Looks good. Where did you get the knobs and housing? Total cost in the end?

How well does it work and do you have a schematic?

havnt tried it yet, and have schematic on paper only (and will not give out until knows it works). Only took 1 hour to assemble (first one always takes longer) after getting supplies.
will install tomorrow.
and is way to hard to find a schematic online. :(
as u can see it has an ON/OFF switch and CITY/HIGHWAY mode.
and ordered gold plated / aloy knobs - $2.00 each! :eek:

So i was doing more reading and testing of mine(without mod) on map sensors, and found that the map read just a smidge over 2V at idle. And on full acceleration was near 4.6V.
didn't install yet -just testing regular drive volts along with acceleration.
does anybody know the voltage when the computer goes to open loop??

Would any one know why that schematic show a 50k resistor on a single pot. and a 33k on a double pot.

OK tested the map enh, and works not to bad.
so far for idle i set the highway near the factory setting.
but when running down the road, it runs good even leaner than idle will allow.
when cruising in town (steady speed) i get 38MPG, and on highway i get 54 mpg. - and dont thing it is running too lean cause my power is near stock power, even goes u hills ok dialed down.
and tests are on a 89 cad deville with 4.5L - that usually gets 25mpg or soo intown and almost 35 on highway.
need to hook up a temp gauge.
and i also moved my vacuum tube to the pvc valve and added a line after the air filter.
this is a must for people that havent yet line after the air filter
made a big diff just driving around town.
