Rev built MS2 baro correction not working
 

I purchased this ECU and it had a single MAP sensor installed. I replaced the sensor with the dual mapdaddy sensor and ran the wire to JS5 which as far as was the only hardware modification I was required to make.

My understanding that the resistor that is mounted on the mapdaddy on some installs was not to be installed for the MS2+.

Right now I am running it with "initial MAP reading" which where I am located at 5600ft varies between 82-83 kPa and the car runs fine.

The problem is when I switch Baro Correction to "two independent sensors", it constantly reads outside air pressure at 100. I have tried changing upper limit, lower limit and default baro and there has been no changes whatsoever to what MS sees.

I know I fuxored some of the insulation of the surrounding wires, but I made sure to hit them with a dab of hot glue to make sure they would not short on anything, and they are completely free-floating.

In for results as they affect me as well.

That's not going to work as both JS4 and JS5 are used internally. The expansion board inside the ECU (version 4.6+) has provision to solder a baro sensor on it.

The catch is that it must be a 1-bar sensor - the MPXH6115A6U.

Alright, I just got one of those today.. will be contacting you shortly
