Sales BS. Higher numbers sells more product. There is no way the JB4 box is making anywhere near the figures they are quoting.

Interested to hear your thoughts on these, especially their positive or negative affect on ride comfort. Had Nitrons on my Yaris GR and they need rebuilding after only 3.5k so wasn't overly impressed. I hear MOTON do a coil over for the Emira too which should be of comparable quality to Ohlins.

Same here.... although I'm most likely going to do something with Cobra and their Nogaro seat. Had them in my Yaris GR and they were absolutely perfect in everyway.

Good question, I'll have a look and report back

Yes mines the 360bhp UK spec. Bearing in mind the box achieved a relatively easy 50bhp and 50Nm you should see 450bhp on your US i4's. I'd love to time some runs using a GPS draggy box, with the DSG shifting in track mode I reckon it will be very quick now

Good day today, TDI got the car on the dyno for some base runs and then tweaks to the software in their box to see what's possible whilst checking temps and error codes, etc to ensure the car was running fine and happy. Baseline run was interesting: 379bhp and 420Nm. That's more bhp than I...

Mines on the Dyno on the 15th with the guys at TDI to get some before and after figures. I dare say they'll tweak the map too and roll out a software update on their box.

All 1st editions are 360bhp.

Love the look of your 4C, I'd imagine that was a bit twitchy in OEM configuration on track. Good luck with your Emira, based on your approach to the 4C you'll most likely end up with a cracking track car. I've spent more money than I'll ever admit to tuning my V6 Exige engine and trans to...

360bhp link 400bhp variant link

I paid £58k for my 2024 vivid red 1st Edition i4 with 400 miles on the clock. Not sure on the exchange rate bearing in mind the golden wonder is giving the global economy a heart attack right now.

Once you know how it's a 20 min job

I'd bet my trousers it's more than 400bhp. Dyno is booked for 15th so I'll report back.

Ok, final testing completed and everything runs exactly as it should. I've seen no significant increase in coolant temps, zero engine check lights. The car runs great, pulls hard and being turbo charged it has responded well to the box with a noticeable increase in mid range. In track mode it...

Yes

The product will come with full fitting instructions. If you have a jack you can fit it yourself or any garage should b able to, takes 20 mins

Ok, so big update today. After a lot of development, fact finding and implementing several tweaks to work with the Lotus software on the AMG i4 the tuner has their solution fully up and running. Their hardware inc wiring loom, tuning box etc is connected to the relevant sensors and everything is...

More work carried out on my i4 today. Whilst the engine and trans are identical to the A45S, the i4 Emira has some unique hardware that's proven challenging. It's a case of 2 steps forward, 1 step back. Fortunately the tuner seems to be enjoying the challenge and so far at least, problem solving...

Any Lotus with a manual trans and the V6 Toyota uses the same EA60 gearbox albeit with some minor tweaks to ratios. This includes the series 3 Exige, Evora and Emira

Yes, 460bhp isn't a massive number but it definitely blew my V6 trans apart and Emira owners deserve to know that it can and sometimes does happen. I was running a TVS1900 chargecooled supercharger, MOTEC ecu and other associated hardware to mitigate the extra stresses of track day driving and...

No BS here. My V6 Exige trans let go at 460bhp and I have the bills to prove it. The engine can handle that power more reliably but the gearbox is most definitely the weak link and I'm not the 1st to find out. Ring Komo-tec or JUBU, they'll tell you the same

Be careful - my V6 Exige blew it's trans at approx 460bhp. Gearbox is definitely the weak link

Good work, very useful

Hi, did the o2 spacer work?

Its going to be a plug in solution similar to JB4. If its a pain to install the tuner will offer fitting for a small charge. I paid them to install their box into my g87 M2 as one of the sensor locations if a real pain to reach.

My exige 380 (same engine and trans as the Emira v6) blew its trans at 460bhp.

Hi all, I'm working with a well known tuner to develop a tuning box for the M139 engine i4 Emira. My car is being trialled over the coming fortnight so I should hopefully have some further info and numbers to post up soon. It will be a plug and play solution, easily removable for routine dealer...
