Another problem I'm now experiencing is both of the Aeroforce gauges have gone to shit. One of them will only turn on if the car is in ignition -> accessory but will black out once the engine is started and it also now has a fantastic dead pixel line that goes vertical... and the other one is just dead and only blinks the red shift light every 30 seconds.
I had the same issue with one of my dual AF gauges with the constant cycling of the start up screen followed by the shift light flash. I contact AF by email and they had me send it in. Within a week it showed up in the mail and it seemed to work fine. But I was a bit frustrated as it came with zero paperwork, so I contacted them again (by email of course since they have no phone) to find out what was done. And I was kind of surprised with their response as they simply reflashed the firmware.
Of my 2 gauges, this one still seems to be quirky as the last time I drove the car it started the same routine of recycling the start up routine. But a quick unplugging of the OBD cable resolved it.
What type of analog boost set-up are you using? Asking because I am using an analog MAP sensor to read mine that is hooked up directly to the E-force, and the output from the MAP is all that feeds the analog AF input. I did need to find a 5v feed under the hood for the MAP, but nothing else was required on the AF gauge. I will dig up a thread I did for the install to confirm.
