Blowin' a bit of smoke!

If you have ever seen how much smoke mine blows you'll know it's normal

Pearce - no spark plugs on a diesel engine

Yes- plenty you can do to up the power, but have a search and read around the forums - its all been discussed at length before.

Your tuning box works by misinforming the ECU about the qty of air the engine is recieving (or the air temp - same effect anyway) and thus gets the ECU to inject more fuel. This gives you more power on a diesel up to a point, but its a very cheap and nasty way to do it and is also why you have a disproportionate increase in smoke for hte amount of power gained.

I have a tune on my skoda thats gained me about 20kW and 50Nm and it smokes less than with the standard tune - because the boost, injection timing and fuelling maps have been altered.

Check out all the stickies for some more diesel reading.

Oh god I can't believe I wrote that.

Get rid of that box.
Just do it, they're awful. Get a proper tuner onto your car.

Hey mate, I want to do my EGR soon, maybe organise to do it some weekend together?

**Pearce** · 16-05-2013, 06:01 PM

Haha yeah sounds like a plan. I have a couple of friends that will help so see how we go. I'll let you know!

Hey man I went ahead and bought the darkside developments Egr delete.

And have since installed it, (was a pain to remove the Egr and fit new one mostly die to the Egr cooler pipe being in the way, and I have fat hands haha)

But warning, if you do this you will get a engine light "emissions garage" which is caused by the removal of the original Egr which has a flap inside too a straight pipe from dark side.
But I have been told that with a tune this can be tuned out.

My car has 992xx Kms and was pretty filthy. I didn't remove my inlet due to lack of daylight but I cleaned with about 4 rags as far as I could while It was still on.

It is worth doing but make sure you have Allen keys that are under 4-5 inches in lenth (I hade longer ones around 6inch and it just made everything a real pain in the ass!)

Haven't had occasion to look at one, but in a tight spot I've found the best way is often to cut a short length off an Allen key, then use a socket and ratchet (or a ratchet spanner.)
