2003_SuperSport Posted August 21, 2014 Report Share Posted August 21, 2014 I tried to do a data log on my 2007 colorado with the 3.7L using the basic default imperical configuration and another one that I use to convert to MAF HZ but I cant get the Knock to show on the data log while logging it just doesnt read... It shows reading 160 somthing parameters but the one I use alot (KNOCK) doesnt show... Wont show on the Histogram or any of the other moniters... Does anyone have a HPTuners Scan Configuration that they use to tune a stock 2007 colorado with the 3.7L that I can use to see if mine are setup right?. This truck eats the gas but with out the tune and 33" tires the MPH is off so will the estimated MPG... So once I tune the speedo it will read appropriately.... But the last time I checked I got only 13mpg driving fairly easy so probably 14 with the bigger uncalibrated tires... I'd be happy if I could tune out at 16mpg average but it may take some time to get there hence I need to see the knock burst LOL... Thanks a bunch Alright brothers... I posted this up in the colorado forums and it has been up 2 days now and not as much as a you are S.O.L... haha... So I figure some of you tuners out there or someone that has a colorado can hook me up with a scan config so I can read my Knock... I want to try it this way before I start digging into the mechanical part of it lol... I understand it may take a little longer here as its a different truck forum all together but it seems this forum is still more active...

2003_SuperSport Posted September 2, 2014 Author Report Share Posted September 2, 2014 Well, I ran a scan and did a very basic TQ management tune for now and recalibrate it for the correct tire size and corrected the speedo and I gained 4mpg's getting 16.5-17mpg mixed city and hwy driving from only 13 almost all hwy ... I am pleased so far, but am pretty sure some of it was because the tires were so big that it threw the odometer off a little... But with the TQM gone in the engine and 75% reduction in the tranny it has a night and day throttle response increase and the shifts respond a tad better and the hwy driving isnt downshifting back and forth anymore to keep up with crusie control set at 60mph lol... Now what to do with this bumblebee exhaust it has errrrr ... So annoying and I made it worse by sawzalling the rusty old exhaust back just after the muffler... The piping was shot with tons of holes and I could crush it with my hand in spots... Surprisingly the rest of the underneath is in outstanding shape still for a 7 year old vehicle....
