does nistune have outputs?

Just thinking along in my own little world and i was wondering if nistune was capable of supporting on-board outputs..... just like logic high for X seconds under condition x type of afair
personally i would love to see an output for a simple lght to illuminate when major knock is detected (assuming all goes well with the knock detection part of course)
reason being if say you are out on track you dont want your precious laptop being thrown around and a little warning light just to say "oii you twat! you're gonna blow the engine in a minute!!" would be amazing
Just a thought

You dont state which board you have, but Matt is working on getting the check engine light or exhaust temp light to flash when detecting knock.

type 1 board buddy s13 ca18det so no temp or check lights to flash...... thats why i was thinking external logic output that could be used to drive a transistor and bulb/led style arrangement

I've thought about it over the last week and memory mapping any spare CPLD outputs to transistors is the way to go

However at this stage I need to get through a lot of stuff added to my list over the last month as I'm getting behind

It would mean new boards, firmware and more testing on top of the current work load so I'm not implementing anything like this in the short term

would there be no way to adapt current board matt??

not currently. i might have run out of outputs from the CPLD chip on Type 1 board. Type 2 board isnt such an issue since we have lots of pins on there

also you will notice no more physical space on the board itself to fit any more components. ECU spare space has been a major design limitation from the start of the project. We had tons of space on Z31/R31 ECUs with our earlier Rev1/2 boards but Rev3 got shrunk to fit perfectly inside CA18 ECUs which we determined to be one of the major ones used
