Varioram update... No signal from DME

Mark, see this post
DME

As Ingo has stated, just turning the ignition to on will cycle the valves and tuning pipe extensions.

When idle is stabilized they uncycle to their basic running positions. They do not change position again untill 5160 and 5920rpm respectively.

I spoke w/ Steve at length this evening about this topic. He says that the while all the OBDI DME boxes are the same(all '95 993 and all euro 993 '96 on), the chips are programmed for v-ram or not, Cyntex redoes all of the parameters as necessary, yours will probably have the stock cycling points for the solenoids and pipes, mine were moved a few hundred RPM). He said that he does not see the solenoids cycle at first power, but they do cycle where the programmer tells them to, this is only visible on a dyno.
