Hi Guys got my car dynoed then i noticed engine light was coming on around 4,500rpm rang dyno guy and he said it was afm maxing out and nothing to worry about. Now i checked and was only getting 35 knock max so obviously its not pinging, then last night i noticed that the engine light wasnt coming on anymore and that instead the exhaust temperature light ( the one with the picture of a cat with waves going over it) was coming on instead?? I was running some extra octane boost.

Just means the sensor where the cat is is very very hot. Usually happens after you give the car a good caining in the hills, at least I know mine did.

Mine does the same thing but only after a LOT of punishment in 1st/2nd gear sort of areas if that helps?

Ok thanks mate, weird thing is it came on as soon as i took my 4wd fuse out and put my car in rwd then i gave her some and it started to flash, i put the fuse back in and she still comes on, only thing i can think is that some how the sensor got knocked off the bottom of the car where i had tucked it in.

I adding the octane boost as i filled up with crap caltex fuel and my car started to hit 70 knock so i thought it make a diffence which it did, never using that fuel again!

ok you need to be clear on which one you are talking about

engine check light

or

exhaust temp light

your topic says exhaust temp and the content says engine check light

engine check light - orange engine icon

ehaust temp light - red box with squiggly lines

engine check light

used by powerfc to indicate;

airflow meter maxing out

injectors maxing out

knock exceeded 60

the powerfc faq tells you how to diagnose and check for all 3 items and how to disable/enable them

exhaust temp light;

used by powerfc to indicate;

exhaust cat is too hot

either disable the sensor or get the cat checked (could be blocked)

      You have (externally anyway) a lot of patience!  At the very least your patience has rewarded you financially even if you decided you were over it!! I only just read your first experience of seeing the car, that would have been amazing!  Well documented too! It must be exciting knowing there's only 10 months left until you can get it on a boat and on it's way!!!???

      Yeah, that's when. I guess you could say I'm as patient as I am foolish(or just a masochist?🤔). I've strongly considered throwing in the towel and calling it all quits many times, and have almost done so. It's a first-world problem for sure, but I've had a pretty rough go of it, as well as other factors; hoping something good comes of all this; it has to. It definitely is half the price of the ATS and performs great, but I'd like to try something different for once. I've sampled the ATS in a friend's 32 and it's solid👍

      I know mentally you're set on the ATS clutch but honestly I'm a big fan of the Nismo Super Coppermix Twin. It's much cheaper and in some ways I think it's a better design for a street/circuit car.

      Just checked in first post and you should be able to bring it home November this year, right? I'm amazed you made it through four years of this. As hard as it feels now the rest will go by in a breeze in hindsight, I'm sure.

      Realized I haven't been back here in a while. Still here, still alive, still waiting for the car.  I went back again the only time last year from Oct-Nov for R's Meeting and drove it around some more, including a few laps on Fuji Speedway(in the wet, sadly). The car still feels good, but have a couple small things to address. I've been getting more parts but have slowed down still, and most of the bigger purchases are now out of the way. I find myself getting impatient more and more when it comes to getting started on this project; it's quite hard for me not being able to really dive in and start making this car my own because it's halfway across the world. At times it doesn't even really feel like I own one of these. Haven't really been motivated or had the desire to document the last trip on here or social media for, well, reasons... but here's some pics...it's also still alive and well as you can see: I've narrowed down to the last large part purchases(anything over $2k) before the engine build to be: 1) Ohlins Road & Tracks 2) ATS Twin Carbon clutch 3) Endless BBK with some custom options and 4) Kansai Service carbon driveshaft I don't think the budget exists for all of these this year, but I'll try for one or two items I think. Though, every time I look at my spreadsheet I sigh, shake my head, and get depressed just that little bit more.  'til later.
