I4 (AMG-2.0 Turbo) DCT gearbox software update from LOTUS - mid August 2024

There is a software update that seems to have been released by Lotus for the gear shifting algorithm of the Emira AMG-2.0 Turbo. This may improve the perceived delays when using the flappy pedals, and it is said to even improve going from forward motion into reverse. It will be interesting to hear from owners, that gets this installed, about the extent and subjective feel of this update.

Did anything more come of the software update for the 40bhp increase?
Anyone know what the software version is, if its actually a thing?

Car goes to the shop on Wednesday and if there is an upgrade, I want it

Got my car back and pparently all updates applied. Power bar still tops out at 360

Does it feel the same though.... the bhp on that power bar may not ever show the correct hp. It may only go up to 360 even when your running 500hp, as it could be linked to throttle position (for example).

The power meter is certainly calculated, however it's probably relatively close.
You can put this to bed for ~$100. Just buy a Draggy performance meter, the new ones are very easy to use and pretty accurate (with a level test area) .

360 Hp with a small driver (150lbs) + launch control on a cool day should yield ~4.2 sec to 60mph without rollout

400hp same conditions ~3.8 seconds

That's an interesting thought about the power bar only going up to 360bhp, here's a picture of mine and you can see Its indicating 389bhp, but you can also see the power bar does extends a little further to probably somewhere around 400bhp, maybe someone else can confirm when they see 360 on their power bar is it topped out or is there still space for it to go further. Hope that makes sense

This is what my 400hp I4 displays. I see 480Nm and 411bhp max figures (not at same time, as torque is a little down by the time max power is delivered).

Have an Audi RS3 8 Y, a few days ago, just to get an idea of actual performance, I done a quick test, with a draggy, on it and my Emira, on same bit of road, one after the other, achieved 0-60 mph time of 3.59 for the Audi, and 3.91 for the Lotus. I’m fairly satisfied that the performance figures are reliable.

Bizarrely, I also have an RS3 8Y and I would add that the Audi pulls harder but there is definitely more turbo lag in the Audi.

Agreed , I would like to get rid of the lag in ordinary drive mode, and performance mode can be very aggressive. The Lotus responds well in all modes.

3.91 for the Lotus.

You're running a 360 hp version, right ? if so 3.91 to 60mph is great. Assume this number is with roll-out subtracted.

Yes, 360hp version, I just followed the instructions for the the latest dragy DRG70, and got the results.

Your 411hp sounds way more aggressive than my 360hp. Wow. That turbo sound is definitely more noticeable as well. I need a tune!

On the results page bottom left shows 0-60 (1 ft), that's with roll out subtracted, this is what Car&Driver uses. I have last years draggy; middle of report is 0-60 with rollout. A 3.9s is very good results with rollout.


[achieved 0-60 mph time of 3.59 for the Audi].
The Audi S3 with a DTC has the same power output as the Turbo SE Emira and the Audi is 400 pounds heavier, but Audi has AWD. Did you have any wheel spin on your Emira 0-60 run? If not, based on these result I would expect the 400hp (+) version to run a hair faster than the S3.

Car can be launched in sport or track mode, I launched in track mode and don’t recall wheel spin. Will be interesting to see how the 400 hp version performs.

lynchy73 are dragy performance meters available in China ? would be interesting to see what your Emira version (411hp) run a 0-60mph​

I’ve since added an Aerie Ti Exhaust and Aerie Sports Cat, so any test I do now may not be representative of a standard car. I got circa 4s 0-100km/h using a phone app.

There is some wheel spin in Launch Mode. Without launch activated, it’s pretty gentle off the line.

Yeah your spot on, it wouldn't a good baseline eval.

Did your Emria performance gauge read 411 HP prior to all your modifications?

Are you happy with the sound from the aerie exhaust and sports cat, and have you had any cels?

 

[GasperV]

@lynchy73 how was the installation (fitment) of Aerie Ti Exhaust and Aerie Sports Cat?
Are you getting any error codes?

Could you please upload the sound of cold start and drive by. How would you capare stock exhaust vs. Aerie Ti Exhaust with Aerie Sports Cat?

Thank you.
