Emira JB4 Tuning Now Available for I4 & V6 Cars!

In that particular case, the 3rd cat delete with a milltek valve I think was the only mods done to his car and the dynojet sheet showed a +13 WHP.View attachment 65383

Installed my JB4 today, initially programmed to Map1 (91 octane), took her out for a trial spin, but struggled to notice much of an hp increase at all. I then changed to Map2 (93 octane) and, wow, I immediately and most definitely felt the increase.

My Emira has a GRP High-flow Media (blue) filter, 3rd CAT delete and Miltek valve controller, which interestingly, I believe are the same mods of the V6 test car used in the Burger YouTube video. Also, I've been feeding my Emira 93 octane since the onset.

I'm not installing the OBDII connector because I'm not really in to checking, gathering and crunching performance data rather, I'm content with my own seat-of-the-pants experience, and a good one it is.

As for the risk/reward debate, with all due respect to the more conservative and perhaps wiser of you, for me, the added enjoyment of Map2 is worth the tradeoff in risking broken axles/motor, whateva...

This is good info.. I will not be doing it... but I will be coming down to see yours. Not sure I would do this until after my extended warranty is over, but maybe later down the road to feel like it's a new car again.. Right now I am super happy with the power I have as I really only cruise around anyway.. Def not tracking it, which I would be in a different camp if I were.. but love all the info from you guys for sure.

Just curious, how easy/hard is it to switch from the different maps?

Can you run the 93 map on 92 octane, or is there some pinging/problems that will arise other than maybe not getting the published HP gains?

Brackets will be completed this week and will be sent out in order as they were received.

Thank you everyone for your patience and trust as always!

For something like that, we'd like to see data logs on map 1 and map 2 to verify it's safe. Which means we you will need to install the OBD2 plug.

We're working on the Lotus again to find a better CANbus source in the rear that way you guys don't have to run the OBD2 to the front interior.

That’s my dyno, and the shop is also surprised that there was such a big gain just with opening the valve.

My JB4 comes tomorrow and I’ll be installing it and running it on map1 for a week or so before switching to map2 even though i have 93 and thats what’s in the car right now.

Once I feel comfortable and it seems like it’s running well I’ll get it to do a dyno at the same place under similar conditions hopefully, and see the comparison.

Unless I misread it, doesn't the OBD connection enable it to work with the ECU and make adjustments on-the-fly to your car? Obviously it's a hassle to run the connection, but you only have to do that once, and the benefit of live tuning as conditions change seems like it would be worth it.

crestima said:

Maybe a not-so-wild-guess, but wouldn't a source be found in one of the ECU (ECM in Lotus vocabulary) module's harness connectors ?

Yes, I'm working on removing the side guards and intake to reach that as we speak. ECU will have the CANbus wires but hard to locate which two exactly out of the hundred wires going to it without a dealer schematic lol. Sometimes it's easier to find it on an ABS unit, etc as those are usually a twisted pair bundle.

Will keep you guys in the loop!

When/if you do find a source, will current JB4 units need any additional connectors/modifications in order to be able to connect to it?
