Redshift Performance Intro - Taycan ECU Performance Packages

Claiming 800+ bhp without dyno evidence doesn't build consumer confidence

I understand where you’re coming from, but it’s a pretty straightforward calculation. I don’t know exactly what the programming/modifications look like, but I have to imagine that somewhere, either in tables or low level programming, they’re modifying the current limit (or possibly multiple current limits set for different scenarios). That will directly and proportionally affect torque, which will in turn directly and proportionally affect power. So, assuming the changes are effective in that they do what they intend to (which I have no reason to believe they don’t), it seems safe to claim the power increases even without a dyno, IMO based on working in industrial electric motor control for almost 20 years.

I’m sure you’re right but physical measurement beats theoretical in my book. I received a nice dyno graph with my stage 4.25 GT-R tune which I still cherish

I have a 2021 Taycan Cross Turismo Turbo S and connected with Mario at RedShift to pick up a modded ASG/ECU. I opted for the backup ECU just in case I need to bring the car into the dealer. By next weekend, I anticipate having the modded ASG installed. I'll provide everyone here with the details including seat of the pants differences and Draggy runs once everything's is set up.

Additionally, I own a 992 Turbo S equipped with a flash, catless downpipes, and BMC filter, running on 93 octane which runs 9s on street tires. I plan to conduct side-by-side comparison runs (992 turbo s modded vs taycan turbo s modded and stock) with before and after videos for reference.


I've already gathered some baseline figures on both cars and will continue to collect some more runs from the Taycan before the mod is installed.

I'll be logging before and after runs at different states of charge (SOCs) for metrics like 0-60 mph, 0-100 mph, 60-130 mph, quarter-mile times with trap speeds, and top speeds. I'll also include metrics like 100-150 mph, 100-200 kph, and 0-100 kph.

You are a star...can't wait to get to read that write-up. Thank you in advance. Enjoy the testing.
Also driving a CT TS so this is of particular interest. Got used to the TS power again so a bit more power won't harm. Cheers

Sorry, just trying to clarify: you received a dyno graph of a car with the tune, or of your car after the mod? 'cause I'm sure you can get anything you want if you're willing to pay for it ? .

My car after the stage 4.25 tune. I was present when the dyno runs were undertaken too …

Thanks @keithta

It’s a shame Redshift don’t provide simple before and after dyno charts for their tune. I’d be all over it with such compelling proof. Claiming 800+ bhp without dyno evidence doesn't build consumer confidence

Very much looking forward to your butt dyno results?

Dyno would be great, but I'll consider the promised Dragy runs to be objective evidence of any improvement.

^^I cannot wait. I will be doing the exact same thing soon! But I have a TS sedan

That's impressive.

The point I was trying to make, perhaps too subtly, was that you requested dyno printouts of other's tunes, and justified the request by saying that you obtained one for your car. As you probably noticed, there is significant concern around the impact on warranty of this mod, so no one is really in a hurry to publish their results (hopefully it's evident why). Further, as @Jhenson29 explained earlier, mods on electric motors are far less mystical than those of ICE engines; in this case, the cx can choose how much they want, and RS Perf will code those values appropriately. A dyno pull would simply prove that something has changed (ie the mod has an effect), and nothing more. (Well, okay, perhaps it also proves that the calculation current->power was is correct.)

 

[n3ophyte]

I think we both misunderstood each other. I was simply suggesting Redshift or their German counterparts could publish actual power and torque figures for their tunes the way ICE tuners do here in the UK. I‘m not suggesting individuals should disclose their results due to the warranty concerns you raise.

The tuner I use publishes detailed power and torque graphs for each level of tune they offer here …

There is something with the 2 speed transmission that makes it very difficult to Dyno.
That's the issue

Ah good point! I hadn’t thought of that

I have zero interest in this, I rarely get the opportunity to use full power in my CT4S anyway and the main attraction of the Taycan for me is how it drives, not how it accelerates. The chassis mods were worth it for me (torque vectoring 4WS, active ARBs) more power wouldn't be.

Anyway I did my engineering apprenticeship with a specialist gear manufacturer then worked for them 4 years post University and one thing that is easily shown is damage to transmission related to time at high power. Most likely gear surface pitting leading to failure.
The fact that the gears and associated parts are strong enough to take an occasional launch does BY NO MEANS mean using that power level frequently will be fine.

Porsche would have no trouble rejecting any warranty claim on running gear of a modified Taycan, any expert witness would confirm it.
Whether it actually was because of the mod or not is moot.

Interesting. However, if I was to tune my Taycan to the advertised LC power, doesn't Porsche advertise unlimited LC usage, so even if I used LC at every single stop, it should not void the warranty? Also, using max power from a complete stop exerts higher forces on the transmission given electric motors produce their highest torque at 0 rpm, so perhaps using LC power at highway speeds actually causes less transmission wear than drag racing.

It is irrelevant if warranty is the concern.

More power used than provided as standard by Porsche undoubtedly creates more stress on the transmission and could be used as an incontrovertible reason not to warrant the transmission, that is all.

Gear wear and pitting (which is local compression failure of the tooth material) are related to time, load and speed so a simplistic view is irrelevant to any real world technical evaluation.

Everything may be OK but it is the owner’s risk and nowt to do with Porsche IMO.

But Launch Control mode is provided by Porsche as standard feature of the Taycan, no restrictions on activating it every single stop. So if I simply activated LC at every opportunity, would that be covered by a warranty?
