Anyone tried the Speed buster piggyback?

Seems like pretty good gains for a piggy back with no chance of being detected by the dealer. Any experience? Draggy at 1 min mark.

Again, there is no such thing as a tune undetectable by a dealer. It will be discovered and it is much better to be honest about it.

Companies love to market these devices as “undetectable” for warranty purposes, but it’s simply not true.
Even the use of an alternate cloned ECU can be detected, because there are other counters in the car that won’t match up like the number of engine starts.

Piggyback solutions work by altering sensor values to get to the desired characteristics of the tune. When the piggyback is removed, someone examining the ECU will notice unusual min/max values and history that doesn’t make a lot of sense. The operation of the piggyback leaves tell tale signs that are still there even when it is removed.

It blows me away how many people just dont understand the piggyback/tune game.

From someone who works in the industry for a manufacturer.
Pretty much all cars have GPS and know their speeds and accelerations in all 3 axis. There is no way that any OEM that wants to set limit flags based on the maximum accelerations seen during development won’t know that a car is performing beyond what it is capable as produced if they want to look. There is no easy way to avoid this type of detection.

sorry but no way. Your warranty is denied and vehicle flagged when a different version of software is flashed or when it detects a flash counter change. There is no way in hell they can prove anything using gps or any conceived limits. It just won’t stand up and they never bother to go that far even if they “can”. It has to be hard proof not hypothetical limit exceed for an unknown reason. I’ve never heard of any Mfg declining claims based on these so called reasons. Show me one example from any Mfg where piggyback which was removed resulted in warranty being denied. There are plenty of examples of warranty being denied due to a flash.

If you seriously want to do a tune, here is a ranking of tuning approaches...
Notes
- ECU running a custom professional pro tune, done on a dyno with your own car, that can be installed or updated via the OBD port (Not currently available for a 992)
- ECU running a custom professional pro tune, done on a dyno with your own car
- ECU running a custom bench tune, done specifically for your cars modifications
- ECU running an OTS (off-the-shelf) tune that can be installed or updated via the OBD port (Not currently available for a 992)
- Cloned ECU running an OTS (off-the-shelf) tune
- ECU running an OTS (off-the-shelf) tune
- All piggyback tunes
Notes
- Personally, I put piggyback setups even below that, but I didn't want to waste so much white space in the post. Piggyback tunes are limited by the sensor ranges that can be falsified and can't deliver the reliable gains of the other approaches. No one should be doing a piggyback in 2021. If you're going to do the job, do it right.
- I could have added "Cloned ECU" for each of the top 4, but it doesn't get you that much from a functional standpoint. Any of those top 4 would work with a cloned ECU as well. The Cloned ECU does earn a spot for an OTS tune, because people doing an OTS tune tend to like a quick way to get back to stock, ie. budget oriented.
- As of this writing there wasn't a plug-n-play solution like the COBB Accessport for the 992, there are some firms that can support OBD updates once the communications stack on the ECU has been modified or unlocked. I don't know of a big name offering this yet. If you know one, feel free to chime in.
- One of the unsung benefits of a protune or local bench tuner is that you can tune for the gas available in your area. Octane is just a starting point, because ethanol content and other local variations can have an impact when you're starting to push the boundaries. If you plan on rallying or long road trips, be sure to have a 91 octane tune that you can use, ideally switch via the OBD port, because 93 isn't available in some places.

Driving like that on those streets, beyond imbecile. Did anyone else notice the (street?) lights reflecting in the instruments on the run around 1 minute? The one that got to 284km/h (176 mph).
