Tuning basics
Ok, this will open things up for discussion and many questions. As far as your basic tuning with a predator, LS1 edit, HP tuners, etc. Big things to watch are going to be Fuel trims and timing. Datalogging is going to be the key here. This is where you will see the effects of your changes. You will look at LTFT's (long term fuel trims) looking for -4 area after about 50 miles of driving. Be careful with getting too aggressive with timing tables. Watch the logs for knock retard and adjust those areas accordingly. Most people will not have the one most vital tuning instrument, a wideband o2. This tool is instrumental in tuning for WOT. Many cars that we have seen are actually too lean in power enrichment as delivered from the factory. So, the best suggestion is get the car on the rollers or buy a wideband kit. Lean conditions are the greatest enemy to DIY tuning that I have seen. I am now ready for the questions.
