Custom tunes at Altitude

My reasons for recommending 40HP Towing are as follows:

1. No excessive over-fueling. Towing power will increase but will not dump unnecessary fuel into the engine.

2. No excessive over-fueling. Less fuel will require less air.


3. Mileage will increase over current 80 HP tune due to the reasons above.

Thanks, yes I am permanate at 8000 feet elevation. We will see what Bill says once he gets back to me, as I would need to get the 40hp from him as well.

Emailed Bill when I did this original post - have not heard anything from PHP.... how do I get action on this?

I have a 80 tow / 80 daily / 100hp --- I would like to change the 100hp to an altitude friendly tune so I don't belch smoke.

Currently I am running stock tune while I am at altitude. I can only run 80 daily or tow below 5000ft.

Thanks

I will tell Bill about it tomorrow. For once, he is actually enjoying his weekend so Monday he will find out about it.

It's as easy as putting the new program on the server and you downloading it.

Thanks! Of course he should have a weekend!! I know how busy they are. Its a good and bad problem! Took over a month to get the first modification to my 80 tunes, hoping it wont be too much work/trouble for Bill to whip up a high altitude one to replace the 100hp.

Just have him reply to my email... and I am not trying to use you as a mediary.

Subscribed. I live in a valley floor at 5,000 feet and drive to 6 and 7 thousand feet almost every day. I was looking at the 100 tune for daily driving in a 6-speed but may have to go to a lower tune??? Maybe at 5,000 it's not an issue from what I'm reading.

Thanks for the observations!

The amount of fuel required for an honest 100 HP at high elevation is going to be too much to be smoke free.

[Firehunter]

But when I want an honest 100hp I don't mind the smoke. If I am cruising 65 mph on the 100hp setting there shouldn't be any smoke. The impression I got from Travis's post is he is getting smoke while cruising empty, not accelerating or towing?

Ford kicks over to the High altitude maps at 4500 ft so generally you will see some smoke changes in the 4000 to 5000 ft range.

Kind of but not absolute, the tipping point will be about 5500 so figure out whats happening with the tables.

where in Colorado are you located, I would be happy to take a look at your truck and with Cody and Bill's assistance maybe we can get your tunes tweaked. Bill is coming out for truckfest at Bandimere speedway in August... you may wanna go for some live tuning... I have changed the high altutude maps on Bill's tunes for the CO altitude, however I really need to get setup for live tuning with my Minotaur so I can tweak these settings on the fly
