Happy Birthday Ian

Small walk about today. 20230826_165254.mp4

Had a small coolant leak too which resulted in loosing about 1/2 a litre on the floor so let it cool down, After i could handle the pipes I tightened everything up and we are good to go again. Engine now up to temperature and a slight rattle from the upper left but should be ok after the oil is run through for a bit. 2023-08-26 15.39.20.mp4

Learned how to do timing with a Link G4+ Learning curve but got there in the end, actually easier to do as you don't need to touch the CAS.

Update on this, taken exhaust pipes back off and dropped them at a local welder to put some new ports on. Moved position closer to drive shaft and pointing up.

Not kidding, The supplier i purchased my original ECU from over 5 years ago cocked up someone elses order and sent it to me. Likely about 2K in Parts. I've contacted Link via another supplier to check the serial number on the ECU and now i'm awaiting instructions. Shame its for a S13, what a waste as i could have upgraded mine to the latest model.

Next job to do is get the wideband sensors moved. As you can see below they are far too low. I'm thinking about moving them into the void between the gearbox and driveshaft. Near where the hanger is on the below picture :

She's Alive ! ECU Loom issue now resolved and also managed to tighten the belts. Still needs properly tuned so not about to go start revving it or anything. Next date for the diary is the 28th when i take it back up to DynaTune. 2023-08-09 17.08.31.mp4

Brother came round and assisted me on tightening them up. Issue now resolved.

Topped up the coolant and bought some new battery tie rods as the oem ones were too short for my new battery. Also need to jack the car up again today and remove the exhaust as the lambda sensor mounts are wrong. The location that's been drilled for them is way too low.

He's a great guy, diagnosed the fault very quickly. However had to take it back home to figure out what the issue was by tracing the fault. After it was home I managed to trace and fix it. Now I just need to book it in with him again.

Fixed my Injector issue and now moving onto very squeaky belts. I have tried to tighten and slacken them but they are like a scream from the deepest darkest chasm of hell. How do i sort them ?

I was but by the time i replied i had already done what you suggested and fixed the issue.

Its just a bad placement of the pin by the manufacturer. I have taken a few pictures and emailed them about the issue but i'm not paying to send it back over 5mm of space to move a pin.

Dont need to fully remove the loom, just need to release the pin 115 and swap it over to pin 114 where it should be.

Pondering to remove the loom now, but to do that i need to remove part of the dash.

Why does shit like this always happen to me. Wiring Specialties have royally screwed the build of the loom and mixed up the pinout to Injector 6. Tracing it back i get the Injector Socket 6 (Pin 1) going to Pin 115 on the ECU which is for the 'O2 Sensor Ground' The correct port should be 114 according to the ECU pin guide below. Getting 12v coming in on pin 115 also scares me as that says it a ground connection. I have emailed the manufacturer to see what they say but i think the full loom needs to be sent back to be fixed.

Also the small test lamp which was real handy. 2023-08-08 10.38.21.mp4

Small clip of the first start, prior to figuring out the inject was stuck on. 2023-08-08 09.09.50.mp4

So for anyone who hasn't seen my facebook posts today my little mapping trip didn't go to plan - again. However i haven't came away with complete bad news as with the assistance of DynaTune we diagnosed the issue. It turns out my new loom has permanent voltage going to injector plug 6 which in turn floods that cylinder. Bummer, as its a brand new loom from wiring specialties. Good news is we didn't flood it before this was noticed and we now know exactly where to put attention on next to fix the issue. To test the injector harness we used this little glow plug which cam in handy.

Locked and Loaded - on the trailer ! Ready for its first official start and mapping session on Tuesday.

Would a UK breaker still work ? As its a left hand drive and american the harness will be reversed.

Yeh, Looks like its been used for parts on a previous life. Although never seen a zed that required replacement back end harness. Has it been cut at the fuse box or has it all been unplugged as its a big bloody harness to take out carefully.

I do not believe they are compatible plug wise, may work with a retro fit but likely not worth doing. Stolen off TwinTurbo.net http://twinturbo.net/nissan/300zx/forums/technical/view/1165129/The-three-types-of-speedometer-gauges-how-to-identify.html
