Default fmu question

now i almost got my full kit ready for my h22 prelude.
i have
t3/t04e
3"downpipe with closed loop wastegate dump
greddy type s bov
ss oil lines and fittings
FMIC
top mount mani

and i still need wastegate/intercooler piping, injectors, fuel pump, hondata etc.


now my question is my tuner is 3 hours away in a different city.

if i install my kit and just install a fmu with stock injectors/fuel pump will it be safe enough to make a highway journey 3 hours out of town or should i tow it?
(---- load of money)

i wouldn't be doing any full throttle pulls or anything haha. just conservative to the tuner. basically babying it.
towing would be around $500-$600, driving equals 40 bucks for gas and my buddy would buy the fmu from me afterwards.

Um, it seems all you have is an FMU?

Run stock injectors/stock ECU, disconnect the upper charge pipe and throw a filter right on the TB and run with your wastegate open. Reconnect the pipe, swap ECU's and install your larger injectors when you get to the tuners

When you drive it to the tuner you should be fine...I would just make sure that there is NO way to develop boost...I.E. loosen one of your bolts on your blow off valve to make sure you can't build any pressure.

BTW...you put Hondata on your list of things you are going to get. If you are going to use Hondata, Uberdata, Chrome, or any other "stand alone" system you do not need an FMU at all.

Well I never said rev the **** out of it Drive like a normal human being, shift at 3 grand and just watch yourself... I'd really recommend taking off that top pipe though

skip the fmu and just drive it with the factory fuel system.

a t3/t04e is gonna take some rev's to spin boost i would imagine that you're not gonna start spinning it until you're into 4000's, so just take it easy.

besides, worst case is you're gonna spin up more than a pound and the ecu will plop you into limp mode and fall on its face.

^^^^ What he said. Just don't be stupid about it. I can drive around on a small *** turbo and not boost. If you need a little more power without boosting, just rev it higher, BUT DON"T BOOST.

at 120km/h on the highway im at 4g rpm haha. turbo is supposed to spool at 3500ish. bad gear ratios to be trying that. i might just take off the top pipe, run open wastegate and try to keep the revs down. or tow it. i need a few more quotes

It doesn't matter what rpms you are at. If you're cruising on the freeway the won't be any boost. Don't disconnect anything. JUST DON"T BOOST.

Also keeping the revs down is were you would be getting into trouble anyway, since the total gear ratio will be longer and you will need to put more of a load on the motor to get the car moving, thereby, getting into boost.
