It's actually more common for reading to be blocked than writing. For example, if the truck has an Efilive custom operating system, you won't be able to read it, but you can write a tune. If it is a...

There's a good chance the radio is interfering with communication. I've seen even stock radios make problems, but usually aftermarket units are worse for that.

In the underhood fuse block, pull...

HP does not have what you're looking for.

Also, this is posted in the Powerstroke category.

For what it's worth, this is what BD diesel lists for their 53% overs. Not that it's an exact match to your injectors, but you can do some comparing at least.

I have no first-hand experience with this exact scenario, but I completely believe you. HPT seems to be on a mission of late to off as many of their customers as possible.

Check your account. It's probably disabled. There are a lot of us now they've done it to. The only "fix" is to send it to Hptuners, and they will supposedly fix it.

I realize I'm a little guy who doesn't matter to your company, but this is a big deal to me, and I'm really frustrated.

I haven't gotten any email responses since the one about the shipping label.

Ok, I'm perfectly willing to email.

Why was my other thread closed???

There's no reason for me to send in my interface. The hardware is perfectly fine. When I received it, I plugged it into my laptop and loaded a tune, and the...

I have a new MPVI3 that displayed disabled as soon as I added it to my account. I need this fixed now. My support number is 418218.

Post your file. I may be able to help.

You should be able to. If you're able to communicate with the ECM, the TCM should be able to talk as well. These trucks can be a bit tricky to communicate with, but there's usually a way to get...

Yes, just be sure not to copy ALL differences. There are things like fuel tank size, axle ratio, etc that you'll want to leave alone.

Sounds like a tune problem.

Yes, but copy the tables. Don't flash it directly. I can do the copying for you if you're not comfortable with that. Just post your stock read.

I ran that tune in my truck as a tow tune for...

There's nothing locked about that file. If Magic Motorsport was trying to load it as a binary, that would explain why it didn't work.

Give this a try.

If you post the file, I'll try to convert it to HPT. I can't guarentee it will work, but it might.

Post your file. I may be able to help.

No, on decel it's fine.

Yes, that gives you rumble at idle. Change it to stock if you want whistle.

Here's a 50 HP as well. It should be safer for towing.

This should be roughly 70 HP.

Click on my username next to my post. It will give you the option to PM or email.

That 50 file you posted does have issues. Try these files. I woud recommend you start with the 50 HP. That will be best suited for towing, and it's cleaner, so better for fuel ecomony as well. I...
