yeh you can just use one, progam it in the logic to turn on/off at what rpm you like

thanks., good to hear yeh they are just 2 stage, on/off as you say. had to use the iat input, as well as the di input in the end.  basicly to tell the ecu when the runners are at the top or bottom. its all up and running now anyway, seems to work well

well its something a bit diffrent .. its a 16v 4age, with quad throttles. i have built a variable trumpet setup for it.  just 2 stage, long runners for low rpm and short for high rpm. has a windscreen wiper motor on a cam setup to rase and lower the runners. plan is to mount switches top and bottom of the runners, so the ecu knows the position.  then use rpm switch +  one of the inputs,( one of the switches on the runners to tell the ecu the position of the runners). witch will switch a gp output. but yeh, for now, i'll use the DI for one switch. looks like i'll have to ditch the intake temp sensor for the other. and swtich a resistance onto it the voltage and/or gp temp inputs added to that list would be awsome.

hey, is there any plans to add more options to switch the aux outputs, when setup as a gp ouput?, at the momet theres %ff, rpm, map, iat ... etc. can the analog volt channels be added as well? voltage 0-5v, gp pressure, wideband etc? one extra input would be very helpfull. for what i need to do anyway. thanks kris
