Pedal Commander or Sprint Booster for Lotus Emira Turbo I4

[Rayjoedef]

Curious if anyone is familiar with the accelerator pedal on the Emira. Is it the same as the Evora, Elise, Exige? I've put the sprint booster in many of my turbo cars and its a night and day difference in throttle sensitivity.

Some guys in my group use it for theft prevention.
Set the value to 0.
Even if it's started, they can't drive away with no gas pedal input.

I'm looking to see if there's any hardware/software available that's compatible with the Emira I4 to increase throttle sensitivity.

Doesn't seem like a bad mod for the price. I'm interested.

Website for Sprint Booster lists only Elise and Exige-no Emira.
Sounds like a nice addon though, and would consider primarily for theft/valet use if/when available.

Gain sensitivity, but lose control and modulation of throttle. I don't rate these 'gimmicks' at all.
All they do is increase throttle input compared to pedal input. You apply 10% pedal travel, and it increases it to 20% throttle. You feel like it's more sensitive, but you just have less control. 100% pedal remains 100% throttle, so you don't actually gain anything at the top end of throttle application. What's more, your brain recalibrates to the new pedal positions over time and you lose the 'sensitivity' you thought you gained.
Honestly, save your money and buy a product that actually improves performance.

Nobody mentioned increasing top end with this software. As you put it, if I can get 20% throttle with 10% pedal input by opening the tb quicker, we'll I'm good with that. It's a small, inexpensive plug and play that's made me pretty happy with my other turbo cars.. .of course it does not replace tune or full exhaust.

Check out some reviews out there, pretty good responses

Thanks for the input

This is an incorrect take on this. When you are using a car without pedal commander and an electronic controlled throttle the driver demand tables are indicating the throttle body opening response. The driver demand tables take the percentage of throttle application and translate it to what percentage the throttle body should open, fuel application etc . However this programming takes in more than throttle, it’s what mode you’re in and whatever else they've programmed into to ecu to basically get it to pass emissions and have a different feel in the different drive settings.

So although you’re correct it adjust the signal, the ecu is still modulating that number based on the other factors being applied to the tables. Saying you're losing sensitivity is like saying you shouldn’t switch drive modes because they feel different and you’d be only used to one. You’re also incorrect that 100 percent application of the throttle is 100 percent in the demand table. It’s not that simple, it may not be 100 percent immediately to account for someone accidentally flooring it. That 100 percent activation can change over modes.

Further, the take is silly because every sports car that is not electronically controlled has a 1:1 ratio of throttle application to throttle body opening percentage. (As far as I know, I guess there could be some that are still modulating with mechanical in a different way but whatever). All you are doing with pedal commander is bringing the car more in line with that type of experience. If you can’t handle that, it’s a driver issue not a pedal commander issue.

Pedal commander has like 36 different setting modes. Those setting modes are basically allowing for more control over your throttle response than the three you have in the Emira. It would be like taking the tour/sport/track and giving you an additional 8 sub settings for each. It also has an eco mode option too.

I have a C7 corvette, my wife has the Emira, both of us were shocked with the Corvette when we added pedal commander. We don’t even use the sport+ setting because of how much better sport is. It is also a much easier drive experience because when you flatten the curve of the demand table you have a better idea of when power is going to be applied. You’re not guessing what point of the throttle the car will be applying real power. I’ve been hoping they’ll come out with one for the Emira, since we can’t get tunes where I live its the easiest way to change the demand tables without actually changing them and not being able to pass emissions.

I've sent the connectors to sprint booster and burger to see if they have compatible hardware and software. I believe a throttle controller coupled with a piggy back (I do this with all my cars) absolutely transforms the car with little to no warranty worry....imo

Nice! That’s all that we really can do in Colorado unless someone goes through the effort of CARB approval. There is one supercharger I could get for the c7 that has is but otherwise you can’t change the ECU. During emissions they run the check sum number on the ECU and the current flash has to match that number. If it doesn’t it has to have CARB approval certification and match that documentation.

But I agree it’s a very big transformation especially if the car is setup to be pretty muted in normal drive modes.
