Ok here are my dyno charts, the first one shows the Softronic 3.x tuning and the 4.1 tuning overlayed. Basically there was no meaningful difference between the two as the lines intertwined. I asked the dyno operator about that and he said all sorts of misc factors cause that sort of intertwining, anything from ecu voltage fluctuations to wheel hop. In his opinion, and mine, you can call these two a dead heat. Now I should also say that I don't think Softronic advertises 4.1 as a hp/torque increaser but rather it addresses some other items, but still I was curious and wanted to see if it had any effect on my car. Keep in mind my car is heavily modified and so your results on your own car may vary.

The next 2 dyno charts also show the exact same dyno run but show with 2 different filters applied, the first one has a filter value of 6, the second of 50, notice how the numbers at the bottom of the chart change as well. I was there next to the dyno screen when this run was made and the dyno showed 334.0 hp and 265.4 ft/lbs of torque. Those numbers changed on the charts though depending upon what filter was being applied. My max HP was achieved at 6,950 rpm and then tapered off over 7000 to the stop point of 7500 where we collected, the chart only shows up to the 7000 mark as the operator forgot to carry the chart out further, but I can tell you there wasn't any miraculous sudden jump in hp at 7300 or anything.

FILTER = 6

FILTER = 50

If you have any questions let me know. As far as "driving" the 4.1 vs. the 3.x it seems pretty much the same to me with a couple of small differences. First, it seems a little easier to get away from a stoplight and second, the whole engine seems a little quieter/smoother, which I know doesn't mean much to anyone else but to me it was something I noticed, almost if it wasn't working as hard, or at least not sounding as if it were working as hard to achieve the same results. YMMV!

I've now spent a couple of hours driving the car and can say the following:

1) idle is smoother
2) off line acceleration is smoother
3) mid range acceleration is both more powerful and smoother (2K-5k)

Car is quicker, I put it to my usual run test and I was nearly 3 mph faster than I had been before, so much so that I've basically run out of room to be able to brake and still make my turn!

While the dyno shows that under WOT the power is the same, I'm always easing into the gas from the start trying to find the best take off without breaking the tires loose and getting wheel hop, etc. I think this flash made it easier to get a better launch and the launch probably account for most of that time improvement, that and the lighter wheels and tires removing weight along with the additional hp, it is "all good" as they say.

2 Thumbs up for the 4.1 Flash.

Thank you for the detailed feedback. I look forward to receiving Scott's upgrade and experiencing the difference myself.

Hi Ken,

I noticed the "smoothness" also and started a thread about it a few days
ago. THe best answer so far is from someone who said it was the SW
that made the difference (SRP plenum with stock tune had rough behaviour)
- and I see you're confirming it.

So do tell - what are your current "go fast" mods now? If I recall correctly
it's basically:

SRP 4.1
Capristo

Cheers,
W.

I can hardly wait for my 4.1 tune.....I must be patient!!!

Umm no, have you clicked on my garage link and looked at my list of mods?

Great info Ken.

Hello All,

I will be sending files out with the 4.1 for the 2006 cars starting tonight. This version for the 2006 cars was made to address driving with operation up to 99% throttle and closed loop lamda.
Dyno's all are run full throttle in which are open loop and the fuel is pre defined with timing. This correction had been made with version 3.1 and above. What I changed was not necessarily the max HP and torque yet the entire driving experience. This would include mid and lower range acceleration, Idle, city and cruising constants and basically improved the other 99% percent of the driving experience.

Lets be realistic you do not start the car and drive from point A to B with full throttle and then all brake and back again, well some may

.

Note: This version would show an HP increase over 3.0 and lower versions and a significant driving experience all around from all versions..

Best Regards,
Scott Slauson

Nice description of what you are thinking in terms of drivability. Looking forward to getting the 4.1.
Thanks--

I don't even think with the X51 (GT3throttlebody) I will reach numbers like you. If you get the X51 you will pass GT3HP (415) you need to get the X51 intake, and finally add the GT3 grill while your at it

**K-Man S** · #11 04-06-2009, 11:45 AM

Well it is currently the most powerful naturally aspirated 3.4L Cayman verified to exist.

Of course that means didly squat when a Koenigsegg pulls up next to me...

you need to get the X51 and you will devour GT3 and GT3RS' all day
we basically have the same power mods just different brands:
-pulleys
-full exhaust
-softronic software -not dynoed yet
-GT3 throttlebody -not dynoed yet
-intake (K&N) you have Evo
-plenums (I have the X51

) - not dynoed yet

I have a V-Flow and SRP with 4.1.

Given the figures I've seen above and what porsches4ed reports, would an UD Pulley and full Capristo exhaust really give me > 360bhp?

With my mods I managed a 6.2 sec 60-100mph time, measured using a G-timer. This was down from 6.9 sec before any mods.

In terms of performance mods Ken, you have:

SRP (80mm TB) with 4.1 software
BBI UD Pulley
Full Capristo Exhaust
EVOMS V-flow
Engine Internals re-balanced

Are these all of the power yielding mods?

390+ HP is some gain!! Have you ever measured the in gear times?

Cheers

Chris

I beg to differ, and as we know, one cant compare dynos.

I had a run against a 911 turbo the other day with a 80kph rolling start. Dropped it back to 3rd, and he could not overtake me and I held the lead untill we both backed off. Nuff said...

yeah but that's all hearsay, I mean come on I've toasted 996 and 997 turbos at the track, but that isn't anything tangible or repeatable. You could also achieve the same results say by stripping out a Cayman like Fort Felker has done and that wouldn't have anything to do with power.

While true you cannot compare dynos, I can say I haven't seen a valid dyno run on any dyno of a 3.4L naturally aspirated engine higher than mine.

Besides this is all in fun anyway... as for power mods I have the following:

De-Snork
EVO intake (probably with a dirty filter again too, I need to check that)

SRP and 4.1 software
Capristo controlled intake/balance flap
Balanced and strengthened engine internals
UDP
Capristo headers
Capristo catback exhaust with updated new style control box
RS-98 lightweight wheels and tires (actually lowers dyno numbers vs. my other wheels and tires, but not by a lot)
Turboencabulator Mark III Rev 2.(a)
Phase shifted force responsive dark matter focus ring

I think that about sums it up...

**4by4** · #16 04-07-2009, 12:50 AM

I have a freshly cleaned "pretty in pink" EVO filter and that does make a difference, esp if your looks like a block of chocolate.

Pretty well the same mods between us.
Currently:
1. "De-snork".
2. Milltek Race headers & Milltek Cat Back.
3. Freshly cleaned Evo V-flow filter.
4. Softronic Flash v4.1.
5. Porsche Plenum.
6. Oversize Plenum hose.
7. BBI UDP.
8. 80mm Throttle body.
9. Yokohama Advan RS rims (when fitted)

The Yoko wheel and Dunlop tyre combo when fitted definitely gives me more acceleration owing to the effective lower final gearing.
Before I could just pull 0.7Gs' in first, now with the new flash and these wheels I can get 0.73 Gs'. Im yet to test the effect of the 4.1 flash by itself.

Me in the middle at the track, the yellow turbo is on the left.

My filter is clean, and my engine has 16,000miles. I am planning on doing an engine balance too and as soon as I finish adding my flux capacitor and Dennis Lee PICC exhaust system PICC I will have the highest dyno numbers on a NA 3.4L, or maybe I should just dyno at Imagine Auto ZAAAM!!!

Jesus Christ ed, that PICC link you gave is an eye-bleeder. I've been working on engine testing and combustion for quite a while and I've never seen such quality ***-wipe...

"...what if we “cracked” the gas and broke it down into smaller particles before it went into the engine — not after the engine had wasted it? Everything you would otherwise be throwing away would now be burned IN YOUR ENGINE..."

OF COURSE! LET'S APPLY SOME ELECTRICITY TO GASOLINE AND TURN IT INTO MAGIC, that not only DOUBLES it's calorific value, it also EMITS NOTHING! I wonder what kind of a$$hat retard scientist they had on the other side at the court hearing to conclude in a successful case.

In other news, I hear snakeoil works wonders in improving gas mileage if used instead of the Mobil1 **** the Porsche OPC puts in your cars JUST SO THE FAT CATS GET FATTER!

Sorry for getting off topic, lets get back to the Softronic software.
