Flex fuel Tuning

[GL95]

there is a lot of development involved.

You’re forgetting that they have to design a custom bracket for the sensor holder, hoses and wiring harness. The hoses have to change depending on if the car is SC or not.
the ECA has to sit somewhere, you’re not just wiring the sensor directly to the ECU. The ECA needs switched fused power which has to come from either the engine bay or the passenger footwell, while the sensor has to go on the drivers side. That wiring is a pain.

It’s not a trivial thing to come up with, it has to be perfect because it’s a fuel component.

The need a fabricator willing to make the brackets, a company willing to make wiring harnesses, a company to supply the hoses. Are they gonna use a radium ECA holder and apply markup to cover the cost? They have to kit all these parts, and worse they have to verify that it works.

Then, they need to provide tech support for the endless swarm of people who installed it wrong.

I do not blame Lund at all for not offering it. If someone else starts selling it I bet they’ll support it though.

Why do you think Lund is going to sell these parts? I don't understand the thought process, literally none of what you needs to be done. They already offer user flex, the only difference for Lund is instead of selecting user flex they select canbus flex in the tune, the tables are all exactly the same

All Lund has to do is flip the switch so to speak and send a parts list and install directions. I believe there is instructions on PCM's web site.

Besides it will be cool to see people post links to the Lund dummy on YT calling people more names.

They don't even have to do that, PCMTec already provides a parts list

because no matter who sells the parts they will be on the hook for customer support

• option 1: Lund sells all the parts in a kit that works every time, it costs more money than anyone wants to spend. You're looking at something in the neighborhood of $1500 to get flex working when you consider the price of the tune too.
• option 2: Lund attempts to support user installs, fielding hundreds of emails about "my flex tune doesn't work" and has zero clue how anyone installed it. They send responses saying its a hardware issue which generates countless threads exactly like the ones we've already seen here about how "Lund isn't helping me they keep saying its a hardware issue but it isn't".

If the demand is there the kit will be offered, but i see threads and discussion here all the time where people still can't understand the need for inferred flex let alone sensor based flex. I can't tell you how many times I've seen flex dismissed entirely because "just run e85 all the time".



All of what i said needs to be done, its not so simple.

Then why don't they sell parts for anything else? The kits are already for sale just like any other part they tune for without doing what you are saying. Sensor based flex fuel is not anymore complicated than user based flex

Who's selling a CAN bus flex fuel kit for the S550?

Juggernaut has one for sale.

Still not sure what difference it makes whether it is a kit or not, they don't sell kits for anything else.

Do you have a link? I'm not seeing anything for a mustang

Nah, I'm not replying to you anymore until you tell me why it matters, and why kind is the only tuner that needs to do the things you're saying

You don't have a link because it doesn't exist. Did you think I wasn't going to check...?

The only kits on their site are for WRXs and Nissan GTR's. Also take a quick look at the price of these things, This is what we'd be paying, maybe even more:

I have this system on my car, I built it and tuned it. If it wasn't for the help of another member who spent a lot of time getting custom brackets built I'd have some mickey mouse sensor bracket too.

The reality is Lund has to build a kit because of all of the reason I listed. Either they build a kit and spend tons of money developing and testing a kit, or they deal with endless customer support from users who botch the install and blame them for it.

Or they do what they are currently doing and make it your problem. They simply tune too many cars to deal with this.

The more I think it over the more I think they will only add support when someone else starts selling a full plug and play kit with no weird wiring.

Lund does offer Can Flex. I have it. Works fine, but also it’s really not that big of a difference from user-adjustable. The only time it comes into play is the first 10 minutes after a fill up. I understand a lot of you have some feelings about Lund (and some for good reasons), but if you’re going to make arguments at least try to be correct.

Also I think you all are grossly overstating how complex of an install it is. It took me an hour with basic tools and I’m no expert mechanic. Hardest part was getting the measurements correct splicing into the fuel line.

All in for parts was 400 for the Zeitronix bits, 50 for the OEM fuel line, another 50 or so for clamps, connectors, and fuses from Amazon.

Im just not arguing with someone who is arguing just to argue, it's a waste of my time

great.

This is I assume what you were talking about. It’s not a can bus kit.

There are no kits on the market that support PCMtec can bus flex. Lund would absolutely 100% have to make their own. So to this point

They need to make a kit, there is no kit for sale. All of what I said needs to be done, the difference is not just a drop down it’s an entire fuel system component.

you caught me when I had the time of day.
