my friend got a integra running drag turbo kit, 7 psi with fmu. which i'm not a big fan of fmu.
the integra is running a chip ecu, he have ordered some injector, but be about a week before it come in. and we all going to drag strip this coming friday. so i was going to rechip his ecu and run crome boost option on it so at least the timing will help a little bit. but i don't really know how to do about the fuel.
its stock injector, but fmu increase fuel pressure. so what do i need to do on the fuel setup? same injector cc with increase fuel pressure? or leave the stock pressure alone and just do .75 retard timing only?

 

if you INSIST on going to the strip before the car is ready, leave the FMU until he gets the new injectors, it's likely that it's the only thing keeping the car from running lean under boost.
You can tune Crome to compensate for the FMU's rising rate pressure, but it's not as easy as larger injectors.
What you'd need to do is keep the same values in the fuel map, add boost to the bin and raise the boost slowly, tuning each boost step in the maps individually. You have to do it this way since things are no longer linear with the injectors. Don't be shocked if parts of the maps look strange, the FMU makes things look odd compared to normal FM/injector setup.
Timing, .75* or 1* per psi is a decent starting point. I'd suggest going with the 1* just to be safe.

his best option is to wait for the injectors and do it right... rushing things can damage the engine in ways that are a lot less fun than one trip to the strip.

 

i tried to tell him that, but its like try to tell a kid in a candy store with bad teeth, don't eat any candy. lol. but this will give me something to work with. if it blow up at least i did my job.
