cylinder head temp sensor, what the brain thinks Options

[worn]

Well, I have been tweaking the MPS. I still am having low torque below 2,000 rpm, making smooth transitions to speed a bit more dramatic than I would like. I think that the cam may be playing a role here that I may never tune out completely. Now over 2,000 is another story (IMG:style_emoticons/default/laugh.gif) (IMG:style_emoticons/default/w00t.gif)

The point of this post is that if you are fooling around and the cylinder head temperature lead (I think it is Temp I) comes undone, the brain sees infinite resistance. It therefore, on a warm summer evening, thinks the motor is frozen cold and dumps in fuel. It won't start. You have spark, you have fuel, but the thing is flooded to the gills. Nooo, its EFI! Yep, flooded. (IMG:style_emoticons/default/hissyfit.gif)

So I started thinking that a spare might be in order since no start can mean travel by foot - or used to before cell phones. An alternative would be alligator clips to simply ground the lead. That way the brain would think the engine was hot and you could limp home. My list of spares on a trip away from home is growing.

Ask SLITS nicely if he has the 411 VW mps unit he could sell you.
It does not have the lower end diaphragm, so you can use camshafts that are a bit more aggresive.

Btdt, tuned two large motors with it, works fine and a ton simpler to setup, just one adjustment.

You will need an O2 sensor and some AFM gauge to read it..

Drive, adjust, drive adjust...
Take about 30 minute of tuning in all types of driving types to get it as close to right as you will ever get it...

Djet is really n a finely tuned system, it batch fires when it wants, not when the motor is really in need of fuel, so don't attempt to shoot for perfect, shoot for perfectly drivable.
