  1. I put a few miles on it now with the way it is...

    I put a few miles on it now with the way it is above. Seems to be working but I can't really tell if it's controlling all injectors off of the one sensor. My wideband bounces nicely around 14.7 (92...
  2. If I have to move both sensors to the down pipe...

    If I have to move both sensors to the down pipe and add a bung I'll just extend the factory harness.

    I just put a brand new O2 sensor in the downpipe (bank 2). Going to run the stock one in bank...
  3. From what I've been able to find from searching...

    From what I've been able to find from searching google, it sounds like the PCM needs to see input from both O2s in order for it to be able to go into closed loop. It sounds like I need two installed...
  4. Running a single O2 sensor in my turbo down pipe for closed loop?

    I've been running my truck OLSD ever since it was tuned in June. My stock O2 sensors are bad so that was the reason for that. Back when I tried closed loop before (one sensor in crossover pipe-bank 1...

    I just read this whole thread after doing a search about this unlocking while coasting problem.

    ^What did you set yours to and how did it fix it? What do each if those values mean exactly?^
  6. I find that going to google and typing in your...

    I find that going to google and typing in your question, then just adding "hptuners" to the end of your phrase will get you some good results usually pointing you back to the forum or another helpful...

    Wow sweet, thank you. I'm not sure if I'll get to try that tune out because I discovered after a few more hours of searching about MAP sensors that the one that I have turns out to be the 3.3bar...
  8. Yes. That is what I forgot to add to the first...

    Yes. That is what I forgot to add to the first post. Lots of the search results I got were people trying to run a different tune with the wrong sensor. I have this one. Just a basic 3 bar sensor....
  9. Upgrade from 1bar to 3bar and now it barely runs!

    I just got my truck fired up last weekend and was able to run it well enough below boost to get about 10 miles on it. I kept the 1 bar tune for testing before going to 3 bar. I upgraded to 3 bar...

    Fuel tank pressure. Good idea! I didn't come across that one while searching about this problem. I've seen the A/C sensor before, which I am using A/C. I did delete the fuel tank pressure sensor...
  11. Is there any way to get egr on a 3 bar tune? 2005 Silverado.

    Like many, I have my wideband hooked up to the egr input of my computer. Little did I know, once upgrading to the 3 bar, I lost the egr enable option.

    Can I send my tune in and get just that one...
  12. 2005 LQ4 Denali tune into my 2005 Silverado PCM?

    My pickup originally had a 4.8 liter, now it has a 6.6.

    When I originally got it running I just did some basic changes to my stock tune. Changed displacement, copied VE table from a "stock...

    Maybe a dumb question... how are you running it on the stock MAP sensor?

    I should add that both the scanner and the gauge are being fed by the same Analog output 2 wire from the wideband controller, thus making it more confusing to me. I checked the custom pid and the...

    Narrowband Voltage Rnage?

    I have an LC-1 wired to my EGR of the PCM. I also have the innovate digital air fuel gauge. When I first hooked everything up, it all worked great and read equal. Now a few weeks later, I have...

    With the key in, ignition on the MIL light turns on? That is normal with almost any stock car.
  17. Just tried that but it did not change anything. I...

    Just tried that but it did not change anything. I am still maxing out at 35 degrees. I can't find anything that would be limiting it, but I am not as smart as most of you.

    I commanded up to 38...
  18. Really? I've done my idle airflow tables a few...

    Really? I've done my idle airflow tables a few times already just as I got the rest more dialed in. I used rink rat's thread. What exactly are you seeing?
  19. Here you go, I tried that but nothing changed....

    Here you go, I tried that but nothing changed. This is weird. I wonder what it's even going off of right now to get the numbers of 35? I also just noticed that 35 is the highest it hits. Is this some...
  20. My timing is only hitting 35*, no higher. Why

    This is on my Blazer, Vortec 5.7 and 411 PCM. I am trying to increase the timing but nothing is changing in my logs. I can add 10* to the HO Spark table, LO spark table, idle in drive, and idle in...

    If you're going to install a turbo setup on your truck, fuel pumps and injectors should be one of your lesser worries. Pumps are easy to setup and so are injectors compared to building an entire...
  22. Poor Deceleration "cruise control" feeling. Also DFCO question

    Hey guys, I've been tuning my truck for about a month now. It used to have a 4.8l and now it has a 402. I started with a stock 6.0 tune and have got it pretty dialed in (I think).

    My problem is...

    The idle tuning how-to is a great thread. I kind of had the same problems as you at first with the idle and that post got me pretty close pretty quickly.

    This is probably way off from your problem but mine did this recently. Keep in mind though that I have a Chevy Blazer which swapped to an 0411 PCM when I vortec swapped the truck.
