How do I lockup my converter for dyno testing??? I want to lockup my Fuddle converter when I go to the dyno so I can see if my nitrous is just blowing through the converter. Can anyone tell me how to do this without any tuning software? THANKS

dennis? You have done a search on here and you have to wire up a toggle switch to the tcc solenoid and such. ill see if i can link you to it.

Off the top I would say you want a DPDT switch like:
side 1 - common to TCC solenoid on trans, NC to the
PCM TCC solenoid drive, NO to ground
side 2 - common to TCC PWM on trans, NC to the PCM
TCC PWM drive, NO to IGN +12V source
Then normally-closed (NC) will be normal operation and
the other (normally-open, NO) will be hard-locked with
full TCC duty (100%).
You might substitute a DPDT relay and drive the coil with
a cuter, pushbutton switch etc. and maybe add a LED
indicator just so you don't get hung up; if you are into
relay logic you could make it latching and unlatch with
the brake light etc. too.
