Title: Pops and bangs vw golf 1.4 16v BCA ME7.5.10 doesn't work help Post by: Thom on June 05, 2020, 12:41:09 PM Can anyone tell me what iam doing wrong?
Changed KFZW and KFZW2 map first 2 rows from about 4600 rpm to 6000 to a value of -18 to -8. This works on my 1.8t but on the 1.4 it doesn't work. It makes very small pops. Do i have to edit fuelcut maybe? Who can help me?

Do i have to edit fuelcut maybe? Who can help me? Search the thread: "Overrun, Flames, Gargle, Pop" its got tons of Info. It looks long but trust me its worth it. Generally I think first 4 pages you will find what you need for your particular ECU.

i did read this entire topic but from what i also learned a lot of users didnt change kfzw. infact when i changed all timing maps (for pops and bangs) car didnt drowe smooth under really low load , when setting back kfwz to original this efect was gone.

I didn't change KFZW on 1.8T Try negative values on KFZWMN such as -20, -30. I suppose the car also has KFZWOP map, recommended is current value minus 20. But i tried with negative values such as -10, -20 for hard bangs. Use KFTVSA to delay fuel cut. |
