More Integrated S4 Boost & A/F Stuff, plus another idea.
I am sure you folks are getting bored with this subject, but I am trying to refine my designs and you lot are a pretty good source of non biased information. Just let me know (not too harshly please) and I will quit posting if it get's tedious.
After running this setup for over 3 weeks in the Audi now. I am finding the Air Fuel Meter portion of the dash is of limited use, and spends most of the time switched off. I am seriously considering, removing the A/F part and replacing it with a Fuel Injector Duty Cycle meter or for those with Water Injection, a Water Injection Meter that shows how open the fuel injectors are or Water solenoid is. (in fact the dash is out again as of this morning, man I do that a lot)
Do you think it is overkill, and the A/F is more useful or.. any other ideas for locations. I think it would be better to have a stand alone A/F Meter that can be removed when tests are complete.
Instead of posting the picture every time, I will post a link to the dash. I cannot find anywhere else to put a Duty Cycle Meter.
Thanks

I have a design for that already (A/F) but where would you put it?
In practice, from experience I personally found especially for air fuel because of it's inherent erratic nature, LEDs are by far easier than reading and deciphering the numbers. You just look for Number 8 LED at full throttle.

OK I just researched Type K Thermocouples (The EGT Sensor)
I can design very easily, an LED or DIGITAL readout version. The digital readout would be about 2.7" x 1.5" or 10 or 20 LEDs. Quite a simple thing. Cost would be, "guessing now" $80 for either option. LEDS take less space overall are are easier to install in my opinion, but the white lettering takes a steady hand to install.
