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!

nile13

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.

nile13

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)

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?

one-niner

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.
