IDM Mod Impressions
I followed Cookie88's directions https://www.ford-trucks.com/forums/7...-pictures.html
& modified my own IDM.
1. Throttle response improved noticeably, it was already good with the 80e tune, but got even better after the mod.
2. Overall it feels like its making more power but thats just a seat of the pants meter.
3. After 4 tanks full of fuel, my mpg (mixed driving avg, hand calculated) improved from 15.6 too 16.8.
All in all, worth the $6 I spent for the resistors & the 3hrs I took to do the mod.

I need to look into this mod some more, sounds pretty easy. Looking through the threads it looks like the hardest parts are getting to the IDM and removing the lid (and then perhaps sealing it good). The "gel" on the board is a conformal coating to seal against water and the soldering will remove that protection. Years past I have fixed these by spraying hair spray in it's place where work was performed.
I found that ITW Chemtronics makes a conformal coating but haven't found who sells it, but can't imagine doing much with it afterward. Maybe I can convince my employer to buy some since we have so much trouble with water and electronics. I currently purchase various displays for the plant with the conformal coating due to our moisture levels.

I dabbed a little clear RTV, with a Q tip, on the resistor and connections, when I did mine 5 weeks ago. Not one problem, so far. My overall observations of this mod were pretty much the same. Several cuts with razor knife and the lid came off pretty easy without bending. There are some pics in my gallery and what I used to seal the cover.
