I've hillbilly tuned my passat TDI with decent results, both on diesel and
vegetable oil. I think it's called the "beer can mod", because it costs the
same as a can of beer. Learned about it on the TDIclub. It's basically a
potentiometer (1k ohm maybe?)wired in parellel with 2 wires on the injection
pump that monitor fueling quantity. With a turn of a dial, I go from stock
fueling to a bit of smoke at max setting and full throttle. Works great for
passing, or for blasting some obnoxious tailgaters with a little smoke.
I hooked it up last year when I was ice racing on Lake Champlain, and it helped.
Obviously, you'll need to find info on TDI club if you want to try it. One thing
I notice is it needs to be turned down to halfway or less when I shut the car
down, or else I get a blinking glow plug light for the next half dozen
startups. It eventually resets this light however.
So, no where near the sophistication of the tuning boxes or chips, but it does
deliver more fuel when asked!
