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)

It is the exhaust temp one im talking about, i have a de cat and the sensor is not plugged in and it wasnt flashing before.

There is also a red light under the cat over heating light what is that light for thats the one which was coming on before the exhaust temp one did?

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
