HI all, first post on here so be gentle!

I have just dropped a rebuilt and slightly modded Gti-6 engine from a Phase 2 (S-reg) into my '51 Cabriolet (phase 3)
I bought the whole Gti-6 as a running car, it is sat next to the cabriolet now, so I have all parts available from both.
The cabriolet has a DEI/Viper remote start full top of the range alarm system with it's own immobiliser, so currently mine is bypassed by having the transponder glued in the ignition barrel.

From what I have read elsewhere, I should be able to put the whole Gti-6 engine, loom and ECU in the cab, along with the gti-6 immobiliser and antenna, then glue the gti-6 transponder chip in the barrel to bypass the immobiliser and let my 3rd party alarm do the immobilising.

However when taking out the Cabriolet's immobilser to plug in the Gti-6 one, I notice it is very different - the cab one is about 4 times the size of the Gti-6 one and has 2 plugs both with more pins!

So, err, how do I go about this?

Will my, I believe, standard Gti-6 ECU work without an immobiliser being connected (as the plugs are very different)? Do I need to splice the two immobiliser looms together somehow? Or do I need to get my Gti-6 ECU unlocked / buy one already unlocked and just miss out the whole immobiliser circuit and bits?

Is there anything else the immobiliser unit/box does that I shol dbe concerned about if removing it altogether?

Thanks in advance of your wisdom

Ahhh a man after my own heart

pretty much explains it I think.

I went the route of a complete aftermarket mongoose system to control immobilizer alarm and c/l

Welcome. Good luck with this problem.

Get some pictures up?

Oh here's one of the engine during the rebuild and paint/lacquer etc:


Engine painted Chine blue, sump & ancilliaries painted satin black, cam covers and inlet manifold mirror polished then lacquered with a hint of china blue - looking good I think

Yup, but not for the 306 Cabriolet - as far as I know no-one does one for the 306 cab
It is not a complex computerised input, just an up & down switch - but because the European regulations state a convertible roof cannot just operate on it's own without having safety measures built in, which the 306 cabriolet doesn't, it has to remain a switch that you have to hold up or down for the duration of the roof cycle - makes sense kinda, for example; kid gets finger stuck in it, screams, so you let go!
With a one-touch it would carry on and you might be out of the car, so can't reach it to stop, and even then how do you stop it? thus A&E is your next destination

Anyway, just 2 timer circuits in-line will do it, with a stop if you press the opposite switch- built one up already, just got to make it plug and play next (so no need to splice loom), then maybe make a few... for some reason they seem to be in demand yet no-one has done it

Not just European Regs, Australian design rules also require it, not sure on the US though.

I take it you just used a cpl of 555N timers? if you add some load sensitive resistors in the circuit you can monitor the motor load and use that as the "Finger off" safety.......... just thinking

or for an ultra simplistic one
change the switch for something other than momentary action

although I'm now going to go pull a roof ecu to pieces just to see what can be done

Had a few head scratching moments working out which sockets on the engine loom went to which switch/sensor!

On the Gti-6 radiator I have a 4 pin plug on the rear of it on the passenger side. I have the same on my cabriolet radiator. Yet we cannot find something to plug into it from either cars loom, engine bay or the fan housing. What is it for and is there supposed to be something connected to it?
On a friends cab he has a plug connected to it, the cable disappears into the fan housing (he has no aircon and only one fan on his car)

Anyway, much thanks to richW the unlocked ECU arrived, a few more bits were replaced (again!), and then she lives:
