I hope Dimitris got you straightened out. Your AFR table is problematic in several ways.

I will swap my basemaps over when I get home from work (weather permitting) Once I learn how to give props you have some coming your way Dimitris.

Why would my fuel table be so much lower than most peoples? Mine being the bottom 2 maps compared to Golferlukes? Using the new base map Dimitris gave me my AFR table is different but my VE Table is very similar to what it was.

Justin, don't worry about the VE numbers. They are dimensionless and work in conjunction with your "Req. Fuel" setting and the characteristics of your injectors. We all end up with different VE tables. All you need for VE is a starting point, which you already have.

Do endeavor to come up with a decent AFR target table. The AFR target table (along with your wideband readings) is the basis for either autotuning or tuning with MegaLog Viewer's tuning console.

Fuel tuning is ridiculously easy. It'll take me about 5 minutes to show you how to do it. Once you see it, it will make perfect sense. Sharing ignition tables and AFR target tables on the forum is a worthwhile endeavor. Sharing VE tables is a waste of time.

Looks like a great start to your build. I always like seeing more turbo miata's in Tx

I only touched the AFR table, use autotune in easy mode to get the VE table back in shape.

I was just showing you the shape difference between the ve tables, your numbers will probably be much different than mine, I'm running stock nb injectors atm.

I'm guessing my lower numbers are the bigger injectors punping out less fuel for my AFR target? Think I am starting to catch on.

Car runs and drives pretty "decent", good enough to get to your door Rick!

Not sure whether it's proper etiquette to post a first hand account on someone else's build.

Ahhh . . . what the heck.

Spent some quality time with Justin yesterday afternoon. I think he's over the steep initial MS learning curve. I expect he'll be one of the MS gurus in no time. It was cool to see the differences between MS1 and MS2.

We went for a drive. Nice build. Quality parts. I am especially impressed with that Artech exhaust. 3" but with a mellow, deep tone. Not loud at all. In fact, I'm so impressed that I'm going to get one for myself. Will be way better than the cludged up exhaust I'm running now. Curly, if you're reading this and you haven't already ordered one to uncork your exhaust, you shouldn't hesitate.

My latest PM from Justin has him running reliably to 15PSI and he's tuning away. I can't wait to see a new VD pull. His car is strong.

It's a lot of fun to actually meet some of you guys in person. My wife was laughing at me . . . "Oh, isn't that cute. They're doing carguy stuff."

I am reading this! Creepy. I have ordered a 3", great to hear another stellar review. It should be in the mail this week in fact.

Edit: tell us more about your ms1/ms2 experience. What you liked, what you didn't like.

Good to hear, time for videos

Rick, I appreciate all of your help and that you warmly welcomed me into your home. A deep deep learning curve has been accomplished this week and I can not wait to learn more about this EFI crap!

For my exhaust I have no complaints. I highly suggest anyone needing more umph and a great sounding exhaust to go with Abe's work. He really builds a piece of art, almost to nice to put on the car and not be displayed on my wall!

I will for sure be posting some videos soon. I still have some tuning to do to bump down my required fuel so I am focusing on that first. For now I am just going over the basics, running 12psi shooting for 15 tonight.

Rick has one sweet ride. Mine can not even compare to how well built his is. He did an amazing job with his build. The car is so smooth on and off throttle, hell even on our rough roads his suspension rides like a dream. I can not wait to get this car running perfect, I owe it all to Rick and you guys for sharing your knowledge helping us newbies out.

Rick, my next joy ride is the other silver mistress you have in the garage! I am looking forward to meeting up again soon.

for that turbo, yes. but fix the damn boost

FowlerMotorsports

iTrader: (8)

How does 15 sound Brain? This is still my learning turbo, it will suck once I have a bigger and better turbo, i will want to boost more and more

These are just some quick observations from a little bit of playing.

Dislikes: Nothing. It's an evolutionary improvement of the breed, just better all around. A better processor allows faster computation, larger tables for finer tuning resolution, more features, etc., etc. I'd imagine that MS3 is to MS2 as MS2 is to MS1.

Likes: These are some of the features I think are significant improvements because they were such a PITA to setup in MS1:

1. Idle with AC. There is a duty cycle increment that is triggered upon compressor engagement. Ahhhhhhh . . . . On the MS-1, this is such a pain. I've implemented spark table switching, additional air with the purge valve and even switched refrigerants to deal with this. And the whole time, all I needed was this one little feature! BTW, I'm not sure if this is standard MS fare or one of Dimitri's software tricks. But it's great.

2. Closed Loop EBC. The MS-1 algorithm is integral-only and takes some effort to setup (you have to intelligently switch between open and closed-loop control and tune both). The algorithm I saw on the MS-2 was true PID control. Much easier to setup and tune.

3. Two overboost protection limits. The MS-2 has two boost control tables available and each can be setup with an individual overboost limit. Nice if you're a dual fuel type.

I'll bet if I played with it more, there would be other things. But these are what popped out to me.

1 is available on my firmware and on gslender's firmware. Mine is a little more sophisticated.
2 is standard on all firmware versions
3 is only available on my firmware

This is partially why "hate" my simple car

1. No AC
2. No EBC
3. No need for duel boost limits

Although with MS2, I very well might add the EBC. Can the boost limit be change via software changes only? Like could I break in a clutch at 10 psi, then with the press of a button on my lap top have 15? This is of course assuming a wastegate-only pressure less than 10 psi.

Reverant

iTrader: (10)

Yes, it is possible, not through a click, but rather either load a different table for the EBC or switch to the second table through the external switch if you have an Enhanced MS2.

much much more fine tuning needed, adjusted my req_fuel and VE table so I am starting over with my fuel. Results aren't bad for a shitty tune, ignore the beginning I was shifting through gears.





No more tuning til tomorrow, time for my other other enjoyments

Someone's having fun. That torque curve is straightening out nicely.
