Looking for a little electrical help. I have a hcr32 on a Nistune ecu that at first, had problems with holding connection to the software even with the key only in the on position with the engine off(so not an electical noise issue). Now, I cannot connect to the ecu at all with Nistune, or data scan software. I have tried different cables, different laptops, even re-wired a new consult port in. After that I tired the paper clip jump trick to get codes to flash and nothing worked. I have just got another oem ecu, and still have no luck. I’m quite stuck now and id appreciate any help. Thanks

Does the car start and run?
If ecu is not getting power check ECCS relay and associated fuse

If just a communication issue test the continuity of the wiring from the consult port to the ecu

The car starts and runs great. I also tested the wiring from the consult port to ecu and everything was good, even rewired a new port and still no luck.

ok, double check the continuity/resistance of the consult plug wiring and correct connections at ecu and port.
Have a re-read of this Nistune Diagnostic/Connection issue guide

for it to be an issue with the factory ecu in my opinion it is a wiring/pinout issue

The consult wiring guide is the guide I used to rewire my consult port to a new wiring specialties pig tail. I have 12v and a ground, but I’m not sure what I should be seeing at the Rx, tx, and clk connections, if anything.

    • I do have a tiny tiny misfire occasionally but I think it's because I got a little fuel down into a plug tube so I'll pull the coils out and see if I can dry those out. 
    • Ok, so here the embarrassing 'fess up' post. Here's the crack, or broken part of the old valve cover. Pretty obvious break and in hindsight it's quite the face palmer 🤦‍♂️ but let me explain why I didn't think this was a problem. This side part of the valve cover is an additional piece, it protrudes from the main valve cover and it's also where the fuel rail mounts.....  You can see the rail at the bottom and you can see this external piece hanging off the side of the cover. It almost looks sandwiched in this pic.  Here's another cover with that side piece ...  On top of this, when looking at the inside of the cover, there were no openings(*) for that section. So I really just thought I'd broken some crispy plastic mount for the fuel rail.... Until somebody drew my attention to the air openings at the BOTTOM of the cover, not INSIDE the cover. So, I had a ginormous PCV leak. The cover needed to go and I should have taken everybodies advice and got a new one in the first place. The original one is just fried, its really brittle. It was nice to have the new one be really snug in position and the screws were slightly tight to do up which was completely different to the original ones that almost undid themselves.    
    • Pulled out this pile of shit, will be refreshed soon enough. Had coolant hit my face and I accidentally tasted it.  It's sweet.
    • Looks awesome. Well done. I'd love to drive Laguna Seca! 
    • This video is great, the enthusiasm is infectious and it's kind of cute. It's great to see these things being used properly on track, it reminds me of track days of old. It is a bit funny seeing everyone so excited about Skylines, whereas here they're all considered a bit nuggety or shitboxy. If this seems odd to you mr OP, imagine all of us being this giddy about seeing 30 C5 Vettes on a track at once place, full of influencers taking their videos and posting for clout. That said, you did a great job conveying the fun and excitement of a track day, getting out there and just having some damn fun.
