August Software Updates (i4)

[Ch0wd3r]

Went to the dealership for something and had two software updates done (was told they are part of the August update package). The codes are: QBS-131-25010 and QBS-131-25011.

Anyone know what these are for? Was hoping one of them is for the DCT (maybe wishful thinking for it to be the same recalibration update stated for the 2026 models), especially since my car has the low gear bucking problem. Drove home after the updates and transmission felt smoother, but could certainly be just placebo

Hey there……first trip to the dealer for my I4’s first service…….after three hours downloading flashes, I’m told it may take another 5+ hours…had to leave the car overnight, and of course, the mechanic was off the next day…..that said, it was at least 8 hours of down loads so it was either a ton of codes or dealers lack of a good internet signal! Now awaiting for Monday to get the code updates. The car does “feel”
better and I have yet to feel the bucking that was present during low gear shifts……..time and a few more will be needed.

Have you noticed any bucking after a few weeks or does it seem the software update improved things?

For what its worth, I haven't had any visit to dealer or updates since that early August visit, but still gets the bucking from time to time (although less frequent).

Thanks for the update! Bummer it's still there, but glad to hear it's at least improved. Does CarPlay/Android Auto disconnect less?

I use Android Auto and it’s never a big problem for me. If it disconnects, it only does it within the first 5 minutes of a new start/drive and it usually reconnects itself within like 10 seconds (and only once per drive).

Yeah I get the exact same behavior with my Android Auto as well. When I did a long road trip it would periodically disconnect throughout the trip until I plugged in.

Sorry for the delay….this is my 3rd Lotus and after the many flash updates over the years - I never could feel a difference. However, after this flash (8 hours) I have yet to feel any bucking or surging (was usually 2-3 gear). And all truly feels smoother - shifts - and better drive ability. I love this car, and now, even more. Having owned a great Evora with the “6”………the I4 is the way to go…….

This is great to hear. Thanks for the update!

Car just updated ( I4). Lag time between shifts using paddles reduced to the point of no delay.

Sorry I'm a little out of context....Is it a new shift update? Or is it your first update after a while? I had mine updated in august, and even though the lag time between shifts improved a lot, it definitely has plenty of lag still.

It’s my first update since taking delivery December 24. Lag is virtually gone. 95 out of 100. That good. If only they get rid of the double shift to get it in gear.

I don't know, it definitely got better, maybe I have high expectations, or it's the past PDK experience or the kart racing...but this transmission feels unresponsive to me, even after the upgrade. Paddle downshifting is a real pita.

I had this update done before cloning and shifting is a little more agressive and a little faster although my SA kept emphasis it has nothing to do with the transmission

Thanks for your comments. I note you say an update was made before cloning. Is it correct that you have installed a cloned ECU and that the update appeared and worked.
Was the update undertaken by Lotus themselves? Did the service department know your car is operating on a clone ECU. Are they prepared to update your car now and on into the future?
Your response is keenly anticipated, thank you again.
