Hondata

selecting "use MAP to determine WOT" also gets your AFRs at higher loads in check. so by default at WOT, the ECU is aiming for a 14.7AFR. Honda has these cars run in closed loop at WOT, which I guess is safe on these new direct injection turbos, but you won't see a good amount of engine power so the...

Just to update this thread. I finished up with my tune on my car. Here are my thoughts. 1. +9psi(or 24psi) tune is a misnomer. For us CVT users running on 92octane(100RON.) In reality, you would like to add +9psi(24psi) from 4000rpm upto 5500rpm only and quickly drop it to +6(21psi) upto redline or...

Can somebody help me take a look on my datalog of 40minutes of drive. I've look around forums and many said that we should ignore the knock count value and focus on knock control instead. But the knock count i've encounted still bothering me. 50k km now and i plan to keep this car for a long time, ...

I actually have the opposite happening, as you can see in this datalog from 2:40-3:00, I am stopped after moving and my car idles extremely rich for a good 20 seconds.
is that an AFM problem? should i watch at what AFM.v the car idles at and pull fuel from that range?

Here's a datalog that shows t.pedal is at 96% while t.plate is at 101%. Seems normal. TPEDALdata.fpdl Hondata, anyway to change the throttle pedal to plate ratio? "improve throttle response" seems too sensitive, while having this mod disabled seems to make the pedal too fluffy. would love an in-betw...

I noticed this too on your tune gtfrede

Are you seeing the same on your tune? I think I have seen this happen with mine.

my t.pedal only makes it to 96% as well, but t.plate opens 100-101%. so it's as throttled as it can be at 96%.

Yes. Proceed the same way. When happy with the s trim; re-enable l trim. I am personally going to limit mine to 5% +/-. All this would help with is the tune remaining close to optimal should the oxygen sensor start failing or if an exhaust leak would develop later on. Would not let the trims get co...

That is exactly what I did.

Should I continue adjusting my AFM values based on what I see with L.TRIM disabled?

Basically it keeps the global fueling adjustment for closed loop not functioning while you calibrate the afm table. You would want to dedicate a full day to doing this. Not something I would do right before a commute to work or anything as your limiting the ecu's compensating ability. Gotcha, what ...

its under closed loop parameters. limit the long term trim percentage to 0%. I did mine for the last week or so to see what if any effect it had and am about to enable it again. Didnt change much of anything . Just a faster way to calibrate afm when starting from scratch. Thanks man, what makes it ...

Yes , but only if your are tuning the AFM. If i have been tuning my AFMs based on my short term trim trends (AFM.v X short term %), should I make the minimum and maximum for long term 0%? What would this do to the way the car feels and drives? and would I also want to limit short term in any way?

Allow me to rephrase. Should we limit the long term trim percentage to zero?

How do you adjust Long Term trim limits without affecting short term?

I've been adjusting my AFMs based on my short term trim results, and my long term trim moves too when I make that adjustment.

I was getting pretty decent knock counts running the 6PSI tune with no adjustments made to it. Between 12 and 19 knock counts over 50 minutes of driving, 95% of which were being recorded in the same range on the ignition table. Knock control was responding to every single one of them, sometimes gett...
