1.5dci Delphi DCM1.2 decreasing IQ on warm - what`s limiting

Postby carlo80 » Sun Jul 14, 2024 11:51 am

Hi,

I tuned stage 2 ( bigger turbo ) 1.5dci to about (125-130) - from 85PS .
When i logged WOT during winter I was getting IQ 52mg to across 4krpm.
Nowadays during summer - after short even drive - max IQ went on WOT to 47mg to 4krpm .

Any limiting map or correction comes to your mind ?
On logs everything is ok - all maps on fuel delivery is OK and nothing is limiting me , however real IQ FUEL RAW is decreasing , something is limiting and decreasing IQ ...

IAT is about 27deg C
Fuel temp is about 46-50 degr C
Water temp is about 80 degr C
EOT_OIL_Temp is about 80 degr C. ( Couldnt find any maps on OIL temp on Delphi damos?! )

What map or correction comes to your mind ?
I changed before maps ( during winter ) and worked very good , now is limiting something.

PS. IS there sensor of OIL temperature in 1.5dci delphi ? I didnt know that. I cant find any maps on OIL temperature on delphi damos.
