Fuel Cut Out

[RamR33]

hey guys,

car seems to cut out around 6900rpm which i think is its limit on revs but seems to want to go a lil more.

mods are

040 fuel pump

greddy e-manage

550cc injectors

pu turbo .82

FMI

Z32

new coilpacks

Bcpr7s gap .8

Is there are fuel cut off or something like that is that why cause it just backs off when hitting those rpms.

Any ideas cause this turbo just wants to go more cause of its size.

doesnt give me much revvs to play with as it comes on strong around 5000rpm.

Yes

Wait I just read your post again. You don't have a stock ecu which limits at 6900 on an rb25. The limit on the e-manage is probably set at 6900

[RamR33]

oh ok thanks for that...only reason was asking cause i see alot of rb25 getting secong gear to 100KMS on RB25.

[HR32GTS 4DOOR]

Yeah my rb20 will get to 100 in second even with the short NA diff. Ur spedo may be out if your not getting too 100

[RamR33]

i have 18inch wheels with profile 235/40

would that make my speed off by a bit? i seem to get to around 95km in second gear.

Man I cod get 115 in second ringing the neck out of it but 18s I believe are still the same rolling diameter as stock don't quote me but

[RamR33]

yeah but at what rpm you getting 115,surley not at 6900rpm?

my computer cuts out at 6900 so im guessing you taking it to more then that rpm? unless my speedo is just off...

what revs at when you on 100 or just over that speed?

[mad082]

my 33 gts-t used to get around 110-115km/h at 7500rpm (the stock redline)

i'd say that the emanage in your car is set to redline at 6900rpm instead of 7500rpm.

[RamR33]

is that like a safe thing to set it there or is there a way to adjust it to rev a lil more on the e-manage blue?

is it in the tune that sets it to 6900rpm?

[Bsa]

Maybe it's set to that limiter because it was to difficult to tune past that rpm? So instead of guessing timing and fuel past 6900 he just made that limiter
