Quick scan through the video identified spotty teenagers in worn hoodies making animated comments about used cars - did I miss anything?

Also needs weld on fender flares and roof scoop. These will do:

Ultimately there is inherent limitations in the transferrability of the tunes between the cars, as all the cars are different (and certainly different when people start changing the hardware). Of course decent "mail in" tune from a knowledgeable professional will be much better than kamikaze style quick effort from someone who did not put time and thoughts into the effort, but in the same way car-specific maps based on many hours of logging the same cae will be better for that car than even a good set of maps from the different even similar car. Quick search leads to this - https://www.lotustalk.com/forums/f171/tuning-software-stock-lotus-ecu-162082/, but I understand they pulled it out from end users access.

In fact it is not that difficult, given you start from the base tune (which is either base ROM from Lotus or pre-defined for an Exige V6 maps of the aftermarket ECU, which many of them would come with). You then only need to make sure you stick to the ground rules: Put in place all the key support infrastructure (OBD logging device, logging software configuration, WBO2; other sensors as needed and dependent on what is available from stock) Understand the basics of internal combustion engine operations and how different parameters are interdependent (basically excess intake pressure, AFR, ignition timing, main corrections of these) Make only incremental changes to one parameter at a time Log everything and spend good amount of time studying your logs, especially when putting the car to a good use after the changes (temperature makes a big difference between logging runs and 15 minutes trackday session) Adjust to mildly more conservative settings every time you encounter knocks I've spent good amount of time mapping my own EvoIX which then has done more than 50k miles on my own maps without any issues (knock knock knock). Happy to talk through this topic, if interested.

@k20Rob, interesting thing is that they do with lower excess pressure on the charge cooled setup. Which should mean that the extra power is obtained through much more aggressive timing and leaner AFR, possible due to lower temperatures. This should also positively impact fuel consumption (obviously still higher than stock, but not higher than non charge-cooled more powerful than stock setups), which would be a very welcome side effect for those going to the trackdays and having to refuel after every other session.

Maybe for you? I've asked for a noise-insulation, given it is very light and supposedly makes some minor difference. Intentionally asked for no carpets, as prefer to see the aluminium tub glued together - it is somewhat special.

There seems to be a veil of secrecy around remapping ECUs of Exiges. I did not research the topic much, but would not be surprised if there is a compatible equivalent of ECUFlash or something similar to work with. Alternatively, can't go wrong with More, especially if the work is already done to have it PnP -

Just out of curiosity - in what units is this measured nominally?

Power is primarily the product of burning the volumes (hence intake pressure matters) of air-fuel mix (hence fuel maps matter) at the right moment in time (hence ignition maps matter). Unless the maps are more suitable to one of the two physical setups (resulting in one of the two knocking and adjusting to the observed conditions), there should be no objective difference in power. Of course, the above is an oversimplified description, however it still is correct.

There is an app called Ginventory, where they try to provide pairing suggestions

I'd be keen to know how indicative or obligatory this is. In my experience they use random valuators referring to semi-independent Glass's guide

If you're going to use it for trackdays and don't won't to be too sensitive about noise limits - Sport 350 it is. 5"11 shouldn't be a problem at all, I'm noticeably taller and have no issues with either sitting or getting in and out (although the latter is always an acrobatic event)

Ah, that makes it clearer - I was just really curious if I've missed something from the one above

How do you guys have this impression from seeing a camera showing a rather serious guy chewing a gum with some funny passengers in the car?

This looks like buying yourself a trouble wit your own money - have no idea why would that make sense...

It is last 10 years of debates of "Motul vs Redline" - ultimately both will do perfectly well. I personally always used Motul and never had a problem with it, but the same is true for many other people using Redline.

That's just a greedy dealer then. I paid just under £1,000 for a brand new one with minor drilling works done as well.

Some connection becoming loose when hot? Anything around where you were making changes before the trackday? Or maybe some witchcraft was there in Silverstone, as my engine misfire also went away and there is nothing for B&C to report on after checking it during the service just now.

Can't agree more with this. One would have to be truly somewhat special to deny GT3 RS a status of a spectacular piece of automotive excellence.

What's better reason to go for a pre-wash drive then? This engine is fitted to many Toyotas and Lexuses, I bet they have start-stop fitted on at least some of those - nothing will happen to it.

To be honest I'd rather prefer a light turbocharged I4 (probably somewhere between 1.9 and 2.5 would do) - less weight, more power achievable, less space needed

I'd never bother with anything else other then OEM oil filter in not a heavily modified car.

That's the reason why Scott is taking the pictures and not the visitors.

The video itself looks a bit targeted at the spotty teenagers (so we should not care at all). No timing, no adequate comparison, not even any adequate driver ("babes"??? eh?). Sport 350 with decent driver will make it to around 12.0s 0-402m, which is a rather totally unachievable performance for Alfa 4C.

Not sure it is any really needed in an Exige - it's got a rather favourable combination of weight, brakes size, tyres size. Did you experience any issues with the brakes?
