R&D Power Shot EFI ?
Anybody know how this new unit differ's from the one we are all using now. I notice there are no pots to turn and the R&D description says 10 minutes to tune, wouldnt that be nice.

They have an add or minus for fuel. Probably have to run it at a certain rpm and add fuel or take away, but thats just a guess.

Too bad it only does fuel.... Whats the latest on the software being developed which alters timing also? Thats what im waiting on.. Bump up the timing when racing with race fuel, then back to normal when just cruising on pump gas..

speed.. is that a row of l.e.d's on the unit..could they be a lean/rich meter..if so is there a sensor they could have taken a reading from
would take out a lot of guess work out of the riva unit

The only way to read AFR is with a sensor in the exhaust... Unless they use the reading from the cat temp sensor.
It may work... who knows if better or worse that the Riva controller. $450 something tho...
I will wait for Mac and Advent, unless someone else wants to test it.

WFO... any news on how long the mac or advent will be

A traditional O2/heated O2 will not last (for long) due to the conditions in the exhaust... the heater just put it into closed loop sooner than a traditional galvanic generator.
If one could decifer the readings generated by the cat temp sensor, you may have some fuel control. (in theory)
any news on how long the mac or advent will be
Macs ECU real soon

this system has already been tried and tested on two strokes.they are running an o2 sensor in all of the exhaust ports where the sensors control a sequetial fuel injection system and each cylinders afr can be controlled individually. i dont think ski,s are qiite there just yet.as i said to salty earlier why not use an automotive control unit with infinate adjustment and software changes available.
