Big turbo fuelling logs - plz help

[str8ballin]

Hello,
I have never really logged my fuelling much but as im tweaking my setup with unisettings I thought I would take some logs of block 031.
My voltages are all over the place to start with - on idle i see .750, then all of a sudden 0.040 volts and it keeps fluctuating between 0.04 - 0.80!

ALso they dont match my AEM a/f gauge at all, on my gauge my fuelling looks normal , 14's idle and part throttle and on boost 11-12's but only after 4-4.5K when I actually make any boost! (gt3076r).

My question is, could these figures be scalled in any way with my map like they would with the MAF, or Tb?
Should I disregard block 031 and go by my AEM gauge?
Both have brand new sensors on them!

Also my MAF maxxes out @317.08 - should I look at getting that sorted or would he ecu just have its own parameters to run by after that like with the standard map sensor after it see's more than 1.5bar boost?

as you can see on the 2nd log, even when im cruising block 031 shows some crazy fuelling but on my aem it seems fine - also I have no faultcodes regarding fuelling ever.
ALso maybe someone can chime in on my timing numbers - not great I guess!

Hope someone can help!

This is my last try with the ME7.5 or im going stand-alone!

Thanks

Stupid question but is it a wideband ecu?

Hi mate, thanks for replying!
Actually it isnt wideband - I always thought it was but its the 4wire one - my harness and ecu is from same car as yours, ayp 06a906032aa ecu I think!

[DPJ]

I was going to ask if it was a wideband.

031 is no use to you.

Oh, thanks I had this feeling but wasnt sure! Can I use block 033?

My 032 fuel trims are 8.7% and -25%.

100% I dont have a leak - pressure tested to 1.8BAR.

thanks alot.
