Default Anybody here tune/work with a Speeduino?

Before I get flamed, I do believe in spending money on where it counts. I owned a MS3Pro for a reason. Over on Facebook, Speeduino is consistently recommended as an equal that fits between a ms2 and a ms3 for a fraction of the price. Some even advocate a MS isn't worth the money any longer. Have anybody here tune a Speeduino that can either state otherwise? The MS3 is expensive for a reason whether it's the addition features you get (VVT, E85, additional inputs/outputs), or its superior programming (flex fuel and idle controls) but how does it compare to the Speeduino? I would like to have some facts and professional opinions when I try to steer people towards a MS without talking outta my ***.

Download the firmware and base tune. Open them in Tuner Studios and check it out. At least I am pretty sure that they use TS for tuning.

They do. Just built one to handle fuel and ignition in parallel with the factory ecu on my f150. Wouldn't recommend running one as a stand alone. Not enough options for things like idle tuning.

Definitely won't be replacing my stand alone MS3X in my miata.

That's the kind of information I wanted to know. Reading the basic functions list provided by the Speeduino designer doesn't really give the whole story. a MS2 can do flex fuel but many people don't recommend it because it's not really great compared to a ms3. A speeduino can do flex fuel mapping as well but... you don't really know how well it works until you actually use it.

The problem with flex fuel on both platforms is the inability to blend tables. I don't want to be stuck adding 10 degrees across my entire ignition table. I want less than that at idle and more than that in other areas. I also want to target different air fuel ratios based on ethanol content. If you want to do flex properly you need a MS3.

I have one of the first beta MX5 PNP boards in my daily N/A NA.. no major issues. yes it lacks a lot of options and settings but it gets the job done for a 25yo engine with no added options or devices.

you get what you pay for and I LOVE the open source-ness. don't like something or want to add a function? dig in the arduino code and DYI!

Default Hmm...

I’ve been studying the speeduino Fb and wiki. I never plan to turbo, so wondering if the speeduino is worth a few ponies, since it allows for adjustability of mods, timing, fuel, as well as getting rid of the maf.
For 350$ all in, you can’t beat that adjustability. I really wanna pick it up for a set of ITBs.

SpeedyEFI is making and selling pnp units for all years and a 01-05 compatible one for 475$. That's a stupidly good deal if this ecu can manage a BP with reasonable results. I don't expect it to be at an ms3 level.

Link? I only see a 90-93 PnP.

The killer deal is the ability to build one yourself for $200. All appeal is lost for me at $475.

You have to contact him directly for anything other than na6 ecu's.

wow. very inexpensive option.
I am not looking for all the bells and whistles on a MS3.

so a 300$ price point for a tuneable PNP ECU is very attractive..

MS should come up with a simpler micro squirt.
that doesnt do everything.
but comes in at 300-400$.

Just remember that with anything you get what you pay for but you never get what you dont pay for. Sure MS3 is fairly expensive but the options and abilities it has are good. You may decide "I'm never turbo charging the car" now but what happens lets say two years from now when you're bored with it and want more? Or doing a VVT swap? It seems to me that having the ability to now will allow the option later on if you change your mind.

Why not just build an MS2/3 for slightly more than the Speeduino unit? If you were willing to buy a 200 dollar DIY unit, spending a few extra hundred wouldn't hurt.

FWIW I ran a Haltech Sprint 500 ECU in my 90 before going to MS3Pro and haven't looked back. I also have that Haltech ECU for sale with a Boomslang adapter harness to plug and play in a 1.6 if you're interested.

For 200 € it's unbeatable.
Has VVT support, flex fuel, boost control, launch control, flatshift, good resolution - everything the noob needs.

I own one myself (turbo car) and got it running okay in an hour.

Next options in Europe are MS3 mini and ME221, both starting at ~600+ €.

Why not just build an MS3 for slightly more than the assembled Speeduino unit? If you were willing to buy a 200 dollar DIY unit, spending a few extra hundred wouldn't hurt.

the problem is the amount of features I pay for ms3, and then won’t use, even if I turbo later. Never looking for more than 200hp. Speedy does this well and for way under budget.

I'm running a na6 pnp speedyefi speeduino. It works great and is easy to tune for beginners. I use ts, an aem wideband, a gm sensor, a bmw vtps and the pnp adapters. My car definitely gained some butt dyno hp. its worth what they ask for. if you're not looking to make 350+ hp, I don't see why you wouldn't want to use this unit.

Did you know the MS3 has 2 separate progressive nitrous controllers?.. and sequential fuel injection and COP support for V12 engines?
nothing want to use or plan to use or want to pay for.

i plan to go the speediuno option very soon and will post play by play results.
Just looking to remove the AFM and go COP on my 1.6 . If i gain 5-10 HP doing so then it will be the greatest 350$ you can spend on a 1.6 for power.

I wouldn't put the MS3 and a Speeduino in the same category, more considering a comparison between betwee a ms2 and speeduino. A MS2 is still 2.5x the price but function wise, how similar (or different) are they.

I could've googled the features myself to get that list but just because it can do something doesn't mean it can do it well. That was the original point of me creating this thread. In a real world scenario, how does it actually preform. I am actually thinking about using this in my EG Hatch budget build. $300 ecu vs a $700 hondata which is why I want to know.
