Spoke with Cody at Stanghi yesterday.I’m sorry if I didn’t post all links in my original post. I listed the company name and enough info so that a person could find it if they really wanted to. I didn’t want to make it seem like I was pushing “my tuner” on anybody. It seems people are polarized with their tuners—almost like political parties. They each have their followers and fiefdoms. I just wanted to get the info out there. Every time fuel tank calibration discussions had came up in the past, someone without a clue to the problem always poisoned-pilled the topic.
I am not the expert at this, but I think I’m the first 2025 that has had it done. I research this for months and reported what I knew. I gave the info on EzLynk, because they were the first company that I think made it possible to do, and did it for S&B. I don’t know for sure, go look in their website, and see what their core mission is.
They are a PID development company—they sell specific modeled data to other companies or tuners to modify all the factory hidden or locked programs.
What they do for S&B is, I think is proprietary software (S&B paid for it), if you bought a tank from S&B, the use of the software was free, but the actual program device is proprietary to EzLynk. It’s free if you purchased a S&B tank, you pay a fee if it was another brand and have to return the device to EzLynk. I do not know if the program is actually stored on their device, or it has to be retrieved from an online account—but, from how I thought I understood it, it was in the device. Everything above is just conjecture as I have a lot of assumptions.
In my case, Cody somehow figured it out, he may have used a 3rd party development company, or he may have done it himself, I don’t know —and I didn’t ask, because even if it was, now—I believe it is proprietary.
I use HP tuners. I have an account on HP Tuner’s Tune Delivery Network (TDN). When a tune, or a program change like this is made for my truck, the tuner puts it in my account linked to that vehicle only (seems kind of like a big file for me on the cloud). When I want to install the tune, I link my cellphone to the HP Tuner’s MPIV4 device (what everybody calls the tuner), with it plugged into my diagnostic port on the truck, and download the file to my truck. The program/tune is never stored in the device—the device it is only the communications “modem” to get the tune/program downloaded from the TDN, and off my phone into my truck’s ECM/PCM.
Having the MPIV4 device come pre-loaded as suggested, I already know doesn’t work that way. Your vehicle, your account, and the device all have to validate a handshake with each other to work. And, like I mentioned earlier, the tuning device, is just an empty vessel that bridges the devices—it doesn’t work by itself.
Can you borrow someone else’s tuner? I am pretty sure it can be done because it almost happened to me. I had an installer willing to help me tune my truck. I went to the tuner to buy the tune and the device. They were out of stock. It was such a tight fuse with little time to plan. The tuner came up with a plan with a way of re-registering, putting my tune in his account—or something weird like that which neither of us liked.
I under stand people not wanting to fork over $350 for an HP tuning device. For them, I would say just wait. Like always is the case, once something gets cracked, everybody does it. In a couple of months from now everybody will know how to do it and different options will probably (maybe even EzLynk) may become available.
But, if you are like me, those gauges reading incorrectly drove me nuts—I paid the money—and don’t tell Cody, I would have paid a lot more. For now, I think this is the only way.
‘Turns out he is the is the one doing all the tuning on the Juicy / Maxlider Godzilla swaps as well others doing Coyote swaps.
‘I ‘Learned more yesterday in a 15 min conversation with him , then I had from the other guys involved in my RR Godzilla swap project.
Cody really knows his stuff. Very impressive dude.
Thanks again for sharing your experience and info about Cody.
Very thankful, getting to speak with him yesterday.
