2023 5.0 tune

[csj72]

I'm loving my 5 Star Tuning performance tune for my 23' 5.0. It rocks with E85 in the tank! Consider giving them a shot.

Is your tune octane specific or just adaptive?

it's a 93-e85 tune, and likely has base timing set assuming 93 octane. I could ask for an adaptive tune but this works for me.

OZ Omega tune. 1 tune for any fuel. Max timing is seen around e40 depending on the quality of the ethanol.

Livernois creates and manages the Ford Performance tunes, they have a deep history with SVT and Ford Performance/ Racing.

That is why they usually are the first ones to "crack the code."

I was running Livernois tuning on my 5.0 for a while. As far as the most effective one to buy depends on your feeling about the tuners. Livernois and OZ seem to be favorites, but there are others. I went with Livernois primarily because they were one of the first, if not the first to break the encryption that doesn't require sending out your ECU. That and they have a pretty decent reputation from my research. That's not to say OZ or the others aren't just as good, but at the time Livernois was it for me...

The Livernois process to install a tune is pretty simple. It's basically a two step process where you connect the programmer to the OBD2 connector in the vehicle. This step puts the ECU in a state to accept the tuning. Next, open the hood, disconnect the three large connectors from the ECU, connect the programmer to the ECU and battery and upload the tune. My only concern with the process you don't disconnect the battery when you remove the three large connectors from the ECU. They do tell you to remove the inner most connector first, then the middle, then the outer most connector. Still, my gut tells me to remove power before messing with the computer

I hope this helps.....

They must have changed something after 21, because I haven't had to hook up to the OBDII a single time after the initial process of downloading the stock tune to send to them. Any tune changing is all under the hood.

edit: well apparently I was supposed to be doing the OBD2 thing the whole time, but can also confirm that it doesn't appear to be necessary. I've swapped tunes a dozen times without doing it and have had no issues. I think it was something I just forgot was part of the process after I had gone a while without switching anything.

Edit2; ok all it does if i connect it to the OBDII first is tell me to plug it into the ECM. I don't think anything else is going on, so I'm back to thinking it's not necessary, especially considering it has worked perfectly up until now.
