So very shocked and saddened about the passing of Mike "Daz" Dillenger. What an incredible person, unselfish to a fault. Tremendous loss for VW/Audi tuning community.
So among the my first conversations with Daz many years ago was a PM where he explained some kinks in a PES tune he did for a C5 S6. I was inquiring about a project seed, a plan to rebuild and modify a second PES Stage 2 setup for the BHF 4.2L.
"Keith, he also has a PES kit. As for the kinks, there are ASM hacks required to get rlsol_w over 100, fkkvs hacks, and a ton of fueling changes. Massive timing scaling, etc. It is a very difficult process. The 2007 is an ST processor. That's going to be next to impossible."
Later he signed on to do the tune on the PES-based MP112 powered setup for my BHF S4 V8. We were discussing using 550cc injectors at 80% duty cycle and we were trading emails and messages for a while, working to assemble the bits and kit I needed to get installation started. And today in retrospect, after spending a day in my workshop swapping rotor packs honoring him in my own way by again setting about the tasks he and I plotted to move forward, I remembered this early message.
What does he mean about the ST processor being an impossibility? He eventually changed his tune (pardon the pun) and related he was going to have to literally build the definitions by hand for the logger, a process he loosely described as akin to sucking balls.
So what's the ST hangup? Why is BHF 2007 edition more of a PITA to remap than the earlier 4.2L versions? It's been a while since I have posted here, but I thought in Daz's memory, I might try to make a more regular appearances and actually try to engineer some of this solution myself.
RIP Daz. You were the walrus. Koo-koo-ka-choo.
