CR or PD engine ?

Good remap in tdi 140 and you see tdi 170 in the mirror.

Best regards

i had done a few of them

[alexs307]

by using 2 different ecu the first one use a bosch EDC16 and the seconde use a siemens ecu

First one is Bosch EDC16, second one is Bosch EDC17, not Siemens.
170HP Pumpe Duse version has Siemens ECU, the CR version has Bosch. Your Q5 file is from Bosch ecu.

In my opinion PD's will remain the most "tuneable" engines, if I may say so. Can't figure out why VAG got rid of them and switched to CR...maybe exhaust emissions too high to cope with new Euro5 regulations?

[lolooo1981]

And for siemens TDI there is a few different type of ecu inside.Gain in siemens 170 is good and for CR ?

Common rail injection pressures have now surpassed pd ones, look at max pressure in gen1, 2, 3, etc common rail then pd. Pds load the cam an awful lot as well. Higher pressure means better atomization better efficiency etc, thats what I think anyway.
grinovsky compare the torque/fuel at the rpm where it makes peak hp not torque, peak torque figures mean nothing re speed/acceleration, most standard diesel family saloons make a higher peak torque figure than an f1 car!
