I like how you drive. I will show this to my students, to see if their can pick up how you drive. I am trying to teach them tuning without driving a car. Just tune from Logs!!! Lol.

I'd be impressed if you could teach me to understand my own driving!

v2 ROM has improved the linear throttle response without the sudden but exciting AVCS. No flat spots or hesitancy for everything above 2000rpm
Looking forward to seeing the Dyno chart.
Interested in raising the RPM limiter to maybe 7500 for the next version perhaps.

Hi Edward,

Please see v3 log attached.
Pretty sure I managed full pulls in 2,3+4 but it took a little longer as the roads were busier.

It certainly feels quicker:-)
I used BMW Power App for my iPod Touch and it reckoned 0-100km/h was only 5.41 sec
Can you tell the real time from the log (without timestamps)?

I tried to hit the rev limiter and think I was successful. Regardless, the drive is certainly improved by not hitting the stock limiter.
Interestingly the analogue rev counter indicated 8000rpm but the log shows it was somewhat lower at 7526.

A little hesitation below 2000rpm but again I think the engine was still cold.
Fuel went just below 3/4 during the drive.
Air Con off
Just me in the car.

Let me know if you need any more info.

Many Thanks,
Neil

I set your limiter to 7500 and not 8000rpm, as I do not know what oil you use and limited power there.

Can you record the sound of the car witht he new rev limit? It must sound really cruel.

Tuning is almost completed just for cold weather. Further tuning will be needed for hot weather.

Amsoil Synthetic 5W-30 High Performance PETROL Engine Oil

Stock is supposed to be 7200rpm IIRC but the extra 300 feels like so much more

[missing-snowman]

Will see if I can record it, but it didn't sound like the engine was straining at all
