I'm practicing reverse engineering because I have A LOT of requests for this on Porsche and other platforms, and 991.2 use the same processor so not very different even being a continental ECU.
I'ts going great, I figured a lot of stuff out, and it feels good not to hit a dead end when you cant fix something using what the oem software can do.
Apart from all the usual multimap, rolling antilag and all, I want to figure out how to control port injection with the stock ECU.
Doing the math and splitting the fuel mass between Di and MPI is easy, just need to figure out how to use a free memory location to put injection ms there, then send it to the can tranceiver, then picking it up on the can bus later.
easier said than done but 300% doable.

Rolling antilag is cool stuff. Be kind to your cats though (if you run one).

Still following your thread with a lot of interest, you have so much depth of knowledge and fun to see you playing with the electronic systems with deft.
I have been driving the car stock and have been getting a bit bored. Engine for me is "fine" but wish the chassis was more playful. Would be fun to have an e-brake to slide it around and back it into corners.
If you were thinking about adding on an e-brake do you think it would be possible to modify electronic systems to use the e-brake already present as an electronic "hydro"?

that never crossed my mind lol.
btw, testing flatshift last night and setting some base 100-200kph times on a friend´s car
this tune is our base for trackdays, will probably push 30psi on a street tune to see if it can get to mid to high 7´s
Also maybe 100rpm more and we could do it with 1 shift only

Something cool, finally.
Will start working into a full Reflex+ integration this week.
This means port injection how it should be. Everything controlled and calculated by the ecu. The Reflex+ will only work as a CAN driven injector driver with 2 way communication. That means I can even trigger DTC´s if the MPI injectors fail etc.

Sorry if I missed it... what are you using for hardware for the PI?

Reflex+ is a port injection controller that connects via CAN network.
It can work in many ways, but for my use, it will be used as a I/O expander for the oem ecu.
I have added all the necessary tables on the oem code, so it calculates injection time for both mpi and DI based on a split table I made and broadcast the value in the can network. The controller picks up the variable via can and pulses the injectors accordingly. It is connected to the CKP and CAM sensors to sync and works fully sequential.

Question: Can autotuner jailbreak FL5? I want to use hondata, but I can't use hondata jailbreaking here

In regards to the main topic:
Progress is not as fast as it was before, but always moving forward. I have implemented flex fuel in my patch, using ECT2 as analog input as Hondata did on the fk8.
I never had time to integrate the reflex+ via can, but I ended up makin my own board to control a couple of things, and also adding a LPFP pressure sensor to the ecu to add safety in case pressure drops.
On the other hand, lots of developments for the Porsceh crew, been working really hard to launch our new product at PRI in december. if any of you is going to the show, let me know. I will have some merch for you as a gift.
