Hello everyone, I finally made my car work properly at idle and wanted to continue to tune it up further. The problem I have is that after accelerating (doesn’t matter the amount) the car firstly loses some rpm and then it increases. Is it an Acc enrichment problem? Thank you! ---

U should also fix ur knock sensor settings…u have permanantely a ignition retard by 15 by knock. And here: ![image](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/6/6f5e63bc89c695c02fc41fffdcd3ac57c89e68c6.png) U can try Enable full group inj…this will help with ur issue. Then i would paly with Acc sustain rate…i learned that there was something buggy in old SW and i set it to 0. But i think full group will help a lot. ---
