Editing Street Tuning (section)

==Step 5. Driving==
I set up the mixture meter on the dash directly behind the steering wheel so that i could see the mixtures without taking my eye off the road.
I basically started driving around my streets, slowly, and tweaked the mixtures to get 14.7:1. I found myself pulling over and adjusting blocks of cells then driving again, etc. etc.
Got to the stage where i was driving around on light throttle with the mixtures all looking good. I then started giving it small amounts of acceleration and adjusting mixtures accordingly. Under any of these "not normal cruising but still light-medium accelerations" i made those areas on the fuel map give me 13:1. I think this was around 50% load. I then gave it a bit of a full throttle run, but backed off as the mixtures were showing <10:1
So i leaned up the top section of the map a bit, and gave me 11:1, which was still way rich, the car didn't want to rev very quickly above 4000 rpm because of this. That was enough for today as I could not keep tuning full throttle with my eye on the mixture gauge, I needed to come up with a way to log data.

I ended up buying a USB to serial adapter, which then gave me 2 serial ports on my laptop. I plugged the wolf into one, and the mixture meter into the other, and ran both the wolf and the mixture measuring software at once. I then ran a screen capture program, which had a shortcut key to start and stop recording. It all worked quite nicely.
This allowed me to continue tuning with different amounts of load (different gradient hills, accelerating with foot on the brake simulates hills quite nicely) and also full throttle. I could then pull over, and replay the screen capture seeing the load/rpm and mixtures on screen at the same time. Need to keep glancing at the meter a lot under full throttle still, just to make sure that the mixtures aren't going way off, such as the 15:1 that i saw once at around 80% load, accompanied with some severe pinging! Oh well, this engine is relatively disposable anyway... I suppose some pinging every now and then is inevitable while tuning from scratch on the street.
You need to concentrate on the sound of the engine too, any rattles, back off immediately, check the logs and richen the mixtures if necessary, otherwise back off the timing a few degrees at that load/rpm point.

Thats how i worked out to get a basic tune down, if anyone has any more information to add, or any faults to pick out of what i said, please add it below, or let me know.
