Thank you for inquiring about our products. While many of the products we sell may fit other Ford-powered vehicles, we solely specialize in 1979 to current Mustangs and SVT Lightning. To best answer questions about non 79 to current Mustangs and SVT Lightning, we would suggest you try internet forums specific to your vehicle or even some internet searching. We believe heavily in customer service and would hate to give you incorrect information due to us not being experts for your vehicle.

[@REALGAMER29]

Can I use this to do my maf conversion ?? On my 87 5.0 ? And not have to buy a 88-93 pcm ??

[@latemodelrestoration]

If you were to install the MegaSquirt ECU, a MAF conversion would not be required. If you want to retain MAF and install a standalone ECU, then you should consider a system from Pro-M. The Pro-M stuff is substantially more expensive, but you do get everything you need to complete the install. Let me know if you have any questions. -Landan Pro-M ECUs: lmr.com/products/79-93-Mustang-Computers-Controls

[@angry408w7]

Not to mention the time saved setting up and driving the vehicle. The shop who does "tuning" gets anywhere from $250-$1000 ranging from a simple retune to a complete tune. If you were to change heads guess what? Pay for retune. Change intake? Pay for retune. And on and on.

[@hectorgomez502]

You can still connect a maf to these systems if you want to use one.

[@hereinmissoula11]

You know you're in trouble when the instructions start with: "First, disassemble half your Mustang..." Did you see the size of that instruction manual?

[@gamalielcruz]

Will this ecu work with a 351w

[@latemodelrestoration]

In a Fox Mustang, yes. You'll just have to change the displacement and adjust the parameters according to your setup. -Landan

@@latemodelrestoration thanks as I’ve been contemplating the swap for a while. This information just further enticed me to do the swap.

Can you please tell me the size of the wheels on that car!

[@latemodelrestoration]

Jonathan, that car is running our series 3 wheels, the front is a 265/35R18 on an 18x9 and the rear is a 285/35R18 on an 18x10! Some modifications may need to be done to clear these on a fox. You will need to roll fender lips and remove quad shocks and tail pipe modification may need to be done depending on your setup and you will need an SN95 5 lug conversion and steering rack limiters upfront.

The body panels started in 1979. Why does “Fox body” start in 1986? I had a 1985 GT which was the last year for the Holley carb. Does that have something to do with it? EDIT: Never mind..... I just found the video, “What is a Fox body Mustang?”

[@houseofno]

This has nothing to do with body panels. this is for factory EFI 5.0 cars. The Mustang didn't get factory multiport fuel injection for the 5.0 V8 until 1986, NOT 1979. Might help if you actually watched the video. This isn't meant to be a documentary on the Fox body Mustang.

Speed density is better for boost that's why it uses it over mass air

[@jsfetters]

@Richard Skipper lol a guess vs knowing. MAF wins every time in the knowing category.

[@hectorgomez502]

Both work, and Megasquirt can use both calculation methods. The best part is that you can use just about any maf. I have a newer GT500 maf in a fox body connected to megasquirt in a standard 3" tube that works great. My other megasquirt fox is speed density and also works fine. Just two different means to an end.

@T Web there's a lot of quality that goes into the system and a lot of people smarter than me know the in and outs. Did Snow performance close up shop when Matt Snow stepped down? Nope. The quality is excellent and the system is extremely user friendly and that makes it more popular everyday. If Chris Richards-the owner, steps down, I'm sure the pro m will be around for a long time. Order one and find out for yourself 😁 or spend days on end trying to figure out the mega squirt and Holley. I can go from a stock 302 to a blown 408 with absolutely no Dyno or tuner whatsoever.

[@TheCobraClone58]

I agree with you 100 %. Pro m efi is the way to go.

[@Texas_Road_Warrior]

The megasquirt guys have the most knowledgeable and competent tech support... there’s countless forums and tuning tips all over the place... any tuning software is gonna be complicated if you’re doing it yourself...

[@angry408w7]

Absolutely agree. But with the pro m, you don't have to go searching for countless forums for the information you need. If you can follow the directions, you can have your car running and driving very quickly. Usually within the hour.

[@jerryhoffmann2918]

1 hour is about what this takes, less if you're good. This video is awesome, and goes into detail and extra steps in the name of helping anyone be able to be successful, but some of those steps are not needed if you know your way around your car. I've never removed the airbox to run the vacuum line for example... though it is tight up in there it's doable. That said, it's hard to make a video that perfectly meets everyone where they are at, and LMR did a great job I think!
