OSE 12P Flex output
Re: OSE 12P Flex output
Hi everyone was just reading this post and was wondering if what you's are trying to achieve would work with a VGT type turbo to control the variable vane of the turbo ? So if you are not familiar with a vgt or vnt style turbo it basicaly changes the pitch of the incoming exhaust air to spool up quickly and then change geometry to flow more air ,pretty much the best of both worlds, I just need something to control the vane .

Re: OSE 12P Flex output
what sort of input does it need? is it a digital on/off or PWM? If so, then the answer is yes. Technically PWM is slightly more complex than that, if it is PWM it may or may not need an interface circuit, but either way it would be doable.

The Variable vane turbos are usually fitted with a propriatry controller. Garrett do their own and I would assume that the other manufacturers do also. They are an expensive bit of gear and the whole turbo is replaced should there be a problem with the actuator!
With the std actuator removed, it is just a lever from the vane posititioner that needs to be controlled. An R/C servo would be able to do the job. It would need to be remote mounted away from the heat and connected via a pushrod. I would however reccomend that a digital servo be used due to it's better holding power.
After a bit of scratching around, I found that 12v servos are now available from Hitec and a couple of other minor manufacturers. This would make powering the servo easy. They don't tend to like running off a power supply or step down transformer due to the variable current draw.
As mentioned earlier in the thread, it seems that you would need to invert the signal from the pwm output, or use a servo driver to control the servo. Not too sure if the frequency is the same though?
Servo drivers are pretty cheap units and maybe this would be an easier option? Could even couple the servo driver up to the throtle linkage or TPS to get some basic control happening?
