Redshift Performance - News & Updates - Secondary ECU in the mail without shipping original!

[simcity]

No. Haven’t bought a Dragy yet. If my butt dyno can’t detect a performance boost I may buy one. Shouldn’t be necessary though.

I also optioned

1. Unfiltered throttle response
2. Removal of the 160 max mph restriction
3. Increased recuperation force (engine braking)

To be honest, I already get tunnel vision when doing the standard tune 751bhp launch for 2.5 seconds. Having 800+ bhp on tap at all times will be mental!

Sorry might be covered already. What’s the cost for the options you mentioned?

I always assumed driving mode changes throttle mapping, i.e. Sport+ makes the throttle more responsive. I'll have to pay attention next time I drive, but I do remember long time ago, on my very first Taycan test drive, when I put it in Sport+ my impression was that the car became very "twitchy", even small accelerator inputs would shift down. Switching to Normal made the car seem calmer. That said, this was my very first Taycan impression, I might have just been noticing the gear shift mapping changing rather than accelerator mapping.

It does (change with mode), I meant to say that for a given mode it doesn't seem to change over time/with driving. Also, for my 4CT, there's only so much difference that the mode can make with a mere (3)50hp at its disposal, applied to a 5 tonne truck.

No extra cost for the options mentioned. They’re included in the price of the tune whether you want them or not.

You could justify this tune in the following way. A new £161,000 facelift Taycan Turbo S has 764 bhp available in normal driving. My old Turbo S will have 800+ bhp available in normal driving and it will only have cost me £3,482.

Man maths is a powerful thing!

What difference have you noticed on the increased recuperation?

What difference have you noticed on the increased recuperation?

I haven’t fitted the Redshift Performance ECU yet. Will do that later today (Wednesday 19th).

I’ll do some 0-100-0 mph runs with CarScanner before and after fitting the new ECU. I’ll also do 1/4 mile runs if the terminal speed isn’t too crazy. Will use throttle off braking only (no brake pedal) to log difference in regen power.

Okay…ran down to Mexico to do a quick test using the CarScanner app. Battery was at 65% SOC; did not use launch control (wasn’t sure it was necessary but may still enable better launches) and was not on an ideal surface. Unfortunately, I didnt have the ability to get a 60-130 time.

Based on data I found at AccelerationTimes.com, here are the results for a stock GTS / Turbo S:

0-60mph: 3.4 (really? I thought it was more like 3.8)/ 2.6
0-80mph: 5.8 / 4.7
0-100mph: 8.9 / 7.3

So even without launch control or close-to-full battery, a significant improvement over stock GTS (-3.1 seconds 0-100!) and 0.5 seconds better than Turbo S, despite a much worse 0-60.

To extrapolate your data, I would expect a half a second improvement if you started out with a Turbo S

 

[EXOTIC3]

Tried calling their office for some info.
The turbo for $3500 tune doesn’t really get much of a boost with the tune?
Only GtS & base ??

 

[unbiased]

Go to their website and it will show the which version gets what boost.

Waiting ever so patiently for RWD PB+ stats... If I wasn't on business over seas for the next 4 months I'd be the sacrificial lamb.

 

[paulbroere]

I’m getting the tune for my RWD with PB+
It may take a while since I’m ordering a secundaire ecu, and I first need to read out data from my Car.
My collegae had a dragy. So I Will get performance data before and after! (I probably won’t do a dyno-run, since it seems very difficult for EV’s, especially with the two speed transmission

 

[ElectricV8Biturbo]

Draggy/Racechip/Dragstrip/Airport runs with timing equipment/ etc etc are all you need with EVs for the near future.

Anyone asking for dyno or actual horsepower measurements on an EV today is not wanting to modify and that is your prerogative. But it's just clogging these threads unnecessarily.

EVs in general do not Dyno well period. Even teslas with their single speed trans will not Dyno without risk of breaking something (car or Dyno). I am sure anyone who takes the time to look into what they are asking for will easily find this info on the.web somewhere with countless videos etc of failed attempts.
Part of the problem is the instant torque EVs put out, others is a whole host of sensors EVs rely on to drive being glitched by standing still yet spinning the tires (much more advance traction control capabilities vs ICE which is mostly reactive). Add on a two speed transmission and it gets worse.
We won't be seeing actual reliable dynos on EVs for some time to come period!


All that aside, I have been modifying and dyno'ing cars since the late 90s when I was a wee lil lad.T
Dynos were and have always been a tool not a measurement of a vehicle's performance. Tool as in use to see if a modification made any changes to the car's output.
But I have also had cars Dyno tuned with mods that made much more power on the Dyno and the car went the same or slower at the Dragstrip. And I have had countless mods that made zero power (sometimes even less power than what I started with) and the car was significantly faster on the dragstrip.
PS: I am ignoring all my previous dynos that I felt were manipulated by the operator to show more power in the above comparisons.
Cars just don't.behave the same way on the Dyno as they do when driven. My experiences have made me only use the dyno to create a base map and use track or street tuning (with data logs) to actually finalize the map. Most times, track or street tuning results in lower Dyno numbers than a Dyno tune, but a much faster and more consistently faster car!

PS if the above doesn't apply to you, don't feel the need to respond.
Let's carry on and see what folks are seeing with the draggy/dragstrip/Racebox info

 

[Hegi]

I got answer for my question via mail from them. RWD should get 20 percent more power then it has in LC permanently. That would be 490 HP instead of 325 without PB+.

That's about what other dual motor electric cars have. So iam wondering how durable that will be with one motor?

 

[Lefty8235]

Considering you're goin from 616 HP to 800+ at highway speeds, it seems like this is all the benefit you need.

To be honest, I've launched the car like 3x. It was cool, but when is that practical? I pop out and step on it on the highway all the time, however, so that seems worth if if that's the pickup.

From what I have read, the biggest differences in the Turbo and Turbo S with the tune is having access to all 800BHP at all times and not just during launch control mode. Outside of that, there will not be much of a performance change with 50bhp on a 5200lb car!!! maybe a 3mph increase in trap speeds in the quarter mile (130/131 stock vs 133/134mph tuned).
The 60-130 will be the biggest change since that can be achieved from a roll instead of only with launching from stop (with launch control active)

 

[Avantgarde]

I am not sure an actual dyno test is needed here. Tuners should be able to tell, based on their reprogramming, how much additional current they are sending to the motor at any given RPM. The rest should be a mathematical exercise to get to torque and max HP. My big question would be how much the max torque is increasing (even a 10% bump in torque will make a difference, helping the low speed kick, which the RWD lacks). From a max power perspective switching to constant LC power alone (even if it does not come with more power) should make a big difference at speed, given the kick downs around 50-70 mph would give you access to 476hp vs 380.
