  1. Oh I was hoping Lotus might be able to use Merc engines.  Geely has a stake in Daimler if I'm not mistaken?  I would have thought Mercedes engines would have been a better fit for Lotus rather than the Volvo engines that many people were speculating.  But then it is a Lotus tradition of taking a very average engine and making sound and feel great, so I'm sure even with a Volvo engine the car will be great.

    The extra tech to bring into line with German cars I think was inevitable if Lotus want to go for mass market.  Hopefully they are smart about what features they choose and how they integrate them in.  If they can implement them in away so that for people who prefer basics are agnostic to the tech and its almost hidden away running in the back then that shouldn't upset too many people.  But then cameras, sensors and wires all have weight so you don't want them there if you are not using them.   hmm thats gonna be a tricky one to get right, fingers crossed they get it right.

  2. @ILLATOUCH great work, please keep us updated with progress, I find this stuff really interesting but am total newbie hopefully some time in the future I'll have the knowledge to give something like this a go.

    However hope that they are considering profiles as a drop-in performance upgrade for standard engines as well as profiles for built engines, as going too far would require changes to engine management and many would not want to go that far.

    @IanA I believe Komo-tec can reprogram the Lotus ECU, they don't require an aftermarket unit installed.  So while it would still be an extra expense to get a new tune it wont be as expensive or difficult to add a aftermarket ECU.  I would think anyone going for new camshafts would probably be prepared to get a optimised tune as well.

  3. From what I understand the aim of this new car is to increase everyday usability to make it more viable for the mass market.  

    I'm guessing it'll be pitched at something like a new version of the Elan M100.  Really nice fun chassis but not as hard core as the Elise or Exige.

    Pistons head article also says the price range will be from ~£50K to ~£100K.  So I'm guessing it have many many more options than Lotus normally come with.  Eg many different engine sizes, different suspension upgrades and body kits and areo options.

    Possibly a basic model will have a 4 pot engine and suspension optimised more for the road.  Top end having a forced induction V6 with fully adjustable Ohlins suspension and lots of carbon body panels and wings and spoilers for the track and lots of options in between???

  4. I don’t have the kit but from what I understand it’s not active.  It simply allows you to alter the damper settings using the touch screen installed inside the car.  It has 3 presets and each preset can be adjusted to your liking.  I believe the kit gives you full adjustment of the compression and rebound settings and is symmetrical across an axle, i.e. you set up the compression and rebound for the front wheels separately to the compression and rebound damping for the rear wheels.   You can’t do some weird setup whereby the left is different to the right.  The controller box is a roughly 6inch screen (diagonal) and maybe 4cm thick and can be installed where ever you want.  For the Evora the common place is in the glove box.  The are some servos or actuators on each damper and a bunch of wires connecting it all together.

  5. @Mattmahope I think maybe Dave Carr the owner of ES Motorsport has it on his Evora?  I don't think he's on this forum so might have to give him a call.  He does respond to emails but I find phone calls are are more responsive.

    The price for the suspension seems ok to me but the mechatronics kits feels like way too much money for what is quite a basic bit of electronics, maybe I'm missing something?  It might be difficult installing the kit but as far as I understand it the £4K is just for the kit, fitting is extra.

  6. hmm 8 years would have been iffy for me if they where brand new but used ... that would be a bit too old for me on something like an Evora.

    I don't know what the going rate for a set of wheels is but if they are official Lotus wheels and in good nick £450 sounds good to me?

    Regarding winter tyres vs new summer.   I'm a big advocate of running separate summer and winter tyres since switching over a few years ago.  But mine is a daily driver if you do limited miles and I guess with COVID most people are doing considerably less miles it might be hard to justify new winter tyres for this year.

  7. Sorry for delay, I only recently found time to take a look at the car.  The job was super easy in the end.

    The silver trim for the HVAC controls and gear leaver shroud all come off in one go.  It's just held in with trim clips so just some gentle leveraging with trim tools and the panel popped off and I could access the shift changing mech.  The opening was a bit cramped but I could access everything OK.  No need to take the whole centre console apart.

  8. Sounds like the mechanic doesn’t know what they are doing. Are they an official lotus garage?  If not maybe consider taking your car to different place. 

    The garage should be able to pull diagnostic information from the cars ECU showing the throttle pedal position, throttle body position, MAF readings etc and explain to you exactly why they are suspecting malfunctioning parts. 

    At idle the throttle body should be pretty much closed, can they show you if this correct or not.  Can they show you what the MAF readings are at idle and show how these values  are different from the expected values? 

    The throttle body position should move in correlation to the accelerator pedal. Can they show that the throttle body does not respond correctly to the accelerator pedal inputs. Can they show the ECU is sending the correct values to the throttle body?


    According to Deroure a new throttle body should cost about £1,200.  Are the import duties in your country so high as to push the value to £3700 ($5K)?

  9. Was the new engine new or reconditioned?  

    Have the issues started as soon as new engine was installed or was out working fine for a bit and then stopped working?

    Have your garage absolutely ruled out electrical issues. There are a ton of new sensors and wiring to plug in and get correct in a modern engine. 

    The info on the binnacle doesn’t make 100% sense. Eg engine is at ~2K rpm but all the shift lights are on.

    To me suggests something is not calibrated correctly or communicating correctly with the ECU.

    Im guessing you are using the factory ECU with the engine? Do the garage have access to the Lotus diagnostic software? 

    or failing that get a standard OBD reader and see what error codes are being produced. 


  10. Thanks I got a copy of the manual and had a read. 

    The adjustment needed is to the cross gate cable and you can do the adjustment at the shifter or the gear box end. 

    If I have understood correctly I take the ball socket of the gearbox wind the socket in or out one turn and try again. 

    I think that might be better than the shifter end as I think I can access the cable ends as is in the engine bay. I have an after market induction kit so there of a bit more space in the engine bay compared to standard. 

  11. How would I know weather adjustment is needed on the gearbox side or gear shifter side? 

    I’m reasonably certain the cross gate movement needs adjusting. As I said there is far too much movement allowed on the gear stick when moved to the left so that you go past the gates for 1st and 2nd. 

    I’ve read online here about adjustment available on the gear shifter mech to adjust this so I assumed it would be that, that needs adjusting. 

    Also I should note my car is an S1 car but I installed the new 4xx gear shifter mechanism and cables in my car recently so the issues are most likely due to that.  If it’s a simple fix that I can do I’d like to give it a go. 

  12. Yep temp on my NA Evora needs to be at least 1/3 up the scale before there is any real heat coming from the vents. 

    If you are just waiting for the first blip or two on the scale then the heaters don’t produce any heat at all. 

    interesting comments about getting the engine up to temp. Have I understood correctly thinking it’s better to start the engine and get moving using light load and low revs on the engine to build up heat quicker rather than sitting idling for a while to build up heat? 

  13. Engine must be up to temperature for sport mode to be engaged and fit it to give you full revs. 

    You can trigger the traction control and afterwards the sport mode will still be able to be selected (assuming engine temp is good).  There is no safety feature in terms of the car thinking the road is slippery so won’t let you engage sport mode. 

    Is the traction control light on all the time or just monetarily when accelerating too fast and you break traction? 

  14. I can’t help with what the cause might be. But if it does come to replacing the catalytic converters then for that price you should probably get an aftermarket system.  Many options out there with sports cats giving sounds and power boost while passing emissions tests. Or if you don’t need to worry about emissions then you could even go for straight through exhaust too.  You have options available from 2bular, Hangar, Larini, Komotec and possibly a few more. 

  15. I need to adjust the cross gate moment on the gear shifter mechanism as its currently very hard to find 1st and 2nd gear.  Currently there is too much movement so if move the stick to the left till the stop, I go past the gate for 1st and 2nd gears.  If bring the stick back in a tad so its not hard on the stop, the stick slides into 1st and 2nd no problems.  So I think I just need to adjust the mechanism a little bit to get this correct.

    Whats the easiest way to access the gear shifter mechanism?  Does the leather shroud just clip off with some trim tools? Or do I have disassemble the whole centre console?

  16. It's funny how the talk is all on the Merc 2nd driver seat even though the contract is signed and Toto stating they like to honour their agreements.  Rather than Merc's number 1 drive slot.   But both Merc and Hamilton would be crazy to go anywhere else so I guess its pretty much a done deal they just need to agree on how much?

    I think its highly likely Russell will get the 2022 contract for Merc and I can see Hamilton staying on for another year even if he wins 2021 WDC, I think he genuinely loves it and as long as he's getting regular podiums he'll stay in the sport.

    I'll feel sorry for Botas if there is isn't a good F1 seat for him in 2022.   I think he's a good solid driver and while not an exciting personality seems like a nice enough guy.


    Fingers crossed for Perez getting the Red Bull drive and hopefully he can get on top of the car and get good performance out of it.   There are a few good drivers in F1 that given a competitive car can achieve the odd podium here and there but rarely get given the opportunity to shine so fingers cross for Perez next year.

  17. Yes sure down the main straight you might be faster at Bedford but the corners felt like they were taken at slower speed compared to Silverstone.  Which as noob I was more comfortable with, may not apply to everyone.


  18. I can recommend Bedford and Donnighton for a novice.   Silverstone is fine too as it has massive run offs but the speeds are higher so a bit more scary at first.

    Bedford is exceptionally good for a novice, as said lots of run offs and well sighted corners and the speeds are generally lower.
