LTBx & STBx scanning question

[MarkZ]

2007 Cobalt 2.4L with ZZP Stage 1 S/C and full ZZP catt'd hearer and 3" exhaust.

Stupid new at this...bear with me. Did some scanning today on a 20 minute cruise on the highway.

LTB1 is 29.7, STB1 jumps around between 2 and 32.
STB2 and LTB2 are both -100 and not moving.

So, bad MAF or vacuum leak? This isn't even close to normal from what i've researched right?

This is going to be one hell of an experience!

O2B2 is zero....INJB2 is zero.

Am I running on only 2 cylinders?
Or does a 4 cylinder not use bank 2?

[Jaxon]

You only have 1 bank of cylinders so yeah, 4 cyl has no bank 2. Bank 1 is whatever bank that has cyl 1.

Sometimes your scanner config can also cause mis-reads......... (having certain pids in it). Try doing just a brand new config file with just the fuel trim stuff and see if it reads right......

If it's not that and there is a prob........ perhaps O2's faulty? injector issue, vac leak, maf......... could be any number of things........ need to put up a log file.

Anything with bank 2 do not log because you only have 1 bank.

I installed their kit last summer. Any luck with a better tune?

[hhrfreek]

Their base tune is ok. Though a ton of fine tuning can be done to make it better/more drivable. I have reworked almost everything. I've since bumped up to 60lbs inj and 3.1 pulley. A SC on this motor makes good power. Good luck.
