    Bw s256 turbo with 3 in glass pack dumped pre axle raptor liner bed and top rails and fenderflares and rocker panels. Hunter side steps. Plasti-dipped upper fenders and emblems. satin black spray paint here and there inside and out. 5100's set to 1.75" up front . C channel front bumper. Maxxis bighorn 255/85/16
    Not sure... But they definitely werent causing my issue and that was the main point of this wellness visit... I guess my next option would be to swap injectors around and see if the issue follows... One of them could be spraying too much maybe? There is now way to tune independently around that either if I pull fuel to correct bank 2 then bank 1 goes lean.

    Having them cleaned and flow tested makes sure that they are as close to possible as can be, since you cannot individually cylinder tune.

    I got a tuner theory question: let's say I'm at idle with 14.7 AFR and my ignition angle is 12 degrees. Let's say I add 5 degrees to my ignition angle, so I'm now at 17 degrees and my AFR is 15.2. This tells me I just got worst fuel economy because I'd need to add fuel to get back to my previous 14.7, correct? So if I adjusted my timing to a degree that yielded a richer AFR I'd need to remove fuel to get back to 14.7, increasing fuel economy yes?

    If true I'd also assume the same can be said for the VVTI timing, adjust until richest AFR for best idle fuel economy. And of course all things said with the assumption that idle stays smooth.

    Your (my) Afr will bounce around back and forth (I'm narrow band so slower). Technically 15.2 would be better gas mileage because it is lean or less fuel. One of my friends Civics was running 17:1 afr. A negative side to too lean is weird or out of spec emissions (I think nox, could be another).

    After I found that ignition angle and VVTI I'd go to my fuel table and adjust it to get back to 14.7, it should be a lower number thus my assumption that this is how to get to a better fuel economy at idle.

    edit:
    this is rubbish if VE tuning

    An issue I can't rectify to my liking is AC control because of the way the Tacoma wiring is, maybe one of you guys can give me a fresh outlook. On Low fan setting, and sometimes the next speed up (M1), the clutch will not stay engaged the whole time; when it engages/disengages, the setting I have dialed in to work well for the respective conditions are different enough that the change throws the idle out of wack momentarily (not as smooth as it should be). I've made adjustments to counter this but leaves me idling at a higher RPM than I'd like while in AC condition. The problem, I feel and as far as I know, is there is no signal that I can easily tap into that says the vehicle is in AC condition; the wiring I can access is signal to IDLE UP or ENGAGE CLUTCH (same-same). I want to idle up while in A/C condition, regardless of clutch condition, and idle slightly higher while also adjusting timing on clutch condition. Has anyone overcome this or have any ideas from looking at the wiring diagram? @Torspd thinking of you specifically friend.

    For the longest time, I had no A/C. Then I got that back working, and there was the associated idle related change. With the little time that I spent on it, I came to a similar conclusion. Where to wire to for a signal, and how best to remedy the tune. For mine, I settled with adjusting the tune, as if was the easiest solution for my needs at the time. With the added load of the a/c or not.

    I do have a hunch that there is a short segment covered about this exact topic, in the YouTube series, The Skid Factory. I don’t remember the specifics, but I remember them outlining a diagram. One of the earlier episodes. Which would be on MCM2

    I had no a.c. for 3 years... I poked a hole in my condenser mounting my IC... But I got cold air now... Is it in the switch? I think there is a write up somewhere in replacing some resistors for fans that only blow on high it's a common issue

    I spent yesterday, literally the whole day, removing everything up to and including the front diff to remove the oil pan so that I could replace the upper oil pan with my new oil return lines. soooo many bolts and that little diff is harder to get in/out of there than it has to be due to the breather lines getting hung up :goingcrazy:

    Next up is remaking the intercooler piping. I don't have much, but I've scratched it to hell and would like to move a bung.
    This is on the way, I'll report how it works:

    My buddy used that roller to make a firewall on his drag truck. It’s tricky, but does the job.
    I can ask him for some lessons learned if you’re interested.

    Those are cool. Panels look so good. Heard they are a pain to first get the hang of.

    I've got a few drops to practice on, I usually learn pretty quick but we'll see

    Take some progression pictures for sure. I am tired of using argon to build weld puddle bead rolls.

    Well, boys. Wish me luck, started the process of putting the forged build back in.

    You're too kind, but thank you!. Too many projects and it looks like a tornado went through there right now.
