Emira JB4 Tuning Now Available for I4 & V6 Cars!

[Barcino2012]

I'm wondering how they're routing the cable from the TMAP to the MAF that the instructions show just hanging across the engine for the V6. Also this is obviously tuned for the factory airbox. I would like to know if the Eventuri airbox would require a custom tune map, since it's airflow and IAT is different from the stock airbox, or is this something their unit is able to adjust to the same way the factory ECU can.

Yes, that seems to be the only ways they can access the CanBus, via OBDII, and that is how it has access to more parameters……I guess we have to get the drill out, given how aggressive the tune is, the more info the system has, the better……


The JB4 tuner for the Lotus Emira utilizes CANbus integration via the OBDII port to access and manipulate a wide range of vehicle parameters, offering enhanced tuning capabilities and performance features.

Is CANbus Integration Only Available Through the OBDII Port?


Yes, for the JB4 system, CANbus integration is achieved exclusively through the OBDII port. This connection allows the tuner to communicate with various vehicle systems, enabling features such as:

• Reading and clearing fault codes
• Monitoring and recording up to 40 engine parameters in real-time
• Adjusting boost by gear settings
• Accessing custom tuning maps for different fuel types

From what I have read, the V6 test car had a blue grp drop in air filter + 3rd cat delete. Same for me but K&N instead.
So both map have been created with that particular setup but it has been said that it wont be a problem to operate a eventuri intake with an exhaust for example. May be it wont extract the most out of them but wont hurt power for sure.

Factory airbox with upgraded element yes.

It was said by the team that it will auto tune with the obd connection active. I don’t know how much or little it will add to the overall tune.

That being said. Phoning them when it’s all connected and doing a few pulls should result in a new tune from burg.

Actually I would expect the Eventuri to get more performance, as it increased the power and torque on mine after I installed it. I dynoed mine before and after, and I gained 16.5 hp and 15 ftlbs of torque. I drove with it installed for a couple of weeks before getting the dyno so the ECU had time to adjust.

Yeah that's what I was wondering, if sending them data logs would help to fine tune it for the Eventuri.

Yep, there will be some gains for sure. I’m hoping for more low end due to lower resistance and larger aperture.

There must be a way to route that cable into the engine bay without having to drill a new hole by using an already existing one…

I wont do that extra hole for sure..

If I route the OBDII cable temporary by the driver’s window thru the engine bay and drive the car a couple times like that to allow the Jb4 to get better accurate information about what is going on. Do those corrections are going to be saved ? Or if when you unplug the cable you just go back to where the map was created initially at first ?

When I tuned my previous car with Ecutek with data logs over the internet back and forth, I had to pay something like 250$ for such a service with ft86speedfactory. Does burger motorsports is going to offer such a service to anybody asking for custom tune ?

Before I bough the box, I actually emailed with Terry Burger asking if they make a custom tune that would stay at the 500NM, juhu’s concern, while maximizing hp……he did not acknowledge that agreed with that concern in general, but said, yeah we can look into that, so maybe they eventually offer additional maps and one for a 500 NM max, this was my wish graphic I sent him

Just for some clarification, the need for an OBDII constant connection to the JB4 module was addressed earlier in this thread by @mr.suntorytime whose Emira, I believe, was a test mule for the JB4. In his post of May 7th he said:

"the cable that needs to go from cabin to the engine bay is the OBD2 connection. not really needed to function, only really useful to log data for upgrades and to clear code on the ecu. i currently have mine disconnected."

This led me to place my JB4 order with only the $40.00 temporary cable to connect to my Laptop and program it to my desired map which, btw, I'm leaning towards the 93 octane map. I didn't opt for the bluetooth wireless smartphone dongle, not necessarily because of the extra $, or because I wanted to avoid routing an extra wire from the OBDII to the engine bay, rather it was because I'd simply rather decide once and for all on my preferred map, and then just leave the thing alone. If I come to regret it later on (which I doubt I will), I can always order the dongle separately and add it. I definitely understand the attraction to others of gathering performance data, switch mappings on the fly and working towards new customized maps etc which the OBDII connection and wireless bluetooth feature surely will facilitate, but that's not for me. In my case, no OBDII connection, no bluetooth dongle and once I select my preferred map, out comes the laptop connector too.

Greg think that Jubu are very conservative about the max torque limit the transmission can handle. They may have an interest to present thing that way to sell more parts. If you drive your car into the streets and do not beat the crap out of it for drag race or at the track on a regular basis I am pretty sure you will be just fine at 396 instead of 370. This is not something that I would be affraid of. If you are an extreme racers then probably yes better to limit the power for reliability and less stress purpose for better longevity.

It’s on the jb4 side. So same connection the cable uses.

Also Jubu wants you to buy all of their gear. There is plenty of evidence from many tuners that this mill can take up to 600hp with stock internals.

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