Title: Ignition set up
Post by: maximous on 25 July 2005, 13:09

Hi everyone wonder if you guys can help. A friend and me have taken a mk2 driver and put a 1.8 16v on twin carbs, and we are having some trouble at the rolling road stage. It runs lite poo and is producing too many hydro carbons. the compression test is all good and i was wondering if it could be a ignition thing or the set up i have on it.

It has the standard driver ecu on it with the 16v dizzy; would this be OK. Failing that what else should i look at using

Dunno if it helps but the 16v should be set to 5 to 7° BTDC at 950 to 1050 rpm, with vacuum hose connected.  Don't ask me which vacuum hose though :grin:

Thinking about it, how are you controlling the Dizzy advance, isn't it controlled by the ECU on a 16v?

I would of thought that you would need to put the ecu for the 1.8 16v on and not the driver one.
Its the engine your changing so you need all of the assosiated components i would of thought. it must of run ok when it was in its original car.
If you change the ecu its one more variable taken out and then things will point to timming and carb set up.

Not too sure i just assumed that like other Dizzys the advance comes from the dizzy not the ecu. I have the 16v ecu in the garage but it doesn't really help as the car is still at the rolling road. Just told him and he didn't seem to concirned and said thier working on it now to see what they can get out of it.

Propper confused now.

how hard is it to replace the driver ecu for the 16v one, is it a case of un plug and replug?

i would of thought so  :undecided:

if you have used the driver loom to wire the engine in i would of thought that it should be the same connector but then again sods law could come in and the connector could be completly different  :laugh:

yeah watch out for sods law he pops up a lot :rolleyes:

you need the 16v ignition system. there is an ECU temp sender (blue & white wire) that the 16v uses (plugs into the side of the head with the ISV & dash temp gauge) so that the ECU know's how far it can advance

Thanks for all the advise guys. Do you lot know anywhere around Berkshire that could set up this thing as Clifford Cox would be deer and I'm not that good with wiring.

Thanks alot max

I would look into using a 1.3 polo or similar distributer as this has the advance mechanism inside.
