im using direct through the obd2 pass-through. i think it is right. i can easily tell the car was running like shit with the high AFRs it was recording. runs like a raped ape at 12.5 WOT.

probably used values from a old file that didnt have the VE quite dialed in therefore calculated dynamic was off?

id be curious to hear his opinion.

changed files on my drive. GTO Tunes - Google Drive

scan file i used to get the newest dynamic airflow numbers from : OL WB VE Tuning 11S2_b
made MAF WB Tuning Edit 12 tune file
then the following scan file : MAF12. seems to be much more in-line with AFRs

well since i re-enabled STFT/LTFT/DFCO/CFCO i need to revisit something in the tune. occasionally when cruising (only noticed at ~40mph and ~50mph so far) that it will go open loop and a little lean (16) and the trims arent doing anything. leaning towards dfco coming into play? but it doesnt go away when i press the gas or change gears. only seems to reset if i push the clutch in for a bit or change speed enough

Does it do it often? Ive now recorded it multiple times. Itll even give an afr command of 16ish when it happens so im not crazy and getting something way off.

The e40 ecm doesnt have some sort of lean cruise function does it?
it will run every so often. you can turn it off in the tune, but i don't remember if it effects one of the emissions readiness monitors from reporting completed.

Yeah i saw it. I didnt get my edit in fast enough apparently^

No emissions here so thats not an issue. We dont even have annual inspections.

Edit: seems to have fixed the issue. Thanks for the tip

Raised all 4 corners and started to prepare for pulling the transmission. Only got the driveshaft out tonight but with the dss carbon 1 piece i didnt have to drop the exhaust at least.

making this post for myself but maybe itll help anyone else starting out.

Wideband VE Tuning:

Engine - Airflow - Dynamic - Dynamic Airflow : High RPM Disable --> 8000rpm
Engine - Airflow - Dynamic - Dynamic Airflow : High RPM Re-enable --> 7900rpm

Engine - Fuel - Oxygen Sensors - Monitoring : O2 Readiness ECT --> 284 (whole table)
Engine - Fuel - Open Loop/Base --> All tables to 1
Engine - Fuel - Power Enrich - Power Enrichment : EQ Ratio --> table to 1.176 for NA applications (12.5 afr)
Engine - Fuel - Temperature Control - Catalyst Protection : COT --> disable
Engine - Fuel - Cutoff, DFCO - Deceleration Fuel Cutoff : Enable ECT --> 284
Engine - Fuel - Cutoff, DFCO - Deceleration Fuel Cutoff : Disable ECT --> 283

Engine Diag - P0101 --> MIL on first Error
Engine Diag - P0102 --> MIL on first Error
Engine Diag - P0103 --> MIL on first Error
Engine Diag - MAF Frequency Fail High --> 1hz
Engine Diag - MAF Frequency Fail Low --> 0hz


Wideband MAF Tuning:

Engine Diag - P0103 --> MIL on second Error (stock setting)
Engine Diag - MAF Frequency Fail High --> 13500hz (stock setting)
Engine Diag - MAF Frequency Fail Low --> 10hz (stock setting)

for closed loop STFT tuning leave these factory setting:
Engine - Fuel - Oxygen Sensors : ECT vs Startup ECT

Received the LFP dual pass heat exchanger today, feels and looks nice.

i personally wouldnt buy from LFP again though. originally "bought" the afco but they called later to explain those would be quite a bit later till in-stock, their branded hx was in-stock now. theyd refund the difference ($70 according to their website) if i was ok with the change. i get a refund for $60 and they sent it via paypal goods so theres another few dollars i pay. doesnt look like im getting the refund for the other $10 either. just not really the way id expect that to be handled.

I need to figure out how to mount it, theres no tabs at all

Debating running the lfp and maggie hx in series or picking up a duspeed as well

Just noticed your build thread here and looks great and familiar and your going to love the torque. I purchased the Frozen hx first and decided it wasn't for me after getting almost done. I also have the LFP now and just getting through this myself along with a Duspeed install. I was planning to post up another thread - you can give me some better ideas again...
