BAS 86 Posted July 18, 2018 Report Share Posted July 18, 2018 I haven't picked up my car yet after the 1000km service+another issue I had, but they installed my exhaust button. Once I get it sometime next week I'll report on the sound (pops) + if it works on all modes. For now they sent me this: VID-20180718-WA0034.mp4 2 Quote Link to post Share on other sites

BAS 86 Posted July 28, 2018 Report Share Posted July 28, 2018 @AlphaZ Hi. The dealer needs to run the lotus software to "enable" the flap. A dealer visit is a must. Also, my dealer has confirmed to me that the exhaust button only works on normal mode. On sport and race mode, it is back to original ecu controlled even though the button is pressed. I'm collecting the car tomorrow and will see for myself. 1 Quote Link to post Share on other sites
Tex 217 Posted July 28, 2018 Author Report Share Posted July 28, 2018 Yes absolutely correct After button is installed you need the dealer to perform an ecu upgrade and the switch only opens valve in normal mode. Quote Link to post Share on other sites

Do you get the pops and bangs as with the 380’s ? Quote Link to post Share on other sites

However, there is definitely no pops and bangs that are noticeable. OEM exhaust switch as others have mentioned only works in normal mode (which is a shame, but better than nothing I guess).

GFWilliams 1,975 Posted August 4, 2018 Report Share Posted August 4, 2018 If you want it loud the whole time, just pull out the tube from the valve. It will default to loud mode. Quote Link to post Share on other sites
Tex 217 Posted August 4, 2018 Author Report Share Posted August 4, 2018 So would appear that Lotus have removed that sound even with the valve open. Shame as even at low speed the sound from the 380 Exhaust wasn’t deafening but did make a great noise which the 430 does not quite have. Having said that the Titanium Exhaust at higher revs is a real belter but not that track friendly unfortunately. Quote Link to post Share on other sites

Going back to the OP's post, I thought I might add a few things that went wrong on mine last few days. Am on a road trip: Surrey - Frankfurt - Prague - Frankfurt - Surrey On day 1, in a Belgium petrol station somewhere, the passenger door release failed. The lever does not work now, so the only way to get in and out is from the outside (with a bit of luck!) I'm guessing either the cable has disconnected, or the locking mechanism has malfunctioned somehow (the door pin looks really suspect). Once we figured out that we could manage with this issue for the time being, we set off... only to find that the rear window had essentially de-bonded from the bulkhead! How did I find out? It was fxxxing loud in the cabin. The plexi was rattling away, so had to find some duct tape at the next stop and do some DiY. Later on, somewhere in Germany on the way to Frankfurt, the rev limiter started to kick in at 4k rpm in every gear. This meant around 110mph in 6th, great.. with a bunch of derestricted roads ahead of me . Pulled over, restarted, and it went away. For some reason, the cruise control doesn't work when this happens as well. However, seeing as it was a great day, this limiter problem came back again a short while later. This time, restarting couldn't cure it. So nursed it to Frankfurt and booked in a visit to the local service centre the next morning. Diagnosis showed that apparently it was a safety feature kicking in when over-heating. To be fair, temperature was around 35C, with road temperature around 46C. Called my local dealer back home, they've never heard of this. Day 2, just before the Czech border, the MIL light comes on. Stays on for the rest of the day to Prague. etc etc etc.... On the bright side, once the temperature dropped, the car has been fine. Engine and gearbox have done fine on the autobahn, let's see what my dealer says when I take the car in for everything to be checked! 1 Quote Link to post Share on other sites
Tex 217 Posted August 11, 2018 Author Report Share Posted August 11, 2018 Sorry to hear of your issues but hopefully won’t detract too much from your road trip, but one thing you don’t want is any more noise in the cabin !! No consolation but was in Venice last week and on trip from Airport saw a Ferrari 488 broken down due to the heat. Apparently the high humidity and 38c had triggered limp mode, which was a dealer reset. Quote Link to post Share on other sites
Tex 217 Posted August 11, 2018 Author Report Share Posted August 11, 2018 Quick update. Roof is back squeaking, but expect this to be an ongoing issue, you fix it and then 2 weeks later it’s back, probably need to obtain the security hex tool to do my own adjustments. The Nitrons have loosened up nicely although when you hit a hole they absorb it brilliantly but seem to make a very quiet woosh sound, like air suspension, not a problem though. Upgrade to the boot release appears to have worked. Everything else all good. Chancing my arm by booking track day at Donnington week on Monday, with the decibel limit, but want to see how Car goes on the GP circuit. May be a case of short shifting in the morning in case !!! 2 Quote Link to post Share on other sites

Popular Post AlphaZ 8 Posted August 11, 2018 Popular Post Report Share Posted August 11, 2018 Hi, Finally got time to record the sound... Cheers 3 Quote Link to post Share on other sites
Tex 217 Posted August 12, 2018 Author Report Share Posted August 12, 2018 Where did you position the microphone as has picked up the noise well, a deep base sound. On the point of the exhaust pops and crackles on deceleration, I couldn’t tell if yours makes the same noise you get from the 380’s. They make a right row when lifting off with the valve open. The video with an Elise below is a similar sound to the 380’s on deceleration. It would be good to know as the Cup 430’s and Exige GT 430’s with the retro fitted exhaust switch do not appear to have this feature even when the valve is open. Sound is still superb though !!!

Hit 107db on the international pit straight at Silverstone in my old 380 back in March and soon had to bend over for the noise police !!! It is peculiar with Donnington though, as Airport is next door and I don’t think the planes would pass the dB test and in addition next Tuesday they have a 118db Track day at a vastly inflated price Still looking forward to a go on the Gp circuit even if there needs to be a bit of short shifting, although i think my 430 should be quicker than my 380 at lower revs with the extra torque 1 Quote Link to post Share on other sites
Tex 217 Posted August 17, 2018 Author Report Share Posted August 17, 2018 In readiness for first track day in 430 and my first experience of 3 way Nitrons I thought I would try some different settings on the road today, I didn’t want to remove the wheels so started just with the high and low speed compression adjustmentS. No problems with the fronts but the rear nearside is a [email protected]@@@ to get to when your hands are large !!! Nevertheless went fully soft and then dialled back in to ascertain best road use setting. Fronts seemed best at being a little stiffer than the rears over faster roads. What I did notice was Car was not set up from new with the factory settings of Front Low Speed 4 & High Speed 10 Rear LS 3 & HS 12 Quote Link to post Share on other sites
