Hi!

Feel free to shoot me down here but, I see some of the info on the Syvecs forum is stored in files via links or attachments, which makes it hard to find keywords when searching the forum. I get it that these docs may need to be given a link so they can be kept up to date elsewhere but, you find yourself digging around for some time to find what could’ve taken seconds to discover if not posted via a link or an attachment.
To help with this forum’s search function, it would be favourable to copy/paste the contents of the below PDF into a post, that way, it will be searchable and bring users to this thread for updated PDF attachments or links that may be posted in the future.

So, yeah, that’s what I’ve posted below…




Syvecs Parameters – Abbreviations

CalSwitch – Calibration switch position
CCP – Crank Case Pressure
CllEnable – Closed Loop Lambda Enable
CllTarget – Closed Loop Lambda Target Air/Fuel Ratio
Cyl1knock – Raw Knock Value on Cylinder 1
Cyl1knockthresh – Cylinder 1 Knock threshold limit before timing adjustment occurs
Cyl1knockIgnRtd – Cylinder 1 Knock Control retard amount
DrivenSpeed – Driven wheel speed
DIP - Direct Injection Pressure
ECT – Engine Coolant Temp
EGT – Exhaust Gas Temp
ECP - Engine Coolant Pressure
Engine Enable – States if any Trips or Limps are present
EngTrqEstOutputTrans - Torque Output sent to TCM

EOP – Engine Oil Pressure
EOT – Engine Oil Temp
FLV - Fuel Level
FlSpeed - Front Left Speed
FuelComp - Fuel Composition %
FP – Fuel Pressure
FT – Fuel Temp
