Emira JB4 Tuning Now Available for I4 & V6 Cars!

Same here.

He must have placed his order directly from burger 🍔 instead of GRP.

Better thing come to those who wait they said.

Greg got the first like 20 or so V6 from Burger I think?
 
Alright so I’ve test fit the installation and figuring out wiring routing, bracket mounting etc. I’ll have an installation tutorial up in the next two days because now I need to dismount everything to take video/photos etc.

As for the drive, well I’ve only driven in Map 1 for 91 Octane for 25 minutes. It’s worth it — the power and torque are instantly there on some back to back 2nd through 3rd gear pulls. Where the stock torque makes it feel like you’re not really pulling anymore, even the map 1 keeps you pushed against your seat. Map 2 must be wild, look forward to more testing. Power and torque delivery is nice and smooth and I experienced no hiccups anywhere.

More later as things progress.

Thank you KitKat for putting it in words that people can understand.

It’s so wild map1 vs stock and map2 vs map1

He got +or- 20 last week and he’s hoping to get another 10-20 this week as a second batch.

Burger are making those kit by hand one by one. That’s what he wrote on YouTube into the comments below the video.

I ordered on 5/6 I hope to get mine soon.
I ordered on that same day and we just missed the first batch, but Greg mentioned that depending on the amount to be received from Berger, we should be on this next one.
 
Looking forward to some draggy runs from you all
Here's a quarter mile baseline ran twice and very consistent. Eventuri Intake, GRP 3rd Cat Delete, Miltek Controller set to full open. Disappointing times but makes sense because this car is slower than my Evora 400. It has the 435 tune on it and traps 112-113. Ran this twice and same results. Not launching the car really just 3500RPM or so. Curious to see what other stock runs look like. Ill be putting the JB4 on now and doing the same runs in the same spot.

Good baselines! I think you need to be a bit abusive to get really good launches on the manual. Maybe the v6 will be as fast as the i4 now! lol, just kidding. I think overall power at speed is more important than fast launches anyways.

Thanks @Coreyalert3. It's fantastic to have some data with a common setup (Milltek VC, 3rd Cat Delete, + Intake). Those numbers looks like what I'd expect without an all out launch from my experience. With a JB4 Map2 tune (assuming it's really pushing another ~90whp), I would expect that 1/4 mile to drop closer to the 12 sec mark. Let's see!

Yeah not worth the abuse. Not going for records just good consistent data. No doubt the i4 is a faster car the trans really holds the V6 back but I still really enjoy it such a fun car to beat around in.

I'm expecting to see a trap speed around 114 or so if the 90whp gain is accurate. Time will tell! I'm about to start installing the JB4.
 
At first didn't really notice much of a difference on Map 1 but once I did a pull I could feel the top end gains. Trapped 3 mph better so 110mph vs 107. Was my worst launch of the runs so no time improvement but definitely can run faster as every time I'm bogging down bad. I'm on the Cup2 tires as well so they need even more revs to really hook and go.

I switched to the 93 Oct tune on the way back and could see an even bigger difference and I'll try to get back out soon. I'm actually battling the Flu or something at the moment and really tried to do this between waves of feeling terrible.

I did take a data log of this run too

Great work and thank you for sharing your log! Would you happen to know the source for the Y axis on the left of the graph? I'm interpreting that as AFR scale looking at the behaviors.

Is that something that can be user selectable?
 

here is a run i did a few days ago on the 93 map. think its about 4sec 7-60mph rolling start.
i didnt hit redline so its not ideal. the car is lighter with tillett b10's and antigrav battery.
