Hi peeps I need the part number for the 4bar fpr used on the 20vt coupe, iv just bought a fc chip from R1DAN and it's running sweet but he had a 4bar fpr as I have a 3.8 fpr and I don't want to risk under fueling the engine in hi boost

please help and there's also a chance I may be able to get a few of these up for grabs like the 3.8bar ones iv sold already

cheers

I would be very concerned about running that chip, it's by no means a plug and play option.

The only difference between mine and dans is the turbos, our engines are very similar the only difference is that dans rear section exhaurst is custom made but the dp and middle is blueflame like mine, we both have done the fuel pump mod, both have standard injectors, I will soon have his clutch, blitz boost controller and engine mounts.

My engine is from a late plus and was low milage and stock when I bought the car, I know every engine might slighty be different but I'm confident mine is strong enough

my last power run on a gtec2 made 290bhp@1.2bar of boost
no fueling problem at all, so I'm confident another power run after all is fitted will produce a higher gain

but if there is issues flea it will be coming up to you for a full map if that's the case, I just didn't see the point of binning the ecu with the car

If I told you that not a single car out there is driving with the same FC map, perhaps that might suggest why I don't think it is a good idea. This process becomes ever more extreme as the power and modifications increase, indeed to say that some cars differ is an understatement in magnitude. I could pull out cars with identical specs with very different maps. Swapping from one to the other would do no harm to one car, but the other would suffer relatively quickly if driven hard.

Suffice to say, if I did map your car, it is a 100% certainty that you wouldn't have the map from Dan's car. Running at the dyno to check the fueling would not appease my mind at all even if it was "spot on", but then again I know what it takes to map these cars to the safe limit.

True.... But getting back to this post can anyone tell me if a 4bar fpr Bosch 0280160575 is the right one?

Well sod it! It has 4.0 bar stamped on it, these are used on 20v 1.8t vw's as a upgrade and it fits so hopfully it works.

well its now a balistic! taken it for a blast and its fansastic!

TAG pal, I think Leighton was simply pointing out that having a strong engine is by no means a way to say it's impervious to poor mapping, a piston will still suffer det damage / melting regardless of condition, Aluminiums melting temp doesn't change

Personally, I'd get it mapped properly, you could be cracking your ring lands as you speak, very common for over fuelled coops

IMHO, been there done it, spent a fortune
