Hello fellow mechanics!

After reading several technical articles, including one about power boxes or chip tuning, I started thinking about what modifications I might want to make to my ASZ engine, and what I definitely don't want to do.

The article about delayed Northwest Airlines (NWA) integration includes a diagram showing the torque curve.
After reviewing the numerical values in the ventilation report again, I noticed how 'unharmonious' the ventilation actually is in the air conditioning system.
Sure, it delivers good torque at 2000 RPM, but it drops by over 40 Nm during the next 1000 RPM.
For example, when comparing the ATD or AXR engines, each with 100 horsepower, the torque curve doesn't drop off as quickly.

Now, my question is:

Can the torque curve of the ASZ engine be adjusted so that the torque output doesn't drop off as much?
It's not about increasing the torque at 2000 RPM, but rather about maintaining the 310 Nm of torque for a longer period, so that it gradually decreases only from, for example, 2600 RPM onwards.

Is this possible, and what technical problems might such a tuning process entail? Or, would it be less stressful for the engine than increasing the torque at 2000 RPM to, for example, 350 Nm, which would result in a sustained value above 300 Nm?

If the tuning I described is possible, I would also like to know who has experience with it and what the cost would be. icon_smile.gif

Greetings.

Calvin.

You seem to be looking for specific chip tuning solutions rather than technical advice. Try this forum: http://www.chiptuningforum.com/

They will definitely customize it to your liking (if you do some research, you'll quickly figure out who really knows what they're doing and who doesn't).
