Two ways to do this off the top of my head.

The cheap way(maybe). Get a 5.0 cam sync, 3.8l v6 cam sync, and a 351c/460 distributor gear. dissasemble both cam syncs, and put the 3.8l shaft into the 5.0l housing. install the collar onto the shaft, then all you need to do is install the cam gear on to the correct depth and redrill the rollpin hole.

The Expensive way(maybe). Give pricemotorsports.com a call. They make a custom one that uses the factory sensors, so its a plug and play situation. they are just on the expensive side.

But depending on what you end up paying for the individual parts to build one yourself, plus your time. It may have been cheaper to get the one from price motorsports.

FYI, The only difference between a 351w and a 351c/460 distributor is the cam gear. the 351c/460 use a larger diameter gear. Otherwise they are the same.

Thank you for this. I've been doing as much reading as I could on the Ecoboom calibrations, but i'm a few generations behind. This made figuring out what controlled what a bit difficult.

One of these days i'd really like to find someone that can sit down and show me what all controls what. Between electronic throttle control, variable cam timing, torque limits, inferred map, mapped points, etc... im a bit out of my element.

Do you know of any resources that could help me understand the newer strategies better?

Not sure if you mess with the ecoboosts much, but i have a coworker that wants his car tuned. He has gotten a few remote tunes, but isnt happy with any of them. With how complicated the newer stuff appears to be im not exactly sure where to start and what needs to be tweaked to get what he wants. Im hoping you might have a base tune i can start with, and maybe a crash course on what controls what? Ill attach both of his remote tunes he got.

The first file was a supposed performance tune. boost was upped to 22psi, but fueling was all over the place. it would randomly drop into the 9:1 afrs, trims would be fighting themselves, lots of black smoke, etc... overall he hated this tune.

The second was an economy tune, no performance increase that he could feel as thats not what it was supposed to do. But, his fueling is damn near spot on from what we can see. No more rich spikes and no more fuel trim battle royale. This tune runs better than the OEM tune did.

One thing im afraid of is the possibility of having to redo part of the SD model. The car was a salvage car, and he had to replace all of the charge piping and the downpipe. He went with aftermarket parts because at the time, they were cheaper and easier to get than oem parts. Im worried this may be causing some differences in the airflow model and is part of why his fueling is off even with the OE calibration.

The strategy is SGMN0S9

Thank you!

Give this a shot

nah i dont have HP Tuners, just the demo. Im using SCT and whenever CoreTuning releases the strat BE. The version of SCT i have doesnt have a calculator built in. BE Does, but again they dont have this specific strat available at the moment. May have to just export my bin from SCT and import it into HPT to use the calculator, then export back to SCT. I got a pretty good explanation in a discord group how mapped points and the quadratic SD model works, so i think i have a good starting point on how to go from here.

Hello,

I am getting ready to work on a 15 Mustang 2.3l Ecoboost, and looking over the tune, im trying to figure how to correct the SD model. Im not used to anything this new, so im not up on how the mapped points are selected or how to recalculate the quadratic SD. Any help/advice you have as i dive into the deep end?

Thanks.

I am also looking for directives to study. Ive been trying to learn how to do this, but not having any programming experience, I have a hard time understanding what each subroutine is actually trying to do. Having a few of these to look at and compare to the one I am trying to work on could help me (and probably most other people learning) understand what and how these work. Could lead to a larger pool of signature based identification in things like SAD.

I know most people that can and do disassembly and strategy development, dont want to give away their hard work. So thats usually why i havent seen much in the way of this kind of information. This is a shame though, as the community could go alot further to having more free defs, and possibly more people to help in developing strategies.

In the getting started writeup you say that the 2 bank are able to be read, just not written with PCMflash. BUT, i just got the software and was testing with some of my spare processors, and found that i am unable to even read the 2 bank boxes. is there something im missing? it only gives me an option for the 4 bank and a few others that dont apply (probably euro boxes). If i try that option it says unsuccessful.

Not going to go digging the bowels of the internet to find something that should be simple to find. Cached pages on search engines don't stay cached forever. They aren't the internet archives way back machine. A convoluted solution to a simple problem.

But since we are on the topic of site updates, when are you going to update your homepage? The 90s called, they want their internet design back. Bandwidth isn't much of a concern these days. I moved up to a small mountain town where I have no cell data, but have internet that rivaled what I had when I lived in a big city. You don't even need to go to something like WordPress, just an actual unified page layout across all sub-pages. It takes no extra bandwidth or server overhead to implement css to handle page style and formatting. And once you make your one css file, all you have to do is link each page to that and it will auto format everything for you.
