ECU Tuning Questions (Detailed)
#76
Or was there a HUGE shipment to North America with old firmware and they have been sitting in warehouses for YEARS? <---I suspect this is probably what happened. Looking at the electronics involved probably $20 of material and the R&D costs were recouped a LONG time ago.
But agree that MyGenius worked just fine for my needs and was 10 minutes to swap tunes in the garage. Much more convenient than needing a dealer.

Although I would not go with a Cobb solution using the current OTS maps, to me-having something in hand to resell afterwards in the event you get rid of the car gives me some piece of mind. Love the results and testing/calibration with the APR tunes, but I would kick myself if I paid for a tune and then had to get rid of my car for whatever reason and just lost all the money spent on the tune since there is nothing to recoup. Case in point for me-I had a 981 gt4 with a cobb pro tune. I traded the GT4, then was going to sell my accessport and purchase one for the 991.2. Luck has it that I was able to send my accessport back to Cobb and they upgraded it to work on the 991.2 platform for a few hundred dollars. Had I gone with a OBD2 dealer tune, I would have had to buy an entire new tuning solution for the 991.2.

Slightly off-topic. but cant you use either a Cobb AP or a MyGenius to clear maintenance lights? Also been considering a NAV-TV (for audio upgrade), I believe you need an OBD solution to add it, maybe MyGenius would solve that problem as well.

FWIW I will go with a Softronic Tune this Spring for the 911 GTS. The MyGenius is nothing fancy, but works. Have used it for my C63, and will be using the same setup (different MyGenius) when tuning my E63s.
Picked up a Dragy yesterday, waiting for Spring to come. For some reason I was envisioning a device 5x as large. The size of a stick of gum.
Not in too much of a hurry as I love winter for the skiing

If you can wait for spring to arrive in Canada will post Dragy results.
I only view a dyno as a tuning tool. As I won't be 'tuning' will stick with Dragy, mainly to see how much slower my car is than my buddies McLaren. Bench racing FTW. haha.
FWIW I had my Subaru pro-tuned and it was on the dyno for several hours, run after run after run In that case I was all for a dyno

Have only used MyGenius for changing tunes, never looked into seeing if it could read or clear codes / CEL..

Will report / create a thread when tuned and spring arrives.
As for the Dragy unit, for some reason I envisioned it being much larger, but it is the size of a pack of gum / size of my thumb.
I have seen some pretty creative things happen with dyno runs. They are great for working on a tune / versus street tuning. But at the end of the day the data from 1/4 mile, 60-130 mph etc are telling and the Dragy unit seems very consistent between runs, and correlates very closely with drag strips. Downside to running on the street is traction, so the 60-130 mph run helps eliminate that.

Afte skimming this post, the most obvious suggestion from my point of view for the OP is to buy a power powerful car and call it a day. Many won’t buy a tuned car on the secondary market because of potential issues. And many don’t need more power. Why did you buy the C4? Price and ability to tune. Buy a 991.2 4GTS. Or at least take one for a drive. I think you will be very unhappy if you have problems post tune.
Problems post-tune are very rare.

No mention of the Litchfield tune?
Highly respected outfit, offered on Cobb AP, can remote tune based on logs, and retune as you add mods. Each retune is $300. Can all be done in your driveway and removed at will.
Many articles on the Litchfield Carrera T in professional publications giving the car a 5/5. Also a few YouTube videos out there.
Tuned for everyday drivability and reliability. Used by the owner Ian Litchfield on his personal Carrera T.
Just throwing it out there, as I was considering this myself. I have to confirm with them that they have a 91 octane version of the tune. Disadvantage is that Litchfield is located in U.K., but mitigated by remote tuning capability and that the tune seems to be solid and ever improving (given that it’s his personal car).
No bias here, just reporting my own research so far. The Litchfield car was what convinced me to buy my T, as the articles demonstrate the incredible growth capability of the 991.2 base platform.
Good luck, all.

I got a few moments and was able to speak with the tech dept at APR, I just called the normal number went through the prompts and it took about 10 seconds for someone to answer. I was very impressed with the gentleman's answers to my questions as he had no prep time and didn't know what I would be asking. I updated a couple things on the pro/con list for APR, but was able to confirm that a home-based solution is coming (maybe summer 2021, but no promises). At the bottom there is a table of HP & Torque claims from each company, where it says "(calculated)", i increased their percentage gains to the stock numbers with a calculator. The Cobb numbers seemed a little fishy there still but i put what they posted. Ignoring the Cobb, Softronics has the largest power and torque output by ~2% on HP and ~8% Torque to the next closest tuning solution. The chart (at the bottom) didn't copy and past as well as I would have liked it to but i think its still readable. I will continue to call other companies as I get time but here is what I have so far for updates.

As far as R&D that's subjective on what the company or employee's already know as you dont research a known and some companies may need more people to fill that lack of knowledge. So would 5 people looking for an answer be better than the one that knows it?
Like Ive said calling or emailing would have answered the questions .....

Well I wanted to make a correction in that we do offer full custom tuning and always have and it has always been listed on the website. Granted it doesnt specifically list the 991 platform yet it still applies. https://www.softronicsoftware.com/po...m-race-tuning/

I still believe my above points hold true as for answering questions publicly, not sure how forum is much different from an email short of not public.
