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

    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.

    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!

    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.

    09 is l9h and 08 is l92. L92 is not flex. I know that was the addition to the l94 was only unsure of DOD Edit: l92/l9h/l94 L92 The L92 was introduced in 2007 for GM luxury pickups and SUVs. It was the first 6.2L LS truck engine. It was commonly known as the Vortec 6200. L9H The L9H replaced...

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

    Ok so I’m considering a 6.2 swap and moving the lmg to my fathers Chevelle as a surprise (after a cam and some other stuff) and this got me thinking so I checked. Delphi FG1054 is shared on both the 5.3 and 6.2 flex fuel engines in both the 2012 Tahoe and Escalade. I also checked the 5.3 in 2008...

    I believe the caddy 6.2 flex pump is different than the Tahoe 5.3 flex.

    That’s the shit for the head gaskets! Remember cometics can be reused up to 3 times. If the heads come off again for any reason remember that.

    No need for timing changes either to pass in NY. Had my car tuned for 2 years now got a sticker every time with headers and cats and no rear o2 sensors.

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

    I have my downstream sensors disabled and no reporting so it’s like they don’t exist and have been that way for a while. Passes emissions no problem. Still have cats but really only using them so I don’t smell the raw fuel from the exhaust. Long tubes don’t mean shit these days for emissions...

    So I can actually use IAT as it was designed to in addition to IAT2. IAT is in the MAF sensor. IAT2 is in the manifold. I have an LSA swap and IAT gets broken out from the MAF and used in the LSA lid temp sensor(IAT2) so IAT actually reads inside the supercharger lid(as long as you use the...

    E38 ecm uses I think connector 1 (top) pin 40 for the sensor signal wire. I’ll confirm it tomorrow. I want to figure out what pin is used for IAT2 Google gm vats hptuners and you’ll figure it out. EDIT: confirmed J1 pin 40 is signal wire
