Tunes and the dyno
I have read that after uploading a tune the ECU needs time to "learn". So my I question is how long does the ECU need to deliver the best results ? Can I fkash from stock and then dyno ? One side question...The dyno operator asked if there was easy access to a coil wire to dyno the car. Where is the best place to get an ignition signal ? Thanks in advance..

2.Connect a rpm signal from front passenger side coil
3.Connect air fuel in tail pipe
4. Do 2 pulls in 4th gear as the second pull is always the best run.
5.Shut down car and load tune and repeat.
I did 6 back to back pulls when we were tweaking my car and it kept making power until pull 7 and only lost about 5whp so these cars are pretty consistent on the Dyno
Don't worry about the car adapting.full throttle maps are hard programed and will run what the tune is calling for and will only pull timing if there is knock.
Bring usb stick to ask for the raw files
What your doing is the best for before and after because you can Dyno 2 hours later and get better or worse numbers as the ambient conditions change.
Good luck!

How is this done? I've searched, but as anyone can guess "dyno" and "mode" pulls up a phonebook...
I found it last night here are the steps.
1. Turn ignition to Position 1.
2 Mack sure odometer is on screen between the gauges.
3. Press and hold the answer call button on the right side of the steering wheel and the "OK" on the left side of the steering wheel.
4. Hold for about 5 seconds and a menu will appear select dynamometer. Click ok
5. Note this menu will stay active as long as the car is left on.
