Yes, it has some more potential. But we Europeans prefer a safe(r) tune We have tuned the combustion engine and 'patched' the electric motor to have some more torque. Price is 890?, 4h job. Same ecu as the 3cyl from BMW/Mini. Just harder To reach!

And how do we Americans get access to this tune, and what happens when the engine blows up.....what do you mean by safer tune, what the tolerance level we are talking about?

I have a feeling the electric upgrade is useless. The stock engine has too much power already. I actually have to go light on the 'gas' when I'm in electric only mode. With more power coming from the rear wheels, it's going to be even less effective.
Maybe it will help with top speed. I'm wondering if a tighter suspension would help keep the front wheels down. |

well, we noticed that petrol cars @ bmw don't break warranty so easily.
My M4 is tuned as well and went in for warranty works, they haven't noticed anything... Quote:

Ok, ours had different suspension, but I do not believe the i8 is overpowered

Could you run an experiment on the upgraded i8 and see if you can get a better 0-60 than a stock i8 while only on e-drive? If you succeed, I want to know why. Was it because of improved suspension? PS: I'm actually not an expert in this area. So, feel free to correct me if I'm incorrect about how I understand things. |

Does this tune blow the warranty?
I suspect the answer to the question requires both engineering and legal knowledge. I have the latter but not the former. Anyone venturing an opinion without both may tread where no man dare. So I will: If the engines have been stressed beyond their factory-set tolerances, and one of them fails, I'm pretty sure BMW will try to find out why. So, unless the i8 is quickly detuned before BMW comes on the scene, I'd say the warranty is toast. (I base this opinion on the fact that when my portable charger plug got stuck, BMW sent factory people out and studied the problem at my dealership. They were intensely interested in knowing why the plug assembly failed. And they took apart the car underneath and replaced a controller embedded in the batteries.)

that's why I called it a stage 1 tune, here in europe that means it's a 'safe' tune.

I'm wondering if a rigged e-motor would also have increased regen. Any electrical engineers out there? Someone would really need to know what they're doing, though. Wouldn't want to start a fire because too much current is drawn through the wires. |

As a supplier or aftermarket provider, you can obtain some of the specs of what the OEM still considers safe. Especially, if the same engine or component is used in another series production vehicle to higher specs. Like that e-motor in the i3. The American aftermarket industry has been living off this fact for decades. That's how you can easily buy a Chevrolet crate motor with 572 ci (based on a stock 454) that puts out 1000 hp. All warranties are off at that point, of course. ;-) |
