Ultimate Guide to Parameter Monitoring?

[Sid3wayS]

Ltft & stft: basicly how much fuel your motor takes and adds to reach your targeted afr. These numbers vary but on an ots map should be +/- 8 of each other, on a custom tune will be generaly +/- 4. The closer these numbers are the better because your ecu is not going crazy trying to keep things in check. Envirment, wether and fuel quality are just some things that affect the numbers.

Bats: the temperature of the air as it is being ingested bu the motor. Gor the most art the colder the better. Upgrading intercoolers, shooting meth and using insulation will lower this number. No real constant number because it depend on your mods.

Iat: is the temp of the air getting sucked in. Explained up top

Wgdc: is how much your waste gate on the turbo opens and closes. It very basicly controls the boost levels by diverting the exahuat gases away from the turbo, more it opens the less gasses hit the turbo, the more it closes, the more gasses hit the turbo. The more gas that hots the fins the faster it spins and more boost is made. This is a percenatge from 1-100. 1 is open and 100 is closed.

Again these are very vague refrences and are just to give a basic idea of what each value is and represents. Like @NCZ13 knowing what they mean and having a general idea of the values go hand in hand and take alot of reading.
