Hi folks.
Just finished doing an efi conversion on a friends S1 using an ofab ecu.

The guy who owns the car came to see me for a bit of advice, cause he wanted to do as much work as poss himself.

He wanted to install the CKP himself. This is where I made a fundamental fook up

Never told him to drill it at the right position in relation to tdc.

I wired it up and got it running after a few teething probs and horribly corroded earth wires.

To cut a long story long, I am worried the ign timing might be well out.
Is it possible, when mapping, they can find where the base/ static timing is at and use this as the control to advance or retard the ign to get the correct setting.

So for example if it is idling, with vacuum advance off at only 6deg, could a tuner put an extra six on and obviosly a factor of 6 up the whole map.

And if this was possible, what would happen if there was a problem and it fell in to LOS mode, or does mapping erase this function anyway.

Sorry if this is 100% bollocks what I have written, but I don't really understand it yet, and sorry for going on too,

Story over, cheers.

 

If I have understood correctly and depending on the management used, you can read the timing off the front pulley with a strobe, then tie that up with the management.

 

Right, so no need to panic just yet!

Will check it with a strobe on the weekend to see how far we're out.

I guess it will then be a case to see if it is possible to alter the settings using fiesta turbo management.,

What a dick head I am

 

do you mean the cps?

 

Yes, sorry.

 

if its been drillled into the block where it would normally go on a efi car to face inside the flywheel

as long as your using a efi flywheel and its sort of central to the pick uppoints you will be fine

as the flywheel will only go on one way round

 

Yeah, I think that's where I might have a problem.
Never timed up the true postion in relation to top dead centre.

Car runs ok, just not sure untill I get hold of a strobe, where the ign timing is at.

Are we buggerd if it is too far advanced or retarded?

 

i wouldnt of thought it woud of matter but no thinking about it i can see your point

i was under the impression that as long as it see a 32-1 i think then it will be fine

but now as you say if its in the wrong postion it could be out

sorry carnt be anymore help than that im afraid

as its got me confused now

 

Cheers bud.

Got me in a right state too.

But you get where i'm coming from, which means I'm not going mad.

 

you'll have to pay like 500 quid to get that mapped though as theres virtually nobody who can map it so they charge what they want. Would be cheaper to get a FRST block
