Tuning Tech Frank Smith/Dundon Motorsports ECU Clone and Flash Tuning
In conjunction with our header development we've been working with my friend and european tuning expert, Frank Smith. What we wanted to do was to give everyone the ability to keep their stock ECU unmolested.
To that end we've devised a way to clone your stock ECU and allow you to keep it on the shelf to reinstall for warranty work, or for resale. We send the clone with our stage 1 tune on it and a flash cable for ongoing updates.
Stock ECU for GT3 and RS is $1045.00 (based on 2/10/16 Porsche pricing)
Cloning Service (requires you to send your stock ECU to TTFS) is $250.00
Stage 1 Tune for GT3/RS with Dundon Headers is $1950.00
Flash Tool and ongoing tune revisions is $400.00
In addition to HP/TQ increases we're adding sport exhaust button control so that open is always open when pressed, and normal operation when not pressed.
We will doing ongoing development with the tunes and this is why we are offering ongoing revisions for free. We plan to have Frank out regularly to the Northwest for dyno, driving and track day tuning, and will be doing remote tuning and updates with him as well. The current tune is very well developed, car drives smooth, no issues, the further refinements is as we find things.
For our 991-GT3 DMS Headers the gains over the stock tune are 10-15whp. previously we were seeing 40-42whp MAX GAIN over stock, and peak HP gain was 32-37whp based on run variance of the inconsistency of the stock engine.
After the tune and in its current state which is DMS headers, side pipes, K&N air filters, and STG1 TTFS reflash, we have a 50-55whp @ 8100rpm max gain and a peak HP gain of 40-45whp.
current average gains we are seeing,
3000rpm - 24wtq 14whp
4000rpm - 34wtq 25whp
5000rpm - 34wtq 33whp
6000rpm - 28wtq 30whp
7000rpm - 32wtq 43whp
8000rpm - 30wtq 46whp
8400rpm - 29wtq 46whp
I will continue to update this thread with dyno's etc... related to the tuning we're doing with TTFS and Frank.

Great info. Does this tune work on the 16 RS? If so what are you getting in average gains?
How can we load the tune? Just through OBD flash? I'm overseas so it'll be hard sending the ECU to you…
We can write the tune with our OBDII cable, what we may need is your Ecu first anyway so we have the appropriate SW number.
As we do more of these this is will become less of a requirement. Where are you located?

Working on getting the RS with headers and tune now.
Also Frank is working on getting a stock RS tune as well. As you can imagine, finding an RS is tough, finding an RS owner that will allow a bit of safe testing done on their car is even tougher...
This is one of the reasons we were so thankful that SSTHO let us put the headers on his car!

Thanks, we believe there is more in the RS and that there is a bit more over 8500 in the GT3
Say some one is running the cloned ECU and is out there just banging that crap out of it at 9k+ and an overrev is logged, is that overrev history when you re-install the factory ECU? Or does the PDK eliminate an possibility of an overrev situation?
Another scenario, what if someone is running the clone ECU and has an engine fault, those fault codes are stored on the cloned ECU. If you need to take it in for an engine fault under warranty, how do you handle replicating the faults with the factory ECM?
The errors, over revs, mileage are all reported to and stored in the cluster, not in the Ecu. We checked... Also no possibility of overrev in a PDK car, So no issues and no maliciousness with running a cloned Ecu and swapping back to the original...

A lot of info in these cars is stored in the cluster not the DME
As for faults, yes, I believe if you have the tuned ECU and record a fault, it depends on what it is and how it is handled. Yes if there is a fault issued and stored and you swap DME's it will be erased. However depending on what it is the fault may come back right away or shortly there after, if not then it may not be a serious critical fault. Depends on each scenario.
example, say you have a 2014 and you start having high RPM missfires above 7000rpm. Something like this if it is a rocker arm wear issue, then that will be registered with either DME. so swap DME's and drive again so it records the fault then take it in. If you have a good dealer and relationship with them then you may not even need to swap the DME out as there is nothing related with the DME flash and failure of the rockers.
Actually you can get over revs in range 1 on the 991.1 GT3. If you have the car in manual and sport while flooring it you may record range 1 over revs. It feels like the engine has fallen off a cliff. I did this with a tech in the car. We went back to the shop and read out the ecu. I had about 30 counts in range 1. Previous cars not a big deal but Porsche now says 'engine damage possible for range 1.' Some dealers might hold your feet to the fire on that one. Just a thought.
I did the same thing in my 11 GTS a few years ago. It doesn't appear to happen in drive + manual. At 9000 RPMs 30 counts is a miniscule amount of time. 0.07 sec?
