timing help:-( help needed badly now as the thing just wont time up

[youngprodigys]

all my sensors are correct. it was running on my eaton charger. and i did my own custom loom
so i know the wires are perfect pin to pin.

map is what came with the kit- im starting to think this could have the issues. ive took it out for a drive and it runs ok ish, hunts like hell when i pull up to stop but acceleration is ok if a bit lumpy.
actuator cuts boost at 5psi at the minute so no chance of detonation:-) mr forge actuator should be here soon!

Hmmm..is there any identification to the map...any indication if it's targeted at your spec or something very close?

[youngprodigys]

its got tom k03 250cc on it.

[cheys03]

its ridiculous it really is- i set the timing with the gun with the blue temperature sender unplugged (revs rise) and get it pretty good, then as soon as it is plugged back in it goes miles out when i point the timing gun at it.

surely thats not normal?

I've just had a thought... The ECU will manage idle speed by advancing/retarding the ignition timing - so what you're observing could well be perfectly normal.

[youngprodigys]

yer but when i rev it to about 3k its a good inch out! so that like 25/30 degrees!
i think i really need another car against mine to check it against really to see whats different and what it should be doing.

It's normal for the timing to jump around massively one the bts is plugged back in. As Chris rightly said, that's how the ECU controls trhe idle speed. If the revs are gunting around with the timing set, then I'd be checking idle speed settings. If idle speed is way too high or too low, or there's a sticking throttle or other air leak, the ECU will not be able to stabilise the idle with ignition timing alone - it'll have a bloody good go though, which is why the revs will hunt around.

I'm still away at the moment dude - are you going to Actiobn at the weekend? If so I can have a look there. Also be worth finding out where that chip came from so you know what spec it's for.

[youngprodigys]

idles at 800/900revs. i dont think theres an air leak as the idle screw is pretty responsive.
im at edition not action. going to try setting the timing at 3k and getting someone to help (so its not on idle switch) take it for a drive and see. what my mate suggests is dialling in 10degrees advance and seeing what it does and then 9,8,7 etc and see how it runs.

will lambda position make a difference? ie on downpipe rather than original position behind the engine?

[youngprodigys]

oh, and my plugs are brown on the ends = bad timing

[youngprodigys]

problem solved. engines throw a valve. pretty mad how it still does 70mph and quick of the light when it has 3 cylinders:-S

[grungeisdead]

=[ gaaaaaaay

[youngprodigys]

me and guy (mclovin) have smashed it and fitted a new cylinder head. all is cock on and running mint:-) only the fact that the forge actuator i have isnt correct is stopping me from full boostings.
weird really - the actuator rod isnt long enough to fit. yet the bracket is perfect.

[cheys03]

Outstanding!
Actuator rod sounds a weird one. Any pics of it fitted?

[youngprodigys]

cant fit it:-( rod isnt long enough and the threads wrong. bracket is a passat/A4 bracket and has the correct part number on the box:-( ive called forge about it as it was brand new.

rod length is 97mm and full extended is 110mm- not long enough!!!

[ereeiz]

Good to hear you got it sorted mate

[PeteG40]

why did it throw a valve???
