    • B&C Consulting cracks the 9A2 SDI21 ECU with tuning available for Porsche 991.2 Carrera, S, GTS, and T - Tuned GTS dyno result

      It is often amusing to see after a crack for an ECU is announced it then spreads out like wildfire. B&C Consulting offers tuning for the 2017 on Porsche 911 (991.2) 9A2B6 3.0 models now having access to the SDI21 ECU much like Autotuner.


      Whereas Autotuner sells the master system to tune these ECU's to tuners B&C offers tunes and dyno'd the cars.

      No, this is not an OBD-II tune:

      This is a bench flash and the ECU must be removed. It is not too terrible of a process and PorscheBoost.com will put up a DIY on removing the ECU later this week:


      The dynos are where things get interesting. Unfortunately, they are crank corrected:



      The crank rating for the 991.2 models is underrated so keep that in mind when viewing the graphs.

      What we learn is that the GTS is easily clearing 500 horsepower with a Stage I tune. We would expect it to be a 500+ whp car on a Dynojet with bolt ons on pump gas.

      The Carrera shows much larger gains from stock to tuned. That is because it is not pushed nearly as hard with only 13.1 psi of boost stock. The GTS is in a higher state of tune and its turbos are definitely being pushed more off the showroom floor.

      A 991.2 Carrera with a tune should have no trouble dispatching a stock 991.2 GTS. It likely will nip at a 997.1 Turbo's heels. If one were to guess, it should trap roughly 124 miles per hour and be on the verge of that 10 second barrier. A bargain in the Porsche 911 world, definitely.

      As these tunes get out there and more people dyno we will have a better idea. This is just the beginning but 991.2 3.0 models are about to become very stout, very quickly.

        Well, still bench tune but should help GIAC see the light

        I saw in either rennline or 6speed a combo with Akrapovic exhaust and ECU tune, couldn't tell the vendor of the latter

        If interested contact Craig there to see if it was an error. I have used their dyno (the only variable speed wind tunnel in the U.S.) and installed some of their 991 Turbo goodies (on a friends car)

        He seems to basically be begging for a car on the forums.

        No results or anything to show.

        Gintani is going to do my car.

        Quite a few instagram photos of the stage II setup. Perhaps this option should be broken off into it's own thread?

        https://www.instagram.com/br_performance/

        Advertised output for stage II is 472HP. Looks like calibration, full Akro exhaust, BMC Air Filter

        Not to derail the 911 discussion but really keen to see more on the Cayman S gains. 911S power with just a tune? Sign me up!

        Right there with you. My wife wants a Cayman GTS as a fun toy.

        Your wife has good taste :-). Mid engined and roughly 200 lbs less than the 911. Will make for an amazing performance package if we get it to 911S power levels.

        I'm pretty sure the Stage III will be utilizing the GTS turbos, especially since their advertised numbers for it mirror the stage II numbers for the GTS.

        It will be interesting to see how well programming and other high flow catalysts will work together, since we are seeing these results with the Akro system.
