So what setting is my car actually on then?? Anyone know???

Switch MAF Throttle Power
Position Boost Response

1 LOW LOW HIGH
2 LOW MED HIGH
3 LOW HIGH HIGH
4 MED LOW HIGH
5 MED MED HIGH
6 MED HIGH HIGH
7 HIGH LOW HIGH
8 HIGH MED HIGH
9 HIGH HIGH HIGH
10 LOW HIGH VHIGH

POSN 1, 2 & 3 Borsch Maf has some deterioration OR MAFAM SWITCHED OFF

POSN 4, 5 & 6 Borsch Maf has moderate deterioration OR PIERBURGH MAF FITTED

POSN 7, 8 & 9 Borsch Maf is very poor OR PIERBURGH MAF FITTED

IF YOUR BORSCH MAF IS OK, then switch the mafam off and use settings 1,2,3 or 10

If your Bosch MAF is out of spec, the MAFAM section will amplify the error.
So if you don't want your ECM thinking that an at idle airflow figure approximately that it would expect at around 1500RPM, then don't switch on the MAFAM section.
What a genuine Bosch MAF will cost you, will soon be recouped in extra fuel savings

Wrong again.

If the maf signal is weak it will not amplify a weak signal and make it weaker. It will do what an amplifier does - amplify it - ie make it bigger which is exactly what you want.

Ron I'm afraid I will have to contradict you on this occasion.
The Bosch MAF will rarely if EVER fail with a lower than expected airflow figure, they fail 99% of the time by the signal given to the ECM being higher than an in spec MAF.
The result of amplifying a signal which is higher than normal to begin with, is to compound the error.
People will see an "improvement" as the ECM sees a airflow figure at idle which is more akin to that seen from a normal in spec MAF at 1500 RPM, i.e over fuelling considerably

I have a brand new Pierburg maf. At present my synergy is set on 5 with maf switched of. The car performs realy well, should I have the maf switched on as well, and will this enhance the performance.

Yes, you will need the MAFAM section turned on in order that the Pierburg MAF give realistic and meaningful figures for the DDE4 to work with .

Hi Brian thanks for the info, I thought the old bus was going realy well. Am I correct in thinking that setting 5 with maf on will be ok.

What planet are you on!

I have sold thousands of mafam, digimafams, and Synergy 2a for the L series and BMW engined cars and all do exactly what they are designed to do. (I have the feedback to prove it, not that I need it as my satisfied customers can speak for them selves)

if none of these Bosch mafs had developed a weak signal then:-

a) The products would not have worked or just produced smoke from the overfuelling.
b) Its complete nonsense (and ignorance of both the digimafam and Synergy 2a's functioning) to say that "improvement is due to an increase in the airflow signal at idle" WHY? because the signal is not boosted equally over the range - there is little or no boost at idle.

Yes, some mafs to go high and I clearly state this on my website and in this case you do not want to amplify it - obviously. In which case you replace the bosch maf with a pierburgh where a Synergy 2a or Digimafam is fitted.

But what do I know - I've only been selling mafams since 2004, having proved it worked for me on my 45.

You may a T4, but you have a lot to learn and are clearly not conversant with my products. I don't think you are doing your reputation any favours.

Which maf do you have fitted?

If its the 070 maf, then you should be on settings 6 to 10 and with the maf switch on.

Hi Ron, I am afraid I dont know what sort of Pierberg I have got, it was fitted by Jules 6 months ago, and he set the synergy 2 at the same time. Whatever setting it should be, the fact is my car has been achieving 48mpg and drives very smoothly.
