Alpha N or Motec ?

Uwe, forgive my ignorance but with this piggy back unit do you also do away with the AFM? as it looks as though you do from the S14 site ?

By far the best ECU/AFM replacement is..... MoTeC

http://www.powerstation.org.uk/ the place to get it done

Combined with a Milltek exhaust =

and the cost! The piggy back unit is EUR 850 if I remember right. 215DMX, yes the AFM is removed. This is what Alpha-N is about. I would like something to suggest.
Have you done a track day with the M3 so far? If not, go and do so. I few months ago I was close to invest quite a bit of money for a engine management system. Ask me now after doing some track days where I would invest the money. I agree with all the improvements of a MOTEC or any other system. The question to ask is, do you really profit from it???? Better throttle respones as an example. From my point of view not very important on track. Pedal stays down most of the time anyway! Maybe in the future whem my driving skills are as good as the cars abilities, I will benefit from a management upgrade. But for now I will get my suspension and brakes sorted. (and some decent tires)

Where are you getting your coilovers from and how much are you having to pay? I,m asking cause in about a months time I,m looking at ordering some.

Alright Doc, how are things .... Bexleys will certainly be fitting them for me can't wait, unfortunately the lead time from Leda is about 5 weeks at the moment, sigh... summer will almost be over before I get them fitted.

250bhp or not the I'm going to be flying past you soon .....enjoy Croft next week, wish I could be there

Tom......I will spank your ass like I'm your daddy.

I'd agree that a nice set of cams is a much better bang per buck than Motec. A camed up car would make more power than the same car with stock cams & Motec.

It's the power under the curve where the Motec will gain, great for general driving of the car, but whether it would be quicker than a camed car round a track when both are at full chat I'd have my doubts.

I still like that sort of conversion as mine is a daliy driver and it would make the car much more user friendly.

I'd prefer a car with Motec and standard cams to a car with just hot cams, even if it was a track car. Motec gives about 15-20 BHP throughout the rev range, not to mention extra torque, so it will haul you out of tight hair-pins. A cammed up car would give that gain only at the top. I don't think it would get any more than 20 BHP. How much did you gain Martin?

The debate rages on.

Anyway, Tom....b***ox to all this, you'll have alpha-N of some description before long. I'll take bets on it. And you, Martin.

lol... thanks John, no doubt you are correct. I was all out to stick some cash into an alpha-n setup but there is no question that on track it was not power holding me back but suspension....

so for now I have changed priorities, handling first, alpha-n second.

my car made 207bhp standard no cat unmapped,217bhp remapped on the same day as Colins,but because it`s a bit slow a pair of cams and remap are going in in a couple of weeks,will post results.Also latter in the year alpha N if I feel it needs it.sh*t you BOYS are going to have to learn how to drive                   Cheers Jon
