I’d recommend map 1, then play with the adjustments. No point in position 1 & 2, but 3, 4 or 5 should all be tried. |

I just swap between Map 1 and Position 5, and then Map 2 and Postion 5.
Map 2 postion 5 feels slightly better. There seems to be no difference in low end torque between the maps. I guess Postion 5 is the maximum fine tune/power for the given Map? The higher model boxes seem easier to understand, and give different gains. Oddly people don’t try them on maximum fine tune on each different map? Luke |

I believe the Pro version provides more aggressive states of tune and one of the reasons those of us who ran them previously stayed away from maximum settings was due to fuel cut issues. We all experience instances where the car would cut or limit power due to the box asking too much of the injectors and fuel pump as Teaston alludes to above. One of many reasons I went for a remap, but you should be ok if you're not pushing things too much.

Thanks.
I did look at changing it for a CR2 box, or the Pro. But for £90 its working fine, no issues running it on max. I wouldnt want to have a Pro box, and not having it on full, would seem you are better with a CR1/2 box on max, than a Pro box on medium? Luke |

In a nutshell, all diesel tuning boxes work by fooling the ECU into increasing fuel rail pressure thereby injecting more fuel into the cylinders. On a diesel, more fuel = more power. The more advanced boxes might alter boost pressure and vary the amount they increase rail pressure at any given point in the Rev range to deliver a smoother tune. A remap can alter several other parameters, such as injector timing, to achieve increase in power and alter the characteristics of power delivery. Now that remapping can be done over OBD using a laptop, there's little to recommend a tuning box instead unless you're still under warranty (tuning boxes will be harder to detect, though not impossible) or running a lease car or something.

I went tuning box to remap and the engine was definitely a lot happier with the remap. If you're really worried about something going pop, I'd avoid either!
