Transmission Tune - 2018 S5 Sportback?

[pstonge]

I have a Unitronics 1+ tune and would like to tune the transmission as well but they have not come up with a TCU tune yet. Any ideas or suggestions? Another provider?

​​​​​​​Thanks.

IE and 034 buth offer ECU and TCU tunes for that car.

While it’s not popular, I’ve mixed and matched ecu and tcu tunes from different company’s with no issues.

Any preference? Best pricing? Thanks.

If you see yourself changing tuners in the future go with whoever you like since you will need to buy a new cable again.

My opinion is IE has more options for drag racing, shifts faster and harder under full throttle amax. Fixes starting from second gear from a stop in auto, and downshifts sooner for more responsiveness. 034 is smoother, manual shifting is quicker , still shifts fast under amax but less brutal.

Don’t forget if you want to change completely over both companies offer huge switching discounts of 25-30% off.

I am running Ecu stage 2+E85 and 93 tcu stage 2 034 motorsports on my 2018 s4 the shifts are crisp.The drivebily is oem,when in S mode you can feel the shfts and the pop and bangs are addictive.
