G40 ECU controlling fuelling only

Would it not be possible to modify the G40 dizzy to work on the mech head (or visa versa)?

Saab distributors fit, but they have mechanical and vac advance, could lock it off and play about with it?

I remember a mk2 Golf with a 1.3 (non charged) engine in golf + or performance vw mag when I bought mags (so approx 5-10 years ago). I remember it revving to 10k rpm or something, was done more as an exercise than anything else. May be worth looking that up and seeing what he used? I also remember someone on here (or PSD forum when it was alive) that did a lot of work / info on valves/ lifters, speeds / ratings, etc. Can't remember much more than that.

That golf sounds interesting, any more info I could use to search for it. Fast Golf is likely to bring back a lot of results

@Eric - what would be the benefit of using a Saab one though? If it's not compatible with the ECU then I'm in the same position as using the standard one

I just had a look, can't find anything. It was (almost 100%) in either Golf + magazine (I think it had a different name prior to this so may be in there) or Performance VW magazine. I would say it was around 2005- 2007, I think it was the cover car, although can't say for sure. I also can't remember colour of the car, green I think? I just remember it had a lot of work on the engine with the idea being to take the n/a 1.3 engine as far as he could. Unsure if it was a UK car, I think it was though. Sorry I can't offer much more help than that! Perhaps if someone has back issues they could take a look, sure it would only take 15mins if there's a stack of mags.

because it uses a hall sender instead of points. people use them to convert a mechy engined mk2 to electronic ignition, so you may be able to use one

Really? That might work.

I've also looked at the amethyst conversion at that can be used for boost and I can keep the old dizzy

Yee from a saab 9000 or something

The old system Porsche engined Seat Ibizas also had an electronic distributor that fits the mechanical heads too, but as already mentioned, you'll need to lock the baseplate to stop it advancing/retarding on it's own.
