To mark an event, you can trigger the digital input with a pushbutton or handcontroller. So when you are driving, you notice something you want to look at later, you trigger the dig input then its easy to find later on.Tazzi wrote: For the digital, how would you implement something to "mark" an event? If that makes sense.
Its easy enough to chuck a couple digital inputs there which can 'mark' an event, but what will be used to mark the event?.
From what I understand, the WB input can go straight into the analogue ports? Do some use a RS232 connector?... now thats an interesting one.. size of the rs232 plugs is annoying.
I like the idea of being able to expand the device later on if need be. So Iv purposely left a set of SPI pins available for expansion ideas.. or even connecting up some sort of expansion module.
Hmmm.. what if... maybe.. the RS232 is a plug-n-play expansion module?
Next, what is fed form the dyno.. and what connection does it use? Id assume a simple serial connection?
As for the additional CAN connection, theres already two CAN chips on board
But.. actually.. using the CAN network as a way to expand and add modules is not a bad idea! A third CAN module (If I can fit it in!) could link directly to expansion pins along with power and ground. Then a 4way connectory attaches and the new module is instantly supported. Hmmmm... the possibilities...
Most widebands output a RS232 stream. No need to worry about offsets, grounding, transfer function etc. And you can also get the heater status. Techedge, Innovate, PLX, etc. all have it. With the Innovate I believe you can chain the individual widebands on the serial stream and log quite a few at once. You don't actually need a DB9 connector, just the TX/RX pins.
Mainline Dynos have a serial stream that has Power, Torque and other parameters logged by the dyno computer. EFILive has this defined so you can log the ECM, TCM, DYNO into one log. Great for working with MBT timing etc. when you don't have RT capabilities. Other dynos may have the same thing.
