    Yeah because it needs a proper tune. What did you change from the original tune?

    Ffs leave the effin timing alone u til you put in the wideband! You’re going to blow it up getting ahead of yourself!!! Foe the love of god someone please talk some sense into him. Idc if it’s not my money spent it’s careless to throw different timing maps at an engine because they feel like...

    Hope you have a wideband coming in the mail so you can finish tuning it properly before you blow it up

    Oh yeah almost forgot if you do not have dod/afm I would suggest using 2010-2015 camaro ls3 manual tune file for the best n/a timing. IIRC you are using the ls3 cam anyways.

    Don’t pull timing if you have KR add more fuel via maf hz it’s retarding at and go out and repeat and see if it’s still there. Keep adding fuel this way until no more KR exists or it doesn’t make a difference and only then you should retard the timing table in ** and make sure the LO table...

    You better stop punching it if your aren’t logging it with vcm scanner. You could be hitting insane knock retard and could detonate.

    Hell yeah it is! They love timing. I can’t wait to finish tuning on 93 with my LSA so I can tune on e85 and throw more timing at it! I installed an aux pump on my car recently and it threw my tune way off because of the pressure now but I figured out how to control the fuel pressure so the...

    Open a graph boost from -30 0 and 30 use the sensor under math for boost. It’ll show -1x to 0 if your map sensor is working correctly

    Yeah it sucks ghat there is no standard anymore. They all suck. You expect one thing and get another. The truck definitely doesn’t have any gas left in it. Been going to Sunoco that was a Valero before and a Valero way out east on Thursday’s. Haven’t gone to the one across from a speed shop need...

    Yeah huh? Which one would you suggest? Dsx tuning uses the gm one on all their kits.

    Oil pressure back up. Screen was clogged and replaced the screen and sensor while I was back there. Prolly going to keep the other sensor as a backup. Woot woot. Used that fancy lisle socket too! I will prolly put a real ethanol sensor in this truck as well too since I already paid for the...

    No man. It’s like a .02 difference in lambda. That’s why it’s negligible.
  14. 08z71bgm

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    The difference before and after car is negligible so it doesn’t matter

    You don’t need to weld or drill anything. Disable the rear o2 and use the same ******** for the wideband. Look up erm performance tuning. I forgot who owns the rights now since he passed away.

    GRG ftw. Between that and the book from ERM performance it’s cake. No pro features here and I used an aem wideband that uses obd2 so it can poll faster. 30-0334 is the part number. Goes between the cars obd2 and hptuners. Lambda lambda lambda!

    Lol let the engine builder build his engine and engineer his new oiling system. The internet knows best

    Learn to tune it yourself. That’s what I did after a really delayed update from remote tuner. Hptuners and the internet FTW! Once you understand what to log and what you’re looking at it’s easier to figure out what needs to be done to fix it.

    I’m using comp cams max lift BSR rockers. Love them. They make em for ls1 style ls3 style and ls7 style. I wanted to get a trunion upgrade then saw these and I couldn’t be happier.
