So are we saying that the standard 260 map is OK for ‘normal’ temps but if we get 25 degree plus temps there might me an issue
Boothy makes a valid point though on warranty. On the std 260 Cup cars you only get 12months warranty and I bet none if you retro fit the 260 upgrade to a standard 220 or 240.
SO I guess the question is would I see benefits in AFR and potentially performance gains from re mapping my 260 ECU ? [/quote]
IMHO Lotus would not sell a car with any kind of dodgy map, the reason the cup 260 has a shorter warranty is because its a cup ie track car.
The RGB has a full two year warranty and runs the 260 map.
It would not surprise me if the map is not varied dependant on the country of sale tbh. Other than that it will be engineered safe.
I really do not believe some blokes with a dyno in a shed can do a better job.
I would hazard a guess that Toyota assigned some engineers to oversee the process of the Norfolk Turkey Farmers mapping their 2zz too …
I can’t see them risking their reputation for reliability without a close eye being kept .
So you wanna put a Toyota cheese gearbox on those crackers ? I guess Lotus engineers were smart going with that too…
The tune is fucckin lean and on the edge… Proper AFR’s are needed in the entire RPM range not the last 500 rpm…
Trust me the Lotus tuners are not all that hot since they have never come close to a proper tune so far…
They can’t even run a supercharged car on track with the knock sensor turned on due to all the noise from the supercharger…now that’s rich… :whistle:
Oh and don’t forget the S roof intake, ya gotta laugh when you see their engineering skills…putting a A/A intercooler on top of an engine without any heat shielding… :whistle:

Do Lotus let you keep the warranty if you track the car? Genuine question.
And on the subject of maps. I did a better job mapping my 2ZZ MR-S first time than lotus did with my S1 190 ecu. That was a really bad map they had there.

Times have moved on though and we are talking about a production spec engine not a highly tuned vhpd race engine being used on the road.
Been watching this one from a distance. TBH I think I’m with Frank on this one. He’s just trying to keep you guys safe. You either take the advice or you don’t but I can’t understand why you are being so defensive of the Lotus map. From the plots here its running pretty lean. Full stop.
When I got my Exige back in the day it had the standard A series ECU. Car stalled coasting into roundabouts. That’s the original map that they put on these cars when they first introduced the Toyota. So bad that it was subject to an upgrade on request. Not just a remap but they had to replace the whole ECU with B spec.
You’ve all modified your cars to a greater or lesser degree already so why not take the next step and get yourselves a custom map (Sincs or one of the replacement ECUs that’s coming out)? Perhaps not as bling as the new exhaust/wheels/suspension but if it saves you an expensive rebuild well worth it.
I’m sill with Frank and Will, if you want it to be the best it can be get it mapped, the Lotus map is there to pass emmisions and work on the road. 13 is too lean for a SC car for use on a track and dubious for me on the road…
When taking the next step and fitting a full exhaust pully etc then I will no doubt buy the custom ecu and have the car mapped.
I am still not totally convinced by essex after the advice I was given early on which was imho a we would like to sell you a charge cooler pitch. If they will not put some effort into mapping an air to air car then it might be worth the trip.
However as my car is I am not convinced at all I need anything other than the lotus map.
