Emira JB4 Tuning Now Available for I4 & V6 Cars!

[mr.suntorytime]

I thought meth was bad for you. In any case, I'm listening.

Is there a 100 octane map for the v6 or does the car explode at that point? Also interestingly the v6 dyno seems more sensitive to octane rating than the i4.

There is one installed on my test unit.
It has not been tested, so id likely need to collect AFR data and send back to burger.

You sir are a go all the way kind of guy. Nice work!

 

[seriously]

oh my... having this kind of stuff be a simple pluggable upgrade is seriously challenging my resolve to hold off on any more mods.

You and me both! I assumed this would be very expensive, custom and a general headache. It sounds like that might not be the case here.

the only thing that gets expensive is the gas prices now lol.

 

[Sjobing]

Have anyone seende any AFR readings when running this module?

Anyone know how big the injectors are and what kind of dutycycle they runs originally and arter you plug inn this module?

 

[crestima]

the v6 cars run very rich. this leans it out along with some other tweaks.

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.

If, for instance, you had it set it to the 93 map and kept the OBDII plug disconnected, will it maintain the 93 map in memory or will it default to the lowest map?

whatever the last selected map was used will be booted until you swap maps.

It does not default to stock on shutdown.

(the OBDII plug does not change how the JB4 works. its a monitoring tool for checking vitals for tunes.)

I am very suspicious. How can jb4 achieve so much better results than Jubu custom ECU results? JUBU tune is $$$ with many hardware parts for even 460HP - thats 460 at crank, probably 415HP at wheel.

Wooooow

 

[TurboTambo]

Still think there's way more to go on the turbo with this JB4.

Two key takeaways:
1) All of the conversation on whether the install is a simple DIY or not was addressed (it's not, given access limitations, even on a lift and coming from the developer!).
2) This is Lotus' worst nightmare, out of the box the i4 was confirmed as the higher HP platform when comparing base stock runs.

I think the install on the v6 is going to be way easier than the i4. Yes the i4 makes a lot of power.

Great point, his install comments were specific to the i4.

After viewing the video , this is how I see things for my V6.

I do not track my car.
I have intake + 3rd cat delete + open valve.

I am going to use 93 octane all the time on map1. (8-9 PSI ) Good for 420-430whp. +50-60hp compare to stock.

The map2 ( 10 PSI - 450-460 whp ) is for special occasion only for short period of time. +80-90HP compare to stock and big torque gain either.

I think that if somebody abuse the car or track the car on map2 it could become a problem for putting to much stress and heat on the engine and transmission.

Overall for a street tuner I think this JB4 is a good compromise for an affordable price. But for more serious usage like track day I think the Jubu or Komotec solutions/approach are more appropriate for those application.

@mr.suntorytime — they have revealed the secret to how the Tillets hold you in the seat so well with low bolsters.

 

[mr.suntorytime]

2 plugs both are accessible from top of engine with just the two covers removed.
takes less than a minute to plug in the unit.

*However to install the unit it may take more time depending on where and how you plan to secure it to the car.
should take about 15min to install with the bracket i make, and plug everything in.

Are you going to sell that bracket and show us some pictures of it ?

I was thinking something similar. @GRP Do you think the 93 map is safe on track? Not like a track junkie but just the occasionally track day
