fuel cut problem with map-ecu and fcd

[ebugatty]

Hello all,
I've a friend who have a fuelcut problem about 3500tr/min when his avc-r is at 1.5bar .
His mod is map-ecu with fcd , 550cc injectors ,SP61GT and avc-r . He is at 0.75 wealth of lambda value.
So can you explain where the problem come from ?
Thanks
(Sorry for my poor english )

I wouldnt think you would need an FCD with the map-ecu if it was tuned correctly. Maybe at the boost level the 550's are borderline maxed.

That's what i think for the map-ecu and FCD ... But for the fuel cut , i've seen a supra at 600hp with 550cc injectors ,so they can be good for 500hp no ?

you shouldnt even need the FCD if your using the map ecu.

And yes 550's are good til a lil over 500HP.
