yea, and on top of that, nobody knows how to accurately adjust the fuel mixture on a m103... so far all ive been able to find is "rich" or "normal"...

im curious as to where i can get one of these 470 ohm fuel enrichment thingies

I would make my own if I were you, requires a 470 ohm resistor and about 5 minutes...

any info on how this can be done?

Badinfo,
I found the info you wanted,
Snip the wire to the injection system engine temp sensor B11/2 (rear of cylinder head on left side) - it is a green wire with a red stripe. Then splice in a 470-ohm resistor in series. This has the effect of telling the injection computer to enrich the mixture just a bit at idle. Putting a switch in parallel with the resistor will give the adjustabillity you described previously. I leave mine resisted constant. It dosn't seem to effect emmission controls or the cat.
also the engine controls are driver adaptive so, constantly switching it on and off may fool the controler into operating rong.
Either way have fun experimenting!

Thank Adam for that... he is the man you know...

Would it be ok to just cut the wire or do you have to splice in the 470 ohm resistor? I don't think I have one of those resistors lying around, so I'm curious as to how important it is.

anybody anybody? I honestly have no idea, I would imagine that infinite resistance would make the ECU think something is horribly wrong and go into some type of uber-safe teutonic we will get you home in one piece so you can spend a billion bucks to get this car fixed mode... but im not sure if our lowly 300s have such a feature...
