"Noise" refers to electrical noise; radio frequency interference(RFI). I it caused by rapid changes in current direction and/or voltage, like the alternator or ignition coil. That RFI induces current in all the wires attached to the ECU. Microprocessors are extremely sensitive to this and RFI can cause false triggers, resets, and even memory corruption in extreme cases. Shielding and good grounds provide paths for the induced current to bypass the ECU.
As for boost by gear being tricky, would it be easier to set up boost by speed then, using the vehicle speed sensor?
I was going to look in TunerStudio to see what the settings and options are, but either TS or the Java Platform it runs under is misbehaving. I'll have to get back to that one.
Lastly, did you tune it yourself, how hard was it if so, and what was your experience with tuning beforehand?
Well, I'm still
tuning my car.
Acceleration enrichment is a PITA, but tuning transients is always more difficult. Steady-state tuning is easy; drive the car, record lots of data logs, analyze them, tweak the tune, rinse & repeat. Tuning transients is more about achieving what feels right in practice than what looks right on the instruments.
I started with an old MS-I v2.2 back in '05 as a toy of sorts. I put it on a stationary engine with a long serial cable connected to an even older desktop computer. It was an excellent primer for the real deal because I got to do the whole install, tuning, and troubleshooting process on an engine that was expendable. One of the best lessons involved RFI and high voltage...
