What was I thinking need help lol

[[email protected]]

Hello everyone, So im new to Tuning as it seems many are. I just rebuilt my motor after snapping 2 rods for thinking i was aquaman and driving thru a crap ton of water. Anyway my build is a 2006 LM7 block with a gen 4 crank, rods, and pistons, a truck norris cam with the springs and rods, cold air intake, corvette servos in my 4l60e, everything else is stock. I am having massive trouble getting this thing to run, or even drive for that matter. can someone look at my logs and base tune to let me know where im screwing up at and help me get this thing running again. tired of sharing the mini van with my wife lmao06 Silverado 1st Tune Running.hptlog 06 after tune.hpl

Bank 2 is extremely lean per that log. Which is also missing lots of stuff. No o2 sensors or injector pulse width.

It's still a 5.3 with a larger camshaft now, it really shouldn't be giving you that much trouble. Yes the timing and fueling are going to need work but the fuel trims are showing an issue.

Double check fuel pressure, check for intake leaks and exhaust leaks.

Log B1S1 and B2S1 O2 voltages. Looks like B2 is dead. Got a few problems with sensors.

P0101 - Mass or Volume Air Flow A Circuit Range/Performance (Pending)
P0106 - Manifold Absolute Pressure/BARO Sensor Range/Performance (Pending)
P0174 - System Too Lean (Bank 2) (Pending)

Curious what was done to make the gen4 crank work with a p59. Was the reluctor changed or is there an adapter box involved?

P0101 - Mass or Volume Air Flow A Circuit Range/Performance (Pending) - This shows up because MAF and VE mismatch. Needs VE tuning
P0106 - Manifold Absolute Pressure/BARO Sensor Range/Performance (Pending) - This shows up because the PCM expects more vacuum than it has. The cam will produce less vacuum
P0174 - System Too Lean (Bank 2) (Pending) - There looks to be a problem with one bank (ps). I would need a longer log with both front o2's logged to diagnose.

Ok sorry for the delay with my response wife and kid stuff got me held up. But as far as the gen 4 crank I did swap reluctor wheels around. Also since the last log I changed the o2 sensors. I?ll update the log file that I have taken and share the new information with you guys. Thanks for all the reply?s and information on what to check.

Ok finally had a chance to get some work done and got to putt new maf , new map, new throttle body and o2 sensors. Its no longer running lean but im still getting the reduced engine power and its throwing codes at me and im so confused on why. I even went back thru and added extra grounds because thought it might be a grounding issue. Any advice on what i should do next ? i added the current tune and log. Thanks again

It's still got something goofy going on. The o2 sensors are dead for a little bit and fuel trims going insane and then they start working again and the fuel trims level out. Then it a little bit later they do the same things over again.

Is this still all installed in a Silverado or something different?

Did you use AC Delco or Denso sensors? If you use something like NGK or Bosch, those don't work in the LS engines, people always have problems.

Ignition timing for that camshaft should be around 18-20ish degrees too. 14 degrees is too low.

What codes is it throwing now?

[blindsquirrel]

NTK is one of the OE suppliers along with with Denso, GM used either depending on which way the wind was blowing that particular day.

Probably had a spinning wheel for the parts cannon at the morning meetings.

From the O2 trace, it looks like a lot of misfires on B2. That's why it's driving biased rich there compared to B1.

Use VCM Scanner>Vehicle Controls & Special functions to clear LTFT's and try again. Tune is set for STFT only, and latent LTFT's won't update like that. They're still affecting fueling, though. STFT is adding wherever LTFT is subtracting.

WHat codes specifically?

The fuel trims are all over the place in that short log. I don't see any mechanical issues right off.. just tuning. If the airflow model is incorrect and it is FBW you are likely to go into reduce power mode for that reason alone.

Ok so the O2 sensors are denso. And yes it went right back into the 2006 Silverado. The codes it’s throwing is the P0101 and P0106 which I see that Alvin addressed in the previous reply. When I read that at the time I completely didn’t understand what he meant. That being said how do I go about tuning getting my VE tables to correlate with the MAF tables. And I’ll try adjusting my timing tables and go from there. I appreciate your help and input.

Should I copy my maf tables over on the be side ? nm that was a dumb question lol. ill be back after i learn about VE lmao

[SiriusC1024]

No man just clear the LTFT's and log again. It'd be beneficial to re-enable LTFT's afterward. Certainly you'll have to tune, but this will take care of the current issue.

ok ill do it now.

Ok so i had to replace the o2 sensors and fix a few grounds. But after that i got everthing reading correctly. What should i do tune wise now. The car still throws the maf, the map, and the tps codes. Should be in the log file. Do i need to adjust these codes or something. Sorry for the long dely in replys. Its been a busy last few weeks.

Put in into SD and start tuning VE. Fix over/underspeed spark. Put it back to stock.

Do you have something I can compare this too? Also sorry for the dumb question but what is SD? Speed density? Very green here lol. Thank you for the reply.

Also should I turn ltft back off to tune my VE table.
