$1000-$1300 for an aftermarket SEFI upgrade? Pretty pricey.
And he's saing selling the MAF parts paid for it "completely"? Last I saw a harness, MAF, and used computer aren't anywhere near that much.
Along with bashing the MAF conversion that so many people say works so well... You sure you don't maybe work for these guys?

By NO MEANS!!!! Am I bashing the MAF kit from Ford (the only one I used), it worked great until I got into crazy mods!!!!! For a stock or average street modified setup, it worked great...but, you missed that I had an aftermarket tuning kit. The TwEECer is a bit pricey. And there also, I am not bashing that! The TwEECer is pretty cool but more complicated by miles for me. I am an enginer with a hobby of playing with my truck....I don't even work in the car industry so implying that is just plain crazy but you didn't know so no big deal. I have just been done right by them and am sharing my experiences...look, there are a lot of right ways to do things, I have experience with several and was sharing positive experiences. As an engineer and a hobbiest that has had success with a product I felt qualified to share...It was only my opinion too, close minded to a different approach? By the way, I exxaggerated a tad, it cost me 147 bucks out of pocket over and above all the other tuning crap I bought...MAF, TwEECer, MSD boost retard module, and several other electronics and instrumentation add ons.

As for price, buy one good MAF (Pro-M), TwEECer, a laptop, boost retard controls and you just spent more. I am running boost so I made out great.
I think it looks great...nice to see other options.

I don't understand why you had so many problems tuning your rig with that Tweecer. While the software itself is a bit of a challenge to learn, I've seen many people use it with great success; speed density and mass air application with nitrous and/or turbo or blower.
I've been doing my own tuning for 2.5 years now (14psi, with speed density and now with mass air) and I haven't had too many problems with it thus far, and I'm using SCT Advantage software.

Hey Blurry94, I didn't mind the TwEECer and I even liked parts of it. I just had driveability and constency problems with it. I don't know why, but I got fed up dealing with it...I didn't want a piggy back. I have seen VERY successful rides run on it (as it sounds yours is) but just wanted the power of a stand alone. It more consistently provides performance that is tuneable at the touch of the controller....must admit, I would go to another stand alone if I had a mustang for racing but I would still go stand alone again. I definitely don't want to "bad-mouth" the piggy back controllers....just had some VERY negative experiences even after I had a full understanding of the systems.

Found this link same stuff, it would seem they have some pretty high performance success with this system.

Looking at it again, I guess it is fairly inexpensive for a standalone kit, although megasquirt might have an advantage there. I'm used to having a graphical view of the fuel and ignition maps, which is why I think it would be hard for me to get used to the small LCD display. I'm sure adjusting to it isn't hard, I just think it would take a lot of getting used to for me.

Once Megasquirt gets all of the bugs worked out, it'll be an excellent stand-alone for a mild to wild build.
Me personally, for a mainly street driven rig, aftermarket tuning software (for stock EFI systems) will help tie all of the aftermarket parts together, and still have good street manners. Just select the tuning software (SCT, Tweecer, Tuner Pro or EEC Tuner) that best fits your needs, and/or chip tuner and all will be fine.

I was going to mention the Megasquirt kit!!! That one excites me a lot....I almost went that route when I bought the SDSEFI....I chose not too only because of time. I will, within the next two months be building a Megasquirt just to do it. Will probably run it on my dad's 5.8. Just got married so I have to get situated with the wife before I play with circuit boards.
I do agree that for street rides the tuners are a great option. escpecially the systems (SCT) that have really worked to develop a user friendly software.

I have 93 Bronco 351W w/E40D. I use the truck for 'Street Class' in the local mud bog competition and am planning on modifying the engine for performance gains. Am considering the MAF conversion but the E40D seems to be a stumbling block. I have heard the SD system can be retained & still be able to make reasonable power from the 351. I would like to be somewhere in the 400-550 HP range. Any help is appreciated.

I'm not sure how serious you are into mud bogging, but dumping the E4OD and going with a C6 would lightnen up your rig and a mass air conversion would be a little easier to do.

I may eventually go to the C-6/9" combo but I am currently running the "Street" class and do use the truck once or twice a week for commuting because I enjoy driving it (a/c & all still functional) and the OD transmission allows me to run the 488's & 38.5 Boggers and still get on the highway. I'm looking at the SDS Injection kit from WMS Racing as an alternate to MAF conversion. Supposedly it will allow you to do upgrades & retain the SD system but I'm not sure if it handles the E40D. Anyway, maybe I'm looking for the impossible but I've never been a believer in impossible.
