Bosch KE-Jetronic convertion to EFI332...possible?

[Gerard]

Hi!

I'm interested in getting a better more efficient fuel system for
my vehicle. It is a 1990 Audi Turbo (known as the 200 in the USA).
It is a 5-cylinder 2.2 litre 3-speed automatic front-wheel drive
machine. From the Haynes books I see they indicate the fuel system
to be a Bosch KE-Jetronic system. It is still mechanical and uses
constant feed injectors. The ignition system is fully electronic
and uses a Hitachi unit (with a mass of pins!) to mimick the workings
of a real distributor.

I get about 12.5 litres/100km out of this thing in town driving and
about 10.5 on the highway (at about 150km/h). I've been looking at
rechipping the thing, but all that can be re-chipped is the ignition
system since the fuel injection is still mechanical.

So anyway, the nicest thing to do would be to convert the entire
fuel injection system to electronics (EFI) and then program it.
The EFI machines have better consumption and still beat the mechanicals
for power and drivability. Also, having it in EFI form would be nice
if I decide in future to introduce nitrous-oxide, that way the mixtures
and timing and be altered dynamically for the best use of the NO.

So, I'm on to this EFI332 system now thanks to one of the members of
this mailing list. And, although I've just become prime bait for
flaming, I find it necessary to send this sort of message to the
list in order for me not to waste a lot of time only to find out the
EFI332 is the wrong choice for my system. In this regard I have some
questions for the members of this mailing list:

	1. Anybody done a Bosch KE-Jetronic conversion to EFI332?
	2. Anybody done a conversion to an Audi?
	3. What sort of workload is involved in KE-EFI332 conversion?
	4. Can an idiot computer scientist like myself easily get to
	   grips with this system?
	5. How easy would it be to dyno-tune this EFI332? I intend
	   fitting a variable fuel rate / fuel pressure fuel pump.
	6. Can the system (the ignition system) cope with fancy things
	   like Nology HotWires and Silverstone spark plugs?

If anyone has done a Bosch KE-Jetronic conversion then I'd like to
hear about your project. :)

Just a note, this turbo has almost everything monitored that I think
would be necessary to convert. Also has 2 knock sensors and a turbo
boost pressure monitor (well, if it displays boost electronically while
I drive, then I assume it has a monitor on the turbo).

The more I look at the EFI332 system the more I like it. It beats
blowing US$500 on a rechipping of my electronic ignition unit only to
get some 10kW more power.

Hope to hear from someone on these topics...

Thanks.
