Why did you leave lund?

I'd just run 93 on a road trip. For the fuel mileage alone.

depends…there are large swaths of the country that don’t have 93!

i just keep a couple bottles of Boostane in the go-bag

From the little bit I've read on Flex tuning it wasn't real time flex. It was based on reading the O2 sensor to determine E85 content which introduces more margin for error.

Real time flex has a sensor in your fuel rail that can can be used to adjust for E content in real time. I know PCMTEC supports this.

I'm sure someone with a much deeper knowledge base will be along shortly. After all I'm just an average knuckle dragging ape with a basic understanding!

Edit: I found the video for the PCMTEC solution.

Its inferred very similar to the logic ford uses in their flex vehicles that come with warranties. I get using a sensor would be more accurate and adjust quicker but it still works.

Im not watching a douchy Alex video sorry but he was saying that same crap back when every other tuner there said it was fine to run the flex tune full time as long as you let it adjust after each fill up with different fuel. Again, I ran mine on and off for 3 years with no issue. I preferred the e85 and e54 tunes I had simply because the down low timing was night and day.

For Gen3, I believe Lund didn't have access and/or didn't know how to make flex work right in the Mustangs due to missing parameters in hpt. The video above is a load of baloney. He seems to a) have lots of air leaks and b) doesn't understand how the OEM diagnostics and learning routine really works. Ford was pretty smart about it and air leaks can't cause ethanol learning problems in all but the most remote obscure situations.

This is interesting because my 19 had a lund flex tune that worked well. It was back when they used sct devices though. Could thst be the difference?

I have a flex tune aswell , not by Lund though . I only posted the video because you said you weren’t really sure why they stopped offering it .

I meant not sure of a good reason!

I doubt it. The problem is that they would prematurely lock in to the new fuel before the fuel system was fully purged. This caused a couple of things to happen, one being improperly learned ethanol resulting in fuel trims being off, what he probably thought was due to an air leak. The other issue is it would take a couple of tanks for it to finally learn the right number, which I’ve heard people talk about, so it tracks.

Thanks for all the responses guys I appreciate the insight, from what im getting most people switched because of lund not supporting all company's and demanding you buy specific brands (which i can see both sides of the argument) and customer service.

Idk. I think Lund had earned a good name for offering reliable tunes that did the job snd minimized the chance of messing up your motor.

I hypothesize that where the tightening up of what they offer and what they dobt comes from. Yes they used to do more, but it likely increased the uncomfortable variables. And if there’s a part they’ve struggled with ensuring responds reliably? They might elect to not invest there.

The great thing is that there are options. You can go with Lund, get your banger tune with peace of mind, or if you have a combo that makrs them unsure they can give you the full Lund peace of mind package, then go somewhere that will do it. Win-win.

It’s nice living in America.

I switched from Lund (nearly 13 years ago) because I bought HP Tuners and started to learn how these things worked. Back then I was beyond ignorant, but I was learning.

Ever since then, on this platform (modern Ford/Coyote) I will never buy a tune from one of the "mainstream" tuners again. I have much more confidence in what I am doing.

Regarding the flex fuel discussion, I have made multiple posts on here discussing the pros and cons of the OEM flex logic and PCMTEC's sensor-based logic.

The bottom line is both work reliably and seamlessly...if they are calibrated correctly.

My position on the mainstream tuners remains the same as it has been for years now: pick the one that gives you the drivablity and customer service you want. They're all turning the same screws inside the calibration and they all end up within a performance margin of error of one another for a given setup.

The only modification to this recommendation I have lately is to make sure you can flash your car with a laptop. This likely means you will need an HPT device, either an RTD or MPVI of some sort (or possibly PCMTEC Flash and Log access from your tuner) but that means you will be able to data log your car and view/share the data logs as needed. When your car decides to have an issue, and it will, you will be able to log it with a laptop and share that log with the community to get assistance. The flip side is you flash and log with your phone, or some other device, and have zero access to your data logs. Understand what TDN, and other flashing devices, do and do not allow at your own risk.

Every day, there is a new post on multiple facebook groups, about someone having issues with Lund, changing to a new tuner and the issue being resolved almost immediately. It is crazy. With all the info out there now, not sure why anyone would choose them anymore, when there are several, much better options out there for the average joe.

They wouldn't fix my stalling issue. They wouldn't even look at a datalog unless I threw them $50 dollars. So I did. They didn't fix shit. Went with a different tune, issue went away.

Spent money on Lund and their device, but when it came time to remote dyno tune at my local shop, they couldn’t get it done. I had to make a split decision on the dyno to purchase another device and use a different tuner that made himself available in that moment to get me taken care of.

Spent a couple grand that day, but 8 years later I’m on the same tune going strong. No regrets.

Zero complaints with my Lund flex tune (nGauge) and mild engine mods after several years. The car flat out rips on the corn juice.
