Have you checked your fuel pressure? I don't know what it is supposed to be but
the pressures should be listed in you manual.do you have a fuel pump relay?That
is also a possibility.
I would think that with the sensors that are on that engine the megasquirt
should be easy to install.You will probably have to install a TPS a mat sensor
.It probably has a MAP sensor some where ,you might want to check that.You
could have a electrical breakdown due to the heat from a long trip.Can you
duplicate the problem with out doing the long trip thing.generally a temp
sensor will not cause a cutting out condition.It will make things rich or lean.
The Sciroccos seem to have lots of fuel pump problems but most of them are
high psi systems (110psi)I don't think yours will be that high probably around
43 psi
I think the Megasquirt would be relatively easy to install on the Vanagon.Most
of the sensors and injectors are Bosch and that is compatible with the
Megasquirt system.You probably would want to use a heated narrow band 02 sensor
as it will give you better information.I have installed a wideband 02 sensor
with a controller and a digital air fuel ratio gauge on the dash.It allows a
much finer
Mixture adjustment but it certainly is not required.If you do decide to
Megasquirt you might want to consider the megaview.It is a 45 second scroll of
engine information ,some of which is really handy.You can also use it to change
the mixture from the cockpit but it is not recommended for obvious reasons.

Hi Chuck,
My 84 vanagon has the original 1.9 liter, fuel injected, watercooled
"wasserboxer" engine. it is the digijet fuel injection system with a single
wire O2 sensor, 2 temp sensors (one for the ecu, one for the temp guage) no
power steering, no functioning air conditioning (altho the compressor is there)
and manual transmission. I have been having problems with the vanagon cutting
out and loss of power while on long road trips. I have recently replaced the
air flow meter, cleaned all the ground connections, changed ignition coils,
checked the injectors, the catalytic converter and the muffler are both fairly
new. I might have a bad temp sensor from what I was checking last weekend, but
I'm not sure. haven't been able to find my volt meter yet. any advice you could
give would be greatly appreciated.
Thanks, Mark

Well, I don't know anything about computers,fuel injection systems,or
building circuit boards.I don't type either so everything is an adventure.I was
still able to build the V2.2 megasquirt FI controller and make it work.It's not
rocket science.You just have to be able to read and follow directions.It's also
nice if you are able to solder.If you don't know how many cylinders your engine
has you probably shouldn't attempt the build
What type of fuel injection system is mark running?I assume it is on a
air cooled engine but I don't know.If some one would contact me with all of the
information I might have some suggestions.Megasquirt can be put on anything
that has a gas engine and be made to run.
Does the engine have electronic FI now or is it a cis system.inquiring
minds want to know? If it has elect.injectors the installation is much
easier.If you want to use the squirt to controll Ignition that is also possible
.I didn't want to attempt that because I wanted it to be as simple as
possible.I went strictly by the book because it didn't require as much decision
making as to which part might be substituted. All of the needed components are
discussed in detail.
When I built mine there wasn't any phone numbers to call so I had to
learn to sorta use the computer to get information.It's still slow and an
adventure. http://www.bgsoflex.com/megasquirt.html or http://www.msefi.com/
both have lots of information read everything that you can find.If anyone is
serious about building a system print everything and start a book.Everything
that you need to know is available on their web sites and forums.
If marks FI system has been in use for 22 years it probably is not to bad
of a system.It may just need someone to do a little stroking in the right spots
sensors and things need to be checked along with connections and wiring and
such.
Here are a couple of numbers where I can be contacted 903 221 0434 (temp
number)or 903 312 5257 cell numbers.If I have to do this via a list you might
as well set it on fire because it will never get done.
If I knew what the symptoms were and what kind of engine we are discussing
I might be able to give a little more information.Regardless as to what Denis
might think, I am not a mechanic but I do know quite a bit about cars,having
worked around cars, engines and mechanics most of my life.
I'll be glad to help out If I can.
Man, all this typing ain't fuckin easy.

Hi Chuck!
Mark is continuing to have problems with his stock FI.
I forwarded him these mails I got on the type 2 list.
We (he,I and another friend of his) are thinking maybe mega squirt could
be a solution.
What do you think?
Can you provide us with some good places to look on the net?
Thanks!

Not a word from Chuck or anybody else about fuel injection. I was doing
some testing the other night and thing that I have a bad temp sensor. I would
still like to invest in a system that would be more reliable than a 22 year old
and outdated injection. I just don't know enough about computers to even know
where to start. I am going to go get my spare engine out of the store room this
weekend and start getting ready it ready to install. I think the engine that is
in the vanagon now is starting to knock a little more than it use to, or I
could just be getting paranoid.

Denis and I also know the Dave Bolen listed in these e mail from the

Dave is in the VW club Denis is in now, he lives in Fayetteville, Ar..
I know not a lot of hope for hands on help but I think you and Mark
and I could pull it off with Dave and Chucks help.
See what you think and I will see if we can figure some way to
commucate.
I may foeward this to them to get their opinions soon.

Hello list, I am making slow progress installing a new Megasquirt
injection system on the bus and could use a leg up from the guys who have done
this on the same engine.
I am using MS-II, V3.0 board, fuel only until I get everything
running well, then ignition control as well.
I cannot get it to idle, and only runs when I advance the ignition
a lot.
I would love to get your .msq and VE tables if you have arrived at
a tuning set-up that you are happy with. Are you running the original low
impedance injectors? with PWM or resistors?
Thanks very much. I will take this off list now, I just wanted to
contact the VW guys on megasquirt as directly as I could.

Ok,
So here is what I sent back this morning....not megasquirt V3, but
an
earlier version....with pics...in a camper.
Ed's site is still up and should provide you with the numbers you
need.
Compare pressures and injectors and go from there.
Great pics also!

I'd like to follow this as well. While I have no need to mess
with the FI in
the Guac, it's something I've always been interested in.
Me too.

Don,
Let's see if I can remember....
Depends on how far you want to take it....
No AFM box.(lose the intake restriction.) MS uses a throttle
position
sensor.
No stock ECU box. Use MS ECU
No double relay. Use MS Relay package.
If you want, you can loose the resistors for the
injectors....although
it may be a more robust system if you leave them.
Lose the stock temperature sensor. Use the GM replacement in the
air
stream.
I may have missed something along the way.
The good/bad news.......
You have complete contol over the ECU, which means you can program
pretty much everything....the bad news is the same....you can do
harm to
your engine by programming it to not inject enough gas at high
speed.
Of course, you can do that with a carb as well if you try....
Go here to learn more.

That is beautiful. Absolutely beautiful.
Now, what is the benefit for a stock configuration to using MS as
opposed to
the stock computer?

Another alternative for those who have less time and more money:
http://www.sdsefi.com
I think that Jake Raby is using the SDS unit on his type 4 engines.
Lots of info, including complete manuals, on that site.

Subject: [T2] Re: Megasquirt on 82 Vanagon
Thanks for the interest. I will eventually get pictures and a story
up on my website.
Benefits to me:
Well, my existing stock setup was giving me a new problem to deal
with every couple of months. This was attributable to 24 year old wiring being
heat damaged so it snapped instead of flexed when bent. Also the ECU was
flaky, verified by swapping with a federal ECU which ran poorly, but had
different issues than the original California one. I just recently opened up
the Cal. ECU and was surprised by the amount of corrosion which had crept
inside it, but no surprise it was flaky after seeing that. By the way, I was
going to try and salvage and use the injector resistors which I thought were
built into the ECU (not external on this model), but could not find them.
Perhaps Bosch used some sort of pulse width modulation (PWM) to control the
current on the stock unit? The resistors should be big and obvious if they
were part of the circuit.
Right, back to the benefits... I would have had to rebuild the
wiring harness almost from scratch to do it right (no-one supplies rebuilt FI
harnesses AFAIK), and find another old ECU which worked reliably (or paid the
big bucks for the rebuild if available). The alternative I chose was the
Megasquirt.
Advantages:
- have the fun of building it (sort of like the fun of building a
model airplane kit, but more of it)
- Learn something about fuel injection and engine tuning in fair
depth
- simplify the whole system hardware-wise >> eliminate the AFM,
coldstart valve, thermotime switch, double relay, decel valve. I also got rid
of the digital ignition set-up except for my hall-effect distributor.
- Gain a new modern fuel injection system which is totally user
programmable (or self-tuning to an extent), for at least as good as like-new
performance. I had just rebuilt the engine, it now has ~750 miles on it.
- The current Megasquirt version WILL control ignition advance as
well, but I need to get the fuel right before going there.
Stock components:
- fuel injectors
- air filter and housing
- temp-II sensor
- oxygen sensor (Cal. Vanagon)
- distributor (so far - will remove the centrifugal and vac advance
mechanisms when I let Megasquirt control the spark)
Custom or modified:
- interface flange/tube between the S-tube and the air filter
housing
- added a GM intake air temp sensor in the air filter housing
- modified a throttle body from a 914 to accept a Bosch
potentiometer type throttle position sensor (TPS) - std Volvo 850 part. I
couldn't use the original TB because the shaft did not extend out the bottom
for the needed TPS.
- put in an MSD ignition system, wires and a zero ohm distributor
rotor (hey Richard! Niehoff WA307 - it has the narrow contact nose, but zero
ohms without modification ~ $7)
- added a new 'double relay' set-up for main power and fuel
- added an add'l fuse panel to handle the MSD, fuel pump,
injectors, megasquirt, and main power (term. 30)
That's the story so far.
