Hi all, I’m on the home stretch of my single turbo conversion. I hope this post will serve as a second source of information and troubleshooting guide for myself and possibly others. I’m sure there are things I can learn from you guys who have done this before. Base Map: Now when I load the R32 GTR basemap and have yet to change anything (updated firmware, calibrated MAP and TPS). Where should I start in terms of correcting necessary settings on PCLink. Any help is greatly appreciated. I’m a complete beginner on this ECU, or any ECU in fact. But the goal is to get the car started and idling well. From what I’ve read on the forum, set injector master pulse(4ms?)(if lean increase PW, if rich lower PW) set injector dead times as per the fuel pressure. In this case 30 advised by NZEFI. How about dwell time? I will be using R8 coils (see part below) What about timing? Given my mechanical timing components are installed properly, how is timing set on the ecu? Will I need a timing light as soon as it’s running? Lastly, will I have to do this? It says: “In your trigger settings, Set engine type to RB26, set widest slot to 24deg, then set test ECCS sync to off (this must be done last). Do a store, then crank it again and tell us if it now shows RPM. All the other stuff is irrelevant for now. The GTR doesnt have an oil pressure sensor connected to the ECU, the sensor is connected to the gauge in the dash only. Your air temp sensor is connected to AN Temp 2, so turn AN Temp 3 off and put the below setings in AN Temp 2. The AN Volt 6 error is because the oxygen sensor wont output voltage until it is warmed up. We can change the fault setting so that doesnt report an error later.” Anyways, there’s a bit more things to button up but I want to have a solid idea when I’m ready to turn the engine over. Should I subscribe for the gold membership at HPAcademy or I can get by first start/idle with the Link forum?

The slack is just right and seems to follow the instruction manual. I lined up the notches on the intake and exhaust cam and the balancer against the backplate covers and TDC seems to line up with all the marks (belt marks included) - Do I need to set timing in the ECU config?

Hi Guys, Looking for some guidance on what would be the best approach to wire in the Link CAN Lambda unit to an R32 GTR. Should I run an independent relay from the battery to power this unit or is there a way to tap into the factory loom where the ECU plugs in, to provide switched power to this? Cheers. Jed
Good afternoon, I have had a Link G4 in my r32 for a while now and have just gone from an RB25/30 to an RB26 in my r32 gts4. The whole loom and drive line has been converted over. I'm currently running a Garrett T04z and would like to push the engine setup beyond the realms of the On board 1.5 bar map sensor. I would also like to do this without potentially having an aftermarket boost controller and just be able to run it directly from the on board computer. Is there a map sensor that I can upgrade too on the board itself? I do have an extension cable for the IAT that had to be mounted for the old setup, to which i no longer need for that for obvious reasons. My Link G4 is the equivalent to the Vipec V44, its a 2008 in it, maybe 2009, any and all help would be much appreciated. Thanks, Rob.
