hey guys, i have an older truck 2001 sierra. i want the trinity to display MPG, how do i do this? is there a way to make a gauge that will calculate this for me besides doing the math. Only gm vehicles with the upscale fuel monitor like denali (y91) option code have a way to calculate this. this is a seperate gauge in the console so its not part of the DIC/IPC. Can trinity monitor this?

i have made some custom layouts...fuel volume, and tank capacity but im not sure what or how this is messured or why i need this. seems to be digital but only tell me numeric value nothing of gallons. im sure you guys know what im talking about.

some things i have noticed cuz i have a drive by cable truck i have to be carefull as to what parameters i want as gauges cuz it wont exist on my truck. ie throttle posistion, desired throttle,ect

so in short if there is no gauge for MPG's how hard could it be to email me one...or can that be done? Would trinity support a emailed added gauges?

throttle position is there for your truck - I have guys log it all the time for me for their custom tunes....

the one you want to log for that is "Absolute Throttle Position"


as for MPG, nah, that won't be there and ya can't create it... don't know if it's something they can come up with or not either...


the important ones you need to data log for checking/adjusting the tune are:


Long Term fuel trim bank 1

Long Term Fuel Trim Bank 2

Spark Advance

Intake air Temp

MAF Sensor Mass Air Flow

Knock Retard

Engine Speed (RPM)

Absolute Throttle Position


and those are all in there....

an MPG gauge is something we have been looking into...

Id like to have an MPG gauge to, can u keep an update on this?

yea i think this would be great "add on" gauges by like autometer or dashhawk have to use the OBD2 port so since trinity is already there...we need one....thanks guys

any update on this lew, mike ,or johan

nah... no update... much bigger stuff/higher priorities to worry about than that gauge... won't be for a while dude...
