[Mk2] [Turbo] Car trouble. Idles but any revs, just cuts out and dies? *UPDATE*

[JJ]

ive just thought tho, if im replacing the dizzy, surely im not going to fit it 100% in the same position?? so going to have to get remapped??

Mark it up before you remove it you barn door !!

All distributers will fit for the record.. this includes normally aspirated !

It works with the standard ECU as when g1 drops out it reverts to G2 which the powerfc doesn't do

Good information Ryan... Why only £5 ??!!

just watch out for the oil pressure sensor at the side of the dizzy. I snapped mine clean in half when my hand slipped another 25quid to Toyota

You did that by slipping ??!! What are you, 20 stone or sommat with iron fists ?!!

[jimGTS]

oh sure would try and mark it up, but you can never be 100% surely....
still i guess half a degree or so out wont course a great deal of harm im sure.
hense why i said 100% same position


yeh ive had one off before on my rev2 when i was doing the headgasket.

i guess advisable to get the dizzy o ring that fits to the end of the camshaft.
apart from that, pretty straight forward swap.

yeh i know where the oil pressure sensor is, no idea how you snapped that thing off with your bare hands unless you lent on it, lol.

nah, my dizzy had never been moved since day one and I had to remove it a dizzy cap bolt had sheared. Was wiggling the dizzy body to remove it and er as I twisted my hands slipped - bang splat. Broke the plastic clean off the end of the oil sensor

He meant to just check / change your Distributer cap didnt he??? if so Its just the Dizzy cap you need to remove not the whole unit. The actaul Distributer doesnt move when you change the cap does it. Just undo the bolts holding the cap on and pop a new cap on. Probably do the rotor arm thing as well while your at it 5 min job

[jimGTS]

im pretty dam sure there refering to the whole dizzy.
not the cap.

i dont see how a dodgy cap could create my sort of problems!

[jimGTS]

Well I've purchased a whole dizzy unit anyway, lol.
got a rev3 turbo one arriving off gtschris. Hopefully that turns up today and I can test it tomorrow.

Tho looking at the bgb, Ryan is it possible to test my present one is broken and that the new one is ok with a mulitimeter before I pop it on??
Or could it be within bgb spec but still broken/won't work with the fc???

[jimGTS]

New dizzy on and there's no difference.

Pretty sure it's missing on 1 cylinder.
Rev3 ecu, starts and revs fine with the new dizzy. No missing.

Power fc, can still idle, I could rev a little, but it was like it wasn't sensing the throttle, if I wotted, there would be a big pause and almost die. Can rev slightly, but missing.

Going to find out the spark and which if any cylinder is missing.

£5 on it being the Dizzy

The Powerfc uses the Crank signal from NE and the cam signal from G1. All issues i have seen like this with the powerfc have been due to issues with the G1 Reluctor pickup.

It works with the standard ECU as when g1 drops out it reverts to G2 which the powerfc doesn't do

Thought i would post in here Jim to help others in future.

Ryan

Is the signal for G1 & G2 the same.

i.e just a wire swap will cure the problem?

If that is the case all Jim would need to do would be to swap the wire from G1 to the G2 signal input for his PFC.

[jimGTS]

checked the spark with the powerFC on the leads, and appears im getting a good spark on all 4 cylinders..
tho it definatly sounds like its missing when running on it and trying to give it a bit of revs....

so guess its not firing the injectors???
sorry i dont know i great deal about these things


vids to follow

[jimGTS]

oh and i checked both the dizzys resistance wise on the plugs, and both were within spec...
tho i couldnt check the gaps as per the bgb.
but reisstance was correct on both.

(this is on the new/spare dizzy)


powerFC
literally any throttle, and its dieing....





rev3 ecu
(weird buzz in the video, ignore that) but the last few seconds you can clearly make out a nice running car when revving)

can anyone confirm this is safe for me to do????

to anyone;
if it was a g1/g2 problem, how comes the new dizzy hasnt sorted it???
still its not the most expensive or hardest thing to swap out. but waste of £45 at the mo.

[Lewis Jay]

If you can work out which ones are G1 and G2 then you can test them.

Dont see whay it would be unsafe Jim, as said before by Ryan, the stock ECU switches to the G2 pick-up if G1 fails.


On another not though, as you said a different dizzy has not fixed the issue so maybe its the PFC itself.

Lewis.

[Steve-O 2007]

im pretty dam sure there refering to the whole dizzy.
not the cap.

Im going to go sit in the corner now and play with my stockish car and leave this to the big power boys then


what about your earth points under the inlet manifold? Maybe the PowerFC requires stronger / better earths than the stock ecu? When my Earth wasnt good on the bottom of the manifold the car would start and then cut out or start rev it and it would sound rough and then cut out.

[jimGTS]

Manifold grounds are good as the weekend I removed the manifold to clean and spray. Ground point defo good



Lewis i just want to confirm with Ryan it's ok to swap the pins at the ecu before I go ahead. Him being an ecu guru and all. Have seen the pins on the gen3 ecu diagrams online and there right next to each other. So should be easy to swap around.
My only concern before doing it is if the g1/G2 input runs other things as well as the dizzy.


Anyway, now I've tested that dizzy, and asuming swapping g1/G2 is now meaningless.

Where and what do I do now????



Cheers

[jimGTS]

bump from this morning.

[Quigonjay]

do you know of anyone with another pfc that you could swap to try out?
