Yeah - I'm not keen on working out in this weather. I spent an hour or so working on the AC/heater blower motor - it was cutting out intermittently. Tested all the sensors & only thing I could find was that applying pressure to the fan motor connector seemed to restore full fan operation. I just tie wrapped around the fan casing to pull the connector up & secured the wiring so it wasn't hanging free. I need to do the right front wheel bearing - it's started howling in this very cold weather.

Couldn't get TunerPro to connect when I left work, so I ran a Logworks log from today - values are more inline with what I was seeing using TT. WOT settings are all stock. Need to enrich upper cells now. Rich area at part throttle needs attention. Timing values at that point are from the 2nd to top load cells. Max 21psi (249kPa) boost. I think I can add a degree or two in the upper load cell in this weather. Added 3% to the top load row >5600

Where are you getting those STFT numbers from? Doesn't seem right that you have STFTs when full throttle...

Also, your coolant temp only maxed to 76ºC, seems really low to me.

Nice to see your air flow numbers actually correct now ;)

I have a 167 degree thermostat. I lowered the fan speed so that normal operating temp at extended idle does not exceed 85 degreec C

The STFT values are pulled from the ECU via the OT-2 - 4 channels can be drawn.

Yes -1270 kg/h (353) is now max recorded value instead of being stuck at 231 :D

The way I remember it is that O2 feed back it not fully disabled but only reduced above ~4k RPM. So the ECU seems to be adjusting for some of the lean condition that he is having mainly because of the dropping fuel pressure.

H you need to address your fuel pressure problems.

Yeah, the fuel pumps are installed, but I can't plumb the fuel lines, FPR & new rail until the weather is warm and my Fiat is back on the road. So, I just won't run over 21 psi until then.

I'm more concerned with the part throttle stutter/rich condition - I can always lean out the top once I have the volume at high load taken care of.

EDIT: IGNORE boost & AFR gauges - those are not connected to my setup - the values are meaningless in the context of my setup!

First time I've seen any evidence of knock - I was beginning to think maybe I had a problem with the KS setup... wonder why cyl #2?

Log file

start around 1;15 then around 7:15

Still very rich part throttle. I need to get the AFR hooked up so I can compare load/rpm/AFR & figure out where to make changes more precisely

Have to add a diode on the red terminal 16 feed to the VAG-COM, at it is, if I connect another device to the ODBII port, it backfeeds the VAG-COM.

Identified a couple of specific part throttle rich areas - I took screen shots right as the AFR's dumped below 12 at part throttle...

Took a fair bit out of the VE map, and increased the WOT map instead, since I hit 100% load cells by 30% throttle or earlier. Still hit some rich areas, so more work is needed but it's getting there. Short pull log, AFR's were better, no knock recorded. 64-114 is about 5sec, with two shifts, so tuning level is on par with the TTusb map I was running. What's getting to be a pain is that several logs didn't save properly, so I can't access them. Of course it's the ones that I most wanted to evaluate.

Installed the wiring from the AEM WBO2 to the rear O2 input wire and hooked up my oil temp sender to Logworks SSI-4 yesterday, it was relatively warm out. I set the formula in the ADX with Simply Volvo's assistance, so I can start logging AFR's in TunerPro today.

Still working on the part throttle / med-high load hiccup. Tweaked the VE & timing some more - leaned out more of the VE map, and added a couple of degrees timing in some of the higher load cells. Warmup has a slight glitch - typically after 15-20 sec it can bog (depends on ambient temp to some extent) & stall if I don't catch it & give it a little pedal to level it back off. Since the warmup table have no temp axis value - I'm wondering if I need to modify the ignition table by coolant temp - that might do it...

Also, since switching to this setup I now get a TCV 0243 code on hard accel runs - I have the basic TCV parameters set to prevent registering a overboost situation, but something in one of these parameters needs fixing. TCV duty is either 49.6% or 0...

Time passed / speed seems skewed - according to this (2-4th log I posted the dash screenshots from earlier) I went from 47.22mph to 91.96 in 2.7sec.

No timing pull. Seems like WOT is recorded as only 85%, pretty sure I was pedal to the metal on this one.

I have reduced throttle angle required. Moved the time for max & min settings the extreme ends of scale. Since I use an EBC, I don't need any of this crap to be active. I have a working TCV connected, as with TTusb it would set a code without that connected. Maybe I should go the other extreme & set LDR thresholds to much higher throttle angles.

I never got a code for the TCV as long as I had one connected. no values need to be adjusted for that. There is only one map that you set to the max to stop fuel cut....forgot the name.

Yeah - it's not a code for missing signal, its an actuation code. Not sure what to do with it.

EDIT: made a revised BIN with all stock TCV values. See how that goes.

If your LTFT_I has settles at 8µs then you're golden.

I would reccomend setting LTFT_PL to zero in your .bin. Like I've said before I think it is ineffectual at controlling AFRs on a non-stock motor setup.

I took a look at your log and was unable to recover it, sorry. You should get your wideband hooked up your ECU and send me a long (15minute) drive to go over.

Got the WBO2 hooked up & the formula set (thanks Matt) - so if the weather is accommodating, I will be able to send you a log to review tomorrow :) . Thanks again for all your help with everything!
