the xdf file isnt different, its crai8 as well

whats the purpose in writing over the file?

yeah its pretty common for ecus to get updated when a vehicle goes in for service

read the comments for each parameter and it will tell you what its for

Michael,
I see now that my '99 pass car bin file says CRAIB and not CRAI8.
The file I was suggesting writing over Is another '99 PCM.
I'm familiar with flash bin file upgrades.
I'm reading each parameter and wondering if some need changed and would some have inconsequential results.
There are some that I'm not sure if they need changed. I've eliminated the CATS and rear o2 sensors so of course I would want to turn those off.
Also I've eliminated the EGR.
I'm curious as to whether the gear ratio or tire size needs to be adjusted. The '97 Mountaineer has 3.73 gears and p235 70 r15s.

thats all up to you as the tuner and how involved you want to get with

but yeah you have to use the crai8 file since you cant edit the craia craib or any of the others.

Fuel lines completed. Ford spring lock to AN fittings and SS braided hose. Upper fittings are opposite of the lower fuel line connections. Lines removed again to install power train wiring harness.
