10:20 to 11:00 is a specific example where I'm in column 9 13.07afr requested target lambda low and afr is holding 14.7afr. 39% throttle. Why is it holding 14.7 instead of requested? In attached data log above. It is weird because you can see the afr richen up after a few seconds.

Been a busy week...

I am guessing there is a setting somewhere I am missing so closed loop will go off my target lambda and wot lambda tables. Calibration file and datalog attached. Been street tuning over the last 4 months. Car was "tuned" by a shop in Atlanta originally and had all sorts of ...

2009 Honda civic Si with Flashpro v4.5

Is it possible to run open loop and go off fuel tables on low cam? I am boosted and have had to pull a bunch of timing on low cam to keep from knocking while climbing steep grade. Closed loop is pulling 20% fuel keeping afr at 14.7. I have the target lambda low afr 12.5 in column 9, but closed loop ...

I guess I might as well adjust my low cam fueling resolution as well and get to using the autotune feature again. I am right better resolution closer columns will increase the ability to get fueling spot on and lower short term fueling, yes? Or is it not worth it?

As I was typing I realized I can increase resolution for fueling since I am maxed out at 8 psi on my wastegate spring. Score!

I have show all columns under options selected and all 20 are there in fueling, just not WOT lambda adjust.

06-11 8th gen us. 09 specifically. Started with the DW1000cc injector basemap and the WOT low and high only show 10 columns. I right clicked but it won't let me add any columns like I could in low/high fueling. I have column 10 ".2" set to 11.64 afr so anything above that will go off column 10 I am ...

How do I add boosted columns to the WOT Lambda adjustment table? I'm sure there is a way... I'm on the 1000cc DW injector starting calibration.

My current calibration after autotuning low cam fuel...

I have spent the last 3 nights methodically using auto tune on the low cam with vtec set to 7k. Started at 30 cam angle with autotune set to 4 weighted cells and 10% max change from basemap. Drove around town and highway making sure to hit all columns from to 1k to 6.5k rpm. Looked over datalog and ...

Alright, got my injector opening times adjusted and I feel I got close. Went for a short drive and I am blown away how much low rpm power I have locked on 30 degree cam angle compared to the "tune" I had. Lots of work to be done still. Can someone take a look at my calibration and the datalog and ...

On my 5th 8th gen Si. 1st boosted k20. Purchased it already boosted and "tuned" on dyno. Contacted the tuner to ask if he would unlock the tune for me and he said no which I understand. I have 3 years experience with FP street tuning my NA K20's from watching all the Hondata YT videos and any others ...

Stock flywheel with fx400 clutch. Throwout bearing is on the loud side compared to my 4 previous Si's but I'm guessing stage 4 TO bearing? Or whoever installed it didn't use high temp grease on the input shaft. Going to pull the trans inspection cover and see how it looks and check for up/down ...

I purchased my 5th 8th gen Si! 09 FG2 with 93k miles and my first forced induction k20. 62/62 turbo. Tune is not bad. afr's great under full throttle. Having an issue when coming to a stop and pushing in clutch engine almost stalls. Only thing I could find that may be the culprit is in settings ...
