I'd try logging your long term fuel trim and see what it is saying too
-
What exactly do you mean by running rich? As your long term fuel trims are pulling fuel out? Or measuring on a wideband?

Combined States Snowy Cruise - November 2021
El Andrew replied to EvilDaifu's topic in New South Wales
Definitely looking unlikely just now. We will cruise again though! -
Chucked diff bushes in this morning and all good now. Jet was a legend and confirmed the factory data sheet numbers were no good. Have some numbers in it now to let it start, which confirms it's a tune issue so I can put the spanners away. Scaling the low slope in the driveway will be fine to get it close. High slope will have to wait until after lockdown! Good point though Puff - pulling that quick connect would have been a quicker way to confirm pump had voltage and was flowing fuel!

Just to continue documenting my inner monologue... Figured if the car really is immobilised and cutting the fuel pump, causing no fuel pressure when priming, then I should be able to confirm by checking voltage at pump when cranking. Pulled the pump connector off and hooked up test light. Has voltage with key on during initial prime, then voltage again when cranking. I think that's good news. Must be losing fuel pressure someone, so think I need to pull the rail again and recheck all of my steps. But hopefully we are talking a mechanical issue now rather than an electrical/immobilisation issue.

Hey everyone Bit of a head scratch here. As you know, I threw Bosch 980cc injectors into the car the other day. Also been tracing a wiring issue with my transmission cooler fan (which turned out to be a bad crimp that had pulled loose under the dash), so a bit of mucking around with multimeters and of course disconnected the battery while doing the injectors. Got busy with work and aorund the house, so only got around to hooking the battery back up, loading in a tune with updated injector parameters and starting it yesterday. Well, tried to start it... Pump primes, car cranks but doesn't fire. Not even any coughs and stumbles, so seems like no fuel or no spark. Jump start pack didn't help either, so left the battery on charge overnight. Exide battery about 12m old. Tried to start it today - same problem. Checked I'd plugged everything back in properly an all seems fine. Checked all fuses. (I'd removed the throttle body to get access to the fuel rail.) I reflashed the tune but no dice. I'm using the Raceworks 4 bar data for the injectors as my starting point. I even pulled the parameters for Bosch 980cc from an old post from @Puffwagon and loaded those parameters in. I imagine though even if the data was way out, it would at least cough and splutter and try to start. Scanned for codes and I got the usual P1000, U1900 which are common with some code readers. But also got P1260 - theft detected. Cleared that, tried again, but no luck. And the code is back. Got the 8 year old to watch the fuel pressure gauge while I cranked - I assume it should stay at 4 bar, but he said it dropped. Took video to confirm - https://youtu.be/y1oBXQGKNPU So it looks like no fuel pressure, which I'm assuming is due to the theft detected issue. Obviously didn't like something I did when I disconnected battery (I possibly unhooked the battery while the car was locked). I've currently (boom-tish) got the battery disconnected to hopefully reset everything so I can try again tomorrow. I could retrace my steps and put the old injectors back in with the previous tune, but I'm doubtful that's the issue. I'll try that if I comes to it though. Could even put the factory reg in (has a GFB reg), or hook the battery up to the original cables where the turbo-side airbox currently is, to eliminate any battery cable issues. It does crank though... Any other suggestions anyone can think of? Presumably unrelatedly, when doing all of this I've noticed that when I release the key when cranking it keeps cranking until I turn the key off. I've also had a couple of cocasions in the past few months where I've gone to crank and nothing happens. If I switch off completely and retry, it has been fine. So maybe starter solenoid is on the way out - but seems unrelated? At least I'm in lockdown so don't need the car tomorrow or anything!

It's a nice idea, but I'm not sure it would be worth it. Extra gears will give better economy I guess. Having a ton of gears when in manual mode through the twisties would be annoying I reckon.

Change down manually rather than triggering a kickdown and the ZF won't give a rat's about dealing with 300

Injectors went in and I've primed the pump a few times to check for leaks. Updated my tune file but haven't flashed it in. Then had a dream last night that the car was running like crap and I took it to a mechanic. As I was explaining the problem I suddenly remembered I hadn't flashed the new tune in. I should probably head out with the laptop so I don't have nightmares again tonight.

Yep! Bosch 1150s going in. Plus the trans fan stopped working so chasing a wiring issue. Probably pulled a crimp out somewhere when I redid the wideband the other week. Proper soldering iron arriving Friday [emoji16]

Happy birthday Keith! ACT on the lockdown train too. When I'm not working, I'm spending lockdown the right way:

Wheels don't actually look so bad in that shot!

Have you tried a new O2 sensor? Only $60 or so and can cause some stalling issues. If it's never been done it really is a service item anyway.

Reputable tuner singing a different tune to the forum...
El Andrew replied to FGeorge's topic in General Tech
Haha sounds like the 'professional' tune that was in my car when I bought it - all the boost, all the timing, hey knock sensors it's your turn to bat. Makes my a-hole pucker thinking about it, but in practice it worked as long as the knock sensors didn't fail. -
Pretty sure I just went to a radiator place and they welded on a 1 inch pipe with a rolled end on the spot. Just mark it in the car first so you get it where you want it
-
Don't think it will up on top, but if it does then I guess I'm suddenly venting to atmosphere!
-
These pics give you some idea of how I did mine
-
I found it a bit over the top to start with. So I replaced the middle muffler with a resonator to balance out the induction noise [emoji1787]
-
I've got the same kit and got a thingo welded onto the metal pipe elbow that the filter attaches to. If you are going to the effort of plumbing back you may as well make it legal. I think I used oil drum hose so it was oil resistant, but in reality there ain't much oil going in there. Was just what I could find that was black.

Nice work Keith - dogs are fun to have around. Bought a pod for when we take the dog away and he fills up the boot. Ordered a nudge bar from East Coast Bullbars for the Outback. Told the wife it was good to support Sydney businesses (which it is). Was about to order a light bar for it too, and got told to leave her car alone and stick to modifying my own. So I did. New injectors were delivered yesterday.

Latter one could be fun. Two bottles of whiskey and then clean the dogs teeth.

Sounds fun - my first one is on Monday. Sounds like I might as well drink two bottles of whiskey.
