Turbo ECU and Fuel system upgrade

[volvoman37]

recently joined the F+Ti club and pretty much left everything with the fuel system stock. just wondering what it would take, parts wise, to upgrade my system to the turbo 2.4 setup, and what would i gain from doing so?

[linuxman51]

ignition and fuel ecu, injectors, and the resistors

and maybe a maf on those funny 2.4 cars.


what you gain are:
fuel maps better suited to what you're doing with an adaptive ecu that can further trim as needed (maybe, its a start at least)
ignition retard under boost, wether na lh does this is as of yet undetermined
bigger injectors.
you'll be able to safely run more boost.

I just did what you are talking about. You don't need a new AMM since the 2.4 NA cars use the same AMM as a turbo. An ecu from a 90+ 740 and ignition computer will do the trick. Message me if ya have any other questions. My car works awesome! Oh yeah, the only "funny" thing about lh 2.4 is that it kicks 2.2's ass! Hahaha!

oh? go beat my lh2.2 best time then.. 14.8@10psi with the t cam ;)

is there a way to test or find out if NA 2.4 will retard timing?

How do it know when there's boost?
