You can easily going from 360 to 430 via JB4 with no issue. Id recommend go the easy way. The real merit of Hacked ECU is making your 360 to 470 or more, that's something out of piggybacks capabilities.

Map3/4 got more torque in the mid low range, but eventually gets the same final output in the high rpm, due to the limitations of the fuel you choose. Physically, they are faster than map2, however, might be marginally the same in a practical run of track, because you only use the high end rpm...

Interesting point. If V6 Auto performs pretty well, then It might be a good variant that balances speed/Comfy of I4 and Sound of V6. Plus, there's a 500hp+ mod package awaiting. Sounds promising.

It will be announced if it can be announced.

Emira ECU has been hacked and can be tuned. (Don't ask me the source) For those who are seeking 500hp+, it's a good news. For those who wants just stage-1 power (+60hp), JB4 is actually plenty enough.

What torque spec should I use when threading the spacer studs + nuts to the hub on an Emira using separate hardware? I hit alerts at around 40 Nm—is that normal or too low?

Yes

360bhp I4 after JB4: (using Ron98 aka 93AKI) Map1: +37whp, +36NM Map2: +53whp, +48NM Map3: +56whp, +65NM Map4 above: no test Ron98 is not enough for Map3, the torque difference only works in the low rpm range (3-4.5k rpm) Anyway, now the car is blistering fast, definely worth it.

Without E30, there's not much difference between map2 and map3. Map2 is quick enough.

360bhp i4 after JB4 is around 420-430 bhp

Just curious, Is the JB4 tuned 2.0T going to break the DCT gearbox's torque max limit? Anyone with the gearbox spec info?

May I ask a technical question? Which fuse did you unplug when testing dyno? Cheers

How many meters are required for AMG I4 installation?

5V USB powering 2 units at the same time? No issue? That's amazing!

Sure! Been 6500km, tracked twice, endless mountain sprint runs, fantastic car.

A fast good run.

Usually I use Track Mode and don't feel any special effects, but it is just so balanced.

Good job! waiting for your good news!

Would like to see more details of your testing!

Sounds like it's a design flaw, and a good reason for an exhaust upgrades! 😁

Is defective injectors very common in Emira now? Is that fuel quality related or just simply the product defection?

If pops and bangs disappeared after CEL is on, I'd say the power might be detuned a little bit.

How's the condition of the later batches? I think they've fixed it already?

That's true, but as an owner of 3 lotus cars, I would say before Lotus could know how to respond to this problem, it will save you lots of time and efforts by knowing how to adapt with the problems. It's just a LOTUS thing.

Since taking delivery of my Lotus Emira, it has been a thrilling companion on winding mountain roads and two track days at Lihpao International Circuit. While the car’s performance is undeniably engaging, my ownership experience hasn’t been entirely trouble-free. During the initial...

The truth is, there's none yet.

Just intalled the downpipe and drove back home. Haven't really pushed but slightly reved a little. Quick thoughts: faster throttle response, obviously more torque now (the torque meter clocked to 430NM very early and obviously it's more than the frozen 430NM, I would say 480NM is quite a fair...

I've run the stock 360hp version dyno test. Now my downpipe is ready, wait for my results...

And....the purpose to run this dyno test.... :cool: Wait for my next post....

I'll check tomorrow
