Still waiting for my G4 alpha 6-speed manual 335i

Terry did not leave me.



If shipped with 15 ohms would be great

All N54 powered cars have an electrical motor coupled with the flywheel to help increase torque at low rpm while also saving gas. The lower ohm resisters allow the "electric assist" motor to pull more amps, therefor increasing power output. The only downside is increased chance of the electrical assist motor failing, which is around $7,000 to replace if you go to the dealership.

Did you know these were hybrid gas/electric cars? They also have regenerative braking.

Ur kidding right? Regenerative Braking with the n54 motor hmmm, i didnt know there was an electric motor lol first time i hear this. I'm smelling bull**** :P

You have a good nose. The lower ohm resistors allow for a higher cycle duty of the turbo wastegates to be hit. This means you are also beginning to remove a safety factor.

Basically, lower ohm = potential for more boost.

Basicly gives you more boost but drasticly reduce turbos life.

The autotune isn't active yet in alpha. Right now it's just fixed maps and actually they don't have any taper in them at the moment for extreme cold or hot weather. But that is on the to-do list.

During very cold weather we may need to reduce boost for fuel purposes but the idea is to have the system monitor knock activity and also air/fuel and it will only reduce power if one or both are getting sketchy.

18 ohm by default. 15 ohm by special request.

I am reading the JB4 info, and I see that there are two pump gas maps (91 and 93 octane), a custom map, a conservative race gas map and a progressive meth map.

I am assuming the best way to target a specific boost target is to use the custom map and dial in about 2psi taper to redline?

also on the gauge options, 2/7, what is "avg retard"?

For the moment I'd suggest say map 2 for a bolt on car/93 octane off meth, and the progressive meth map with an additive of 40 on pump + meth.

Average retard is sort of like the aggression rating in the procede. The lower you are the closer you are to a maxed out timing curve (e.g. car can take more boost).
