Tuning the tdi

[Vicbitter]

Torque only gets you so far - eventually you're going to need some power as well.

Example.

Jeep Patriot
2.0 litre, DOHC, 16v 4 cylinder, producing 103kW @4000 rpm and 310 N.m @ 1750rpm

Nissan navara d22
3.0 litre, DOHC, 16V 4 cylinder, producing 110kW @ 3400 rpm and 314 N·m @ 2000 rpm.

My brother in law has a d22 and I tell ya, doesnt feel much faster off the mark, but alas does feel faster. (hitting peak kw sooner at 3400?)
BTW, weight would unbelievably be roughly the same!! But his would be heavier.

get chippeduk. its not a generic tune- apparently they read your stock map and cater to your requests when delivering your two additional maps that you get with the stock map (3 maps!!!!). not only from members here, but members on the other site i go to (the club) have given positive reviews about the smoothness of the power delivery, the reliability of the tune etc.

One member on the club (uk) reckons that as far as diesel tuning goes, chippeduk is widely regarded as a good, reliable tuning option (atleast in the uk). apparently, Oettinger isnt reputed as having much diesel experience, and he went on to say that he wouldnt touch revo or giac on his diesel with mine (ding dong).

that, plus im not sure how much logzy is selling is ST3 units for, but they WERE 800aud for two maps plus stock map.

good luck!

thats what im gonna get when my warranty winds down a little. AFTER suspension work, of course.

Power is a by-product of torque. They're directly related. Can't have one without the other.

Actually you can as power is a calculation from revs and torque. F1 engine doesn't have lot of torque, but still it produces high power with very high rev area.

Acceleration depends on weight and on average power within gear. Torque has nothing to do with it.

VWs tend to have more power than told by the factory. 103kW engine has usually something between 108-112kW.

This discussion can get very technical very quickly.

To be pedantic, you can have torque without any power at all - as long as there is no rotation there is no work being done. Think trying to undo a very tight large bolt - you can apply a lot of torque, but until it moves you haven't produced any power (despite what the sweat on your forehead is trying to tell you). So you can't have power without both torque and rotation (revs).

To actually make a car go faster (or up a hill) you must have power (power is the ability to do work, moving a car faster is work).

What most people mean when they talk torque vs power is either :

I like more low rev torque because it allows me to accelerate (or go up a hill) without needing to change gears.

I like more power because it allows me to accelerate faster.

There has been (and will continue to be) lots of discussion about the two preferences.
