You don't have the "typical" setup. 95% of the people asking about this upgrade have a relatively stock engine with minor mods and a chip. For them the FPR is a waste.

true but I am also thinking in long terms for him, as he mentioned he might be later on adding more upgrades to his vehicle.

hehe, non volvo specific? NO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I fail to believe it.

So that is not rising rate right? Just yer normal everyday adjustable FPR.

FYI a lot of aftermarket FPRs are rising rate (AEM, some OE Bosch, etc). Pretty common stuff.

Thanks Aaron,

Today I've received the FPR, it has a vacuum line ;-)

It looks very hot!

And yes upgrades will come.... :D

what are you using to tune the car??

I don't know yet, stock Motronix 4.2 ECU chipped by Rica or standalone.

I do want to tune the car myself, so standalone is the only solution. But I love my Airco, Cruise control and ODB 1...

If you are going standalone, or custom tuned Rica, etc there is no need for an adjustable FPR...

If you are going 650 CC injectors some adjustability is nice I think..

And this adjustability cannot be programmed into the ECU? Unless the Motronic ECU cannot properly idle and fully control the pulse width of injectors that large, which I doubt it cannot, then it is not needed.

In other words, what is the point of having a perfectly tuned ECU if you are just going to throw it out the window and override the ECU with an external fuel adjustment? Your perfectly tuned ECU isn't perfectly tuned anymore. If it's because you have made changes that require more or less fuel, then get your ECU retuned. This is why you got a programmable ECU in the first place is it not? If the ECU cannot make the appropriate changes then this is another story.

You are not going to find many professional race cars using true standalone engine management systems coupled with an adjustable FPR or other piggyback fuel hack products, unless used for temporary tuning purposes only. FPRs are called "band aids", as are piggyback controllers like MAF controllers, VAFC, etc. Band aids are generally used when the proper solutions are unavailable, like programmable ECUs. Since this guy is going Rica or standalone fully programmable mgt, he has no need for band aid fixes anymore.

Unless he wants the "wow" factor of having shiny red bits under his hood. Me, I'll take the programmable ECU.
