Emira JB4 Tuning Now Available for I4 & V6 Cars!

[675430VME]

Exactly.

I have nothing against this type of development for our cars (quite the opposite) but people really need to go in with their eyes open.

The thought that you could do whatever you want and then if your car blows up just reverse it, pretend it never happened, take it to the dealer and it’ll be covered is naive to say the least.

Especially if you post it on a public forum.
Trust me. Lotus and your dealer know exactly who you are and what you’ve done to your car.

If you’re going to do this, you need to have the attitude that some owners clearly have - if it blows up it’s on me.
I’ll wear the cost and I’m happy to take the risk.

If you’re not prepared to have that attitude, think again.
Or at least wait until the warranty is over.

My senior service advisor at my local dealer suggested I go back and do an injector test before I install my JB4. I will follow his advice just to be safe as there are at least 4 cars waiting for their injectors warranty claims. There is a total of 50ish Emira locally with a few that already got their injectors replaced, a 10% failure rate is quite high imo. And if it fails again after I installed my JB4, I don't mind paying out of my pocket because I am aware of the risk involved.

Do they know what is causing the Injectors to fail?

 

[PatrickJS]

Where’s all the info on the injector issue?

 

[BobbyG]

I have my Emira scheduled for 1,000 mile service week and I will certainly inquire about the injector issue.

News to me

I was told by a very reliable source that part/component quality in some areas of the Emira are not as good vs, the Evora.

O2 sensors being one example.

Maybe injectors as well???

I would hope any tuner, including piggyback developers, would measure injector flow rates....increase boost, increases air which in turn increases the need for more fuel.
Not enough fuel causes lean conditions and eventually problems including the fuel pump, quite linear...but you guys prolly know this anyway.

And dealing with my local lotus dealer for a simple tire warranty, there's no way they won't recover boost logs to bounce any warranty claims.....I've lost trust in my lotus dealership and by extension, hethel.

There's not a "quality" difference, just a supplier difference. Some people seem to believe that the country of origin is relevant to parts quality, which is a strange position to take in 2025.

Understood Porter.

How does a piggyback add more fuel with only two connections / overrides. Think this is what VF tuner is stating. The Toyota ECU may not have stored conditional maps to address all the conditions that the overrides introduces...

No we do not. All we know there might be a batch of defective injectors from factory and aggressive driving or engine related modification will be more likely for it to fail.

Our experience in our local dealership is quite the opposite, they are doing everything they can to keep us on the loop and how not to get rejected for warranty claims, but once if the car is connected to Hethel and they find out any supporting data it is out of their hands.

A constructive recommendation for the Forum's website developer...

There’s so much unnecessary confusion generated by post messages when authors don’t identity the engine configuration they’re referring to. There's hardly any relationship of powertrain issues emanating from i4 vs V6 and, in fewer instances, V6 manual vs auto. It would be ideal and more practical to include the Emira configuration as part of each member's signature section (upper left corner of each post), absent which, particularly when addressing powertrain matters, the alternative is tfor each author to repeatidly identify their own powertrain/transmission in each post.

That's cool but I'm pretty sure every dealership will tell you how not to get claims rejected....it'll be a resounding " don't move away from oem"

I can't tell you online but they do a lot more that, if you know what I mean.

I know what you mean.....and I've had that relationship with my bmw dealership but I'm not there with my local lotus service center

 

[675430VME]

Btw, I am not sure if this is the same practice in the states or different from China, but Lotus China encourages DIY jobs at the dealership. You can bring your own parts to you local dealer and its mechanics will help and guide you through the whole process, sometimes even change the parts for you if you can't get it right, all free of charge. We are able to get a lot of "info" in the process as well.

I don't think this ever happens in the US

I Also do not find the case to be similar with Florida dealerships, but actually, it has been been my experience with other car brands in Portugal where dealers have been constructively helpful with installing aftermarket parts and helpful in keeping manufacturers to honor their warranty coverages.

In the bullshit safe. Anyone know the passcode?

Bobby. And he was told by someone that told him by someone that knew someone that worked for BMW.
