anyone using late dme/afm in early 944?
 

i am using a late set dme and afm (87) in my early 944 so that i can use the berry chip. everything works great but i have a question:

what happens to the idle valve? mine (early) has two posts and two wires from the dme. the later has three wires. what did you do to make the cold air aidle valve work????

I swapped my early AFM/DME for the late style with no problems, I wasn't aware of the Idle valve being effected. Everywhere I have read about this it was just plug and play. I have an 84.

yes,
the performance is very nice with originally the wilk chip and now with the berry 944max.

my idle when the car is cold sucks.i am in new york and this happens year round. the cold idle valve in the later has three posts on ours, it has two so it may not be working. p

please share your experience?

did you have a smooth cold idle with the early dme?
I did this swap to my 83 in NY and the idle and drive-ability improved, the decell shudder was eliminated with the late dme

i don't remember the before part. i have a feeling that it is not the air valve on mine and could be something else. i replaced most of the vacuum lines, etc.
thanks

Its is a nice little upgrade. I hated when I would pull up to a red light and have a civic next to me, and have my car sound liek it might die, then I would hear his high pitched can, and I would just laugh. But, yes, you can put a late AFM and DME (must be replaced as a pair) and the early car can now be chipped.

Keep in mind that your altitude sensor no longer works when you do this, so you're going to run super rich at higher elevations (and 944's normally run too rich as it is at 5000+ ft). The early cars have the altitude sensor on DME pin 28, where that's just a ground on the late cars, and their altitude sensor is on pin 30 instead. So...

Late DME + early harness = inoperative altitude sensor (way too rich in Denver and similar elevations)
Early DME + late harness = always running in high-altitude mode (too lean)
