Hello,
is it possible to tune for quicker reving an the ME7.5... is there a chance to change some paramater i can tune for quicker throttle response.
Have a nice day
Martin

Run it on high octane fuel and get the timing bang on, free flowing intake and exhaust, other than that, lightening and balancing.

This makes 1% of difference. The 99% is flywheel weight and making sure LSD is not too aggressive in ECU. |

Hello,
i find some other parts:
Throttle Response improve
There are a bunch of delays stacking there
1) ME7 slow torque path (most of it)
2) throttle plate actuator/servo control (probably a few ms)
3) throttle plate angle sensor sampling (should be less than 10 ms, unless the ADC doesn't work like i think it should, would have to look it up)
Can someone explain what slow tourque path mean... is this the ASR?
Have a nice day
Martin

Because you're not directly asking the throttle to open, it goes through a circuit. You are not gona make that faster.
How quick an engine revs is how quickly it can get air in and out and rotate the mass of the crank through to the drivetrain. Unless it is running really badly, you're not gona tune it to rev noticeably any faster. The manufacturer didn't set revving speed to 70% or something you can turn up. It is the efficiency of the engine that dictates. It just does what it can do.

1. Should be moved to noob section.
2. Not a single log is posted, just bs theorycraft.
Post high-speed log of revving engine with throttle floored.
Although that too is a waste of time. Fit a lighter flywheel.

I agree. Without logs this thread is utterly pointless.

After the throttle servo delay there is nothing stopping you from revving, except if your ignition for some reason is very retarded or your mixture is fooked that it sputters for a bit before correcting itself. Otherwise fit a lighter flywheel, like others said  |
