So unsure, does moving the jumper from 1 to 2 make a difference? Or does the fine tuning jumpers make the difference.

I don’t want to mess with it to much, and then cause a problem.

As you have the red dot your settings are as per the left description, map 1 for economy and low end torque, map 2 for maximum power.

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?

Yes they should both have the same low end torque but map 2 adds extra fuel rail pressure higher up, which should mean more fuel use and shorter life expectancy for the fuel rail and/or injectors.

These boxes increase power by increasing rail pressure, whether the cheap CR tech or more expensive Pro version.

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?

Hi
I Just want to make a second opinion about this tuning box CHIP TUNING BOX BMW 3 320D 163 cv THEITALIANBOX REMAPPING ECU..does anybody tried this product before? cheers

Save your money and either get a DTUK 3 channel box or a proper remap

All the info is in the thread mate.

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.

Right okay thank you, well I think I'm more scared that a stage 1 remap may bring problems to the engine etc. That's what's putting me off a remap.

Go with a reputable tuner and you should be fine. If anything, the additional strain a tuning box puts on the fuel pump (as evidenced by some of the fuel cut issues talked about in this thread) is worse than anything a well written remap will give you.

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!
