    VF Tuner for the Lotus Emira

    I do not understand how people are seeing what I posted as "disparaging". none of what I said was derogatory whatsoever. Nowhere in my entire post did I say anything inherently bad or faulty about the product. But is explaining how it works now considered disparaging? On the contrary SEVERAL...

    I will repost and explain here. It is not surprising if it did get deleted. Some people really don't like that level of information being made public.

    Any JB4 regrets? Issues? additional thoughts?

    it would be very important to ensure which is which (i4 vs v6) as I'd bet majority of people with issues are v6 folks.

    JB4 Map 4 with Draggy Pro Run!

    It is no issue of the fuel system components at all. It is rather an issue of the ECU being unable to correct for the big gdifference in fuel demand on fuels with higher ethanol content. Same exact wording on all cars.

    VF Tuner - Upgraded Supercharger Lid

    the highest height is 100mm. It fits no issue. We are working on several products, and once our stock ECU tuning is released we will have flex fuel as well.

    VF Tuner - Upgraded Supercharger Lid

    Yes it should help, although I can't *confirm* how much it will on the JB4, as we don't have one. And the JB4 works by reducing load and leaning out fuel by modifying sensor signals. So it can only reduce heat by so much if the engine is running leaner. It is going to work a lot better when we...

    zero chance of that happening, also that's quite likely to increase the price beyond what makes sense for the part.

    any mod can potentially void your warranty but ultimately it is up to your individual dealership. We made our sales and tech guy aware of everything we are doing to our Emira and they are cheering us on. We sent ours in for a warranty claim (total power steering failure) they fixed it no...

    STOCK lid weight is 6.5lbs We are expecting our lid weight to come in under 5lbs. so, minimal weight savings.

    VF Tuner - Upgraded Supercharger Lid

    We have not tested weight yet, but I am quite confident there will be weight savings, the stock lid is surprisingly heavy. I'll get the lid weight in a moment. Also I will post the final design images here later today, and pricing if anyone wants to pre-order. your pre-order will be fully...

    carbon fiber lid we are not considering at this time, due to so many heat cycles we can't guarantee it would last forever without any cracking around the bolt holes. Second with that would be..cracking around the bolt holes over time., and the oil exposure. finally, cost. A custom CF piece like...

    A minimum of 7 horsepower? That's a wash. We are looking to maximize what can be done compared to the stock lid.

    Emira JB4 Tuning Now Available for I4 & V6 Cars!

    rather than running crazy long wires just to get the CAN data, just tap into the 2 CAN wires right off the ECU would likely be 10x easier. Just a thought.
