VZ SV6 - high fuel consumption!!!!

[newjack]

Hi, got a full exhuast system and intake on my vz sv6 the other day...
No engine code came up, everything was running well.
Noticed I was averaging 17L/100km cruising around.
Tried reseting the ecu by disconnecting the battery (left it for 30min)..
Took it for a 20min drive around the block and still the same.
Do I have to drive it in over a while to let it reconfigure? Otherwise what do I do!!
Thanks

LTFT (Long Term Fuel Trim) Have a look at this figure on a scan tool this will tell you a lot of information.
Also have a look at the o2 sensor reading and on a scope to see its frequency and cross counts.

This is what I am getting from my VE SV6

Guessing since you just got the exhaust done you're driving with a heavy right foot and enjoying the droney v6 goodness.

Seriously though, drive around all sorts of areas (down highway, around town etc.) and then worry about it if it doesn't drop down

It sorted itself out after about half a tank of fuel. Very happy now !!!
