I have a 20B that needs a good Speedinio for it as well. FI/IGN/turbo control would be ideal but I’m no programmer, so a somewhat pre-programmed unit would be ideal, but it doesn’t appear to me Speeduino comes close to that-seems to be ‘roll your own’, more or less?
Tracy did make a 20B fi/ign controller, anybody have one that has ever used it?

Steve. I have 4 port Renesis. My first injectors were on the small side. Size matters. So now I got 4 x 650cc deka's. Flow peaks at 70lpm.

Getting a bit interested in Speeduino. Got a 20b that needs a ecu. Still no airframe though.

Thanks Steve
So a couple of the renesis yellow injectors to replace the red primaries might give us the headroom on those primaries.

Just wondering if others using the 4 port injectors have had the same issue. Tracy, specifically mentions this configuration, so someone must have been using it.
My troubled mind only gets more troubled when I think that our fuel rail is at 50 psi, which I thought might be higher than others maybe using and flowing more fuel.
