Its gonna be decades before the crappy pumps are taken out of inventory, now that the word is out and their old customers have retrofitted to other pumps.
No telling how long those pumps will languish on retailers shelves.
Booyah, thanks for the link. I'll probably build my own PWM from discrete parts. There is a particular pressure transducer I want to use, and I want to build in some circuitry to shut the pump off if the engine isn't running. I am concerned that pump motor is not rated for continuous use, but get the strong idea that running the motor at reduced voltage will be OK. And I want to use it to experiment with dynamic timing adjustment, noting that fuel pressure affects timing. I'm well known to monkey around with things like this.
One thing I am trying to find out is a good way to monitor MPG in real time. I have speed info from the VSS sensor, but, given both fuel supply and hot fuel return, accurately measuring instantaneous fuel flow is more of a challenge.
