fuel cut and piggyback questions

[flyspyder55]

putting a 1jz into my ma70 and i'm fairly unfamiliar with the stock ecu, so i have a couple questions.

1. i hear many hit fuel cut as low as 14 psi on the stock twins on cold days... whats the best way to rid the car of fuel cut, just a greddy FCD?

2. ive got some precision 800cc top feed injectors that i'd like to use, making my own topfeed rail is no big deal, I've got a SAFC 2 sitting here but i know thats WAY beyond the capacity of the SAFC2's tuning limit. is that a piggyback i can run that might run these injectors to any decent degree

Put a greddy emanage blue on the car, u can control up to 950's i believe with the emb on a 1jzgte ecu and the emb has the ability to remove boost cut.

IMO do not run over 550cc injectors on the stock ecu.

For fuel cut, yes a FCD/BCC will eliminate it. If you all ready have a AFC, just put the afc on there though. Once tuned you'll gain a little headroom for fuel cut. Then once you hit fuel cut you're out of fuel, so need to upgrade your fuel system.
