[/img]I have a small jetboat with a VQ30det installed
all was well until I tried for "A bit more boost" to achieve this I installed 580cc injectors (Flow tested at 620cc) and "Spit fire coils"
the turbo is already an after market garret "Nock off"
The project sat still for a long time as I have started Jetsprint racing and have a V8chev
long story short we had a sudden rush of shit to the brains and decided to get the old river boat running
Our tuning was going OK till my laptop ran out of power then a Saturday call to Matt got us running on my tuners laptop "Thanks Matt"
our tune was ok till we tried to "Burn" then all hell let loose
Rich Rich Rich
we tried all sorts of different angles to get around the problem
several sets of plugs later we are no further ahead
I suspect a faulty TPS?, as the Rich happens after a big throttle movement
maybe the TPS still shows 5v at idle?
I will check this next during the week ahead
Any ideas?
By the way
My tuner is used to LINK and wonders if negative values made available on the fuel map cells might be a good idea?
