My kind of modded car

I suppose it might work if you also fitted the electric windows, full dash, climate / aircon blah, blah, blah.

See the problem..... the ECU pretty much controls everything and throws a fit if something is missing.

Even aftermarket ICE causes issues, and many VW dealers insist aftermarket headunits are removed before they'll hook up their VAG computer to the car due to issues with the proprietory wiring scheme.

Take everything out. Fit the stuff that will fit to a MkI shell, dump the rest in the boot and hook it up to the loom.

Very practical.

Read up about the subject _properly_ before making such totally fuckwitted statements.

No it's not.

The best option, by far, when making engine transplants is to either leave the donor ECU behind and switch to custom ECU or work out how to hook up the new engine to the old ECU.

ClubCento memebers tried both options when switching Punto lumps into the Cento, and found the best / easiest option was to keep the original ECU as it means _much_ less faffing with immobiliser components.

IIRC neither 1.9 Mi16's or 205 GTi's had immobilisers, so that wouldn't be a problem :) The beauty of that particular swop is that they're virtually the same ECU any way, so you can leave the original in if you like, but if you put the new one in, it works easily and is better.

Yes it is. You already have everything required in the donor car. Why would you NOT use it ?!?!

Quite obviously it's easier to use all the standard stuff that comes with the engine in the donor car !

Why would you be faffing with immobiliser components ? You'd have taken them with you from the donor car !

As I said, it's gonna be easier to use *everything* from the donor car. If the engine needs the immobiliser gubbins, then swap it over. Obviously if you're gonna miss things out, then you're gonna have to perform "faffing with immobiliser components" !

Exactly.

Surely it's trivial to spoof the windows etc. - the odd resistor in the appropriate place, and the ECU will never know it's missing. Anyone attempting a job on the scale of transplanting a completely different engine from a completely different car, is gonna have no trouble paying an auto-sparks to sort out some bits and bobs. He's already gonna be getting custom mounts, driveshafts, etc. etc. made !

You don't need to hook everything up to the loom - you merely need to make the ECU *think* that everything's hooked up. This can be as simple as sticking a few resistors around the place, or as easy as connecting the teeny control boxes from each component etc.

Certainly a bunch more practical than pissing about spending vast sums of cash on some aftermarket ECU setup :)

Perhaps you should also try ? As Depresion has already stated, it's been done, in the real world !

Clearly you can only keep the original ECU if you *can* actually keep the original ECU !

Good luck getting a 1.8t lump to run with the, er, "ECU" from a Mk1 Golf !

There's a real world?

Its a patch for Windows.

But it's not exactly stable, I find it keeps going light/dark/light/dark it cycles like this about 7 times a week. I also get some vertex tearing resulting in white partials all over the place at the moment.

All sounds a bit strange. Think I'll pass on that one.

And tell me exactly how you'd fit all that kit from, say, a MkIV Golf into a MkI or II?

You _really_ don't understand the whole concept of integrated ECUs.

If you search around the 'net, you'll find that the only 1.8T transplants that have been done have involved junking the original ECU and going with a custom made unit and loom.

I'd suggest you do a bit more research into swapping engines and ECUs from modern cars into older ones before you make more of a fool of yourself.

In the case of 'cento engine swaps you needed the original keys, lock barrels, fuel pump, ECU, transponder sensors etc. Much easier to hook up the engine to the original ECU, or start from scratch with one designed for such a swap.

In the case of the 1.8T engine swaps there's further complications from drive by wire throttles etc.

Fudging resistors into the loom to 'emulate' climate, windows and all the other bits and bobs isn't something you'd want to get into as it would take more time than it's worth.

Not all of the 1.8T's are drive by wire just like the V5's.

Preferably with a TT dash as they look the dogs in a Mk2 golf.

Well, yes, it depends on the year. Mine missed out by 12 months.

However, all the rest is true, and the recommended route is the custom ECU so you don't have to piss about trying to convince the original ECU that everything that should be there is there.

The same sort of way you're fitting the engine in there !

Wa ?

Are you suggesting that you CAN get a 1.8t lump to run with the none-existant ECU from a Mk1 Golf ?

Did you even read my post ?
