Rover 3500 Vitesse injector dead times, 0280150105

Post by spitnl »

I have just tested these using MS2 V3.0 and the original power resistor pack.
Manufacturer: Bosch
Part Number: 0280150105
Injector Dead time @13.2V (ms): 0.537
Battery Voltage Correction (ms/V): 0.178
Flow (cc/min): 180 @ 36psi/2.5bar

I've not checked this, but according to another website they were fitted to:

Flow rate I work to for the RV8 running factory fuel pressure of 36 psi is 173 cc/min. But could well have been wrong all these years. :D

Can't help it.
This is what the test produced.
The 30s 100% duty cycle and interpolating the other test results both gave 180cc/min

If you do a search on the injector number, the flow usually quoted is 191cc/min @43.5psi
Which converts to 173.8@36psi when you do the maths.
Maybe my fuel pressure runs at a slightly higher pressure.

That doesn't change the flow in cc/min, N-Heptane flow in cc/min is the same as for petrol.
You are right that lbs/hr and g/min is different, due to the differences in density.

Yes - I simply used the corrected figure found on the Stan Weiss site. But my fuel pressure was checked with a gauge and is correct.

Well, I tested my fuel pressure regulator, and it is 36psi.
So that's not the problem.

Then I flow tested 3 other injectors.
Results?
174-178-174 cc/min, checked several times.
So it's the injectors that caused the problem.

The dead times of the other injectors where within reading error.

The spec for the resistor pack is 6 ohms +/- 1 ohm. Injectors 2.4 ohms +/- 0.5 ohms at 20C. The total resistance of both and wiring given as 7-10 ohms. I'd guess that could give some variation of true dead time.
