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. ole blue ----- Original Message ----- From: Dan Martin To: Chuck Blue Sent: Friday, May 12, 2006 11:20 AM Subject: Fwd: Mega squirt 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!

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.

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.

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.

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....

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.
