I am new to the Engine tuning subject, not really looking to make it any sort of a professional career, just want to know how the engines are tuned up - Cutting the long story short, I have bought my Civic 2.2 diesel a year ago - great car btw - anyway, the seller mentioned that he had the engine tuned with a Celtic tuning stage 3, upgraded clutch, etc - didn't pay any attention to it at that time, but now I am looking for some new hobby and studying ECU tuning seems like a complex enough subject to keep me away from the x-box:) I have decided to download the tuned map from my ecu and by comparing it with an OEM map from my mates civic find out which values were altered and most importantly why and what is the result of changing them - loads of reading, but so far I really like it - started to understand basics, the relations between various components and settings - stuff is complicated, but if taken on slowly it makes a perfect sense. Joining this community I am hoping to get some tips and help in understanding the subject.

Best Regards, Ark.
