Default tuning with an FMU

I have a Cartech adjustable FMU...i am just wondering what is involved in tunning with one of these. also will i need any timing changes for a 5-6 PSI setup?

Honestly there isn't really any tuneability for an FMU. If it's rich, it's rich, not much you can do about it. And try your timing at stock, if you notice any detonation retard timing a little. At that psi, you probably won't have any problems staying at stock timing, and with the FMU you'll be running plenty rich.

i have the same FMU and it is shitty, everytime i hit about 2psi i go so damn rich i bog down. i am saving for the "hack" so i can actually enjoy the boost.
good luck

I'm considering a Vortech 10:1 FMU.. with stock injectors and stock fuel pump at 7 psi, will I be running too rich as well? Is there anything I can do about that (short of going for engine management..)

I'm starting to consider a Apex'i SAFC now. Particularly one of those Gen 3 ones, just because they seem to be cheaper than an FMU, but more effective..

This is interseting. What happens when to fuel flow volume you riase fuel pressure?? it drops like a rock. typically itll drop 10% every 2 psi and by the time you get to 70PSI you have little to no flow left with a stock pump. your gonna need a pump. also id highly suggest getting rid of the fMU and converting to OBD0 honda something or OBD! and getting one of the freeware editors or hondata zdyne etc get the car tunned right pleeeeaassseeee. im tired of reading storys about blown motors. also at 6psi your arent really getting much of a gian anyways. might be worth it to take the turbo off till you can afford engie management to go with it, your engine will thank you.

I think im gonna stick with the FMU for now. But if i decide to go the AFC hack route in the future. what will i need. From my understanding i would need obviously the AFC, 450 injectors. (how hard are these to modify to fit to a honda?) and a resistor box?

Iv done a lot of research on this board and could not find much about the resistor box. What is it? where can i get one? and about how much do they cost?

thanks for all your help. sean88accord..i think you need to step down and realize not everyone is a turbo guru. Instead of putting people down, why dont you share your knowledge in a civilized manor?
