MichaelR32GTR Posted May 12, 2020 Report Share Posted May 12, 2020 Hello i am running a link g4+ fury in my r32 gtr, I have issues where if u turn ignition on and then off, reds on dash stay on as it’s holding power, funny thing is if I start the car and go for a drive and turn it off then back on it won’t do it when it’s hot, only when cold... anyways my ecu hold power is on “injector 7” channel i have read briefly I might need a diode of some sort if anyone can help me what needs to be done exactly would be much appreciated as always !

Adamw Posted May 12, 2020 Report Share Posted May 12, 2020 You only need ECU hold power for stepper motor idle valves. Why was it wired for hold power? Are you trying to control the factory ECCS relay etc? Quote Link to comment Share on other sites More sharing options...
MichaelR32GTR Posted May 12, 2020 Author Report Share Posted May 12, 2020 Not sure honestly I know with my previous Vioec V88 I never had an issue with this now got a custom milspec plug and play harness from r32 gtr to Fury ecu the plug and play wiring harness pin out diagram says: B connector, Pin 2 - injector 7 “ecu relay control” and in my ecu software injector 7 is ecu hold power which connects to factory ecu engine harness plug Pin 16 - eccs relay Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 12, 2020 Report Share Posted May 12, 2020 Hmm, thats not going to work with a Fury. It looks like the coil of the ECCS relay and the Ign coil relay in an R32GTR are live all the time. The Fury has P&H injector drives so when the ignition switches off, the power will back feed through the injector drive and keep the ecu powered up or partially powered up. Usually you need an ignition drive to control a relay that is live all the time as they cant back feed. I suspect maybe your V88 used an ign drive instead? Unfortunately you have no spare ign drives... I think to solve this you are going to have to add another relay in somewhere to control "pin 16" to the ECCS relay rather than the ecu control it.

MichaelR32GTR Posted May 12, 2020 Author Report Share Posted May 12, 2020 Hmmm ok thanks that’s correct the Vipec v88 was using a spare ignition drive about half way down, Scott said to do what you recommended and use an additional relay, so we are on the right track ! but I’m finding it hard to read his relay diagram which pins go where (hasn’t included eccs relay PIN numbers and I’m not Very familiar with Reading relays diagrams without them) if you are more familiar with them and could help me out that would be awesome Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 13, 2020 Report Share Posted May 13, 2020 The new relay: Pin 85 to ground. Pin 86 to ignition switched +12V (you can use the original ecu wire that goes to pin 45) Pin 30 to ground. Pin 87 to original ECU pin 16 (ECCS relay control). The Link ECU ecu hold power output should be turned off and Inj 7 disconnected from pin 16. The "ign switch" DI is also not needed.

Been busy sorting out other things but almost 100% done now I will be wiring the new relay this week/weekend in regards to the new relay pin 87 to original ecu pin 16 (eccs relay control) should I splice into it or run a new wire from pin 16 to relay 87 thus bypassing the factory eccs relay completely (or do we still need the factory eccs relay wired up and running aswell as the new relay) Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 31, 2020 Report Share Posted May 31, 2020 Leave the eccs relay there. Pin 16 is what turns the eccs relay on - so the new relay pin 87 needs to ground pin 16 to turn it on. Quote Link to comment Share on other sites More sharing options...
MichaelR32GTR Posted May 31, 2020 Author Report Share Posted May 31, 2020 Ok perfect I will splice into pin16 wire and leave the factory eccs wire as is wired up in the background. thanks ! Quote Link to comment Share on other sites More sharing options...
MichaelR32GTR Posted June 1, 2020 Author Report Share Posted June 1, 2020 Done and problem sorted thanks again Adam Quote Link to comment Share on other sites More sharing options...
MichaelR32GTR Posted June 1, 2020 Author Report Share Posted June 1, 2020 I turned the car on and off multiple times and it did it once back feeding out of say 8 times I will keep an eye on it I have Digital input - ignition switch OFF and injector 7 - eccs relay - OFF should I disconnect injector 7 wire that goes to engine harness pin 16 completely as I think that’s what u meant in the reply below or just turn them off in the ecu settings On 5/13/2020 at 10:20 AM, Adamw said: The new relay: Pin 85 to ground.

Adamw Posted June 1, 2020 Report Share Posted June 1, 2020 You need to disconnect inj 7. DI ign sw should be ok to stay connected. MichaelR32GTR 1 Quote Link to comment Share on other sites More sharing options...
MichaelR32GTR Posted June 1, 2020 Author Report Share Posted June 1, 2020 Ok thanks I will de-pin injector 7 from plug B, pin 2 and test again cheers Quote Link to comment Share on other sites More sharing options...
MichaelR32GTR Posted June 2, 2020 Author Report Share Posted June 2, 2020 Removed Plug B - pin 2 (injector 7) turn ignition on and off and still back feeding..... Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 2, 2020 Report Share Posted June 2, 2020 Ok, perhaps there is another aux connected to something live. For some of the stuff that has a relay or fuse you can test by getting it to back feed then pulling the relay/fuse for each aux circuit and if it suddenly switches off then you have found the culprit. Some of them may not be easy to test that way so for those you will have to pull one wire out at a time and do an on/off test. Quote Link to comment Share on other sites More sharing options...
