I read this months article on the Motec engine mangement system with
interest. but is it really an improvement to ditch the whole intake system when as i understand it only the afm is causing the restriction. replacing the BMW desingned cold air intake system with a big chunk of foam and a shiny bit of blue pipe that will draw its air off the back of the rad doesn't seem like a wise move? ------------- 1992 clio 1.8 16V Good 1998 Subaru Impreza Turbo Terzo Great 1987 M3 Diamond Black Awesome (Now awesomer with Billys & Eibach) |

yep..its a bit max power looking!
I am sure there must be a way of routing the airflow properly using black Samco hose which would be much more in keeping with the cars pedigree. Trouble is, the mapped cars I have seen have all used the same method with the loud intake hose and big foam filter. Nick ------------- |

you should ask people with the kit installed if they have been happy with the mapping.... ------------- E61 520d, slow and buzzy but my wallet likes the mpg..... |

I have the kit and you are correct, the air filter arrangment is not the best idea so I elected not to have that filter and instead I modified an original airbox like this...
Once I was happy this was the way to go I puchased this... 
And fitted it with a black hose... 
I installed the kit myself but due to some quality issues I had to get Powerstation to map it. All of the high load stuff was OK for fueling (haven't checked the ign adv, but I will!) but when I asked about the cold start, idle control ect I was told to "just mess about with it until is seems right" 
Well I've messed a bit now and it drive OK. If I were doing it again I would buy the ECU and I would modify my own loom (or an ebay spare) to make better use of all of the functions the ECU has. It would probably be cheaper too. Steve ------------- 1990 Sport Evo No.47 Motec EMS |

The other thing is they tell you the cost of the kit, the fitting cost but no
mapping cost. stevesingo that does look a lot tidier. ------------- 1992 clio 1.8 16V Good 1998 Subaru Impreza Turbo Terzo Great 1987 M3 Diamond Black Awesome (Now awesomer with Billys & Eibach) |

I have driven Steve's car and that is one of the best (if not THE best) M3's I have driven so far! 
Considering that he "fiddled" with the mapping on his own, the result is remarkable. 
Some of the so called "experts" should have a look at his work to see how good a proper mapped car can drive and I suggest that some of these "experts" should be banned to go near a car while carrying a laptop. Not even to mention to be allowed to charge for their "work"

Yeah, me and Steve make great fiddlers...
I wasn't happy with my 'expert' tuned Motec, I re did the whole ignition map and fuling myself, it is way better. I do need some dyno time though to sort out the areas that you can't really get too while driving on the road... |
