Hence why people are scared of him. He knows too much! lol

Thanks Danny you are a great help, switched off min / max values.

I have run the settings you have suggested.

Looks good Idle WOT seems a little slow to get to low 12s.

Yes I have just been watching the PLX Wideband AFR/Lambda gauge for

readings so far.

Will have to do some data logging to check all you have mentioned.

Did 3 runs at the drags Saturday night with first run pinging in 3rd, got off it

and back into it after I selected 4th, ran 12.902 at 116mph.

Not bad concidering I was doing soft launch's 2.3's and being a manual.

2nd run I gave it 4% Fuel at WOT and it didnt ping but surged in 4th.

I was running 3/4 tank of fuel and found it to be odd.

Did one last run and found it to do the same so that was it for the night.

Fuel AFR was 12.2 WOT everyrun with no leans while WOT.

also noticed on the way out it would be sitting on 14.6 to 15.2 then all of a sudden it

would start running high 11 to mid 12's. thinking that Boost sensor to the wastegate

maybe causing these issues, due to its ticking sound I have told yous about.

Its not a gauge issue as the instant fuel mileage also corresponds to it.

When it was running 14.6 to 15.2's I was getting 6.8 litres to the 100 then when it changed

it climbed to 14 litre's per 100k.

Also pulled out and over took a vehicle on the way out while running 11 to 12 AFR's

and it pinged. turn aircond off wound down window and tested for pinging again and not

once, the AFR had also returned to 14.6 to 15.2 AFR.

Thinking that what ever maybe causing it may be the reason of the AFR's changing and the

problem from the track.

I checked for any fault codes and nothing there.

......drags I like your enthusiasm lol. What is your open loop delay blending ramp set to? Factory is 0.025, you will need to increase this to get a faster transition to open loop control.

My head hurts.

[01txr]

Your telling me, I will have a look when I get home.

Think I have find the reason behind the AFR's moving around, think it is all because of

the Boost control solinoid.

It basically started clicking when I did the change of the Plenum, pipe work, IC & Deka's.

Rechecked for any fault codes and still nothing there.

[IH8TOADS]

Solenoid clicking is common, I suspect a deeper problem. It could be a number of things. You said you surged in 4th with 3/4 tank.......1/3 tank I'd say that's ok but this seems odd also. As Danny mentioned earlier check fuel pressure, you may have a greater fuelling issue.

Question, regarding moving around AFR's..

Have you disabled the flange/turbo/cat over temp fueling?

I bet you havent =)

And I bet you have a fuel system issue.. When I get back to melbourne, I'll get you to email me your tune file, and I'll see whats going on..

Also Think I may have been running more boost down the track

as I set the wastegate to 100% instead of 90% where I usually

have it set.

Noticed on the way home when I gave it a squirt in 3rdmandn pulled

approx 5 lengths on my brothers FG XR6Turbo, boost went to 20psi.

Maybe the Fuel pump letting it down at that boost.

Everytime today When I WOT it, it ran clean and 12.1 AFR, mine

you it wasn't from stand still through to 4th gear.

Thinking Fuel pump may not have the flow needed.

I will be fitting a surge tank and 044 pump next up.

This running at good afrs then going very rich is odd.

It just does it randomly back and forth, eg say drive on 80k road stop at lights its

reading 14.6's then next set pull up it is reading 11.9's, it does it while cruising

also. I think when I give it some WOT it returns good for a while then back rich.

So maybe some sort of Airflow, fuel temp setting adjusting it to rich due to the

mods done.

had a look at my generic 10psi tune compared with my 12psi generic and there is

lots of differances.

This tells me I must need to make more adjustments to bring my original

12psi with the Deka injector up to a correct setup.

It would be good if there was descriptions for all settings in Advantage3 or the manual.

It just might make things understandable a little at least.

Will send my tune file for you to check over whenever you are ready danny.

Just dont let any of my secrets out or we may have lots of others cars

running risky like mine LOL.
