Here is a short video of my car’s acceleration. I was not on a flat road. I was going up hill, see the picture joined. The car is pushing strong for sure !

5th - 6th gear me too.

My friend had a 204 km/h trap speed on half mile drag race stock and with JB4 about 218 km/h. For those wondering if the car will heat soak on track with JB4 just start using map1 and if everything is fine I would switch to map2 and if after couple laps temps are going up you are just at a...

Good boy !

Look like this.

Does it goes like that ?

It is worth the assle so much. You just need a thin and long funnel to be able to drop the bottle before to fuel the car at the gas station. Mine claim to raise 4 point so 94-95 octane is going to be even better. I would not consider it safe the run map2 on 91-92. The tune is gonna be too...

No need to pass the cable under the dash trim or under the sill door panel, just route the cable between the center console and the driver’s seat.

Well said. I could not have said better. 7200-7400rpm - 460-470 whp and I am good for the moon !

To be honest I did not check or remember if the oem one had only 3 pins instead of 4 but if your pins struggle to make a good contact signal you can apply a tiny amount of special White grease specially designed for electronics connectors to try to help.

Similar here but not sure if the only log I have been able to record was on map1 or map2 because I still have to learn how to start and stop de log record software. I was expecting to have recorded 2 files for each map and found only one. Boost peak / spike up to 8.7 around 6K rpm and lower...

My friend had a similar problem. He had a bend pin on his MAF. Unplug your connectors and make sure you did not screw it up when you previously connected.

First ride of 2025 and with the JB4 the car is now alive like it should have been from the factory.

11-12 AFR at WOT & high RPM seem ok to me. Better to be on the rich side then lean. Into the Rotary world Steeve Kan was tuning our RX-7 at 9-10 even richer. At lower RPM during normal driving 14-15 is the target. I may be wrong so Payam could correct me. My mods are GRP cat delete - K&N...

I did my first test yesterday evening. I only have 91 gas here but I was also running agressive tune with my previous car by using good quality expensive octane booster like Amsoil - NOS or VP to reach a solid 93-95 octane level. I started with map1 and found the car already more nervous and...

I leave here some pictures of mine : Custom Steering wheel : ✅ - Rounded Top - Flat bottom - Perforated leather : handgrip - Alcantara fabric top & bottom - Silver center stripe and stitching Perfect match with my car.

I will check if we can monitorize the injectors duty cycle percentage with the JB4. We dont even know if they were pushing them at let say 75% oem and maybe let say 90%+ with the tune for example. I dont even know the size or our injectors, how many cc they have ?

Your bracket will be very welcome ! I really dont like how my JB4 is approximately holding in place on top of the airbox in diagonal. It dont make sense..

In that particular case, the 3rd cat delete with a milltek valve I think was the only mods done to his car and the dynojet sheet showed a +13 WHP.

Myself I saw a before & after dyno onto Lotus Emira Owner USA facebook page.

With the Jubu 460 kit, the SC pulley is even bigger to get less boost, lower engine bay temperature and putting less stress onto the engine. So that means without doing that it would be called a 475-480 kit in fact. Remember the JB4 test car had a GRP 3rd cat delete, It is a 13 whp right there...

Yours was pushing toward outside like the others I guess or pushing toward the inside like mine creating a bump ?

Does anybody knows how to adjust the rear bumper. I have a bad fitment on the passenger right side. ( see the pictures below ) The driver side is perfect. I removed the fender to have an acces to see how it was done behind but I do not understand what I need to do to release some pressure over...

I own a lotus since 2007, I bought parts from Greg for more then a decade for several several thousand dollars and never been worried what so ever but this is not the point here. The point is that Burger seem to fullfill people ordering from them directly faster probably because it is more...

Fingers crossed 🤞the second batch is starting to ship. Let the fun begin.

Wow you find the part fast. That is good news. Where did you find it and for 1200$-1300$us I guess ?

Same boat here. It could have been faster to place the order thru burger website. I think they may give the priority to those placing order directly from them. We saw someone here who placed his order after us and got it at the beginning of last week already. It shows how people was...
