No power in 1st or 2nd

Torque limiting to prevent killing your clutch more likely...  Plus it probably has ESP which kills torque and won't let you wheel spin anyway lol.

Why would it limit it in 1st/2nd to not kill your clutch You'd want that in higher gears to prevent clutch raping. Seen some with limitation when the clutch is depressed to stop you putting full torque through a depressed/slipping clutch though.

It's partially wheelyspins prevention and also to make the engine feel less breathless lower gears, otherwise you get a huge surge of torque then it goes breathless past 3500rpm. If the torque doesn't drop hugely, it persuades you to rev the engine harder, feeling like the engine isn't horribly weak at high RPM...

You tend to feel changes in torque, rather than horsepower, so when diesels produce all their torque at 2k and from thereon are only ever reducing in torque, they feel like they're getting weaker at higher RPMs, really they're not, they're pulling just as hard, but if an engine produced 150hp from 1000-5000rpm, it'd feel like it gets weaker the more you revved it.



As you can see, making it's peak power at 3900rpm - but torque is only ever falling from 2k on, but I can assure you it doesn't feel like the peak power is at 4k - in 1st/2nd it sure does though - it seems to want to really rev!

Sorry for the thread hijack - in response to whether anyone has pissed with the gear dependent torque limitation, nah, I doubt anyone has tbh... Need to get diagnostics on it, actually log what's going on... What's your ECU number? (Look on ECU, should be a number starting 0 280 0xx xxx - that's the one)...
