Phoenix Switch-On-The-Fly Chip (DISCOUNTINUED) (Disabled)
Power Hungry no longer sells the Phoenix/TS chip, but if you need custom tuning we can recommend a few really good tuners that will be able to still provide tuning and support for your chip.

If you have any other questions or comments about the Phoenix/TS chip, please post it here.

Default what mods work with a chip

I was wondering what mods work with a chip and what would work against it. Specifically I was thinking about the IDM mod for the powerstoke.

As you've probably read, the IDM mod has the ability to advance the effective SOI (start of injection) from what a "typical" IDM will do. This is because the injector actually opens roughly 120mS (give or take) sooner than a stock IDM because of the increased electromagnetic field working on the injector armature.

I would say that MOST times, it's not going to be an issue with any tuning...however, if your combustion pressures are already on the ragged edge due to SOI being too soon, then it MAY become an issue.

It's not a bad mod for a mild truck with standard tuning.

A "10K" type fueling module modification such as an Edge Juice or Banks Six Gun (or any of the thousands of assorted look-alikes) will work against a custom tune on a chip because usually the tuner will have already desired a higher ICP in certain applications....and the ICP fooler will "ask" for more. This will definitely tax the high pressure oil system and usually cause higher EGTs with no power increase. The high pressure oil pump can't keep up. Then 7 seconds later once the P1211 code sets, you'll be running on the default IPR table and losing what was programmed anyway.

I'll think of more, but I have to get back to work.

First let me introduce myself. My name is Chris. I have a '99.5 F250 Auto 2WD.

Don't want to bring up such an old thread, but I have a question about the IDM Mod and tuning. I will be getting a modded IDM and soon after will be getting my chip. Just how well do they work together. Is it something that will hinder or enhance my tuning? Want to make sure before I get the modded IDM.

Here are the tunes I'm thinking about if anyone thinks that it will impact different tunes in different ways. Could also use some suggestions on tunes.

1. Stock
2. 65HP DD
3. 80HP or 100HP Performance (Really not sure between the 2, could use suggestions)
4. 80HP Tow (Not sure of this either, I only tow between 2000-3000lbs. Not sure if I need this or if I can just tow in the DD tune.)
5. High Idle 1100 RPM
6. No Start

Thanks for the help.

I think with tuning now days the timing curves are very conservative, and adding a modded IDM should not cause any negative effects.
