Yes, I recall references to 2.5 sec, but that would be odd for the non-turbo models as it means you don’t even get the full benefit of overboost for a 0-60 run….and the turbo models would only get the benefit of it for 1/4 of the quarter mile.

This would also make my “tuned” quarter mile time very odd given the stock Turbo is quoted at 10.9 sec @ 127mph ….effectively implying my car is making less HP than the Turbo in overboost (seeing as the “overboost” is permanently enabled in my car). I would add that my GTS feels significantly faster than before so I do not believe I am *only* making Turbo-level hp figures (615 or 670….relative to stock non-overboost GTS of ~510).

Overboost permanently enabled does not mean it will be continuously available for however long you choose. Just like LC, there will be a limit, but rather than time defined, it will be based on motor/inverter/battery heating and other parameters. Porsche detuned Taycans for repeatable performance. Tesla lets you tap maximum performance but throttles the use to prevent motor/inverter/battery damage. As far as I can tell, this upgrade unlocks the full potential of the hardware your Taycan has, but will throttle it to preserve the components, rather than to preserve repeatable performance and enforce trim performance limits.

PS> Could you log power produced during your runs via CarScanner or other similar tool?

the negative to that immediate power delivery might be faster wear level on parts. the regular Taycan power delivery is just fine, having the ECU reprogrammed to deliver full amount and not partial is all that was needed IMHO.

This is what I am thinking too, even my "dumbed-down" RS e-tron is sufficient in how it responds in day-to-day, it's light years better than any ICE in responsiveness as is.

Correct me if I am wrong but launch control does not affect 60-130 times. You only have it for initial (I think) 2.5 seconds 60-130 is unaffected From LC.

If torque/nM doesn't change in overboost, it's actually not the initial 2.5 seconds, but rather later in the power curve to extend that torque/nM line an additional 2.5 seconds to reach the overboost HP rating. To answer your question though, correct, overboost function on the OE car does not impact 60-130mph time.

If that is the case, then in 1st gear, overboost does not occur until approx 30-35mph (depending on model/trim) to hold that torque/nM line.

Were you in the (German-language only) developer mode? BTW that's where my German-fluent mechanic found the setting to disable the trunk close beeper.

any chance you can find out from him what the coding for that is called? i've dug around but its miserable to do with a translator

answered my own question, i was making it harder than it needed to be

Just posting my performance results after installing a secondary ECU with the REDSHIFT Stage 3 tune.

Car: 2020 Taycan Turbo S
Mileage: 11,764
Battery SOC: 70%
Ambient Temperature: 14 degree C
REDSHIFT Stage 3 options: 800+ bhp, no speed limiter, unfiltered throttle, increased regen power

Driving impressions: Car pulls hard and instantaneously with launch mode ferocity from all speeds - thank God for the head restraints! Increased regen is very noticeable. Previously I could coast to a stop at junctions and lights but now I stop short unless foot remains on throttle. Definite increase in ‘engine braking’. Snappy throttle response at all speeds and drive modes but easy to drive smoothly. Nose lifts under extreme acceleration. Don’t recall this previously.

Here are my before and after numbers …

I don’t think this is right. AutotopNL tested this for RWD and proved 100-200kmh materially improves in LC mode. 2.5 sec limit is a time limit during when max HP is available (eg during the rev range when max HP is delivered, which should be >50 mph to begin with), it does not the define the entire time period during which LC brings extra oomph. And even within max HP rev range, there has to be some smoothing after the 2.5 sec period. Take RWD for example after 2.5sec of delivering max 476hp i can’t imagine the torque being suddenly cut 20% and going back to 380hp instantly. Maybe there is another 1 sec of 440hp and 1 sec of 400 hp and so on. All the data sheet indicates is 476 hp is available for 2.5 seconds, does not tell you what happens in the next second and so on.

Stock ASG, Launch Control does affect 60-130. You only get full power with launch control. Without it, you get reduced power (750 vs 616 on turbo S for example)

I concur with this!!
In my testing, launch control was significantly faster, more than a second, from 60-130mph than just flooring it. I was in the 9 second range sometimes without launch control, usually in the high 8s.
With launch control I went as fast as mid 7s 60-130

Would be interesting to see what the turbo does compared to the S with the different front inverter

would the increased recuperation improve efficiency since you are putting more energy back?

 

[n3ophyte]

I don’t think so. Increased recuperation force just means you slow down quicker over a shorter distance. Normal recuperation achieves the same result but over a longer distance. I.e.

total_recuperation_energy(kWh) = recuperation_force(kW) x time​

I prefer to coast as it’s more efficient than recuperation anyway. However, when you do have to brake it’s nice to generate useable energy rather than waste it in heat and brake dust

You have a point.

If the TQ/nM line stays put to reach the overboost HP figures, on the RS e-tron GT would be closer to 75mph (+/- approx 3mph) before things dialed back down, so yes, that would impact 60-130mph times.

side note, VW Group really locked down modules with the updated SFD2 protocols on my 02/2024 build car, I can't access any modules to read the ECU to send to Redshift unfortunately until Ross-Tech can get this unlocked, so I won't get the experience the joys of this software until later unfortunately.

*update* you can read out for MY2024 using the beta Ross-Tech by setting the cable to BETA mode.

+ 15-20%.
So RWD (with PB+) would go from 380hp without launch control to 476hp (launch control hp) +15% = 550hp (available AWAYS).
so, a 44% increase at available power when driving without using launch control.
I can’t wait to try!

Did you had the chance to try it ?

 

[frietzak]

@redshift-performance do you already have RWD 0-60 numbers?

 

[Lefty8235]

Quick update on the major improvement I’ve seen since the upgrade. I have a ‘24 Turbo S so I already had the benefit of the SW upgrade that gave over boost a 10 second sprint.

I wrote a full review in a different post but 3 quick bullets:

• no major change to launch numbers or 1/4
• The throttle response at highway speed is dramatically improved
• My 60-130 from a roll was 6.92. I haven’t seen anything close to that and I believe others have reported pre-tune numbers much higher. I didn’t get a pre tune myself. This was done in first gear from about 45mph

 

[ntom32]

As a Taycan RWD MY22 PB+ owner I installed the new ECU (20% more power available all the time, speed limit removal, unfiltered throttle response). At 60% battery, which is a realistic scenario (I never charge to 100% anyway), 19ºC outside temperature, 28ºC battery temperature and Michelin PS4 (not PS4S) 20” 245/285 tires, this is now a car it should have been from the factory. Acceleration is such that on a slick and dry asphalt even at 60km/h traction control steps in. My relationship with my RWD PB+ was love/hate until now, a great car but underpowered. Now it is just perfect and I have no desire to own a higher trim.
