Car is tuned, dyno sheet
 

Below is the dyno sheet after Reveran't MS2 PNP was dyno tuned in my normally aspirated 2000 autocross car. I don't have a base pull with stock ECU. The person who tuned the car said that it looked pretty strong for a stock engine.

Can you post your msq? I would like to compare against some others I have collected for N/A. Thanks!

I can certainly post it a bit later on (it's on a different computer).

In the meantime, does result look OK? The tuning guy said their dyno is much more conservative than Dynojet, sometimes to the tune of 20% (hard to fathom and not all that important, but, hey).

Hm, 130whp is damn good for any N/A miata. Is this a vvt motor?

Either way great results.

Must feel nice. Now turbo it.

It's a bone stock untouched 48K miles engine in 2000 NB. So no VVT.

No turbo now or ever. This is autocross car. Autocross is the slowest for of racing with the largest rule book and some of the weirdest classing :) Since this is a CSP car it will stay NA. It might get a different intake, a different intake manifold, a different header, and get the cat out of the exhaust. That all might happen in two years when the car becomes exempt from OBD2 emissions reading.

(ducking and covering) I'm a supercharger guy :) Turbos are not my thing. Neither is power. My street car has 270 NA HP. Bleh. It's all about handling for me.

What's your street car? I'm curious now!

It's yellow :)

Here's a more Miata-appropriate pic:

A bone stock N/A NA 1.8 will consistently put down 96/92 hp/tq on the Dyno Dynamics at Ed York's shop. I don't know what the NBs usually put down but if your 2000 is bone stock with just a Megasquirt I'd say 132/120 hp/tq on a Dyno Dynamics is pretty good. Would be nice to see a comparison to the stock ECU but I'd be real happy with those numbers. What does your spark map look like?

That is fitting. If you don't like power, superchargers would naturally be more appealing than turbos.

130whp on a stock miata is kinda optimistic. whoever told you it was a "conservative" dyno is smoking some good stuff

Conservative is all relative, he may mean conservative compared to the numbers they run in the advertising department at Jackson Racing. It is a non-specific word, 130 seems pretty good for a 99/00 with a dyno tuned spark map according to other cars.

Food for thought:

Another N/A 1.8 at 131hp (non-99)
https://www.miataturbo.net/general-m...project-63125/

There was another post about a 1.8 N/A (non-99) I can't find, I think it was ~126

You have about as much power as the lowest level supercharger kits with band-aids for fuel and spark management.

I've tuned a buddy's fresh 99 engine (1.6 diypnp) in regionally competitive csp trim (stock intake manifold, RB header, stock bore, etc.) that put out 135hp on a mustang dyno. The stock ecu really is disgustingly conservative and leaves an easy 10hp on the table.
So his numbers aren't exactly unfeasible.

Thanks for comments, gentleman. A few thoughts:

1. The car currently has RB intake, RB header followed by OEM cat, Hushpower 2 muffler and turndown. Light flywheel which should not effect power output.

2. Conservative dyno, I believe, was in comparison to Dynojet, specifically. This is a mostly Subie rally shop and the dyno guy was talking about comparing numbers for the same cars between his dyno and other dynos. I think the discussion of 132 hp is richly irrelevant as this would be different on another dyno or another day, I'm sure. It's more than stock, which is a good thing. $1,300 project. We'll see this weekend what effect it had, if any, on an autocross course. If it buys me ).3 seconds I'll be happy. If it's 0.5 seconds I'll be ecstatic.

3. Let me know which files to export from MS with TunerStudio and I'll get you all the tables you desire :)

PS. There's power and there's power. For what I do (autocross) turbochargers are not ideal solution. I believe you know the reasons. Supercharger is better suited for that application. I would also gladly trade losing 30 lbs to gaining 30 hp. Turbos are fun, absolutely. But not for autocrossing. It's not just power, it's power delivery. At the right time.

PPS. I would like to publicly thank Reverant (Dimitris) for building this MS2 and answering my questions and Jess for selling it to me and patiently helping me over email and phone to put it in. Thanks, guys!

Those dynos typically read about 8% low. Those are great numbers for your set-up.

Nice numbers and curves!

Looking really good.

Saving your tune in TS will produce a file with a .msq file extension. The default file name has the date and time in it. It would be great if you could share it.

Tom, I should be able to grab the .msq file off the car by tomorrow and will post it. Anything else from teh project directory needed or is _all_ info in that .msq file?

Dimitris, thanks and a large part of that curve is your doing! Let's call anything below 4K RPM yours :) If you are ever in Boston in the summer beer and some autocross runs are on me. Oh, could you please let me know what can be done to get the temp to 220F (sent you an email yesterday) and also my question on knock sensor?

If you have had the computer with TunerStudio hooked up to the car previously, the tune should be the current one in TunerStudio - no need to hook it up to the ECU to save off the msq.

Unless someone else with a different computer has made changes to the ECU. In that case you need to hook up your own computer and will be prompted by TS to select which tune you would like to use - the one in the ECU or the one in TS. Then you should use the one in the ECU or it will get overwritten with whatever is in TS.

I hope that made sense :)

Just CurrentTune.msq from your project directory.

Tom, the person who dyno tuned the car was doing the tuning from his computer and his own Tuner Studio. I hooked up my laptop to the MS as I was driving home from tuning and, of course, chose "Use ECU tuning file" when it presented me with a choice of two files (yeah, I used to be an electrical engineer, but I often question my own sanity) :) I don't think that automatically saves the tuning file from ECU into "my project". Looking at creation date of my CurrentTune.msq file confirms that.

I can either wait till Monday to get the file from him or, I assume, simply hook up my laptop to MS, start Tuner Studio and click Save Tune As, correct?

BTW, being paranoid that I am, a few questions:

1. How long would it take to write a new .msq file into ECU? 10 seconds? 30 second? Does Tuner Studio give some warning like "Think of you are about to do, idiot!" or does it just do it?

2. I thought that it's possible to "lock" MS from any further updates. But I don't see it in any obvious place in Tuner Studio. I'd like to lock it so the file don't accidentally get overwritten (and, of course, I'll make several copies on USB sticks just in case).

3. Is _all_ tuning data contained in .msq file? Or is there something else in the project directory that needs to be saved, like settings that are additional to .msq file?

it does, everytime you connect/make changes.

correct.

use the newest TS firmware, what MS do you have? ms2? ms3? ms1?

ms3 = 2 sec
ms2 = 10-30sec
ms1 = 30-1min

should have a % loader countdown.

just save a copy of your tune that you'd like to save, keep the file handy.

just the msq.

Thanks, Brian! I have a Reverant built MS2.

Could you clarify point #1? If a file is burned into MS from laptop #1 and then laptop #2 is connected, would laptop #2 automatically get the ECU file saved onto its hard drive? It seems that it does not. Has to be done manually.

if you have dropbox on both laptops, simply save the megatune project in the dropbox folder. Each time you make changes on one laptop, it gets synchronised with the other laptop. Works a treat for me.

correct, but if you connect, without a difference between the offline and controller tune, then the tune will always update the currenttune.msq.

BTW, this is a very early Reverant built MS2 from the last group buy. Since knock sensor functionality is not on it, should I be concerned? I'm running 93 octane gas if that matters.

Also, the check engine light is blinking at exactly 200F. Is there an easy way to bump this up to 220F? Dimitris said that 220 is where it was set... I'm not sure why it's blinking at me at 200.

Knock should not be an issue if your tuning occurred under typical conditions and your tuner knows what he is doing. Only time will tell if you have any issues autocrossing, but I wouldn't worry too much- but don't ignore it.

I can't help with the check engine light, unless it is a software setting. If it is just software then you open generic outputs and change the CEL pin output to a different condition.

Looks like some great numbers for what's done to the car. I'm interested to see the spark map and compare to the bottom half of my map.

There are a lot of us out there running without a knock sensor. I've been running without one for several years now. I'm sure it's not the best case scenario but with a decent tune it should be fine.

OK, guys, attached is what appears to be in my MS right now. Please let me know any and all of your thoughts.

On a related note, please take a look at this blog and the dyno numbers and graphs towards the middle of the page: 1999 STR Mazda Miata Is this the difference between the two dynos? Or does that car really make that much power? Or is it crankshaft power?

Brian, could you double-check my logic, please, before I go nuts (have two autocrosses this weekend and want to think pleasant thoughts instead :) ).

Tuning was done on tuner's laptop. I got the car, drove it for about 20 minutes then hooked up my laptop. Let's say tuning was done by 2PM Tuesday, I connected my laptop at 3PM. File comparison came up with two tables. I've said "Use table in ECU" and drove about another 20 minutes looking at the gauges (didn't even go into VE analyze).

When I'm looking at the file I've posted above it has a time stamp of 3PM. Sounds about right, as you said the ECU contents would be written into CurrentTune file in this case. When I look at restore point, the only points available are 3PM on Tuesday and previous Friday when I drove with VE Analyze on to try to autotune the car a little.

Please confirm that I'm not insane yet. Or at least that CurrentTune file is what I got from the tuner. He'll send me his copy this upcoming Monday as well. Is there an easy way to compare his and mine .msq files?

Soft rev limit at 7800 and hard at 8000? And sure enough, your dyno sheet actually show that kind of revs - I didn't notice before.

Is that even safe on a stock engine?

EDIT: Does it idle well?

nile13, I took the liberty to repost your dyno output and grab these tables from the tune you uploaded. I hope you don't mind:

https://www.miataturbo.net/attachmen...ine=1342266247

I'm still amazed!

I don't mind at all.

Rev limiter should be safe based on my conversations with a number of autocross people. I've been running 7700 rpm redline for several years with overclocked stock ECU in this car.

It idles OK. I think it's a little more difficult to start, but since it's a daily driven car I don't really pay attention to those things.

once you downloaded his map, did you make any changes? no. then why would it update the file anytime after that. the currentune.msq mimics that of what's loaded. If the tune doesn't change, so don't the currentune.msq.

please read the TS manual to further understand how the offline file works.

Thanks for confirmation! I will certainly do some more reading of TS manual next week... if I can find it. I've read what's on EFI "Manuals" page, but can not see a full manual for the software. Could you please point me to it so I ask fewer stupid questions?

I know this is an older thread but it's my exact setup and use (autocross) except I daily drive. Have you had any issues with the tune? What octane did you use? The tuner I brought mine to seemed to be flaky and this tune might be what the doctor ordered. I wish I could PM nile13 but I just joined and don't have 15 posts yet. If someone could bring this to his attention, I would appreciate it!

Or if someone else used this tune, if you could chime in.

His tune looks fine to me. I have heard that peak power is at 30* at 101kpa on a 1.8, so that advance is a couple of degrees higher than I usually see, but some of that depends upon how accurately the base time was set at the CAS.

*from a spec Miata guy

Thanks, Sixshooter. Can you even set the timing on an 99-00 NB? I was under the impression you couldn't.

<NA owner doesn't know.

No problem, thanks for the help. I'm sure I'll be reading on here a lot (have been the last two weeks) since I am such a newb at tuning.

I started with this tune as my base map for my 99 swapped NA. I had to change the ignition settings for my CAS and 93 coil setup but it seems to be working well. I ran auto tune for the ve table and it seemed to improve my mpg without any noticeable drop in power. I started with 93 octane, then cautiously dropped to 91 then 89 octane and haven't noticed any audible pinging. I will say my motor is using lots of oil and I have a vvt motor waiting to go in so I wasn't too concerned about damaging it with low octane, but it seems to working well. I had to play with the idle settings and am still tweaking cold start.

Thanks for the info! What is your elevation? Have you dyno'd it yet?

I'm in the NYC metro area so I'm more or less at sea level. I haven't dynoed the car, but it definitely feels a lot stronger than it did with the 1.6 ecu.

Here's my '99 with a Reverent built MS2, tuned by Hustler. My car has stock intake, but RB header and Roadster Sport exhaust.

Just to update, it seems to not like the 87 octane too much, as I did hear some slight pinging under certain conditions. Will try a tank of 89.

I tried the tune over the weekend and my car didn't like it so much. I think it is running too rich by the smell, which I'm fine with if that's max power but it felt slower. Is it because I'm at such a high altitude (4500 ft) that the afr/fuel tables are off? I am a newbie at tuning so if someone thinks otherwise, let me know.

I kept 99% of the settings but went back to my original tuner's afr/fuel/spark tables (which was a disappointing tune originally).

Based on fuel consumption, my car was initially running a bit rich as well. I ran autotune and it seemed to bring it to normal.

It looks like that graph says engine power, leading me to question the correction factor which isn't readily apparent in the graph. Do you have any idea what correction factor may have been used?

I don't know the answer to that. I know that it was a Mustang Dyno, and that it reads low compared to others. Maybe Hustler will see this and chime in... but it's been almost a year since the dyno session...

Thanks so much for the help everyone. I am learning a ton!

I noticed that this AFR map goes to 100 % load. For a N/A is this what the target should be. My tuner looks to have taken the stock table and used 200% as the max. Does that mean my car really is only using 1/2 the table and thus is not getting fine-tuned settings?

I did a log the other night and my max MAP was 89. How do you find the max load % you should use?

Tune in the Northeast
 

Can anyone recommend a reputable dyno tune shop in the Northeast? NH, MA , RI, CT. With MS / Miata experience. Dent Sport was the choice until they closed last year.
