No Speedo, Warning Lights, Rough Gear Changes After Belt Slipping.

So I've had a belt that was slipping/screaming on start up for a few months now and hadn't gotten around to fixing It.

Today when I started the car it took a long time to stop slipping and was running pretty rough. Clunking through gears etc.

Then all of a sudden I lost the speedo, temperature guage is moving up and down sporadically, pretty much every guage is acting strange and I have ABS warning light and AT check warning light.

Any thoughts as to what might be causing this? Seems unusual that it would have anything to do with the belt and maybe that's just a coincidence? ECU problem perhaps?

Help!

Just saw you profile pic. So m35? Could be two issues. The dash lights and rough sounds like water in the battery box. Common issue when the drain bung gets blocked from years of build up

So the alternator belt is slipping, and you're having voltage related issues?

Change the belt, tension it correctly, then load test the battery.

The start of winter is when they tend to fail.

Mine is not an M35, it is a C34 S1. Had the same issues with the dash. Slipping belts is a Stagea thing. Keeping the belt tension correct is an ongoing issue.I use two Gel batteries, and one was crook. Replaced battery but did not fix dash. Had to take one out of the Dayz. Problem fixed.

      R32 GTS (RB20DE) clogged cat

      Appreciate the feedback. It is street car, but not a daily. Last week I got a quote from a good exhaust shop for a decat, one which is bolt-on, bolt-off to be easily replaceable. I got quoted for around €150. I usually do push the motor, but I wasn't in this case to make sure that no damage is done until I get the cat sorted. I think it's best to also ask the exhaust shop for the other option and see what they can do. If (big if) I were to decat though, would it be best to tune the car or would the stock ECU handle it? As far as I know, the stock ECU is not tunable and that would require additional purchases.

      As above, definitely bash it or get it replaced with a high flow unit.

      Duncan's V37.......race car?

      Right, its been a while for updating this car, but I made some small but important progress today. In the end I bought an Ecutek dongle from the Australian distributor Tunehouse (for local hardware support) but have gone with a remote tune from Racebox in the US (because they have done millions of these, and I could not find any tuner where I could access the tune anyway as they are all password locked). The App is reasonably easy to work with, but the PC software reminds me of Haltech's ECU Manager that you need to use with the Plat Pro ECUs, it is a nightmare.  Anyway, I sent the details over, got back a tune file and a request for data logs. I finally got a chance to access a private test track today as they want redline logs in 3rd and 4th, and have sent them back for the first round of reviews. The main difference in the tune is going from 1.0 (stock) to 1.3 bar (19psi), although I'm sure is a lot of other stuff in the background. Keeping in mind this is a dead stock car with 125,000klm, this is what the App's performance test claimed: Before After Interesting to note that both 400m tests had the same terminal speed (158klm/h) but different ETs. And no, the speed limiter seems to be higher than that at 186kl/h. Summary of the key logged parameters for the 3rd and 4th gear runs were: Those little turbos were certainly whizzing at 200,000rpm+.  Also I'm really not that excited about oil pressure 55psi at redline so I think I'll go thicker than 5w30 (nissan recommend 0w20....) and see if that improves it. Other than that (and the big boost spike....) everything looks good as a start to me.
