Engine Management (Not R related)

Ok, if you had an engine........in this case a 1.8T Golf engine.

You want to make the engine run in a different car.......in this case a Mk1 Golf.

The ECU for a Mk4 Golf has an Immobiliser which make's it expensive to get running, so you used an modified loom off another car, say a Bosch Motronic system out from a Vauxhall or Peugeot as both sytems use a MAP sensor.

I cant see why this cant be done, as at the end of the day. All you need is a MAP or Airflow sensor, 4 injectors and a lamda sensor. (In theory)

Oh, and the Bosch Motronic systems have a limp home mode which can be mapped.Not R related,moved to tuning-skiddusmarkus

I'd appreciate any input on this.

As long as you can map it, don't think the map for a Vauxhall engine etc.. will work properly on a VAG unit, especially n/a to blown, and bring the sensors over with the management system, can't see why it wouldn't work. :D

I see your theory and it may work if you can map the bosch motronic accordingly, but a after market ECU would be easier to map and set up than a complicated bosch one, and some mappers may prefer a speceifc ECU rather than try and make a bosch one work. When i put a Carbs on my zetec in my mk1 escort, to make the sparks i used a EEC4 brain and loom and just didn't connect up the injection part of the loom, BUT last year or so i put throttle bodies etc etc on my Escort and i have used the OMEX 500 ECU easy to map yourself and play with, it uses all the above sensors and you can communicate and play yourself which saves loadsa money on the rollers until your ready for a final check. I mapped mine myself. 8)

Apparently in CCC the Pug loom and ECU is a common use even on TB Engines.

It is a cost thing ya see, aftermarket ECU is a deffinate thing for a later date but on top of the engine it makes a 1000 quid project into a 2000 project.

If anyone has a CCC that mentions this method can they have a read again for me.

First off is the mk IV scrap and do you have the keys ???

i would take the mk IV loom and transfer it ( ecu related ) into your project car, and convert to mk IV steering column to allow key operation. especially as the turbo unit uses individual pencil coils with NO distributor and i think also a phase sensor for sequential injection, also unsure where the tdc signal originates- either phonic wheel , machined crank or flywheel.

failing that how about a cossie loom or RST fiesta eith chip and injectors

if modifying will need to confirm tdc sensor position in relation to tdc of no 1 piston and ensure firing order 1342 etc

I work for a vw dealer and aparently when doing the conversion youre talking about you just need to take out part of the dash pod and use that to get it running. Ill try and find out more on mon :D You could also try one of the dub forums theres a lot of 20v t conversions about at the moment.

Yeah, there are loads of conversions done, some people have been using the full loom and just taping the key to the immobiliser ring under the dash, some people are just using DTA which is plug and play BUT is a grand.

There are a couple of people using the Pug system but havnt given much details. Using the Pug system is common in rally cars, race cars etc.

I'm not in the UK you see, so cant compare anything. Just running ideas around in my head, i have enough project's on the Go even when i do get back.

Also, it is dirt cheap to buy em as a lump without electrics etc, As soon
