normally that NNN ECU which originally had Eu3 map in it should have been loaded with a Eu2 fuel map then suitable for the Eu2 injectors,... i presume that the Dynachip guy was smart enough to do that not to improve the Eu3 map cos if that's the case and the engine is still with the Eu2 injectors that black smoke is normal as they get the wrong amount of fuel due to the wrong fuel map

I would of thought that was done when the ecu was replaced. It never smoked before the remap so I presume the standard map was right for my eu2 injectors.. I presume, I don't actually know!
 
After you set the wastegate try a run with the MAF unplugged too and see if there's any difference compared to it connected
 
yes, your's is on factory setting then, at 11 or even 10 threads left will give it a bit more low end boost, you cantry to 10 and if it goes to overboost back up a bit

Hi mate, just to let you know I've shortened it down to 10 threads showing and took it for a spin once the engine was warm after my commute back from work, up a very steep incline in 4th and I didn't go into overboost so thank you very much for that, I'm fairly sure I can feel a bit of a difference!

Can I ask what make of IC you personally went for in the end?
 
Hi all! I must of had my defender remapped by Mike at Dynachip for a good four years now. It goes well, and has had a dramatic effect on pulling heavy trailers etc.
I fitted a straight through exhaust a while back and this dropped the torque curve a fair amount which was awesome, however I was doing some high mileage and couldn't cope with the drone, so switched back to the old silencer.
However I now do small miles and lots more greenlaning, virtually every weekend really. I've noticed that since the remap it always has a slight puff of diesel black sooty smoke when you boot it, or it's under full load which suggests air/fuel ratio being incorrect.

Would I notice much of a difference if I fitted a full size intercooler now? If so which make? It's fairly confusing and very expensive to go with something that might not be needed... Can anyone share their thoughts... Many thanks.

Ha... I was exactly the same...fitted the straight though pipe, but couldn't live with the drone... even tried Alive Tuning Cherry Bomb straight through pipe, but it still droned too much for comfort.... shame as performance was up and sounded sweet.
