I posted the patch for the 96420008 almost a year ago. Its in the first post.
Just checked, and I have written a patch for the Evo 7 98640014 ROM. RMutt paid me to do it. I'll try to take a look to see how easily I can port it to your ROM series.

MrFred, you said there is an address that logs the MAP sensor input in 2 byte rather than 1 byte before when we were trying to get the zeitronix 3.5bar map sensor working. I wanna start gathering data for that but I would need to be able to log the raw 2 byte bits to start figuring it out. Any way I can find out what address that would be for my 94170015 rom?

from what i have seen the jdm 3bar will only read up to 30ish psi. is there any hope for us guys running 32-35psi and be able to log boost? maybe figure out how to get the aem 5bar sensor to work? sorry if this has been talked about already....thanks

I can make it work, but there are so many things on my plate right now. Keep asking, and I'll get to it eventually.
Is there any programming that's required to make them work?

A 5 bar sensor will require a special patch to give good resolution. I have been promising something similar to Jack_of_Trades for many months, but just haven't gotten around to it.

Working on my heat pump system tonight. Outside temp is ~10F for the first time in maybe two years or more. The aux heat is blowing the breaker, and in looking at the air handler specs, it looks like the HVAC installer used an undersized breaker. Ah the world of professionals. Some really are professionals. Some are just masquerading.

Boils down to being -16 outside, heater will only go up to 69* and quit. My son is 8 months old and thus cannot control body temperature. I and my wife had to wrap him in blankets and his Eskimo suit to keep him warm through the night.
Come to find out, the filter was clogged preventing air from keeping the sensor cool and not tripping it.
The wife sent me to the garage to sleep in the Evo for an hour.-E
