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.

why did you sell the car? And what did you replace it with?

Hey guys,

We have been working on some new features on 992 this week on the dyno. We are excited for future map updates that will soon be available that have some really good power improvements and new things to tinker with. Here are some pics on the dyno this week on our 992 C4S, we added an EMAP sensor to the passenger header bank near the collector. This sensor measures exhaust manifold pressure. As we make calibration changes as well as hardparts changes, we can monitor this pressure and see how it improves turbo efficiency therefore maximizing power. We are able to monitor this EMAP data on an aftermarket datalogger separate from the ECU, as this sensor is not a factory Porsche sensor that is used on the stock ECU.

We also have updated logging profiles which contain a bunch more monitors which makes for more seamless data analyzation and improvements when ProTuning using M-Tuner. More nerdy stuff to come soon!

Nice. It'd be nice to see if any of the aftermarket header options actually make more power (or give you the ability to do so). QQ -- whats the limit on the stock MAP sensors? 3Bar?

M Engineering

We have yet to see any header option make power on this platform or the Turbo. They all lose power, and not just a little bit. We will certainly let the community know if we find a nice system that does work well.

Our post above is different from a MAP sensor. A MAP sensor measures the manifold pressure on the intake side. The stock sensor is 3BAR if memory serves me right, I'll correct this post if I'm wrong. We haven't had a car max out the sensor on a Carrera before. On the Turbo, we have an upgraded 4BAR sensor when doing bigger turbos like our PTME1100 as we quickly go past the factory MAP sensor ceiling.

What we are testing is EMAP, so the exhaust side instead. The exhaust side goes quite a bit higher.

Thanks Charles -- yup, I'm understanding on MAP vs EMAP, I was just wondering how much headroom the GTS turbos had on the boost side before MAP sensors needed upgrading. Im guessing they just generate heat above 2bar absolute anyway, hence the Pure700 option but figured id ask. But as far as EMAP then, if no headers have added power yet, this is mostly for Stage2+ tuning optimizations based on what you learn from peak EMAP levels on stock plus hi flow link pipes? Hard parts has my interest piqued as well

Keep up the good work, can't wait to see what you guys do! Time to nerd out for sure!

M Engineering

The EMAP testing is important, and we plan on reviewing data with it based on all hardparts installs including exhaust variants, different turbos, even stuff on the intake side. All of our calibration decisions are made based on real data, rather than just strictly trial and error. We prefer a more empirical approach to making changes and testing.

Thanks Charles.

So these new updates will be available to flash for us that already have custom tuned/datalogged maps (from mods like aftermarket exhausts, cats, turbo inlets, etc)? Would we flash to the new update and then need to eventually do the datalog process again to fine tune based on our specific mods? Just curious since I’m on rev15 stg2 lol

M Engineering

No additional information at this time on new maps, we are still working on them along with our features.

Charles, just to clarify, those new features and maps are also coming out for cars with stock hardware or are they targeting cars with upgraded turbos, exhaust, etc. only?

For those running Stage 1 (or 2) on a Carrera S/GTS, how many of you are changing the gapping on the spark plugs? How necessary is this for Stage 1?

reddsektor

I ran stock plugs for a while on stg2 but then had the dealer re-gap the new plugs (during major service interval) to 0.022 last year.

Couldn’t tell much of a difference but did it anyway. I believe it’s not really necessary for stg1.

Master Deep

I was curious if a dealer would do this. Good to know. I’ll ask at my next service.

@M Engineering

Apologies if this is addressed elsewhere, but what changes do you make to throttle response in the various drive modes? I drive the car in Sport 99% of the time and find the throttle response pretty ideal for spirited street driving. If I were to tune, I wouldn't want to modify that behavior. Is this something that can be 'left alone' or ??
