I already have a dyno chart without the JB4 which was my last run. Here's the page on my project thread which shows the last dyno run with all the mods I have up to that point. https://www.emiraforum.com/threads/adding-lightness.4796/page-17 I got the all-clear from Burger that my data log...

I do it more as a service to the forum. I started doing this with the Eventuri when it first came out, because people were skeptical of the claims, so I got a dyno run to show on paper what I was experiencing. I knew it was adding power and torque, but it helped to have a number to show. This...

I wish we had 93 here, but we just don't. I'm glad you noticed the smoothness too. At first I thought it was my imagination, but the engine does run smoother with the JB4 tune.

I sent my log file to Burger last night, so as soon as he returns an all-ok or an update, I'll do a quick 100 mile run-around then get a dyno run. Hopefully sometime next week if they have a slot open at the dyno shop.

Glad you worked out something for you. I think the OBD connection makes a difference, as I just got back from driving around an hour and a half, testing different speeds and drive modes. On map1 91 octane, the car seems to be running smoother than it does stock. Outside air temp was 89F...

I wasn't able to drive it yesterday, but tonight I'm going to go out and record a data log, then send that to Burger. If all's well or they update the tune, I'll update and then do a hundred mile run, then take it to the dyno shop, hopefully next week if I can get a slot for a dyno run.

Put a towel on top of the Eventuri, and underneath the bracket mount location, so if you accidentally drop a bolt (or socket), you won't go through the ordeal of having to retrieve it from down in the engine bay. ALSO, VERY important... do NOT remove both of the original bracket screws at the...

The engine bay gets really hot, and that's just stock from the factory. Adding more power and performance isn't going to make it cooler. I noticed how hot it really gets when I was adding heat reflect material under the trunk, since it gets so hot in the trunk. I thought it was mostly from...

I don't even think this is journalism, more like opinionism which is ridiculously subjective. It's also almost fashionable in some circles nowadays, to poopoo the Emira as being not quite up to expectations like there is such a thing. It's a better, more finished and complete sports car than...

Finally got everything sorted out, and took my first drive this evening. Drove on Map0 to a Shell station, letting the car warm up to normal temp to make sure there weren't any issues or CEL's. Car is fine. Switched to Map1. I could immediately tell the difference as I left the Shell...

Well I got lucky and found the bolt. After removing the Eventuri I was able to see better. and it was sitting down in between two hoses, so I was able to retrieve it with a flexible magnet wand. I was finally able to get the bracket installed, but I'm pretty sure the socket that dropped went...

How did you pop the vent panel off? Is it just clipped in place?

So the bracket arrives, I go to install it, and it's a real PITA to try and get the bolts threaded in to hold the bracket. It's hot, I'm sweating, so naturally the first bolt and the socket on my ratchet slip out of my hand and fall down somewhere into the hell of the engine bay. So now I'm...

Payam addressed that on post #1050 on the previous page. He says it works but to be careful with it; not the exact same as actual race gas.

That doesn't have to be stated. I merchant cannot take money for a product or service, and not provide it but still keep the money. Was this Naples? Contact Lotus, contact the Attorney General for the city the dealer is in.

For those of you who have it installed, which app are you downloading? There's a free on and a paid one for iPhone.

Mine would be from that batch, but I can't complete the install until I receive the bracket, which is supposed to arrive Monday. Is yours a manual or auto, and did you connect the OBD cable?

Here's that same area in the picture with the white fuse box cover, but the cover is removed. You can see how much more room you have to get your hand behind the curved plastic piece, which is hiding that rubber plug.

I placed my order with @GRP and I already received the shipping notice, so it should be here pretty quick.

Lotus Excel cam cover.

Trying to get mine installed. I used your trick of feeding a stiff cable through the rubber grommet. I only had to pull the carpeted corner piece out, I didn't need to remove the back panel. The white panel on the right in this image, is the plastic fuse box cover. The white part is actually...

Did you reuse the old ones, or use new bolts and nuts? There IS a lock washer on them, yes? If there is and you're tightening them to spec, maybe you'll need to get race bolts and nuts that are drilled so you can safety wire them.

Glad you like it! I was pleasantly surprised at the difference as well. Which adapter are you referring to? You'll only encounter the gasket when you disassemble it to clean the filter.

What fitment issues were you referring to?

I'm way out in this distant place called Idaho. I know I know.... but we now have electricity and indoor toilets! ;)

@GRP @Payam@BMS I ordered my JB4 from GRP on June 1st. My wait is beginning to become slightly biblical. For 40 days and 40 nights I've waited, but no bueno. Any news?

This is a great video. I really enjoyed this one. Looks like the series is going to be epic.

This is the only image I could find from Goodwood so far. Not sure this is a street car though.

That's the particulate from the initial wear-in of a brand new engine. That was in the oil before I removed the filter, which also had particulate in it. This is why you change the oil after the first few hundred miles of a new engine, so that particulate isn't circulating in the engine. I...

I did an oil change right after the 1,000 mile break-in, and this is what came out of the engine. This is the drain pan I drained the oil into. Those flecks of metal you see aren't gold.

There has to be a display control module somewhere....

It's interesting that they changed the loom location for the 2025 model year. If you climb into the trunk and work from there, it's easier. You'll have to remove and reinstall the unit every time you clean the air filter.

Don't track a tire with a plug. If the tire heats up too much, the plug can blow out and you're toast. Is it a front tire or rear? A plug will be fine for normal street driving, but for extended "spirited" driving I wouldn't trust it. Get the plug so you can take the car to a tire place and...

Lotus didn't really shoot themselves in the foot, they were machine-gunned by covid, supply chain issues, Brexit, inflation and things they never imagined were in their future when they originally did their forecasts for costs and production. I still think it's a great car, but it's not enough...

Isn't this the same Evo who's Jethro trashed Lotus and the Emira when he was given a pre-production car to test drive at Anglesey, and compared it to a track prepared Porsche that just happened to be there that same day?

How easy was the access? Did you have to remove the underbody panel?

Soon as I get my unit I'll do a dyno run; same shop as my previous runs.
