Turbo BS Thread

well I kinda meant a bubblie T with a bit more of a rounded aspect thing goin on haha but if you aleady have your collector/ypipe thing and this will go in to it

 

Jstand

 

not you, the had asked how jstand knew how much boost he was running

 

@Torspd did you have any critiques on my fuel trims and stuff from yesterday? also truck did not fire up on the first attempt but did on the second and warmed up and idled fine without dying so... headed in the right direction

 

Did you revert back to the table previous to the fuel decel cut enriching?

 

I went back and pulled all the fuel back down to like -.36v for everything under 20 inhg and I think I'm somewhere around -.33v up to 0 past that

 

Sounds like you solved it. How are your half throttle trims/AFR's, and full throttle?

 

I do have a separate boost gauge. The app doesn't read boost

 

well yesterday it seemed like my half throttle afr's took a second to catch up like I got to 3 or 4 psi before they dipped below 12 but wot is instant rich. short term fuel trims go to 0 ltft go 0 and -5 under boost

 

Ok, good.

 

How rich is "instant rich"?

 

I have the same boost gauge and AEM afr gauge for a little while now

 

under 12 I meant instant rich like pedal goes to floor, afrs don't hang out in the 14's atall

 

Ok. Good.

In your full boost area, I recommend already being in the high 11's. If you up it to 8 psi, make sure you are low to mid 11's AFR.

 

I still don't have an afr gauge installed and torque only goes down to 12.1 but next year I plan on taking it and getting it dyno tuned and then I will be able to have a proper tune, and numbers to go with and they will be monitoring actual afrs below 12

 

i had a turbo build without afr. regretted it. im putting one on my honda even though its n/a for a while, but i also plan on tuning it myself (well start dabbling in it at least)

 

I had a stroker engine build without a oil pressure gauge. Regretted it.

Gauges prevent mental breakdowns.

 

lol im sure that one hurt. i had oil pressure/temp ad water temp on that build. which ill eventually add the temps to this one too.

 

So I'm good at high 10's low 11's with 8-9 psi. Maybe room for more e85 or 10psi but the difference would be that i don't have a tune.

 

Just don't use leaded fuel.
