E85 Blending with CA91-why not?

[RALLInspired]

^I was going to bash you for necro-bumping this thread... BUT that's good info... Too bad just the ecu by itself is $2200... Add another $100-$200 for a harness and ANOTHER couple hundred for the flex-fuel sensor and it all adds up to the vast majority of us just dealing with flipping a switch!

Or simply installing a wideband and gauge to monitor AFRs.

The features that the PRO EFI unit offers as a whole are pretty awesome. Failsafes for just about anything you can dream of.........true launch and traction control......fueling from the true Volumetric Efficiency of the engine.......true frequency based filtered and windowed Knock control......In regards to Ethanol, it will self adjust timing, boost pressure, and several fueling conditions to properly accommodate the varying Ethanol content. Pretty cool if you really need the flexibility and can afford it. For 95% of us the good ol stock ecu and map switching will be just fine :mitsu:
