Go wideband

Im sorting out hardware today. I have a good feeling its coming from my block off plate that I made. Compressed air was the easiest method I made to check for vac leaks when refering to hiss. will also drop in a filter just because it needs one.

If running 550 at 4bar on a stock pump is crazy should I run my 3bar till I get everything sorted or should I go ahead and drop in my Walbro 255lph??

rightnow its starts right up, it idles and its getting fuel (alot for that matter)
 

Fixed my boost leak (now @-22hg), found acouple lines split and fixed the block off. Dropped in the new filter(sucked), got rid of the recently discovered 5bar and replaced it with 3bar.  flashed in KRKTE @ 0.06012 acccording to the changed flow rate and then went back to stock with TVUB (didnt like new values @ idle).

Idle looked better at 14.6, part throttle seemd better hanging around 13.8-14.0 and then went WOT for acouple seconds (sorry had to) and that went rich but not as rich as b4 11.1-10.8.


1st log is at idle

2nd log is at part throttle

3rd is very shortly at WOT


Do I just edit KRKTE to fix WOT

So in general once STFTs and LTFTs are within spec at idle and PT, should WOT follow...roughly?

Not trying to jump the gun here just somthing to think about as I progress and got everything in front of me.

Thanks alot for the advice so far, prob wouldnt have found that 5bar anytime soon if you didnt send me down the line of hardware.

As of rightnow im waiting for an email back from Ross so I can be unlocked and get my trims inline. At the same time ive been going back and forth to the bench on a spree(twice really) of trial and error making very minimum changes(not much at all) cause my WB gauge has been very handy.

Question about TVUB. When scaling (in the future), my axis are set at 8 10 12 (14) 16 and looking at logs UB seems to operate mainly between 13.6-13.8v. should I change the axis accordingly or does it not have that much effect between 13.6 and 14?

     

I need some help.

Did what you and Daz said in 1 of the stickies and drove around for 15mins and watched VCDS (sorry bout the cut out on the pic but thrs no data behind it anyways) and trims look way off.

Tried acouple diffrent KRKTE and found 0.0716 to be best. Part throttle looks good up to a certain load point by the actual AFR. But as soon as I let off or sitting at a light it gets really rich beyond my gauge.

should I be scaling TVUB mainly at the 12 to 14v points or is there another approach?

Its alittle better but still go rich as soon as I dip into WOT, maybe I should drop in my Walbro 255lph?

Yeah I think I found a acceptable starting point at idle it’s now at 15.1-14.6. Even part throttle will hang around 13.8 but after 3sec into WOT it’ll fall into 11.1-10.6 b4 I let off then it’ll come back into place.

It’s getting better cause it pulls harder at part throttle then it did with stock inj at wot. Just wasn’t sure if I should make anymore change b4 upgrading the pump?
