This is my new remap.

I have logged my runs - acceleration 0-100 km/h and acceleration in 4th gear...
Stock acceleration for this car is 10.3 seconds...and in my logs..it is same !? :) I suppose that my shifting is not fast enough (as I try to save gearbog and clutch) and maybe delay in MES logging...so i suppose that this remap should do under 10 seconds.
However, I can see some boost pressures that are higher than SVBL...but everything else looks OK to me. Can this be dangerous?

Thanks!

Hi mate,
At first glance,
IQ /temp is limited to 75mg at 3000RPM(same IQ as logs),but you ask 85mg onSmoke Limiter map.Also Torque limiter have max. value for 75mg of diesel.??DW is tuned with small values at 80% of throttle.
On N75 map,have modified only last column,X axe only for 70mg of diesel.
What diesel amount do you want to inject?
amount from TL,from SL,DW,Turbo map X axe??from IQ/TEMP.???I think you should bring them all to the correct value.

Hi, thanks for review!

Yes, all limiters are done like you say; smoke limiter is highest and it just preventing AFR to be too rich; it is not "request" map. Temp limiter is modified to be just a little bit over TL, which (i think) should be lowest value...so amount in TL are amounts that I want to inject. I have just increase this values by 25%, little less at low RPMs to save clutch. Maybe can bee increased more, but don't know if clutch would handle it. I still didn't manage to calculate torque based on fuel injection quantity and RPMs...so don't know how high with fuel can go.

Reason for small values in 80% of throttle is because I want to reach increase power only when put throttle to full. This map should be more economical and powerfull only on full throttle.

On N75 map...yes...there is only 70mg of diesel in last column...but I think that this should work OK. Do ECU calculate values for duty cycle if more fuel of 70mg is injected or it just takes value in last column?

Best regards,
S.

Hi mate,
You say-"Reason for small values in 80% of throttle is because I want to reach increase power only when put throttle to full. This map should be more economical and powerfull only on full throttle."and what can do turbo ??must response very quickly , but in reality isn't so.TL,SL, Turbo map,DW,IQ/temp are involved in calcul;ation of IQ amount.Can't have up to 80% throttle an economic engine and suddenly at 100% throttle more more power,is just a wish,that does not match with reality.Economy and performance are words are mutually exclusive.But is only my opinion.

Well...everybody have opinion...that is good and because of that we are here :) ... and all we learn something from others opinions.

There is turbo map that goes to 52 mm^3 and other that goes to 65mm^3, in my remap that second one goes to 70 mm^3. I'm not sure, but I think that first map is related to "normal driving conditions" or "economical driving", and second one is for "hard driving conditions". Not sure for this...don't actually know when is selected one map and when other. Maybe selection depends on water temperature or other parameter...don't know. In assumption that first turbo map is related to economical driving, or low IQ request, I have raised turbo pressure in all values. This I can see when driving in very little throttle...car is going much easier and reacts on small throttle increase much more than before remap. When I put pedal to the metal, I think that second turbo map is selected, and because I put full throttle, max IQ is requested. So, IQ is increased, boost is already increased by previous map and now second map is increasing boost...and IQ is calculated by intake air quantity and smoke limiter but limited by TL if in smoke limiter is allowed higher IQ for current intake air quantity.

This is my opinion...but may be wrong, so I am here to somebody disagrees with me and point me what I'm doing wrong and what should I do to make it right.
