Chipping Diesels

[Solo Man]

E39 530d Auto. Have been reading up on chipping/tuning diesels. Amazing the amount of torque to be gained by going this route. Apparantly, consumption is also usually better. In my case where i stick to the speed limit like glue, i should get better consumption after chipping. Quotes vary from about R3500 to R5000, some even with dyno tests/results. My biggest issue with gaining all this torque is the auto gearbox on my car. I am not sure if it can handle the extra torque, as it seems these gearboxes were designed to really only handle the max torque of the standard motor, which is about 410nm, although the 530d's from about 2001 is supposed to have a slightly stronger gearbox rated at about 490nm torque. I have taken the numbers off the gearbox plate but they do not seem to match any of the GM gearbox numbers on the internet. The info is: GM Strasbourg, Made in France??? 3GYP
7520853 and 96024854 and P29-0738110 The build date to my car is 10/2002. Anyone able to tell me if i have the 490nm torque gearbox or 410, will really appreciate it.

The "G" on your gearbox (3"G"YP) means you have the 340nm version (the 390nm one has a "Z"). We in SA never got the 142kW/410nm car, only the 135/390nm version (check your manual for SA specs.) Which means you are already quite a bit over the rating of the gearbox, and I would not recommend chipping her.

I'm pretty sure my old 2002 530d was the 142kw/410nm version :dunno:

P1000, checked my handbook, says 142kw/410nm, but i assume this booklet was printed elsewhere cause it is also mentioning the 525d as well as 530d touring. How certain are you about your facts as it is quite an eye opener to suddenly hear that your 410nm engine only develops 390nm. Ouch!!

No, we got an "SA" spec. it was some kind of supplement to the manual. I was also convinced mine was 142kw, being a 2003 model, but alas, only 135kw as confirmed by the G on the gearbox...
