Make The Pain Stop!

Sourbastard · 11-03-2005, 06:42 PM

Well as some of you know, since the cam installed, my fuel economy has been out the window. I fixed a loose throttle cable which I thought might solve the problem, but after a week, the short lived fuel savings blew out again to the 17.5l/100km mark, down from 18l/100km. (Yay)

Another trip into Road & Track Services.
Another Diagnostic.

Apparently the Idle Vacuum is only 15 inches, hence why the car is overdelivering fuel at idle, the ECU believes the throttle body is open, when it is not. Apparently the only way to fix this is a vernier gear to adjust the cam "just so" to get idle working properly again.

At only $110 for the gear itself and no install/dyno cost I guess I cant complain, but this drama has been dragging on for over 2 months, and I just want this to end and work correctly. Before I die or retire.

If you posted me $500 it would go some way towards making my pain stop.

Get the vernier, cant be many more bits to replace now.

No pyramids but I do have a MP3 that mentions egyptian crocodiles.

You'd never sell the AU thats just giving in easy!!!

Sourbastard · 11-03-2005, 11:28 PM

Ive got an 82 litre tank.. my DTE always reads under 300k once ive filled up. I dont think its bloody kidding either! lol

No way this be normal for us though stav, v8's get better mileage. Even with a good caning.

**Stav** · 12-03-2005, 12:52 AM

I agree.Mine had crap economy even with standard motor.So I will be trying a new hego sensor for luck!!

xr8ute · 12-03-2005, 12:54 AM

bloody hell...I've got the 82 litre tank in my XR8 and I get 550km on a bad week.

hope you can find out where all your fuel is going.

loxxr6 · 13-03-2005, 01:55 AM

haha dirty injectors, less flow = better economy.

I might start putting dirt in the tank....

I think I average at least 450 a tank....but then I haven't filled up my tank in ages. The change to premium fuel has hurt the wallet somewhat.

Its funny that!!! You have 8 injectors ,we have 6 and were using more fuel.There has got to be something better!!!Maybe our plastic tanks allow transpiration of fuel???

champ let us know how it goes.I hope it improves.Mine was bad before the cam and now about the same!! A new ego and map sensor may help a bit here and a prayer tonight!! :newangel:

**FTE217** · 14-03-2005, 08:53 AM

my normal spirited driving returns me between 380 - 450 dte.....on a recent drive to Albury 778dte.....but if I really give it to her I'd get a dte of 200 lol or less

TheSneakiness · 14-03-2005, 10:56 AM

I get 1300+ kays outta my tank(s). And one of them only cost $25 to fill COMPLETELY.

**Uncle_Ken** · 14-03-2005, 09:57 PM

My stock AUII with a tickford snorlke gets 450 kms in Sydney traffic from a 68 litre tank. I'm paying a $1.10 a litre so 300 kms form an 82 got to hurt.
Its not stuck in first gear?

I've seen my Fairlane's 68 litre tank at read 633 on the DTE after filling up on BP Ultimate. I guess that's pretty good? Wasn't going highway speeds.

EFFalcon · 16-03-2005, 02:46 PM

i get better then those figures on LPG :o
i get roughly 400-450km's to 68litres on gas... thats ridiculous.

Sourbastard · 16-03-2005, 03:08 PM

Ute went in today for vernier gear and new autolite 985 plugs from mr Mockopolos

Hopefully this will be resolved today.

Sourbastard · 16-03-2005, 08:46 PM

Good news. Power has returned down low, economy seems to be improving quickly if DTE is something to be believed.

Bad news. Just noticed someone has either run into the back of the ute while at the mechanics, or one of their braindead moronic cretin like employees has backed my ute into something. Whole back bumper will need to be replaced.

**Stav** · 16-03-2005, 10:38 PM

Goos to hear economy back ..bad about the bumper bar.

Walkinshaw · 16-03-2005, 11:57 PM

What sort of labour cost was involved with dialing in the veneer and advancing the cam a few degrees?

nothing, i just paid for the vernier gear.

TheSneakiness · 17-03-2005, 09:57 AM

Get them fuggers to pay for that bumper damage sourbastard.

Dauphin · 17-03-2005, 10:18 AM

Bloody hell! Good luck with taking it back to them concerning the damage. Once I picked up my car from a repair shop after they had to cancel due to too much work. All I wanted was a deep right-side bumper scratch done. I then went straight to a shopping centre and came back to the car to find the left-side had been keyed - two doors and rear quarter panel. I did wonder if it had been done at the mechanics, tho.

Sourbastard · 17-03-2005, 10:23 AM

Went and saw them this morning, damage will be fixed by the panel beater next week, so all sorted.

car is flying today, idle is still lumpyish, but more stable then before and not associated with massively rich fuel smell wafting through the cabin of the ute.

So its just back to that familar smell of sulpher and old socks?

Sourbastard · 17-03-2005, 10:36 AM

well atleast mine doesnt smell like 3 day old mexican food passed through a set of badly crocheted underwear. :P

loxxr6 · 17-03-2005, 02:18 PM

So has it been dyno'd again or do they think the results should be pretty comparable to last time ?

Sourbastard · 17-03-2005, 02:25 PM

yeah its been dyno'd again, making a bit less power at peak, but the curve has shifted up and the left everywhere else over the old curve.

I noticed there before vernier dyno was less then my previous dyno with the cam and chip.

yeah that doesnt sound complicated... not... lol

Sox · 17-03-2005, 02:32 PM

Funny that, there was a thread the other day with many saying it's not necessary to have a vernier gear.

I wasn't one of them......

Sourbastard · 17-03-2005, 02:44 PM

I wouldnt fit a cam without one on a 6 now. Granted I still need to keep an eye on fuel consumption over this week to see how it goes, but if only for fine tuning the cam for power, its made a huge difference to my setup.

**Stav** · 18-03-2005, 03:17 PM

Verniers are essential to get the best out of the cam. I had mine advanced a tad today and already see a difference down low and better idle etc.

Sourbastard · 31-03-2005, 08:50 AM

Its going alot better now mate, fuel has dropped to about 16-14l/100 depending on temps, traffic and how hard I cane her. I might looking at getting a dyno in shootout mode done once ive had my transmission serviced.
