No_OBsT33RS Gear Tuner Calculator BETA V 1.00

[No_OBsT33R]

No_OBsT33RS Gear Tuner Calculator BETA

This is the Gear Tuner Ive put together. Its a BETA version and while Ive tested it on MANY cars there still may be some that cause an issue, if you find any please report them back.

INSTRUCTIONS ARE INCLUDED IN THE READ ME FILE

This is a SIMPLE Gear Tuner for OPTIMUM Gear Spacing for the Cars Max Speed Ability. There will always be a margin or error, usually around 1 to 2mph.

I will include a TRACK Tuner in the Full Release. This will allow you to tune the gears for specific Tracks adjusting your max speed per gear.

This is an Excel Doc

Post any Questions you may have. Keep in mind this is FREE.

Does it work on ipod touch? Im on itbknow but cant download it

 

[kebabs]

Is this only available for pc, cant see attachment on phone

 

[No_OBsT33R]

Does it work on ipod touch? Im on itbknow but cant download it

Might with docs to go ill have to try, but as is its for excell.

Its viewable on Docs2Go, I'm not buying the full version of Docs2Go to see if its going to work, but looks like it should.

The Calc should work on any car with a tuneable 6speed.

First Step is to use the IN GAME Top Speed Tuner and or Final Drive Gear adjustments to reach the vehicles rough top speed at the rev limiter. Once you have established the "rough" top speed enter the Data into the BASELINE TEST Fields.

Why at the rev limiter? Wouldn't it be better at the peak power?

Example:
Mazda Autozam

-The engine revs till 10'500RPM, but the best is to shift at 8500, cause the performance leaves much at these high revs.

Example:
Mazda Autozam

-The engine revs till 10'500RPM, but the best is to shift at 8500, cause the performance leaves much at these high revs.

2 reasons.

First up its gaging the rolling resistance for the calculations. If you notice it will display the max speed for each gear (catch up PD) it also confirms my acceleration calculations are correct.

Second is that it tunes the gears, shift points will still need be calculated (ive got a calc for that in the works) However the gains from using calculated shift points are negligible (while still noticeable) As tested and confirmed GT5 acceleration rate is NOT impacted at all by the torque curve (this is with all the cars I've tested, I'm open to test any car somebody feels will yeild different results). Acceleration in each gear is steady to redline, at redline there is a slight drop but not enough to gear it lower.

 

[dr_slump]

But the problem is that I can't hit the redline at high speed with the Autozam.

For the baseline test adjust the FD until you max at rev limiter in 6th gear.

In each gear before 6th does the car accelerate to rev limiter or does it stop at 8500rpm?

Don't confuse gear tuning with finding optimized shift points.

8500 may very well be the cars ideal shift point (for at least 1 shift) I haven't got that car, I would rather have it to calculate optimum shift points for each gear, usualy no 2 shifts are at the same rpm.

The Autozam has just 5 gears. It barely hits the limiter in 4th gear. The engine looses extremely much power after 7500RPM. I'm not sure but I think the car drives about 30km/h faster at ca. 8000RPM in the 5th gear than at the rev-limiter in 4th gear.

Its a 6 speed tuner ill put together one for 5 & 7speed gear boxes when I have a chance to adjust the calculations. That car seems like its not geared right at all.

However you made me think of a interesting test.

Gearing for peak power vs red line vs rev liniter.

Test can Easily be done with the calc, just change the "rev limiter" value to peak power then red line and adjust the fd until you hit max speed at the input rpm. Keep in mind the max speed indicated for each gear will be at that rpm.

I'm not home to test but it would be interesting.

 

[dr_slump]

Unfortunately, I also can't test it the next days.

 

[No_OBsT33R]

Unfortunately, I also can't test it the next days.

Anybody can if not I will later tonight when I get home.

That car seems geared all wrong my calc would have all that corrected.

The calc won't work on 5 or 7 speeds because the spacing is different over more or less gears.

It can be used to cancel out a 7th gear, I'm going to try this out on the C63 tonight also. Effectively using 6 out of 7 gears keeping 7th for a cruising gear.

Anybody use the calc yet?

They are if you use a bit of math to find your gear splits. (e.g. 1st x 0.85 = 2nd, x 0.85 = 3rd, etc though a 15% drop is pretty much impossibly tight for a 6-speed)

Something to note is that "equally" spaced ratios on the gear chart aren't equally spaced as far as RPM drop goes. If they have the same spacing on the chart there will be progressively less RPM drop for each gear.

That's not what I'm talking about.

First up he's on a 5spd not a 6

Next when you caulate shift points you are looking to match the power level in the exiting and entering gears. After you pass peak and power starts fallig you want to find that spot where your power doesn't fall past the power you will be at in the next gear at shift.

Ive successfully calculated shift points but it takes work and road test. I'm working on a calc for it.

Yup this is true and a reason why each shift point needs to be calculated and usually no 2 shifts are at the same rpm.

Or you can just set the gears to have the same RPM drop on each shift and find your shift point from there.

 

[No_OBsT33R]

Or you can just set the gears to have the same RPM drop on each shift and find your shift point from there.

That doesn't optimize the gears for speed/acceleration, it only equalizes your shift point at the cost of acceleration or speed in each gear except maybe 1.

 

[Rotary Junkie]

That doesn't optimize the gears for speed/acceleration, it only equalizes your shift point at the cost of acceleration or speed in each gear except maybe 1.

If you do it right it actually does. In fact, not doing so tends to sacrifice acceleration in a few gears.

 

[No_OBsT33R]

If you do it right it actually does. In fact, not doing so tends to sacrifice acceleration in a few gears.

I haven't seen this at all in fact I've tested and see the exact oposite. I've tested and can confirm the oposite. PLEASE show me a car and gearbox that shows otherwise (6spd for now).

What car(s) are you talking about?

Think of it like this, gears tuned to speed/acceleration using calculated shift points for each gear IS optimum gearing for speed/acceleration. If you alter a gear to obtain an equalized shift point the gear is being adjusted out of optimum position, raising it sacrafices speed, lowering it sacrafices acceleration. It don't matter that shifting at your equalized shift point is easier for you or the Driver, its slower then doing it right. While doing it right is harder.

The only issue is calculating optimum shift points is a pain with not much benifits. I've calculated them successfuly (the only one I know of to do so, so far) and while the benifits are noticeable, they are not much. Maybe a car with big enough drop could get more benifits from calculated shift points, it wouldn't be much though.

A test I made some time ago and I still don't know, whether it is that torque depends or not...

That's what I've written back then, in the "The definitive Gt5 transmission tuning guide" thread:

A short question about the Suzuki Cappuccino RM. I use it for the seasonal without a turbo, now would you agree that for this car it is best to drive all in the 5th gear because there is the best acceleration? I use the RKM tuning settings. Peak power is 65kW @ 7100 RPM and peak torque is 130Nm @ 4100 RPM and torque drops fast after 4100RPM. And if I add a turbo I would go for the low RPM turbo.

• No turbo: 65kW @ 7100 RPM and 130Nm @ 4100 RPM
• Low RPM turbo: 82kW @ 5300 RPM and 176Nm @ 4100 RPM
• Mid RPM turbo: 82kW @ 6000 RPM and 153Nm @ 4100 RPM
• High RPM turbo: 86kW @ 7100 RPM and 140Nm @ 4100 RPM

I tested this now with the Suzuki Cappuccino RM on Grand Valley Easy in the FR Challenge. Maybe you can use some of this information? It gives a nice overview, still there was some traffic on the road...

• No turbo:
  • Shifting at redline: 1:26,467 / 1:21,402 / 1:20,147 = 4:08,016
  • All in 5th gear: 1:21,816 / 1:18,038 / 1:16,879 = 3:56,733
• Low RPM turbo:
  • Shifting at redline: 1:24,352 / 1:20,075 / 1:18,956 = 4:03,383
  • All in 5th gear: 1:18,617 / 1:14,336 / 1:14,117 = 3:47,130
• Mid RPM turbo:
  • Shifting at redline: 1:26,022 / 1:19,029 / 1:16,867 = 4:01,918
  • All in 5th gear: 1:18,393 / 1:14,484 / 1:14,044 = 3:46,921
• High RPM turbo:
  • Shifting at redline: 1:20,545 / 1:14,797 / 1:15,323 = 3:50,665
  • All in 5th gear: 1:17,664 / 1:13,793 / 1:13,582 = 3:45,039

He thought that this is just useless, because I didn't equalize PP, but I still believe, that it shows that the torque curve has an impact on acceleration of (at least) some cars! Maybe you see some usefull info in it, not like grenadeshark and if not, well so what...

Ill definitly go over it when I'm road testing tonight. Its definitly useful, any info from road testing is useful, it won't tell the whole story but as I look over it I see ways I can use it, thanks.

Keep in mind it speaks to optimizing shift points not gear tuning.

 

[Basilea]

Well no problem! I'm always interested in programs helping to find gear ratios... no test can show the whole story! If you need help I offer me driving "skills" every now and then...

 

[No_OBsT33R]

If you could run the peak power vs red line vs rev limiter test as outlined it would definitly help to have a second driver doing the same test.

If its shown and conclusive that either is better than the limiter it's as simple as using that in the calc.

 

[Basilea]

Wouldn't this be better with exact the same car, settings and so? If no, could you explain it a bit better what you really need?

 

[No_OBsT33R]

Just to clarify, this is a gear tuner calc, your test speaks to calculating shift points.

Since we are testing gears, everything other than gears needs to be exactly the same...

For the test its been asked why the rev limiter is used in the calc as apposed to red line or peak power.

The test will compare how tuning to peak power or red line will hold up to tuning to rev limiter.

The larger the gap between rev limiter and peak power the better.

Well no problem! I'm always interested in programs helping to find gear ratios... no test can show the whole story! If you need help I offer me driving "skills" every now and then...

You in on running those test? Either way have you tried out the calc?

Has anybody? It's been downloaded a bunch already. No word back on it's results?

Did I make Gear Tuning too easy? Sorry about that

After a lil testing I'm finding that tuning for red line nets 1mph faster top speed with my test mule but takes a bit longer to get there. Tuning for peak power showed 2mph slower top speed with relatively the same acceleration as when tuned to red line, very negligible difference.

I'm going to test some more cars, feel free to test along with me. If you have any car equipped with a tunable 6 SPD you think we should test, let me know.

My calculations showed a slight fall off at red line, seems it's enough to gear to it, not past.

Like expected, the high rpm turbo wins. Why do you think that the torque curve has an impact on acceleration? The low rpm is the slowest, mid rpm turbo the 2nd.
It is not important how much torque the engine has, it's important how much power is delivered to the wheels. I mean the transmission output.
I remember that the Tuning Guide in the stickys has a great explanation.

That's not what's interesting about his test. What's interesting is that his faster laps are using ONLY 5th gear, no shifting....

Do_OH! lol...

How does this guy get Dogged when he's actually done a test providing very interesting results? Wait, GTP, never mind.

Ok, I see!
The question is: How long is the 5. gear?
Is it right that the Cappucino has a horrible torque/power curve? Cause you shifted at the redline which is sometimes terrible (remember the Mazda Autozam...).

Do_OH! lol...

Relax, holly crap this board lives on Edge. The kids been getting his test slammed a bit. Not "attacked" I said "dogged" as in his test is not getting the respect it deserves...

I find the info it provides intriguing. Maybe it's just me.

 

[dr_slump]

Another question is how fast were you driving Basilea?
I'm interested to know the range of speed you've driven. I think it could be possible that the cappucino is so slow, that a big part of the track was driven with almost the same speed. Possible?
