Aquamist HFS-1, GM BCS, and Tephra v5: together at last!
 
Like ebony and ivory, I have my Aquamist HFS-1, GM BCS, and tephra v5 working in perfect harmony on my car. Boost is semi-dialed in so that my base map hovers around 21psi and my alt map hovers around 26psi. Base map is a basic pump gas tune I put together for myself, and the alt map is a modified version of my tune from my SMC alky kit. Both need refinement, but you get the idea of how awesome these technologies working together is!

I donated money to Tephra, did you?

There is no fancy footwork here, there are no extra switches. I have a 240k resistor running from a 12v source in the dds junction box that is switched on and off using the dds and then runs to pin 42 of my ecu. Simply turn dds off and you drop down to a standard pump gas tune. If any of the standard failsafe catches on the aquamist kit are hit, it falls back to the pump gas tune (and low boost) as well.

For some reason i thought i read that the tephra v5 was not out yet for the 05 model years?

He is not using a USDM ROM any longer, for this to work he had to switch to the Euro one.

im jealous! So how much was the whole kit? Are prices comparable to doing an e85 conversion?

I really have no idea, I suppose it would be about the same, yes. You could use tephra v5 to make your car semi-flex fuel, have a pump gas map and an E85 map :)
