sooo, i just went and got myself a stock 2.0L plenum with stock throttle body and TPS from EASY.
while i was cleaning the stuff i noticed that the TPS didn't have *any* gunk on it, it fact it looked shiny new. so i pop the plastic cover and low & behold it looks brand spanking new! no wear on the sliders at all ... so i'm thinking, can i use the stock 2.0L TPS with my MegaSquirt brain or do i need to go to a aftermarket TPS ??? also, when i took the plastic cover off 2 little rubber spacers (triangle shaped) fell out. i can only see 4 spaces where they might go, but which ones is it? top or bottom?

andy there is someone who did the MS on a type 4, well they used a suby tps, i dont know why but i think it has to do with ohms of the stock tps. if you need i can go get a reading from the one in my car ( suby 914 )

You can pretty much use anything under the sun with megasquirt. Guys are using AC delco sensors, bosche sensors, etc...In my research for my MS project, I ran across all kinds of different stuff.
Check this site out: http://www.dune-buggy.com/turbo/index.htm and this one: http://www.megasquirt.info/ This one too: http://bellsouthpwp2.net/s/_/s_moseley/meg...gasquirt/msgui/ Here is my MS thread: http://www.914world.com/bbs2/index.php?act=...f=2&t=23859&hl= Picture is of my setup as it is now. How far along are you? Corby Attached image(s)

Big no on the stock TPS.
The stocker is basically like a switch, where a modern TPS is more of a rheostat. |

a new tps uses a variable resistor right? the stock tps is just like a multipoint switch. the new one would be way more accurate. i'm sure someone has something alot more smarter than that to say. (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif)

i'd buy that stocker from you. i was gonna buy a new one shortly...it reads coninuity and infinity in ohms, no progressive sweep like a std tps would

Thanks for the digs! (IMG:http://www.914world.com/bbs2/html/emoticons/beer.gif) Here are some pix of the progress. On another note, I have a EET from ITT Tech, and have been working in the electronics fields for 10 yrs now. I would be willing to build these kits for a small fee if anyone is interested. I can even hook it up to my laptop and pre- tune it for stock or? Attached image(s)

You can get one from SDS but they're spendy at $75. If I remember right the 2.0 TB turns opposite (I think CCW) from most TB's You can see the "D" shaft on my install thread here...BTW that's a hacked up stock TPS that the new one is mounted on. |
