I have a few questions about timing and fuel injection quanity oh and just about everything):h

I was wondering if anybody has played with any of the timing maps yet and wich way to go for power or economy? I was messing around with the throttle based injection quanity {B0727} I was wondering how high you could go on the fuel quanity before rail pressures drop off, has anyone gone up to 200mm3 yet?I'm still trying to learn the scan tool and data logger lots of info to take in. I havent loaded any tunes yet cause my laptop battery is junk and I tested for voltage between my power inverter and a ground on my laptop and I had as much as .100 volts. Whats safe? I have a new battery on the way. Is there a PID that is for defueling before shifts?

So many questions Thanks Robert

I have been just working with B0727 and B0720 and have had some hit and miss results, as expected with trial and error. Some good advise, don't add alot of fuel at less than 40% throttle and don't increase your pulse width below 1800 RPM this made for some real bad driving characteristics. Keep in mind where your daily driving throttle position is a don't go overboard. It took a couple of shots, but I'm starting to get the hang of it.
