Hondata

Yes, stock honda.

i recorded 60 sec of open loop, and about 30 sec of closed, didnt want to have the car running that way.

Why cant i adjust the short fuel trim and other stuff in the new version???

I have now tried with the latest version, started the car first time today and in closed loop, starting af was 13-14 for some seconds, i went down to 14.7 -15 and stayed there for like 5 sec and then Went right out of scale, 0.2 v showing from o2. i then put the car in open loop and the af Went ...

is this a known error in previous versions? yes at startup its about 3.79v then when it warms up in a minute it starts to decrease voltage until 0.2 0.1 and it starts to lean out.¨

BUT! even with the short term fuel trim set to zero percent i will go lean on me, have you ever seen this before?

I ...

Like this?

It is the same calibration for Open and closed

The Only thing i do is change to closed loop and upload. Does the fuel tables change when i do this?

I dont understand?

The calibration i posted first is the actual calibration that i use right now, i have only tested with different short fuel trims and so on.

But is it even possible that the af Changes when it is perfect in open loop, then i change to closed loop and set short fuel trim to 0%?

You mean this?



narrowband target voltage is 0.51.

i have tried with short fuel trim at 10% 1% 0% no difference... i cant understand whats wrong.

Its the same calibration for closed and Open.

Thanks! Sure, ill try.

the recording are not very long, did it for my tuner yesterday but he didnt know the answer to this riddle...

But how can the open loop be fine, and then closed go super lean with 0-0% short fuel trim? Is this even possible?

Im not sure if the closed loop recording is with ...

Hi, my first post here, im from Sweden so the grammar might be slightly off!

This saturday i tuned my built b16a2 at my local tuner, Everything Went fine but after the tuning was complete (In open loop) it would run very very lean in closed loop using stock narrow band o2 sensor.

I have a aem uego ...
