I would only trust KomoTec for a full tune and power upgrade, however both H111 (Hangar 111) and ES Motorsport are hugely experienced and very reputable for performance mods etc. I would say they are safe hands to be trusted, based on what I have heard.

Dave at Seriously Lotus also get's a great reputation for tuning parts/performance upgrade parts.

2bular headers are a real work of it. Superbly well made, Etc.

I came into this world screaming and covered in someone elses blood. I'll probably leave it in the same way.

Thanks for the advise! What about the RRR upgrades? Like the ecu master?

Sorry, I have no knowledge of them. I am sure someone will be along.

The 250 cup model doesn’t seem to be as easy to retune as the original cup 220 & the normal model Elise with the 2zr engines.The ecu is the issue, I believe it’s the encryption Stopping total access,

Komotec kits direct or via  H111 are not listing the 250 model , 

You mention RRR they use the Ecumaster Ecu to great affect However so does Komotec and H111 , the only thing to remember is the ecu will have a different traction control system to the original, this may not bother some people , but it depends on what the car is for road/ Track

From my experience it’s best to use one company or at least confirm prior to cherry picking parts etc.

I have Jim’s complete system for my car, however to have the ecu tuned by Komotec I would have to go to Germany as it was not available in the uk to me.

Gutted as I was due there 2 weeks ago but There’s more important issues at the moment .

What's the best tune/ecu for the 250 cup? Planning to go for 2bular 4-1 manifold with test pipe... 

We offer an ECU package which will take the 250 to around 290-300. This requires an exhaust swap to a 4-1 manifold. The only changes are the ECU and lambda sensor with our kit. 

Benefits to our system is you have full flexibility, something you aren't happy with on the map you can change it, you prefer a different traction set up you can change it. Plus it is still compatible with the AIM dash and Ecumaster ADU amongst others if you wished to install one of them as well.

@elise 147 komotec have the 285 - "We developed this performance phase to give the new Elise S / Sport 220 / Cup 250 a little more performance."

Thanks for that , will be an interesting read ,it is a more serious upgrade with a totally new ecu , which is the only way the tuners are dealing properly with the 250 cup. There are a number of 250cup owners on the Facebook site that have had the the full exhaust systemS and have had mil lights on due to emissions codes and fuelling issues.

I see... upon researching and reading all the reviews/videos, I think RRR is the way to go... it seems they got the most power and the easiest installation since it's a plug & play system. Will also get the full exhaust from 2bular, hard to decide which manifold though... test pipe or the silenced de cat pipe 🤔

Hi Stephen.  So, whilst it's not fully announced in terms of details, we are now able to offer OEM ECU remapping for those who wish to use alternative suppliers exhausts in the KT kits.  I hope to find some time to sit down and crunch the numbers and type the words soon!  We may need to have a quick chat...

I believe KT can programme the 250 ECU, we have certainly done one or two, when they first came out.  Obviously the EMU is an option, as long as you and your insurer are happy with the changes to "DPM" - not all are!

Would an insurer be happy if you changed the OEM ECU either? Its a modification either way. 

We have proven solutions for the 220 taking it to 270 with just an ECU and a good exhuast. We have 220-300 using injectors, a smaller pulley, charge cooler kit and a thermal gasket and for the 250s we can make 290 easily with just the ECU, probably push 300 with the charge cooler kit and thermal gasket.

They tend to be more tolerant of a "remap" rather than aftermarket ECU, yes.  Some are fine, others aren't, based on feedback from some of our customers.

It's good that people have a decent choice to suit whatever they want from their car.

I just ordered the RRR ECU and a 2bular exhaust system... they claim my car (250cup) can go up to 290-295hp with this simple upgrade! Sounds worth it if you ask me, can't wait to get them! 🤗

I returned the RRR ECU and just asked for full refund... it seems the ECU was not "plug n play" type, car won't crank after installing it. My car probably has a different version or region. After they helped and did a team viewing, the ECU didn't seem to have any file in it... they said it was corrupted or something. I'm just glad they sent me a full refund after sending the ECU back to them. I installed the full 2bular exhaust and it was AMAZING! Quality and sound of the exhaust were A+++, highly recommended! I shed around 6.74kg from the 2bular system against the stock exhaust... not bad considering it's already a long tube manifold design 🙂

Do you mind sharing the 2bular full exhuat options you upgraded? Was it just 250Cup/SE ROAD Exhaust System? Including any 4-1 Manifold and HD Cat?
I assume you are running stock ECU now with the 2bular full exhaust system, am I right? Thanks!
