Hdi remap

[Ruan]

Don't forget the HDI has a cold map that restricts it loads before it warms up.

I hate going straight from my '6 to the HDI.

Never knew this but interesting, wonder where theres more info on this. Until what temp does the 'cold map' work?

There isn't a 'cold map'.

There's correction at part throttle to increase injection quantity to overcome the increased internal friction so it'll accelerate at roughly the same rate... There's also correction to many other aspects (Start of injection, railpressure, pilot timing and quantity etc...)

There isn't any function to reduce power when the engine is cold... Nor any sudden switching when things warm up - it's all blended across the entire temperature range. Any lack of power felt is purely down to the fact that the internal friction is higher and the combustion quality isn't as good as the cylinders aren't up to temperature.
