Thanks for sharing....certainly will consider for my RS.
I've been impressed all around with a Cobb Accessport on my Raptor.

Larry Cable

yeah I had their ECU and PDK tune on my 991.1 GTS ... unfortunately its not yet available in Ca! (C.A.R.B certification)

Really impressive that they could get 500 whp from the .2 with a tune and race gas.

The .1 still makes ~435 whp with just a tune, but the biggest gains in midrange are the most felt. Curious if a set of headers would take the .1 over the 450 whp mark.

Larry Cable

I'll probably pick one up when they will ship to Ca...

Any issue with the .1 engine warranty?

Wow... the gains for the .2 cars are impressive if accurate. I wonder how reliability is affected.

With this device, can you switch between multiple maps (factory OEM vs modified) on the fly?

Pros:
-On the fly map switching
-Flash at home solution
-Multiple maps
-Ability to do custom tunes
-OTS tunes generally pretty good (but these are only stage one)
-Typically have the ability to turn off CEL from catless exhaust etc
-PDK tuning
-Typically excellent support and updates from past experience with Cobb
-In other applications, AP flasher can be unmarried from your ECU if you decide to sell (e.g. selling car etc); with other flashes, you are typically stuck with the parts
-Good pricing vs. alternatives

Considerations:
-Degree of dealer visibility on the reflash (how easily is this detected)? This solution vs. M-Engineering ECU clone; this requires alot of dicussion because what if you purchase a vehicle that was previously flashed and dealer pulls warranty on you. Presumably there would be a time stamp and you could claim you didnt know if done prior to your ownership but not sure if that is enough to clear it with dealer. I suspect the ECU probe to ensure "clean bill of health and no reflashing" will be commonplace along with checking inginition/overrev history.
-Currently only at stage 1: timing of additional OTS maps for intake, headers (catted/catless) and other engine modifications
-Availability of pro-tuners in your area (or you can always go remote if you have a dyno around but no tuner)

FourT6and2

This would only be if you want a custom tune for other aftermarket parts like headers, etc. right?

M&Abanker4life

Correct - this is a flash at home solution which is the biggest benefit vs. alternatives

Larry Cable

same as any other ECU flash - (probably) voids

not on the fly (like pressing sport button) but once you flash the Cobb f/w onto the ECU you can change the maps themselves easily (as I recall from my usage on the 991 GTS)


I typically unflashed the Cobb from my ECU before I took the car in for service...

yes.

M&Abanker4life

Flash counter or other checksum (e.g. in some applications, operating hours are typically stored in multiple places in the car and need to match) is what I am worried about.
My question is if those things are obvious from the low level plug in a dealer does when you check in for say an oil change or regular service vs. a deeper inspection of the ECU that may be warranted during a warranty process (e.g. something much more catastrophic like engine or trans failure).

Larry Cable

That's why I uninstalled Cobb before going to dealer in case they reflashed it...

There probably is a total flash count somewhere but only con can answer your question definitively

Good to see this option finally available for our cars. At about 4x the price for the Accessport on my STI, there's certainly a Porsche tax added! Of course a much smaller market over which to spread the development costs.

Will be interesting to see reviews on the PDK tuning. The Cobb tuning for my Raptor didn't make a big difference for power, but the transmission tuning really improves the driveability.

Larry Cable

I had the same experience with my 991.1 GTS PDK...
