Hi
Anyone here have experience with converting a 1979 VW Beetle fitted the bosch injection system and the black box behind the back seat to carbs?

Why do you want to take a step backwards?


Escarabajo - February 24th, 2008 at 01:13 PM

its what do you do when the "black box" goes wrong?


11CAB - February 24th, 2008 at 01:25 PM

What I'm getting at is how do you know the "Black Box" is broken? What is the problem? You should be able to get it fixed, and it will be better than carbs

Well I think you will have people lining up for your FI hardware, me included!
From what you are saying, it isn't broken yet and this is a "what if". If the worst happens get it fixed or go aftermarket ECU but KEEP your FI

Why why why ???????????????????????


I'll b in line for your hardware too!

I believe that a Camira computer will do the job for the US injection system.

nuy an after market ECU even a second hand Micotek will only cost 4 to5 hundred and wire it up


Or byt the latest Autronic for about 16 or 17hundred

You will lose a lot of power if you go to carbs..
as the valves in the Fuel injected beetles are much smaller than the carburetored engines...

so you would need carby type heads....

the fuel injection engines were very different to the carby models..
tinware etc...
best of luck

What's the problem? Those old 'black boxes' seem to go forever...

You won't lose much power - they don't have much to begin with! - but the EFI is a lovely smooth torquey vehicle to drive and you will lose that

I have an EFI Beetle same as yours and have had only minor problems with it - all hardware related (ie loose/perished vacuum lines, spark plug leads) rather than the electronics

As Glenn said, you will certainly miss the torgue that the EFI brings. I'd diagnose first before pulling it all out. Keep in mind that your heater boxes and exhaust system are totally different too. Once you fiddle with one thing, who knows what else you'll have to change.

Thanks guts
Gotta get the car into the country first.............

Cool - I was concerned about getting info on this system when I bought mine, but got most of the diagnostics info etc I needed (was reading just for interest/knowledge) from the net; someone had scanned in the service manual and posted it on SuperBeetles Only.com, I think

It is a dead simple system to work with
