Ian,

Ian,

a n00b question: what does 'torque-based' strategy mean?

torque-based engine control is an architecture which uses a central torque demand variable to control the regulating qualities.

This torque demand variable is the result of the coordination of all torque requests throughout the vehicle Discovery 5 td6 HSE Stornoway Gray Outback Engineering Limited Edition

UPDATE –

This is for the IRB410 conversion. No other modifications are required other than the new software.

The second stage of tuning is already in progress… just over 460nm at the flywheel (and 150bhp).

And there is a 3rd and 4th level…


Modifications to the air intake and exhaust will be required….

Hi Ian,

Been following the posts with great interest

Do you have any graphs for stage one - similer to the first one to show the torque and BHP improvement

Also, what other mods will be needed for stage 2 or will it just be software and is there a graph for that

Any news or info on cost for stage 2 please  Gas, Grass Or Ass - Nobody Rides For Free

"UNDERSTEER" ----is when you hit the fence with the front of the car.
"OVERSTEER" ------is when you hit the fence with the rear of the car.
"HORSEPOWER" ----is how fast you hit the fence.
"TORQUE" -----------is how far you take the fence with you.

Apologies for the delay - here are the final dyno charts for the IRB410

Blue lines are final curves, red are original. Upper is torque, lower curve is power.

Has anyone had their 2.2 remapped yet, by IRB or anyone else. If so any good? A review of the remap would be great.

Tell you at the weekend when I get ours back
