RKGarage Posted May 19, 2020 Report Share Posted May 19, 2020 Hey guys Have wired a standalone Link G4+ into my car with Ecu Hold Power, that all works correct. Issue I am having is when the ecu hold power shuts off all the relays connected to the ecu in some way all constantly switch on and off (sounds like a machine gun). I have wired it exactly as the schematics show and also have no 12v direct feeds, all are fed from a relay that gets power to the coil pin 86 or 85 from the Main Ecu relay from pin 87. Ecu hold power on inj 7, that runs to pin 85 providing a ground, pin 86 has constant 12v, pin 30 has constant 12v Pin 87 then feeds the power to the rest of the pin 86's on the relays and also feeds the +14v in cable with the diode in place as it should be. Any tips or tricks to look at? Cheers Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 19, 2020 Report Share Posted May 19, 2020 If it is an ECU that has P&H injector drives (Fury, Xtreme or Thunder), then the ECU hold power will need to be an ign drive rather than injector drive, the P&H inj drives will back feed if connected to a permanently live source.

RKGarage Posted May 20, 2020 Author Report Share Posted May 20, 2020 Its definitely wired to inj 7 as the fury only has 6 ign drives and the car is a 6cyl so all are used. The wiring diagram said to use a injection channel aswell Have changed the rest of the relays to also have the coil grounded through a relay controlled by ignition so that has stopped all those clicking there heads off. Just have the main relay still clicking and 12v still on pin 87 Cheers Quote Link to comment Share on other sites More sharing options...
RKGarage Posted May 20, 2020 Author Report Share Posted May 20, 2020 Update, depinned everything except power, ground, ecu hold power and DI igniton switch. Still happened. Found the injector relay I put in was clicking aswell Disconnected pin 87, still happened, disconnected pin 30 still happened The disconnected 85 and 86 and finally it stopped, ecu turning off as it should after the 10sec. Will repon everything tomoz and hope it all works as should, and then replace relay or check my wiring for injectors whichever is the issue.

Adamw Posted May 20, 2020 Report Share Posted May 20, 2020 It wont work wired to an injector drive. As I said above it can only be an ignition drive with a Fury. Why do you need ecu hold power? Do you have a stepper motor? Quote Link to comment Share on other sites More sharing options...
RKGarage Posted May 21, 2020 Author Report Share Posted May 21, 2020 Ahhh sorry I understand what you mean now, have wired it to a aux 10 and all is working good now. Yes have a 4wire iac stepper motor, next issue Im having is finding out how to turn injection and ignition on so I can start the car and set base timing and angle offset. Have browsed forums and no one seems to mention it. Mine are all assigned correctly yet show them off even while cranking Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 21, 2020 Report Share Posted May 21, 2020 Those runtimes will always show off when the outputs are used for ign and inj. Only when they are used as on/off type aux outputs (such as a fuel pump) then those runtime display the status. So I would expect you already should have fuel and ign working. Quickest check to confirm is open the runtimes screem (F12), go to triggers/limits tab, when cranking make sure there is valid RPM at the top left and no fuel or ign cut in the bottom middle. The move to the fuel tabe and check there is inj Effective PW showing (top right). Quote Link to comment Share on other sites More sharing options...
RKGarage Posted May 21, 2020 Author Report Share Posted May 21, 2020 Ah okay that makes sense I get a rpm reading, trig 1 & ² have a signal Trig 1 error count fluctuates between 1,2 and 3 Ign cut says 92% Cheers Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 21, 2020 Report Share Posted May 21, 2020 Ok, do us a triggerscope while cranking, and attach a copy of your tune too. How to triggerscope: https://1drv.ms/v/s!AiYbYlZQuRHPmidU5V2CmTcv6t2y?e=EWpSPk Quote Link to comment Share on other sites More sharing options...
RKGarage Posted May 21, 2020 Author Report Share Posted May 21, 2020 Okay cheers, appreciate the help! I have attached my tune file and the trigger scope. G4+ Fury VY V6 Turbo Map.pclr Trigger Scope Log 2020-05-21 1;40;07 pm.llg Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 21, 2020 Report Share Posted May 21, 2020 Hmm, ok I dont see much wrong in the triggerscope, it didnt capture a full 2 revolutions but what is there looks fine. One possible cause of the ign cut is the GP RPM limit 1, it has been turned on and has an RPM limit of zero set. It shouldnt activate until 20s after cranking though but I sugest you turn it off for now. If it is still cutting with that limiter turned off, can you do us a short PC log of it cranking.

RKGarage Posted May 21, 2020 Author Report Share Posted May 21, 2020 Awesome, thankyou! Ignition cut has stopped and trig error codes are no longer coming up aswell. May plug fuel pump back in and try start it Cheers Quote Link to comment Share on other sites More sharing options...
RKGarage Posted May 21, 2020 Author Report Share Posted May 21, 2020 Got it all running! Setting offset angle isnt working as it should but ill suss that out after the weekend haha Cheers for the help again Adam, I appreciate it! Quote Link to comment Share on other sites More sharing options...

The number will turn blue if you’ve done it right. Quote Link to comment Share on other sites More sharing options...
