why wont mopar pcmswork on turboed neons.

any one have a stock r/t pcm layin around?

 

i think because the way that it is tuned

it feeds the car really really weird
and if you can't get the ride octane it runs weird

 

most after maket PCM advace the spake to achive higher cylinder pressures. Too much advace in turbo cars can cause detination

 

yea but there is the other side of things where the companies make computers just for turboed cars

there just isn't one for our cars!

 

Not neccesarily, you can use Megasquirt as the PCM

Some PCM's are tunable, but the neon one isn't. Thats why we have to use a MAP clamp or missing link to keep the PCM from seeing boost.

 

Explian the map clamp and missing link... how it works.... Its greek to me...

 

The MAP clamp cannot see the boost from the turbo, so you need something to keep it from seeing it. Thats where the MAP clamp or Missing Link come in...

a map sensorsees the voltage change from more pressure in the manifold and it only sees vaccum not boost and adjusts the air and fuel to correct the problem....
a map clamp holds the map sensor at its highest voltage but wont let it go any higher...and then hides the boost from the pcm.......basically

 

Is it possible to make a home made map clamp? or use resistors as if you were fooling the IAT and map for more HP only you would fool them to just make it work with Turbo? lol

 

Alot people make their own for about $5-$10.
