Im pretty sure the avcr settings you are using are way off the mark. 70 duty cycle is too too much.best you switch that off for the time being.if you can wait ill try get my settings for you so you have a ballpark setting figure.

Try the link below that will give you an idea of basic settings.i used this article to set mine up.

also do this one after the above link.this is the advanced settings.

the settings are very delicate so double check.one wrong sensor selection can overboos the engine into oblivion so be careful :-)

"Start Duty Cycle is set to +10 for all gears"

this setting is used to acheive different boost for each individual gear so set it to 0 for now.}

also make sure the hoses from the turbo to the valve are correctly connected.see below

"Connect the vacuum line from the waste-gate to the "COM" side of the solenoid, and Connect the vacuum line from the turbo to the "ON" side of the solenoid"}

Muzzy

Great information, and a new SoarerCentral record for uninterrupted serial posting. 7 useful informative posts in a row without interruption by the same member. Have you got something against long posts (of which I am a guilty repeat offender)? An impressive feat anyway.

Ha ha Roger! Me just wanted to get his post count up, leave him alone :-)

Seriously though, Muzzy, I think you are dead right, I think something is amiss with the AVC-R. I will switch it off, or disconnect it and start again, but I will also change the pressure line location from the Fuel Pressure Regulator to the VSV as Manny suggested (I am at work today, so I have to wait until I get home).

If you could pull those values on your AVC-R that would be great! I am sure mine will differ a little bit, but it shouldn't really be a lot.

Neil, sorry mate, but I am a little lost with your post (I am guessing candles are spark plugs?) and my coil packs don't have any finned bits that I can see?

Troy, The finned thing Neil is refering to is the cover over the top of the coils that is held on with all those hex head screws. The one on top of the engine.

Ah, well in that case, I have already tried that. I didn't put it back on when I took it for a drive after I did the compression test yesterday.

i will do it for you mate.
first thing to do is check wiring to ecu then fix the avcr map sensor input..

then we will go over the settings.

ok here is the basic settings mine is working with....

setting menu

boost duty
0.80 kgcm
Duty 42%

Scramble
all set to 0

Ne point
2500 to 8000 rpm

Fb speed
33333

learn gear
0000X

Start Duty
all set to 0%
(start duty is used to set varying boost levels in diferent gears.like if you wanted 10 psi in 1st gear and jump to 15psi in second you would do that from this menu.)

Car select
6 4 >

sensor select
relative 1 (if set to any other in this menu boost will be uncontrolable i should know it happened...!

Gear judge
this setting is for auto best you do it for your own car but these are my setings...

1st 120
2nd 075
3rd 050
4th 035

Graphic scale
bs -2.0kgcm
ne- 8000rpm
sp- 300kmh

thats about all i can think of..

Cool! Thanks Muzzy. I will put them in to my AVC-R and see how close they are to controlling my car. (I will have to double check my sensor select, I didn't put it in, one of my friends entered that one, but he is used to Nissan's and I don't know what the Nissan's have to set theirs to).

Didn't get a chance the last 2 days to clean the oil out of the head valleys and off the coil pack extensions. Benn getting home from work when it is dark. I will do it this weekend, and move the AVC-R sensor pipe off the fuel pressure regulator line and on to the VSV line.

Will let you know over the weekend. Thanks everyone!

Troy,

As a mad keen drag racing fan/family I was going to go to Newman until friggin uni got in the way. Oh well.

Did you see my dad racing? He was on the red Kawasaki drag bike, got the fastest speed on the day (some pissy 210kmh or so, cop with speed camera couldn't keep it targeted for long enough).

What was your best ET/speed on the day?

Hey Luke, I am not really in to bikes, so I didn't take much notice of them sorry. The only one I really noticed was the purple one. Does your dad have a beard? I might have seen him cause the bike riders were next to us.

As your dad might have told you, the timing was really out, so I only managed a 15.21 as a best time on my second run. My 3rd and 4th runs were better, but I didn't get a time for them? I didn't get any speeds at all, all of mine were just times. In case every one is wondering about the terrible time (15.21), the drag event does not have proper equipment, hence why supercharged 454's with NOS and massive slicks only get like 12 second passes. Friend of mine with a green supercharged 5.7L VY SS Ute with cams and headwork getting 410KW at the wheels was only getting high 12's on slicks. We think that the timing is deliberately slowed so that it doesn't go below 10 seconds, cause then people need roll cages and tailshaft loops, and there needs to be more fire marshalls etc. But that is just us guessing. I mean, my car ran a 14.86 stock on my friends G-Tech, so after putting on an AVC-R at 1 bar, FCD, FMIC, Pod, dumps and exhaust, it should be around a low 13 at a guess? What does everyone else think? I know the car wasn;t running right, but it was still a lot more powerful than what it was stock.

Pity you didn't make it to the drags though Luke, 2 Soarers would have been fun!

Troy would you believe same thing is happening to me! I just installed my GReddy Profec Spec 2 or something like that.

I have to put my set point up (high%) and its hardly boosting. Funny thing happened though, I am pretty sure I hit boost cut at .82 so I am thinking maybe the boost reading is not right.

Found my problem mate, it was spiking on mine. Prob. not your problem, but just played with the settings. 35% boost, 15% gain, and 0.65 for holding the wastegates. Gives me 0.92 boost.

Checked my peak hold and said I was hitting 1.03 at 35% before while the screen said I only got .82. So big spike at one point ;)

Hi Luke, I had a look at the video's that we got last night and I saw your dad's bike. It was right in front of where I was standing when I wasn't racing! ha ha...

In other news though, I did a major clean and tidy on the weekend. I pulled off all of the coil packs and went over them meticulously to remove all of the oil that was on them (And there was a lot!). I just used a dry rag, no water and no degreaser. I just wiped it all off. They came up very clean. 2 or 3 of the coil packs had cracks in the plastic on the legs that go down to the spark plug. Is this worth worrying about? ie Does this mean that there is going to be a problem inside the plastic casing?

I then tightened up the rocker covers (They were quite loose, hence all the oil in the head valley). I then sprayed degreaser in to the head valley and thoroughly washed out all of the grease and oil that was built up in between the heads. It is now quite clean.

I then removed all of the spark plugs and cleaned the oil off the threads and checked the electrodes. They were clean, so I can rest easy now knowing that the oil was just leaking in from the rocker covers being loose, and that I didn't have a bigger problem.

After everything was cleaned and reassembled and dried, I then moved the AVC-R's pressure tubing from the Fuel Pressure regulator and replaced the FPR tube with a new piece of silicon tube. I then placed the AVC-R pressure sensor tube on to the manifold tube closest to the oil dipstick as per Manny's advise in "Mechanical boost gauge" in the Mechanical section.

I then fired up the car and took it for a drive for 30 minutes to make sure all of the water had evaporated from the plugs and the heads.

The car is running fairly well now, compared to a few days ago, but it is still only as good as it was in Newman. That is, it still has a missing sound when going through gear changes, and the car still doesn't seem to be all that powerful. It is more powerful than stock, but it still doesn't seem to have as much power as what I had expected from the mods I had done.

Also, the turbo's still don't seem to want to create as much boost as they should. I entered in all of Muzzy's figures and the boost dropped way down to 0.7 or so.

I don't know where to go from here, but I think I might have to replace the coils at the very least...

Any suggestions or more things to check?

i would suggest your head gasket is shot if you had to retention the head to stop the oil from seeping through. so even though the cylinders may seem ok when doing a compression test, it wont show the problem with the head gasket. it only has to be very minor and might not even cause your car to over heat, but enough to cause your car to miss
