Dynamic Map Sensing Throttle Feedback

What part number specifically did you use? Did it already have the spring in it, or did you buy that separately? I am seriously considering implementing this in my truck.

There is no spring... ? The cylinder dimensions will depend on the accelerator pedal dimensions as well as the distance from the cylinder attachment to the fulcrum point on the pedal. I would buy a stainless cylinder, and the vacuum reservoir isn't necessary as long as the seals don't leak in the cylinder.

It shouldn't be difficult to assemble a lean/stoich/rich indicator for your typical narrowband O2, and there are a number of them on the market as well, IMO far more useful than a vacuum gauge.

Ok, gotcha. Thanks
