kris Posted December 19, 2006 Report Posted December 19, 2006 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 Quote
ashesman Posted December 20, 2006 Report Posted December 20, 2006 Good idea... I'll mention about adding analog inputs and temp inputs as an option. What types of extra inputs do you need? Also note that it is the amount of I/O tghat differentiates between ECU price levels... Quote
kris Posted December 21, 2006 Author Report Posted December 21, 2006 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.

ashesman Posted December 21, 2006 Report Posted December 21, 2006 Most intake runners with variable length just switch ON/OFF. If you are planning to try and have a continuously variable length runner then you will need a closed loop control algorithm like a PID controller or similar. There are enough conditions for the GP output to have a reasonably clever control of the motor. Best to use IAT if you can. IAT is one of the reasons that the G2/G3 platforms have such a stable and repeatable tune. You request has been put on the "Things people have asked for" list and will no doubt be added one day...

kris Posted December 30, 2006 Author Report Posted December 30, 2006 thanks., good to hearyeh 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 Quote
