I have brought one of the evo chips for my 16vt. Reccommendation is to get a 3 bar FPR but all the aftermarket ones seem to have different rising rates. Anywhere from 1:1 up to 1.8:1.

I assume I want a 1:1 as the chip is already mapped for more fuel and I was told that the 1.8:1 etc are to provide more fuel to people just running extra boost without a chip. Is this right?

Can someone confirm the rate I need.

Also what size lines does the coupe have? 8mm?

From the Website

*boost referenced
*1:1 ratio of fuel pressure increase per pound of boost increase. This means you will NOT need to retune your computer,
get your chip re-written etc as you would with a fuel pressure reg that increases at a rate of more than 1:1.

Just get a fuel pressure reg from a coupe 16v, coupe 20vt or a fiat tipo 3dr sedicivalvole

Cheers Begbie - but they are not available here other that FIAT dealerships at some stupid price. Would be cheaper (alot) to get an aftermarket performance one.

Will go down the factory route though if it's best.

Speak to barbz or find a scrapped coupe motor if possible. Second hand on wont cost much at all

Yes, Begbie is right...
I bought mine for 20 euros

If anyone on the forum has one they want to sell or can reccommend on on-line wrecker please PM me, Would likely have to pay paypal, Cheers

do not get an non-linear rising rate reg, this will send the fueling mad and put too much load on the fuel pump. If the tipo have 3bar reg then so should the 16v na coupe if that helps.

I have 2 pieces from 20VT as I bought one to much.
I live in DK so shipping would cost something also.
