I made some changes to IRL/IOP/axis to reflect the new load.
Last minute changes to the map since last night:
bumped up IRL/IOP/AXIS to be higher than LDRXN
From what I saw in the brief log I was able to get, the load and boost are doing exactly what NYET said. Apparently I had my maps set too low, and not following LDRXN because of it. That is, if I am understanding it correctly.
It definitely is noticed. Before when load/boost was off, I could actually hear the turbo spool down when the ecu wasn't happy with what was going on. This morning it was a much smoother pull.

This chart from the same log shows that WGDC. I need to adjust my desired boost so the PID doesn't just fall out trying to limit boost. Its a problem, but a nice problem...the turbo wants to spool faster and now.

Boost after a correction to the maps. I am going to adjust LDR to keep requested around 27psi.
I am thinking of also moving the 4500 rpm point in my PID to 4250 since my turbo is spooling before this point now, and I need the duty cycle to drop around there.

My best so far. This time without pushing 30psi  . Thanks you guys for the pointer on dialing back the boost. I still thin the timing is low, and I still have work to do to the PID. |

I am still having trouble getting the boost to get to where its set and stay put. I like how the car spooled with a with it set to 29-30psi.

Looking through my .bin, I have noticed that my KFLDIMX Mbar axis is 1/2 of what it should read. i dont know how it happenned.
I have been trying to properly define the axis I need so I can make the adjustments. All I do, nothing looks quite right.

That mbar axis (stock) is plsolr_w (relative requested boost, basically plsol_w - ambient pressure), 0-1000mBar stock on ME7.1 so with the 5120 hack you should have 0-2000mBar range, assuming you have both plsol and pu_w scaled.. btw not sure if this is coincidence, but we're talking about it here too http://nefariousmotorsports.com/forum/index.php?topic=3280.msg33048#msg33048 |

DUH, I totally forgot about the hack cutting things in half.

After seeing my AFR's take a crap across the board again, I went back into trouble shooting hardware issues. I have been beating myself up lately with the very inconsistent fueling of the car. One log its decent to ok, next log its pig rich, next log rich-lean-rich. Come to find out my new inline fuel pump was taking a crap. Only way I found out was by replacing it and with no other changes to the tune:

My fueling never really followed requested either it was too rich or too lean and did its own thing the whole way.

What are you guys doing to get more timing into the motors without going methanol injection? I still cant get the timing to stay decent around 4200rpms when my turbo is fully spooled.
Should I get to a richer AFR sooner?

What fuel are you running?
I would target richer mixture earlier, say 0.9 upon WOT taper to like 0.80 at full boost.

maybe. Its gonna be tough w/o meth or lowering your CR |

I am running WA state 92 OCT. I just changed my KFLAMKRL to add more fuel faster according to load: |
