Have seen other motor driven PS units, but never seen one with a stand alone electronic module.
I had no reason to change the rack on my Cressida, but wanted to dump the stock belt driven pump, but because of a 2:1 steering quickener, still required power steering. So the Toyota MR-S electric pump fit the bill.
It has all minimum required electronics built into it, like automatic digressing power assist, that the faster the vehicle speed, the less assist it gives, on a linear rate.
And someone has come up with a $65 plug-in module that gives you the ability to program the assist rate.
All it needs is hoses to my rack, switched electrical power, and a speed sensor input.
Most of those 10/22 full auto conversions turn out to be hack jobs on the safety lever allowing it to be rotated counter to the normal motion and this is a disaster in the waiting. File too much, fail. File too little, fail. How many safety levers does it take to make an illegal conversion?
Not talking about illegal hack jobs....
Talking about conversions by licensed class-3 manufactures, and legal purchase with a class-3 tax stamp.
Quality conversions have a lot of machine work, and a lot of new & additional parts.
