Emira JB4 Tuning Now Available for I4 & V6 Cars!

[crestima]

Verily, this chariot doth move with most noble grace—steady as the stars in heaven, obedient to the master’s will. This past sennight, I did traverse the winding paths of yon mighty canyon, where the steed’s strength was ample, though its excess unneeded. Yet lo! That deep-throated power at the apex—'twas a boon most welcome, a whisper of might beneath mine hand. Nay, it is no tempestuous beast, no charger driven by furious winds; it hath not the reckless spirit of a turbo-born steed, whose breath is the wild gusts of high boost. Rather, it doth wield its force with measured dignity, a knight upon the road, steadfast and true.

Impressive. Seems like Mr. Shakespeare preferred the V6 over the i4.

100%!
my car was the test car so the tune was for my car specifically. you would run the obd temporarily in order to ensure your engine will act in a similar manner to mine. if not then tune will be adjusted.

Honestly i think it was better on the 91 map. since its technically running leaner.

you will be fine. you could remove the prefilter on yours so you can get better flow.

There is no 93 around me. Just can’t be bothered with mixing E fuels.

Nice, I have a Macan with Cobb tune.

Lol me too.

How does it feel on the street? Any driving impressions?

For the V6, both 91 and 93 feel quicker with more low end torque, though I haven't done any timed runs so I can't say exactly how much quicker or the real difference between the two maps. They both run very smoothly right out of the box, without the OBD connection and no mods.

Coming from an Exige S300 with a power to weight ratio of 6,66lbs / hp , the Emira needed more punch for me since the beginning.

At 480 crank hp on map2 I should get that exact same power to weight ratio so I should finally feel back home.

+80-90HP is a very considerable gain and it should be easily noticeable by the driver’s butt dyno without a doubt.

If Greg have started shipping the JB4 yesterday that means he must have installed his own JB4 unit onto his demo car.

I wonder what are his first tought.

More torque is exactly what the car needs and what I've wanted. Now I'm just watching and waiting to see how it goes with everyone who's ordering this.

Ditto. Definitely want more power and this seems like the "easy" button to do so. Almost sounds too good to be true. And you know what they say about "too good to be true"
My finger has been hovering over the "order" button from the day this thread started

 

[Rupes]

Fully agree. The claim that there's a magic torque limit for this motor at 500 Nm (369 lb/ft) is a curious one, and doesn't seem to match the experiences of any of the other automotive constituencies that tune the 2GR-FE, such as the MR2 community. They've also been doing it longer than the Lotus community and are much larger.

Jubu's specific claim is "The torque must not exceed 500 NM (+/-) with standard pistons. Otherwise the already known piston web fractures may occur."

I have yet to see this corroborated by anyone, anywhere. I'd love to be proven wrong on that, so if anyone has any documentation or can point me toward an independent claim on this, I'd appreciate it.

Not sure what is real or not, but my understanding was the transmission was the source of concern with a tune like this, not the motor.

I think in the back of my mind I would always worry a bit on those high RPM gear changes using the 93 map.

I've seen that claim often as well, and that's more understandable, though Jubu also seems to say that with an upgraded clutch and flywheel the problem is lessened - which makes no sense to me because that's not the gearbox. If anything, an upgraded clutch should cause more stress, not less.

As much as I wanted to pull one from the first shipment for our shop car I didnt because we have so many guys anxiously waiting on these. They were only able to get 10 V6 kits in the first batch to us. They are building them out as fast as possible and should have more coming late this week/early next. So they will be shipping out in waves weekly, in the order received.

Have they been taken off your website then, I couldn’t see them? What price are they?

Nope, they are on the front page.
