Help with XML

[den_163]

Hello!
When tuning, the car ran into such a problem. Firmware version KS-Mod 1.03. Extended injectors were installed and the intake was reworked. When resetting the gas pedal, the mixture is enriched to AFR10, and only then it becomes depleted.
I was told that you need to edit the cards decel enrichment.
Help please, need XML decel enrichment .
Can anyone have?
Or tell me where to get it.
Thank you

Sound like you need to change the injector size and probably something else but I can't remember what. @Confused @foxdie will probably know.

I corrected the injectors. AFR with cards coincides.

[Confused]

I'm not quite sure I completely understand Do you have access to EvoScan and can you get & upload some logs which show the issue you are experiencing?


When you release the accelerator pedal, the AFR goes rich briefly, then the injectors shut off and it goes fully lean, until the revs have dropped?

I filmed the video, but I can not attach it here.
How do I show the video?

YouTube will be best for the video

I presume you are at cruise driving down the road you lift off the accelerator AFR goes rich and then goes lean. Then if you stay off the accelerator the AFR comes back to normal.

When you lift completely off the accelerator the injectors get switch off completely by the ECU so you see the lean event. Either you press the accelerator again and AFR returns to normal or you keep you foot off the accelerator and AFR returns to normal.


By the way you review counter does not work.
It could be you IFS (ignition fail sensor) on the top of the front rocker cover.

When lift completely off the accelerator, the AFR should be immediately depleted (instantly goes lean). Right ?


But for me first AFR goes rich and then goes lean.

I guess my English is not good. SORRY

I seem to remember this coming before in forums some where.

I don't have my mtx-l on my black vr4 it is on my silver on and that has no engine at the moment. So i can't test it for you.

When was the last time you calibrated you wideband. Needs doing at least every 6 month on mtx-l. I usually do it every 3 months.

I don't think mine goes instantly lean either. I'll check next time I go out in mine

[Amonlym]

Not on a wideband, but just the other day I was logging AFR from the ECU, I will check and see what the snap response looked like there. I will reply again if I can find anything helpful.

[den_163]

If you check, it will be very good. Thank you !

I just started tuning, so it's too early to calibrate

I have the aem wideband and when I let off the throttle completely it goes rich 11 and 12’s then full lean - - - - on the gauge. Just like in your video.

[rajvr497]

Running abit rich then completely lean sound normal to me after letting off the throttle

[Amonlym]

hard to read clearly from stock o2, but it does show a long lean period after throttle lift and a rich spike at lift-off so I would agree with the others and say this seems normal.

Hello !
I could not answer for a long time.
Thank you all for your participation.
