Hello everyone,

I am newbie for chip tuning. I have been learning for 2 months. I decided to start to learn with ECU's which are Bosch EDC series . I read many topics in this forum. However I have some question about EDC16 and EDC17. Because there are videos about tuning of EDC15 but not 16 and 17. EDC16 and EDC17 are different from EDC15. I am able to find maps in EDC series. I am not sure that is my kp file (mappack) enough for tuning.

My attachment has ori file, mappack and stage 1 project. Of course, tuning file is not good. I did not work with percentage increase. Could anybody look to my file and could you advice me about mappack and the tuned file please?

Sorry for my english.

Just on 2 minutes look.
Mappack is OK, but tuned file not.
DW -Why need 30% intorque increase at 5300rpm???
Smoke limiter-percent tune 19%-why need 19% on almost all maps values???
Boost map, why need 14% increase at 800rpm?????
Boost limiter-why need at 860mBar atm pressure 2300mBar turbo pressure?-will kill your turbo if you drive on high mountains.
Duration- you ask 1deg.CRK but that is not enough, because as you can see for 5mg fuel need around 2,5degCRK.Same for SOI maps
I think you must rework your file,better keep maps values on 5200rpm as stock values.Is just an old Diesel.

Thanks for replying my message. I am trying to learn.

DW -Why need 30% intorque increase at 5300rpm??? IS the other increases in other engine speed values good or enough? Only is there a problem in 5300rpm?

Smoke limiter-percent tune 19%-why need 19% on almost all maps values??? Because SVBL is 2350 mbars and I calculated to Injection Quantity limit of my file. 2350*0,475=1116 mg/stroke. I choice stoic value of new IQ value to 18,0. And new IQ limit 62 mg/stroke. Old IQ limit was 52 mg/stroke and neccessary increase was %19 to reach value 62 mg/stroke.

Boost map, why need 14% increase at 800rpm????? Because of my SVBL that is 2350. I thought it is safe limit for tuning. And I changed all x axis values( IQ 45 to 62)

Boost limiter-why need at 860mBar atm pressure 2300mBar turbo pressure?-will kill your turbo if you drive on high mountains. Torque map y axis starts with 930 mbars so I thought that pressure lost before map sensor is 90 mbar and 860 mbar is not mountain.

You are right about SOI and Duration maps but I have a question about this. SOI limit is 28 Crank angle in SOI Limiter map.

I will rework.

Generally good tune ! ;) ;)

Thank you for your reply. Could you explain more? Which maps did you like?
What is your opinions about:
- New Injection Quantity value (62 mg/stroke) is enough or too much?
- Boost map is enough without incresing?
- How many degree should add to values of SOI and Duration maps?
Thank you in advance.

I see many tuners these day, today they are a noob and tomorrow they are a professional at tuning and supplying top quality files :roll:

So shouldn't we learn? What did you mean? It may be difficult today but it is possible in the future. Why not improve ourselves?
Nevertheless, thanks for your comment.
