Hi everyone.

So I'm having an issue with one of my coil packs, I found one of them blow out (pack 4)so I replaced them all, they are not the best of the best coil packs, I only paid $220 for 6 of them, anyway I replaced them an now the same one (pack 4) has blow again, Iv checked how much power each pack is getting thinking it could have been the harness but that seams to be good, just seeing if anyone has had the same issue or might know what the problem could be, thanks.

The picture is of the first coil pack I took out that was blown an the second one did the same thing.

How likely could it be the timing of the dwell on the ecu to keep stuffing up that 4th pack?

The dwell is the same on all six though, right? Higher dwell will run them hotter, so you would expect that to reduce their life, but I would expect that worst case it would just kill the primary coil, which would then become an open or short circuit. That big chunk out of the side is some weird shit.

Do you have an aftermarket ECU?

I'm not sure if the dwell is the same for all six, how would I find that out?

Iv only had the car for three or so months now an it does need a tune..

Can the dwell affect just one pack? Maybe it's too high on pack 4 an keeps burning it out?

An I'm running a 6860 ecu

      Thanks for that Paul.  Do you think if I posted a picture you'd be able to remember where it went?

      Sorry Duncan, I didn't get a notification for the replies.  Thanks for responding!  It's a full Android device, but does allow you to use CarPlay/AA as well.  This is the one I bought from NaviRS on AliExpress: https://www.aliexpress.com/item/1005006368602668.html?spm=a2g0o.order_list.order_list_main.111.59aa1802JDzQ0E - the 2K 8G-256G CAM variant but it seems to have gone up by £170 since I bought it!  My purchase was ￡307.14.   It's not the fastest thing in the world but performs perfectly adequately.  It stays on standby unless I disconnect the battery and let it power down, then it's just a fairly standard Android bootup time from cold.  The DSP Equaliser is very nice and made the standard stereo system sound pretty decent compared to the stock screen.  Perhaps I can take a video of it when I get a sec. It *allegedly* supports the reverse camera, but I'm yet to get that working.  It has options for reverse cam (a camera unit can be bought separately) or 360 cameras (also bought separately).  To be fair it doesn't seem to detect that the shifter was put into reverse but I'm working on a theory about this as well.  At the moment I'm going without which is a bit annoying considering the car is an absolute canal barge but so far I haven't caused any damage I'll grab a picture of the wire I'm missing later today when I can get outside.  My theory, by the by, is that not only is the head unit different, but the CANBUS network has different signals for the different years.  I think this because I have a spare AC panel from a newer Infiniti G37 (as opposed to my Nissan panel) which wouldn't control anything except the volume when I had it wired up with the stock system.  I'm going to throw it back in and see if the screen will respond to it.  I've just ordered an arduino CANBUS module so I can have a look at the signals going around the car and see if I can spot anything.  I'm thinking if I can work out what it's expecting vs what it's getting I might be able to translate and relay the signal back but so far just a theory anyway. I also found this on my travels, so far the only one that specifically matches my car: https://www.aliexpress.com/item/1005002822934280.html?spm=a2g0s.imconversation.0.0.33433e5fgttovi If you look at the picture of the before, it has the card reader slot, and the picture of the head unit is exactly the same as the one pictured in my original post.  I asked if they sell the cables separately but sadly they won't.  I didn't want to just buy this one because it's a super old Android version and only dual core - likely slow as hell.

      As above, you did refill the coolant and burp the system before running it again didn't you?

      To be fair - you see the same thing for every clutch. There's always someone making an installation error.

      Just saw this, redacted names. It's on a R33 GTS-t Facebook group. Looks like still teething issues.
