sorting out wiring on my install while awaiting delivery,just got a couple of queries,before i unpick factory loom

1.How to wire boost control without using second WB02 driver??

2.injector fly back resistor, my Low Z injectors with current 10ohm / 10 watt resistors (one per inj)give total Z of 13.8ohms per injector,do I need to use flyback,I read all info & think yes but ??

Install on Lexus 1UZ-FE v8 twin eaton M62 s/c's in volvo V90
Anybody thinking of using 1UZ-FE instead of RV8,can help with info & where to buy parts etc.Exhaust Flanges,bellhousings,engine mounts
Currently running with OEM ECU,piggyback & fmu,circa 430 hp @ 8psi
thanks volvotech

rob@vems.co.uk:
Boost control solenoid can be driven by the spare stepper motor drivers on: EC18pin4, 5, 10 or 11.

Injector flyback is required for all installations, it gives the injectors a path to discharge through.  We've had excellent results using resistors and the transient suppression diode thats supplied in the spare component pack.


I have half a mind to try a 1UZ engine in my Nissan to see how it will go.

thanks Rob
only thing is intended to use Std idle valve (4 wire drive & ve-),if swap to Bosch 3 wire idle can i drive from a pr of terms from EC18: 4,5,10 &11...8 cyl seq inj so can't wire as per your install page EC36:6 & 17 in use for injectors

rob@vems.co.uk:
A 5 wire IACV!  Got any info on that?
Theres a number of possible IACV options if you're moving from stock.

Those diagrams are suggestions of connection BTW, the key with VEMS is its versatility, plenty of possabilities, just need to decide on which ones to go for.

700mm3, I'm going out to measure my engine bay...
