What have you done to your car today?

no logging... got to pay to unlock it. not noticed anything wonky with voltages though. will get injectors checked tomorrow.

****en motec... $300 to unlock 1mb of logging... $560 to unlock lamba control, though I don't know

if I could just log the lamba values without that enabled or not.

That's about the price of a second hand Link... Sounds like you need to get rid of the car! I take it things like compression are fine?

I'm in too deep to give up now... it goes like a wounded bull... just uses a **** load of oil in the process.

compression and leak down tests have good results.

Got fuel injectors back after cleaning etc and they are fine... AEM wideband arrived today... thinking I should have gone for the innovate though as the AEM only reads as rich as 10:1

[Andy_Mac]

Bummer. Their newer X-series may have been the better choice instead, goes as low as 8:1

[Guest]

10:1 is too rich no point in knowing if its running richer than that just lean up fuel till you can see it.

Can it not be legitimately that rich on high boost and high revs?

I can see if bringing it back to 11:1 stops the oil usage anyway.

More like 11.5-12:1 from 14psi-. Some people think that adding fuel prevents knock but its a fallacy. It can cause false knock and ruins the efficency of the burn. Some stock subarus run crazy rich no idea why but see the results when you turn the boost up to 20psi and lean out the whole map to gain 30-40wkw.

Still straightening the bloody TMIC...

EDIT: thought I was done straightening the TMIC, turns out some **** stuffed up the back too...

New addition, thanks to Zenki for his help!

[SpeedySub]

Gave it it a really good wash, degreased under the engine and gave the headlights a good polish. Came up looking really good. Unfortunately photos didn't come out very good. So won't post those.

Adding fuel reduces temperatures which will reduce the chance of knock...

Anyway I have the wideband installed and the fuelling is pretty bad. Around 12:1 at idle and to about 2500 rpm, it then goes leaner moving towards 3000 rpm peaking at 15:1 to 16:1... then starts going

rich again... the richest I've seen on boost so far is 10.4, but it might go richer with more than a short test.

Also needs better accel enrichment as it goes off the gauge lean when the accelerator is first pressed.

Made some top brackets for the front mount so that all the weight is no longer solely on the bottom ones.

Also have this god awefull squeak In the rear end I can't seem to get to the bottom of. Have greased and checked all the swaybar items so know its not them. Greased the upper control arm bushes. Almost sounds like it could be coming further forward like the front rear trailing arm bush but it looks fine to me atleast. Starting to wonder if its the rear shock, seems to have started not long after installing the pink springs so instinct would point me towards something to do with the shock. Only happening on the one side too. So have convinced myself repacking the shock with grease is the way to go as word round other forums is they are under packed from factory anyway. That way i'll be able to rule out it being the shock and it looks like a pretty easy job to kill in an afternoon

bought possumlink and under mani intake, okay: parts will compile until my motorbike is with me so I can modify all at once, then get a tune.

Also, IAT and MAP sensor for afm delete tune right?

Not quite that simple. Pouring fuel into a car to try and reduce knock is daft.

But reducing fuel and not expecting knock is more daft... but hopefully going from low 10s to low 11s will be okay...

going from 10:1 to 12:1 without the ability to monitor knock is stupid.

Here's the V5/6 possum link install:

http://reuben.xpjets.com/random/BH-Conversion/Possumlink-MY99Manual.pdf

Page 6 says it has 2 switchable MAP options, OEM or a 3 bar GM sensor. Probable that the link 3 bar MAP has the same voltages. No mention about an intake air temp sensor though.

There's some good info on the possum link in gotasuby's Ask your tuning questions here thread:

Oh wouldnt recommend tuning without monitoring knock. But altering ignition timing is a damn sight smarter than altering fuel if youre knocking. Dumping fuel in to fight knock because youre running too much timing is the American way.

Sure but I'm not trying to actually tune as such.. just wanting to verify that my oil problem is caused by over fuelling before

spending a $1000 on a tune... because if the problem is not over fuelling the engine has to come out. I could take a few degrees

of timing out at the same time as taking the fuel out to be safe I guess.

[Guest]

Winding it back to above 10 is enough to give you an indication but its rich anywhere below 11:1.

No IAT on the Possumlink.

Also I wouldn't recommend going to the 3 bar MAP unless you really need to run a tonne of boost. i.e. Over 20psi.

As you end end up with very few rows in the cruise area of the tune and it's a pain to try to tune down low.

What I am hearing is I can get the possum link tuned without the MAF sensor, with no extra sensors required, bar the factory ones?

From memory, yes, that is the case.

This makes me happy. And worried. But mainly happy.

Anyone had experiences with MCR in north shore? Any good?

[Guest]

Off to the body shop where the car has been for a month to see progress made, hopefully I like the rear this time, feeling apprehensive.
