The world's first Lotus Emira I4 ECU

I want the flames! (Safely of course)

Doc and I (and others) who came from 4C world (and other makes/models) are used to having a spare clone ECU. I drove with my stock ECU in the trunk in my 4C while the tuned one was in. On that platform the cloned ECU would get vin locked to the car but you could just swap out stock and clone anytime you wanted. This was also a good way to deal with smog depending on the hardware configuration.

So some questions as we learn more are: is this same methodology possible? buy an ECU, place flash on that one and use it like a clone, keep stock one stock. Also, whenever there was a firmware update to the 4C, EuroCompulsion would get a copy of an updated stock ECU, then you would send your clone to them for updates and then they would place your previous used tune and settings on it. I don't know what modules or how many computers get updated whenever we get these dealer flashes and updates. Especially with the important transmission and fuel system control module updates coming.

Exciting! again, I am so looking forward to dialing out CEL's and adding some burbles, and whatever tricks the tuner is able to access in the car.

This is what we had for our 4Cs. One ECU with stock tune and one clone ECU with Eurocompulsion tune(s) on it.

Im hoping Boomgear (or whoever the Chinese tuner is) can offer something similar.

anyone know where the ECU is located and approx time to R&R?

under the engine cover, sits on top of the air intake filter forming part of the lid of the air intake.

edit:
it's basically the same as the A45s amg or CLA45s amg. Lotus modified/created a new tube that connects the side vent to the intake box instead of Mercedes tube that connects to the radiator area on their cars

Yes, 470 hp and 600+ Nm should be no problem, but I’d probably need some cooling upgrades to get that consistently here. Starting off slow, we can always take a step up later.

Going from 360 to 420-430 is a good first step for me

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.

Well that couldn't be simpler, a bit surprised its not in a conditioned space. However, the the intake air might help keep the assembly is a good range.
Thanks Milk242
