Dawes and Needle valve issues

[Dinger]

I am pretty sure the set up is correct I have just been unable to get the settings correct.
The rig goes into limp mode at 2600 and 31-3200 rpms.
I have the boost set to 15 psi it runs at 10 psi at 22-2300 rpm and 100km/ph
The only part of the initial setup I have not achieved is the 1/4 inch drop at the actuator on start up.
I have replaced the MAF but still get the limp.
Any advice would be appreciated

What did you do with the needle valve? Or how did you set this up? I would wind the needle valve right in and then back it off until the rod drops your 1/4 inch or 10mm or there abouts. Then try again. Sounds like the needle valve is closed off too much.

Hey Mudski,
I started the needle valve wound all the way in clock wise so it is past the 0 mark and then start the rig. I left it for about 1 minute or so but no movt. Not sure if that is long enough? I am pretty sure that that might be the problem I am just not sure how to progress.
It has only started I the last month I had some plumbing issues with the IC but that is all good now (lost a hose clamp)

You shouldn't have to wait mate. The rod should slowly start dropping as you are unwinding the needle valve.
So as mudski said, wind the needle in fully clockwise (forget the numbers on the valve). Then start the car, and slowly unwind until it drops about 10mm. Then go for a spin and see what happens.

Cheers guys I will give it a crack tomorrow and let you know how I went

[mudski]

shut the vacuum supply right off. Totally, start the car and slowly watch the rod drop down while you are opening up the needle valve, and stop at about 10mm. Then have another go.

Did a couple of runs today things are little more stable I will keep tweaking and see where I end up.
thanks for your advice guys

write down any adjustments you make, easier to remember that way IMO
What is your max boost???

[Dinger]

Did 300 km today highway and light 4wd
Still getting limp mode .
Max boost is only getting to 15 psi will turn it up and run again tomorrow.
I only did fine adjustments through the needle
Although when I run in second (auto) I don't have any issues.

I've had similar issues, they way I got around it was to lower my max boost to 14psi. Now I don't get any limp mode probs, and I can't feel any difference with 1 psi lower.
