I think the SST Sport program is too far more sporty than normal. If I am cruising in normal mode in 4th gear, when I switch to sport it become 2nd gear in the same speed, too much engine braking/high RPM for me. Has anybody able to reprogram the SST?
They don't have to make the sport mode too sporty, as there still the S-Sport mode. I want to use sport as default mode when driving, normal for fuel saver, S-Sport for the track.

I agree that in the auto setting they both have way too aggressive shift points for the street, but those modes in full auto were meant for the track. The solution for the rpm control is to shift manually in either Sport or S-Sport instead. Gotta love how it feels with higher boost peaks in both Sport and S-Sport. In Normal the boost is too low. :)

In more than 30 dyno runs with my MR X I have never seen any difference in peak boost between Normal, Sport and S-Sport. We did a set of six runs initially just to determine which gearbox mode would be best for our dyno runs and after two runs in each mode found that the boost levels did not change at all.

yeah i was gonna say, i don't see how what setting the transmission is in would effect the b00st.

The fact that the sport and S-sport settings keep a lower gear, higher RPMs, may give the impression of more boost in a daily driving situation.

Hmm, very interesting. The guys in the article linked in this thread claims the opposite? http://www.evoxforums.com/forums/showthread.php?t=4970 What mods were on the car when you dynoed?

Does anyone know if there's anything formally written up that's lists exactly what the ECU really does between those settings besides changing shift points? For example, it obviously clamps down harder with less shift delay in S-Sport.

That thread that mentions the "report" was started on June 01, three weeks before the first USA MR was actually on shore. If you read down through the thread you linked to above, you'll see several posters that indicate the "report" is not accurate and their own results are in agreement with my statement above. I suspect that "report" was written from pre-release sales literature and is more marketing than fact.

I started dyno testing my MR X as a completely stock car, with slightly under 1500 miles on the clock. Peak boost was recorded at 23.5 PSIG, with all six pulls within 0.25 PSIG of that value. Then assorted mods began, with dyno runs after each change.

There is a significant difference in throttle response between "Normal", "Sport" and "S-Sport" that is very notiocable when driving but that never shows up on the dyno as the throttle is held wide open for the pull.

Cool, thanks for the additional details. It must be the different throttle response I'm feeling then. I asked about this over at the Perrin thread as well and they also said that it makes same power in all settings while it's the throttle response that changes. So I learned something new. :thumbup:

So I learned something new. Party On, Wayne!!

if you didnt want to get a sporty car shoulda bought a lancer :P

Funny thing for me is mine feels faster in sport mode than in S sport mode. In S sport it keeps the RPM so high that it barely makes 16psi most the time. Feels weaker to me on the street. From a dead stop is another story but actual driving sport feels best on mine as it will hit 20-23psi most the time.

Agreed on this last point!!! Powerband ISN'T found up at 7500RPM! :-P

So which gearbox mode do you recommend for dyno runs in an MR; Manual or Auto and in which of the three modes? Oh, and in which gear; 3rd or 4th?

Manual mode for sure. That way the RPMS will still stay high for a moment after the throttle is lifted - it won't upshift, and you can hold the gear. Keeping the revs up for a few seconds after the throttle is closed on the dyno keeps the engine oiling the hotter head areas so the engine can live a longer, better, more productive life.

If you kept it in auto mode, it would downshift on WOT and you wouldn't be able to test the low-RPM section.

Use any mode you want as they will all produce the same results. All of my pulls were done in third gear just to keep the speed of the rollers down to a reasonable level.

Cool, thanks for the info!

Man! Finally! I've been looking for this thread!

I recently put my MR up on a dyno to find out some numbers. I found out something interesting as well!

We did 3 pulls in all 3 modes. The real surprise? S-Sport and Normal produced higher numbers and better curves than Sport mode! The highest was S-Sport putting down about 3whp higher and 20ft/lb torque more than normal. Even more interesting for me was that Sport actually put down almost 18whp LESS than the other modes!

I will post the dyno graphs later I hope now that I found this thread again.

(I will be taking the MR again to a Dyno after prep for E-85, and will have them run all 3 modes again if possible to see if I get the same results.)

One thing i've noticed about the SST is the throttle mapping. In manual mode, switch from normal to sport, it will feel as though you are pressing down on the gas pedal more even though you are not. So if you were at 50% TPS in Normal and switched to Sport, then that 50% is now like 55-60% even though you foot hasn't moved. The percentages i used is just an example, i don't know the exact ratios.

Excellent observation ..

SPORT increases approx 3-5% compared to normal
S-SPORT increases approx 8-10% compared to normal ..
That accounts for most of the perceptions that SPORT /S-SPORT is faster and has more hp than normal .. ;)
