Hi,
I went ahead and converted a car to E85 today.
Here it is, please excuse the dirty engine:
That's it, bye.
Just kidding. If more cars only came from the factory with the freedom to put whatever the [censored] I want into the tank built in...
So let's get going, shall we? Usually the conversion a pretty straight forward job, because the newer piggyback boxes come with a harness that just clips between the injector and the connector. I wanted to build a harness like that, but the injectors on this car have the notch on the plug offset, and standard Bosch EV1 plugs don't fit. [censored] Hitachi MPI.
Instead I cut the negative lines from the injectors downstream and added the EV1 plugs there:
It would've been better to use a 5-pin AMP SuperSeal connector like some cars do stock for all injectors and +12V. If you have them.
The box has automatic cold starting, so there's a temperature sensor which I put on a coolant hose:
Other than that, it's just +12V, ground on the chassis and a connection from the lambda probe for automatic fuel adaptation. And here's the ECU in all it's glory, hidden inside the relay compartment:
Yes, the crimp connector on the ground strap will be added later.
I've had this box in three different cars over the last five years or so. After about 70k miles traveled with it, the numbers of problems related to E85 are zero.
What does it do?
By the way, the manufacturer of this car says "This model is excluded from E10 compatibility even after 2001". I did 45k miles on one just like this (which I still have in storage. yes, it's cleaner than this one) with E85 without a single problem, with the engine and fuel system still being in perfect condition. Whazzup with that?

What does it do?
- 10-15% more miles to the dollar in my area
- Noticeable more bottom end torque.
- Less CO2 emissions (I had one tested, it's an order of magnitude less)
- Acts as an injection system cleaner and keeps the everything sparkling
- The engine runs on [censored] flowers, goddammit. How cool is that?
