I have an rtek 2.1, which is based on the stock map (which accounts for bi-voltage operation). It does have fuel adjustment which I could use to lean it out but....why? I'll let Mazda figure out the fuel economy (this is a daily) and I'll spend my time refining the boost portion. As far as failure, I've found one case of either the resistor or relay failing....I like my odds
But when the time comes for me to sell a kidney and get a Motec, I'll rip out everything stock I don't need and rely on the ecu.

You're thinking about it backwards. The more voltage you give the pump, the less A's it needs at the same pressure. So, you won't burn the thing up running it constantly. My pumpS see running voltage minus about .2V and I've run them for 21 hours pretty much strait. If he burned out a pump while running dual intanks, my first guess would be insuffiecent wiring, both in size and voltage. The smaller wiring will create resistance, the two pumps pulling more A's than it should causing heat. Heat causes more resistance, and it just becomes a downward spiral untli the V goes too low, the A's go to high, and then they burn up

Ahhhhh! I've never liked electronics, at least the planning/understanding part. Guess I'll have to bust out those old physics books....I make some damn sturdy connections though,lol. I don't remember the details of his setup, simply that a pump was burned up.
