What about boost?

Boost should be possible.

Off the top of my head I see a few different ways this could be done. Stand alone MAP sensor connecting to the bluetooth server sensor, tap into factory MAP sensor, or if you are tuned, there might be a way to get that off the CAN bus.

Tuned on Ecutek by Seb at Specialty Z. Any way to get the AF to read off an aftermarket O2 sensor instead of the factory sensors?

It depends on the AFR gauge/controller being used.
For example, AEM's X-Series controllers have a 0-5 volt output that is proportional to AFR and they also have a CAN bus output of AFR.

Tell me what gauge/controller do you have and I will look into it.

Also, I have verified that boost levels can also be read using OBD Service $01 (live data)


Thanks for the excellent questions and keep them comng

I use the AEM 30-0310 X Series controller with a Speedhut gauge. Good to hear about boost readings

Hey Frank, since I'm on a roll here, what about ethanol content? I'm currently using the Zeitronix ECA-2

Yes, the ECA-2 has a 5 volt output that can be used as an input (Ethanol % = 20 * Voltage)

Also, I could get the ethanol content and fuel temp from a typical GM flex-fuel sensor. They have an output of 50 Hz (0% ethanol) to 150Hz, 100% ethanol.
That is easy for a microcontroller to measure and calculate.

With that said, I haven't done this, so I would need to do some testing.
