engines are simple... Air, Fuel, Spark... And they'll run! The amount of Air, Fuel, or Spark, will determine how the engine runs... Those 3 items you'll want to keep you eye on. Torque Pro app and the ELM Bluetooth adapter is a great way (cheap) to see what's happening in real time. But as mentioned, you'll need a bit of reading, research and discovery to make it all apparent to you. Don't rush, take your time, concentrate on just one thing at a time rather than trying to take it ALL in. It won't take long then...
great thing is this forum is very proactive on the platform, sure, you'll get yours busted a bit being a newbie, but it comes with the territory, lol. Use the search here and google and you'll be surprised what nfo you can find. Is using google, you could search and then put "Grandprixforums.net" on the end (without quotes) and will pop up threads here with the search item.
good luck!
and oh, yeah, your question...
