Question

Yeah, I know, it should read boost:
Seriously, I've just got a Defi gauge set up and running. It seems to work but I'm not sure what sort of readings it should give.
So far, I've only had it running in the drive, and the gauge hovers over -0.5bar .
Then when running at 4000rpm, it hit +0.1bar
Is this normal?
I can't take it onto the road yet, as there are still,wires to be tidied up, and it's pouring, just for a change.:
Thanks for any responses.

It won't register "real" boost until its being driven (i.e. under load).

Just been out in it for a little play: it peaked at 1.1bar. Does this seem OK?
No evidence of Knock according to the KL I've just fitted, and the LambdaLink was doing a "Knight Rider" imitation, so I'm not sure what that means yet.

My car normally registers at between 0.9 - 1.0 when I push it. Hovers around -0.7 when idling or -0.5 when warming up.

Many thanks to all who helped with this project, even if not directly.
I read LOADS of posts about fitting, positioning etc etc before, during and after the job.
Couldn't have done it without Scoobynet.
Of course, without Scoobynet, I'd probably not have known about it, it wouldn't have cost me loads and I wouldn't have spent best part of two days doing it...............................:

Was the Lambdalink doing the disco when you had WOT Alcazar. If it was it may be on the weak side! You boost is similar to mine as well.

No. Lambda Link was on green with WOT, so I guess it's OK.
I do think some of the instructions could be better: they tell you a lot about what it is, but not a great deal about fitting, what it's supposed to read etc.

Scoobymania, in Nottingham. www.scoobymania.co.uk.
VERY helpful guys, the pod was £80, and fits like a dream. They even marked the hole centres for cutting once they knew which size Defis I wanted.
Only prob I had was cutting holes in it: I forgot it contained fibreglass, did it in a sleeveless shirt, and was itching for 2 days!!!:
