992 Carrera OBD Flashing
#1366
2020 C2S, been tuned since 7k miles now at 17k. The 93 octane tune has been pretty good, but there are occasional issues that are more of a nuisance than anything serious - PASM errors, certain features disabled. Overall, happy with the 93 map and I’m sure Mitch and the team would take care of the above I’d I reached out.
Unfortunately, I cannot say the same for the e85 map. Have had issues from the get to as have a few others in the board. Seemed like a rushed beta tune versus a final product. The team has been quick to respond, but after a few attempts I’m done with the e85 tune - not letting my car be the guinea pig.

Thanks Mitch. While my car was a challenge to get right, I don't think many other vendors would or could offer the level of service that you guys have provided. Always responsive with a goal to get it where it needed to be. Glad at least for now, I don't have to worry about replacing the injectors.

I’m told it was the ROM version on my car, they’ve been able to get it to hit intended boost/torque targets. @M Engineering can comment further if they like. Car continues to run good. Sending another datalog over after a timing adjustment.

Guarntee they will tell you what adjustments they are making to the tune, just ask.
I'm not certain how many end users understand the complexities that go into a tune for a turbo charged/ non turbo, fuel injected, EPA/ EU compliant vehicle.

@991.1 Guy we get it, you're unhappy. Please discontinue bringing it up again and again and again. Thanks.

I want to switch gears a bit here and show you guys some more of the development side of what we do here.
We are testing with our in house 992 Carrera 4S. This is our test mule for testing parts, and tuning so we can see what the cars are actually doing when increasing power out.
I attached a few pictures of one of the EMAP canisters for the Carrera. We will start with one for each turbo and measure what EMAP is stock, and then turn power up. Once we do that we will then switch the exhaust out with a bigger unit and run the same tests. We did this same thing in the 992 Turbo S so that we knew how much boost pressure we were achieving especially when running 35psi(g) of boost pressure. We plotted that with a bunch of combinations of exhausts as well as one set of headers. The data is pretty eye opening from those tests, but these ones we will make more public, since I feel like you guys want to see some more technical data.
For those curious, the EMAP sensors measure exhaust pressure from the engine and turbos. Think of boost pressure but instead of inlet manifold pressure, this measures the backpressure that increased power is outputting in Psi (or whatever unit you desire) It is using AEM 10 bar pressure transducers with T1 Race EMAP mufflers. The mufflers are used as a filter, so that the exhaust pulses don't throw the readings off, and gives us a much cleaner pressure channel. This is a quick log I grabbed from doing some intercooler testing in house so we could validate data and just simply measure what the stock and aftermarket intercoolers looked like when compared to each other. We have much better data plots but I figured I would throw this one up.
And this is what one of the EMAP setups looks like before it goes onto the car:
Stay tuned as we get some more data from this. This test we will run more sensors on the car and use a Motec C127 dash as well as our custom logging to tie it all together. Should be fun!

Now the other reason for all of this a few things. It is showing us empirical data of how well parts work. Things like exhausts, headers, intercoolers, etc. We don't make these things, so sometimes we do it for 3rd party companies which many of you use on your cars today, to give a real engineering analysis of things like pressure drop, intercooler efficiency, exhaust efficiency, header efficiency etc. The other we learn is what doesn't work, and we relay that to customers as best as we can. We don't make money on hard parts for the most part, we simply want to make sure customers know the best parts to use, and which ones not too use. We do this not to throw anyone under the bus, but a lot of the time we will reach out to companies and share with them the data so they can better there product.
Long story short we do this so we know that we are making calibrations that are quality, not pushing a car to its edge. We know how much each and every Porsche means to everyone we work with, as we all live and breath this. So we simply want empirical data that tells us exactly what we want to know, so that we can better our products, and maybe others along the way. Hence the shirts and hats we made that said "In god we trust, all others bring data." We are a very data driven company, so we outfit cars like this so we know that what we are doing is working, plain and simple.
I hope that helps. If you want a more math sided answer I can do that too.
Cheers,
Mitch McKee

I just found out I have Mechanical Breakdown Insurance from Geico that will cover any mechanical breakdown if manufacturer doesn't pick up the bill. This means I can run a tune and if the engine explodes then I pay $250 for a replacement.
Looking to try out this tune after tax season.
