I've used pick a part in Campellfield before and they were pretty reasonable, got an EDIS module, leads and coil for ~$30 (I also got 2 suitable replacement alternators from a Daihatsu and a Swift for I think ~$25 to $30 each). Not sure if they had any suitable Commondoors there though? What year do you use GT mowog?

They have a website listing vehicles in the lot (at both sites):
http://www.pick-a-part.com.au/parts_recovery.php

There could well be somewhere closer for you though.

Thanks David, I might just take a drive out to Campellfield tomorrow... one of my neighbours said the wreckers here in Werribee are a rip-off... it would be a good little drive for the Mini!

One advantage I think is that the Bosch sensors are designed to mount using a bolt that goes through them, this means that they can be attached to existing bolts such as the bolt that holds the alternator on.

Jim ... sorry for hijacking this thread! :oops:

I don't actually look to see what year, only if it has an in-tact knock sensor.

So is the theory that if there is a knock you advance the timing?

Other way.

Not advance, retard! The megasquirt would receive a signal from the knock ECU, and will send signal to MS ECU which will act on it dependant on how its been setup... usually retarding spark by a set amount for each knock event it receives.

Theoretically if you have had your engine on a dyno and had your ignition timing mapped correctly, a knock sensor is a bit of extra fluff, but if you're broke a knock sensor could also save your engine especially at higher revs (read louder engine noise) when you cant hear pinging/knocking.

Could somebody break down whats just been said for those less initiated (like me :oops:

) These systems are designed to manage the engine electronically? Is this essentially an electronic fuel system negating the need for traditional carbs and that setup. What are the advantages?

Sorry I dont completely understand how they work and was hopng to gain further insight :wink:

No problems.

That's a very well priced kit really... If you had to gather all that stuff up yourself, even if you could make some of it, it would surely match the price?

What I am wondering is why you would inject a 5 port siamese head?
What advantage is there really?

Also, knock sensor and MJ work... retard timing through the MJ

Only thing is it cant control your injector/throttle body setup really.

If it was 7 or 8 port injected - ooh yeah

Not being a smart a$$ - genuinely asking why you would inject a 5 port head.

Having said that, trying to work out what mods needed for a turbo setup with this injection, etc.

Cheers,
Peter

I guess there is no advantage to a carb with the perfect needle.

Ahh 'a perfect needle', sounds like something you would send the apprentice to get, like a L/H hammer or a can of striped paint. :lol:

Pick 1 needle out of 800? You might get lucky... but you might never know it. :lol:

Why I prefer Dellortos and Webers. You can tune the suckers easier.
