncing. One issue (maybe the problem) is i do not have anyone to crank the engine for me so i can check my timing marks and set offset. i was hoping to get it to run so i could sync my timing. thanks in advance for the help.

neil brown Posted June 1, 2020 Report Share Posted June 1, 2020 What’s the arming voltage in the settings Quote Link to comment Share on other sites More sharing options...
KevR32GTR Posted June 1, 2020 Author Report Share Posted June 1, 2020 Hi Neil, it is 1.5V Quote Link to comment Share on other sites More sharing options...
neil brown Posted June 1, 2020 Report Share Posted June 1, 2020 Try a 1v Quote Link to comment Share on other sites More sharing options...
KevR32GTR Posted June 1, 2020 Author Report Share Posted June 1, 2020 Neil, it says I cannot adjust the arming with this not being a reluctor sensor. Quote Link to comment Share on other sites More sharing options...
KevR32GTR Posted June 1, 2020 Author Report Share Posted June 1, 2020 I set the offset to zero, and reran a trigger scope. Along with not getting RPM, i realized i am not getting spark either. i assume it is because my triggers are not syncing. Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 1, 2020 Report Share Posted June 1, 2020 Can you attach the actual tune and a log of it cranking. Quote Link to comment Share on other sites More sharing options...
KevR32GTR Posted June 1, 2020 Author Report Share Posted June 1, 2020 Hi Adam, attached is my log and calibration file. something i wanted to mention, when i test ignition with a sparklight, i am getting spark during my test.

Adamw Posted June 1, 2020 Report Share Posted June 1, 2020 Ok, I dont see much wrong in your setup. But with zero RPM nothing is going to happen. I have seen before a problem where G4+ does not initialise the triggers correctly after a major change has been made to the trigger settings. Can you try this: Change trigger mode to Subaru V1-6. Do a store and power cycle. This will reinitialise and overwrite all trigger settings. Once reconnected then change your trigger settings back to how they are now and see if you have RPM.

KevR32GTR Posted June 1, 2020 Author Report Share Posted June 1, 2020 Thanks Adam, i tried that and i am still getting the same results. i looked at the gapping for the hall sensors, and they are within the spec that PRP states. i tested power to both cas and crank signals when cranking the engine. CAS stays around 4V, but crank drops to 3/2.5V when cranking. Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 2, 2020 Report Share Posted June 2, 2020 Oh man, sorry I just noticed something very obvious that I missed earlier. Your trigger 1 & 2 are swapped over. You should have the 12 teeth on trigger 1 and the single tooth on trig two but yours is opposite. You dont need to change wiring as the plug-in ecu has dip switches to allow for the different R32/R34 wiring. Have a look at which position your switches are in now and move them to the alternative setting. Quote Link to comment Share on other sites More sharing options...
KevR32GTR Posted June 2, 2020 Author Report Share Posted June 2, 2020 Thanks Adam! i will try this today and report back. i reinstalled the factory CAS last night and it fired right up after i did ECCS sync. i will put on the PRP trigger and try again with the instructions you mention above. thanks for the help.
