Emira JB4 Tuning Now Available for I4 & V6 Cars!

[675430VME]

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 ?

I have known more than 10 cars that got injector replaced by the dealers. One guy got rejected for injector warranty replacement because he had a BMC and a generic piggyback. I am still going to install a JB4 because I don't care paying out of my pocket if that happens.

How much are the injectors?

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..

I will place it over the battery compartment, elevated with 2 “runners” so it does not get affected by any minor water that enters through the driver side drain hole. There is very minor water entry anyways…….

Alright, so after a way longer than I'd like to admit fight with getting the sensor clips to release (don''t want to break them!), I successfully installed the JB4 this morning. I have a bracket coming so I actually just ran the actual unit in the trunk with the wire sitting on top of the trunk seal, and will probably leave it this way with the engine covers off until the bracket gets delivered.

I am a degenerate and immediately went to the 93 map. The power is very noticeable, especially in the mid range. I would say the 3-4 shifts felt like the car built speed like my 991.2 GTS did. I did about a 10 minute test drive loop before reporting back, but results certainly as advertised.

While "in Mexico," I had previously taken the car up to around 140 mph before the tune — and it definitely took some time, especially trying to keep pace with an STO, a GT3, and a few other high-horsepower cars. After the tune, the most telling part of the experience was how effortlessly it pulled from 120 to 130 mph in the 3rd to 4th gear shift — completely drama-free. I used to joke that in my 911, that shift took you from “just a ticket” to “going to jail,” and without question, this car now gives off that same energy.

Out of curiosity, I used some assumptions to run some chatgpt calcs on power to weight ratio between these cars (and our Taycan GTS) for comparison:

** Assumptions made on the WHP being slightly elevated on the Emira as I have an eventuri intake and titanium exhaust installed/milltek controller installed** I also was catless and custom tuned on the 911. **

I originally picked up the Emira as a "stop-gap" car — something fun to drive while I worked toward an F8 or 296. But over the past couple of months, I’ve had this growing feeling that with the right modifications — coilovers, wheels, and the tune — the Emira offers a uniquely compelling blend of performance, packaging, and driving experience.


Long story short: if you’re on the fence about this tune, it should be a no-brainer. It completely transforms the car.
