I am having a hell of a refresher right now. Last time I tuned something was still with 2.24 on a Gen 3, lol. Truck has a BTR stage 2 truck cam and ARH 1 7/8 long tubes. Everything else is stock. I am trying to get the MAF tuned first and am having issue with say it 20 percent rich, I take away 10 percent away, and now its 20 percent lean. It reminds me of tuning a VE table that was way out of whack, haha. Idle is about the only thing giving me grief on the MAF tuning. I havent started playing with the O2 sample speeds and delays yet, but didnt know if i need to. Now as far as the VVE tuning goes. I am following Smokeshows write up pretty closely besides I am in full open loop being I never welded a bung for the wideband, so I am using Bank 1 O2 bung. I also had issues with filtering out the DFCO so I disabled that for now too. It seems that when I try to change values in the VVE, the results never come out right the next time I log after flashing. I seen stuff about only tuning per fuel trim cell but after watching Banish's GEN V video for the second time, he doesnt seem to be doing that. Any more write ups or help a ton. I tried already looking through the Gen 4 and 5 howtos and stickys. I tried searching gen v forums through Hptuners and through google. Kind of ending up stuck. I also am chasing a stall, but havnt started to look at that as of writing this. that is around 6:07:09:000.
Thanks
Eric
