Just curious as to whether anyone has used one of these & what gains were achieved. I have a friend used one on his Clio. Wondered if there were any issues with them. Not the route I'm taking, but just curious.
 
My mate has it .
Tbh i didnt notice any power gains but what yes achieved is more linear power band abit more air/power in the low revs but its all about mapping .
 
Aren't these just a generic map? I'd steer clear to be honest if they are.

From a proper rolling road map you could probably expect 5-8bhp if you're lucky, but from what I can gather it makes the car a lot more drivable.
 
There isn't much information about these and I assume for a reason - if they were worthwhile then there would likely be a lot more of them about.

A custom remap is a lot more expensive, but much better all round and worth the money, if that's the route someone wanted to go down :smile:

How much are we talking for a bluefin @Johnny 99 ? I paid £800 for a scorpion resonated cat back exhaust supplied and fitted and a re-map on the rolling road at engine dynamics. If the exhaust was £500 supplied and fitted that only leaves £300 for the re-map. Bet that's cheaper than the bluefin?
Be interesting to find out...

Just done a quick google and this page came up. Not too far off £300 as it turns out... Seems a lot for a generic map to me?? And quite big power gains if they're to be believed...
 
Surprised at how cheap that is to be fair @Jimmy wonder why you don't hear of them like Johnny said at top of thread?

+12bhp sounds optimistic

Well as I said in my earlier post, I'm assuming they aren't popular because they're not really that great for our cars? We all know that getting more power out of these engines is like convincing Kev that Spa ain't all that great...very hard work!! So when you see a company claiming 12bhp increases, the eyebrows get raised!

I know they were really popular for the mk5 Fiesta Zetec S back in the day, a few people had it done from what I can remember.
 
Yes as you guys have been saying 12bhp seems a lot for a generic map. I'm off to RS Tuning on Friday for a proper map. I'd like to see my mate's blue finned car on the same rollers for comparison.

In pure numbers alone - i gained approx 15bhp (184 - 199bhp) at Engine Dynamics from manifold, exhaust, panel filter, modified airbox inlet and custom remap. That doesnt account for the fact im sure the car was actually worse than standard when i arrived due to not running at its best with standard map and yet "performance" bolt-ons. So a custom remap alone could be in the 8-10 bhp range perhaps in my example.

So a 12hp gain in regard of basic breathing mods and remapping isn't 'easy' to achieve. Let alone 12 bhp purely from a generic map !

Even though K-Tec seem to achieve 215bhp with the same basic mods :smile: The same basic mods they sell and then prove on their own Dyno.

****Where's the 'extremely cynical / sarcastic' smilie ???

I have a Blue Fin map in my R27. It was done by the previous owner to eliminate the kangarooing/flat spot not for power gains as the car is standard (apart from ITG filter). My car runs smooth from cold with no issues. I have read so much cr@p about these online e.g. 12 bhp gains, runs too lean, runs too rich, stay well clear etc. I would agree if you are changing the full exhaust then a custom map would be an advantage but if you want a smooth power delivery the Blue Fin is perfect.

That's the same set up my mate has on his 200. He felt there was an improvement in the mid range & also as you say smoother running. He's never commented on whether the car felt as if it had a 12bhp gain other than to say that's what is claimed. Seems a good thing to so if all you want is smoother running & also as you say the car is easily returned to standard, which was good when he did it as the car was still under warranty. With my exhaust changes I think a remap is the way to go, as you say.
