Coyote tune problem

[hogauto]

Made the changes Paul recommended and the car runs way better with no hesitation. I would not have had to tune it if I would have hooked it up right. ��. The irmc is not at 4 volts anymore so it must be working now. I’ll let yo know what Lund Racing says on Monday

Paul,
The vacuum diagram in your last post was very helpful to understand the system (even though us Hot Rod guys have to take off the CMCV stuff). Is that something that's available on line, or did you get it from Ford?
Thanks,

I honestly don't remember. That diagram has been kicking around for a few years as some of have been trying to figure it out. Don't remember if I found it or it came from someone else. I personally didn't get it from Ford, I know that. It's for the 2015 Gen 2. The following years were slightly different as I described. The Gen 3 is quite a bit different, so doesn't apply.

Great! I ran my Gen 2 for about 1,000 with the stock tune, and you're right it doesn't run bad. But it really does run a lot better with the custom tune from Lund. Don't regret doing that. It's worth it.
