It takes some time to play with the software to "get it" and then after that it should not take more than a few hours on the dyno to get it running well.

You ma come back for a second session to fine-tune some things and you may have to play with it a bit next winter to get the cold-start dialed in.

There are many dyno-operators who will gladly work with you, once they know what buttons adds fuel in milliseconds and what reduces fueling - and conversely - how to advance timing or decrease it! Period. After that it is all basics of tuning, no matter what the system. I am available by phone here in the US and so are the guys in SA (on the same time-zone as your Euros!)
As much as I don't read all of these threads, and barely get on them out of interest....

This bears repeating.

I've looked at various systems, all with their schemes on cacluating fuel. If someone is really familiar with EFI, they should be able to do any system, any time. If all they know is their system, and don't want to learn anything else- that's not good- as problems may not be solved in the right way, but in the convienent way. I know I prefer systems that don't use time for the injection map, but I can deal with them...

In the end, it is just fuel, air, and spark.

(on the funny side, our systems now are running in the 2.5 MB range... holy cow- so many sources of fuel, air, and spark do deal with.)

The reversion problem I am talking about occurs when the supercharger shuts off and the throttle is NOT closed.
I see. I wasn't aware that the m62's drive wheel was on a clutch. Perhaps then, the smart way for giuliettaevo to go is aftermarket MAP and get rid of the AFM/MAF altogether - which is probably best for blown applications anyway (SDS/GoTech/Megasquirt).

I agree with these notions, but I think in terms of professional tuners sticking with what they know is what one would want. I mean if you come to them with a new system, that learning curve is going to be on your dime. As a professional, that's not how you want to do business. Especially if some chap brings you a used MAF, CPU and harness and then has to chuck-up for three hours labor - just to find out some component is faulty. I don't know any professional that would want to touch those scenarios. Tuner buds are another story.
