I wrote a custom patch for Evo VIIs. I thought I posted it. Do you want it?

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.

Not yet. I just finished up my boost solenoid analysis. That blew about 8 hours of my free time over the last two days. Need a rest now, but I'll get to it.

Do you or Jack know what the values in the EGR offsets mean. I want to try getting a zeitronix 5 bar sensor working on the mdp port. Any tips or advice would be appreciated

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.

What are the challenges involved? I'm new to this corner of the ecu world, if its just figuring out the right settings i can probably figure that out on my own if i just knew what the settings meant, thus my origional question.

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.

I was just giving you grief. Your situation sucks... Been there, done that. Matter of fact, when there's a child involved, I start getting really red mist pissed.

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.
