Is there an easy way to tell if the ecu has been upgraded or not? I purchased my 03 cooper s about a month ago and am curious. It has an alta 15% pulley, cold air intake, and Borla cat back exhaust. It looks like the plug wires have been upgraded also. I haven't looked hard enough to see if the installed an aftermarket header or not yet. I don't know what to look for on the ecu, so if anyone could help I would greatly appreciate it.
With the mods you have a remap would not be needed so its most likely to be standard.
Some have had remaps done but you dont gain much so not really worth the cost. The only time you really do need a remap is when you start changing the cam, injectors etc
Not sure how you come to that conclusion, my advice is to read the Superchips website which says that a remap without a pulley change (and other things like plugs) will give little, but with a pulley etc you can hit 200bhp?
With a pulley etc you can easily hit over 200bhp without a remap. Mine is 217bhp without a remap & as caveman says on the supercharged S the gains with a remap are very little
I have 17% pulley
Orranje air box
Fletcher cat back exhaust
Lightened crankshaft pulley
Dyno'd at Lohen 217bhp
I have now fitted a teflon supercharger after the dyno which has given me an extra 4psi boost so its probably over 220bhp now
My AFRs were still ok at the 217bhp so a remap is not needed
Thats how I came to my conclusion
They are trying to sell their chip so they will big it up as much as they can. If your not convinced that me & caveman know what we are talking about try contacting lohen or 1320 which are mini tuning specialists & ask them what they think of the bluefin on a cooper s & what gains you should expect & if they think it is safe to use or take the risk & buy one to try it out.
We are only trying to help through experience & save you money
I was just thinking about it & I suppose you are right to query what we are saying as on a lot of forums you get people answering questions who haven't really got a clue its just something they have read or a mate told them. I would suggest doing some proper research like contacting the company's I mentioned if you're thinking of buying a bluefin chip (it works well on the mini one but thats about it) check out the other mini forums to see what they have to say.
Hope your dyno shows some good results let us know how it goes. If you have a smaller pulley, decent air filter & exhaust you should be looking around the 200 mark.
Anyway I go on mi hols in the morning so see you in 2 wks
