Hi Guys,
As you well know I´m not a native speaker so I will try to express myself the best I can do, but I do apologize for "molesting" your language :(
The problem is not putting air in to it...is putting air without the MAF to cut fuel injection...Quote:

Thats when I made exacty the same thing as bennyIIA
Well, from this moment the ECU in higher RPM started to cut fuel. I then make some readings with the nanocom and came to the conclusion that it has something to do with the maf sensor. by "reading the books" I realised that MAF sensor works with a maximum 4,9v. When you send much more air into it, this V value will raise above that value and the ECU will cut the fuel from your car . The bypass solution was an attempt to skip some of the air from the MAF directly in to the turbo so that it could not reach the MAF Sensor.Quote:

1 - unpluge the maf sensor - The ECU will receive default data and the car will work perfectely - apart from the fact that when you turn your engine one, it will take about 10sec till you have a full response from the acelerator :) ) (as Hamish 71 said :) )
2 - IRB Developments - Diesel Tuning and More (already suggested by bennyIIA) (Ian got there first. Congratulations:) We, at td5inside, have a huge respect for Ian´s work and know that this was not an easy achieve. We must give him all the credits. We will not copy his product. From this moment when we need the clever box we will buy it from him)
On VNT turbo the problem is the same. We look in to get more air in to the turbo. But when we do that the MAF is simply not ready and cuts fuel injection...and, it´s the same story all over again.
For the record, I still think that with stock turbo and stock air system we can get a very good and reliable compromisse...
Regards
P.S. Again sorry for my apoorling english :(

The MAF also has a strong bearing on Auto Transmission Control.
Thats why you're "the man", Mike.Quote:

Good to see other's like/use my Air box mod's :D
Thats not a bad question. Would have been better before I bought a new MAF earlier this year.:cool:Quote:

Performance without a MAF is often listless in lower RPM and can cause flat spots on acceleration at wider throttle settings...
MAF also provides better control of the A/F
I had this mod about 3 or 4yrs ago, this mod altered the low down torque of my TD5 so much I had to have it taken out and the standard airbox re-fitted, at the time I had a B Davis full noise chip but no larger intercooler or EGR by-pass or silicon hoses.Quote:

From my experience, have too much air can make an engine preform worse rather than better, so how do you find a balance:confused:
For the record, my Disco TD5 Manual now has a larger intercooler, silicon hoses, EGR by-pass, medium chip/re-map, 3" exhaust, TD5Alive boost box running 18 psi boost, this is better than the BD chip but not by much, although I haven't run the car set up like this with the BD chip & MSB ECU, only with the NNN ECU and re-map.
I really need a bit more torque and power, it still struggles a bit on hills with the camper on.
