:D

for those who cant be bothered reading

the engine check light comes on and flashes differently for the following reasons

a sensor out of range or failed - ie water temp sensor, airflow meter, tps - which ever is dead will be highlighted in ETC, SENSOR SW CHECK on the hand controller

injectors reaching 98%

knock exceeding a level of 60

airflow meter reaching 5v

these are defaults on the powerfc and you can change the sequence flash in datalgot, and you can enable/disable the flash on the hand controller via ETC, FUNCTION SELECT

I read that already on your faq. The main reason it could be coming on from the hand controller is the inj-duty reading 100% which i have found out. And as i have said, I am getting the car retuned on thursday and I wont be driving it until then.

hmm thought it would have run a bit lean if it was hitting 100% inj duty and you would have seen a little bit of knock, probably luck you didnt anyway lol

yeah get the tunes and/or injectors sorted and should be alright, The atmo bov thing as said, prob wont run 100% with them but should be good enough to drive around with half decent fuel economy, probably try for a plumback bov in the near future but

best of luck with it

thanks 89cal. I will look at getting a plumb back in the future. The fuel economy thing is not so important to me atm bcos the car is not a daily but i would like to fix it in future. I havent seen any knock higher than 30 so i guess this is a good thing. Will look at getting some bigger injectors and a fuel pump. Tune on thursday so will see how first.

provided everythins working properly (ie fuel reg) 100% with a standard turbo would be rather rich. and lean doesnt always induce knock, i've had my car as lean as 17:1 (fuel reg died) at WOT with the same timing as 12:1 with no change in knock.

as said check light will be from inj duty, turn it off in function select if it annoys you

reading pauls faq, he stated that inj duty at 100% can be fatal though?

of course it can be fatal, the injectors are at 100%

they cannot physically pump in any more fuel

if you hit max inj duty of 100% at 5000rpm and the engine continues to use more air, it will lean out, which places the engine at risk

no engine or tune should max injectors

if you blip 100% at 6980RPM for a slit second its probably ok

but if you hit 100% much earlier and the engine is more on load progressively, its a timebomb

only hitting 100% at redline for a few seconds. its running rich so leaning it out abit, the cycle duty should go down.

ahh yeahh.... sorry ive stuffed up there lol...

What you were saying is 100% inj duty on stock turbo will run rich because the tune would not require that much fuel

Yeah silly me thought the car was hitting 100% duty and still wanting more, but 100% would be lots of fuel with stock turbo

Sorry bout that I wasnt thinking :D

ZXY: Your tuner will sort it out, as long as you know what you want out of the tune he will sort it out for you

of course it can be fatal, the injectors are at 100%

they cannot physically pump in any more fuel

if you hit max inj duty of 100% at 5000rpm and the engine continues to use more air, it will lean out, which places the engine at risk

ONLY if the figures in the map are the correct amounts required for a desirable air fuel ratio. if its running at 10:1 at 100% its not leaning out is it?

entirely agree it can be dangerous, but in this case i highly doubt it really needs anymore fuel

my tuner fixed the rich fuel mixture. But he had to use the hand controller as the powerfc firmware on my ecu was too new for him. He has to update his firmware to tune it. But still better afr now and injectors are around 85% at full throttle

feel alot nicer to drive?

yea feels nicer to drive and its only on 10psi but making good power. Less black soot on my boot as noticed. will go back for a retune when he sorts out his firmware as he only did the tune via controller.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
