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.

 

that,s obout what i have experienced when i did mien.wow is all i can say

 

Thanks for sharing your results. The 1.2 MPG gain is impressive.

 

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 have also done the mod, though only had it finished it 2 days ago. I agree with all that was said. Highly recommend this mod to anyone with the ***** to break open their IDM

 

Well I do believe I might try this mod if it works well with Jody's tunes.

 

Here is a pdf on removing IDM lid

 

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.

 

So...In short,will the IDM mod. work ok running a DP chip?80e,120,and so on.
Thx ....Schlepprock

 

from what ive read else where, the IDM mod works along with all other programs and mods.
dp-tuner+IDM mod+ICP mod= some real nice power.

 

I posted that I did this 5 weeks ago. But, it was actually about 9 weeks. Time flies when you're having fun. I have run the 140v IDM with all my DP Tunes with no adverse effects. I am actually making as good of mileage in the 120 tune and I did in the 80e.

 

Anyone want to send me a resistor for this mod. I cant find one in this area.I do have access to extra IDM.s if anyone needs one.

 

Can you see the IDM label before you tear into the truck? I want to ensure I have the correct resistor, before I start.

 

Matty169, If you will PM me your address I will send ya a resistor, I think I have a few extra.

Kawajockie, No you cannot see the label without pulling the inner wheel well out.

 

I have a 2003 Excursion, any way of telling by year, or is it just better to look?

Thanks
