Mercedes W204 2.2 CDI CRD.11 Stage1 and black smoke puffs
Hi guys, i have a mercedes W204 personal car, made a stage 1, wrote file on bench, and did EGR off.
Car has some little black smoke puffs even if accelerate on stationary. Made stage pretty light, I attached files, just free some torque limiters, little rail increase and that's it. Measuring airmass on idle , about 550 to 600 mg/stroke on full load about 1.6 bar boost and 1200 to 1300 mg air having big cylinders. DPF is still on car, but i have little black puffs, what can cause this ? Attached is the original and MOD file if you want to check, but remap is pretty light. Changed airfilter, oil and all filters. |
