Nah, don’t worry. The Evora club will always be very small and exclusive.
 

Even ex-owners are welcome. Sometimes. 😜

Good job I’m in the Emira forum and not the Evora one then 😀

Woww!! All this numbers thrown away and so many people who can't even drive properly and fast 200hp 🙄

Sorry but looking at all this 'big hp upgrades' posts makes me feel like I am on a Nissan tuning Forum..

Absolutely, nobody has even driven it and all I keep reading on social media is talk about turning up the wick 🙄

The number of people who can't even keep up with a 101bhp Smart Roadster (including @Bravo73 and @bosshog 😜) says to me, power isn't the issue.

The Litchfield tune is for the older M133 engine. The Emira will have the new and totally awesome M139 engine. It’s a tuners dream. Twin scroll ball bearing turbo (large) with lightweight forged steel crank, forged aluminium pistons etc. The A45s version is making 421ps so it’s surprising Lotus have detuned it even more than the 382bhp base (non s version). I suspect this is to appease the v6 buyers and once they’ve run the old v6 out we’ll see more powerful AMG versions. The good news is that stage 1 remaps on the base engine are seeing 470bhp on 98Ron fuel.

A performance catted down pipe is seeing even more.

I’d love to know what the difference is between the s and non s version of the M139 engine other than boost/map.

maybe someone can elaborate?

 

Welcome to TLF.

What sort of car are you currently driving? You like superman by any chance?

You should duck over to the Introductions area and say hi in there as well.

This tuning potential (and more) is already in place for the V6, tried and tested in the Evora and Exige, ultra reliable (including the manual gearbox) and not too much money.

This is a path already very well trodden in the Lotus community, if tuning for power is your thing then you can still choose the V6

Do you remember that..?........with all those car emission controls California was leading.......😒

Will be tuning of the Emira by private persons in the next years less plausible......?

Some folks on social media have started to post about a new California smog testing procedure that is supposed to check for modified or non-CARB compliant software in vehicle ECUs, which I did some digging into. Using the link posted at the bottom of the screenshots I’ve seen, I followed it back to the California Bureau of Automotive Repair’s smog FAQ page, where the confirmation was clear as day: California is indeed going to start sniffing for tunes during smog checks.

To be fair, I think you can blame it on Lotus teasing us with HP numbers. Especially when we know both engines produce well over their advertised range. Smart move from a marketing standpoint. Imagine how easily we would sleep if we had info and could actually make up our minds. 😁

The UK government has traditionally been very 'friendly' towards all manner of car mods (probably because the industry is a revenue generator) so I think we would be amongst the last to suffer such curbs. To be honest I'm not personally bothered; I use enjoy tuning my own engines (gas flowing, new cams, balancing etc) but those days are long behind me, I won't be messing with my own Emira if/when I get it

His recollection is also very confused. It must be his age, or something.

The build process for the M139 is pretty epic to watch. I think it might be the engine to consider.

 

Welcome to TLF.

I presume you are looking to get an Emira by the sounds of it?

I suspect that Lotus are hedging their numbers a great deal due to this being a world car and needing to tune appropriately for available fuel in all markets. I think they are also sandbagging the 0-60 time so they can exceed expectations when the initial press cars get reviewed.

As Matt Windle said on one of the videos, the V6 should be essentially the same packaging as the existing Evora (416hp on EU/US super premium fuel). If the pattern continues, the AMG I4 will likely be in a similar state of tune to the non-S AMG45 M139 currently on sale in other vehicles (382hp on EU/US super premium fuel).  "Super premium" is normally US ~93 octane (average of RON+MON) or EU ~98 RON. My guess is for a 0-60 in the AMG powered cars of around 3.9s, maybe less. Journalists are getting that today in the CLA45s which has a little more power but WAY more weight to move.

In other places around the world, where available max octane is possibly lower, it may truly be a 360hp output car and only see 4.5s to 62mph/100kph due to far less aggressive mapping on that fuel. I don't think that will be true in markets like the EU or US though.

Premium in Australia is 98 RON. Made a noticeable difference to my Esprit.

Even if the California ecu tune detection is in place, you can still at least enjoy your ECU tune for 8 years from time of purchase until you have to smog the car every two years in California. I'm sure by the time you need to smog it there will be some method of defeating ECU checksum checks. Or you can stick to ECU tunes that are CARB certified tuners who are willing to go through the carb certification process.

I too have been trying to see if there are any physical differences between the M139 in the A45 and A45S and there aren't a whole lot of resources out there. Was trying to get P/Ns for parts in the head and couldn't find much. If there would be any major differences, it would likely be in the head or exhaust manifold. It's most likely just a difference in mappings.

My guess is turbo, intercooler, and mapping. Possibly exhaust differences too, but the turbo itself is the most likely. There may also be fueling differences.

Has Lotus a history of bringing their own tuning options to existing customer cars?

I know it's not quite the same, but Tesla offer performance upgrades for an additional fee.  Maybe Lotus could offer a performance pack for a few grand?

They did, but a long time ago.  The last one I can remember is the VHPD 190 upgrade for the S1 Exige, which could be done by dealers using a Lotus-warranted upgrade kit.  B&C did their own "Super 160" upgrade for the S1 Elise, which I think they warranted.

Lotus could have offered a supercharger upgrade for the NA Evora but didn't and aftermarket firms like Komotec stepped in.

[simonb]

I thought the VHDP was sold as 178(?) BHP as it was regulation compliant at that level, but you could upgrade to 190 once registered

One I drove when they were new was like a bag of spanners that would stall in an instant at below 1500 revs

[TomE]

You may be right.  I'm fairly new to S1 Exige ownership and know mine was done as a later upgrade to 190, whereas some were 190 from new - sold as "track spec".  They do need a bit of careful set up to run cleanly.

There was an official supercharger kit for the Elise s2 R to bring the engine up to SC level. Had mine installed by Christopher Neil/Oakmere. Transformed the car into something quite different.

[freefall_junkie]

There was also an official ECU update for the Elise S2 R and Exige S2 to lower the RPM of the cam switch. Had mine done by Hangar 111. It would be nice to think Lotus might offer remap upgrades for Emira owners in the future, especially for the I4, but somehow I doubt his will happen.

[MJON]

Emira for me is a GT car, nothing like Elise or the outrageous (in a good way) Exige’s. So the only thing I’ll be tuning is the radio 😉

[TomE]

With the voice control you won't even need to do that .... "hey Emira, play my driving playlist"  

[Evotion]

I could also do with a voice-controlled ejector seat for when the missus moans at me for driving over the speed limit.  I now no longer drive with her in the car. I let her drive so I can have a moan at her positioning

[snowrx]

The spoiler is supposed to be on the car, not in it. 

My missus threatens car sickness with any sign of spirited driving by me, but lurches down the road and through corners with constant corrections to no ill effect.
