Honda Fit Info

We've now supplied about 20 systems for Honda Fit aircraft conversions. Below are a the answers to a few common questions on these systems:

You must change the drive by wire throttle body to a cable activated one.

We can run any of the port injected engines, cannot run the later Direct Injection engines.

All programming is done through the panel mount or hand held programmer supplied with the system.

We don't use any of the stock sensors. We supply a new MAP sensor, temp sensors and crank sensor. You'd have to re-tap for the water temp sensor and fab a bracket to hold the crank sensor.

You can use the stock coils and injectors. You must graft on the stock coil and injector connectors to the new harnesses we supply.


We also supply Titan Aircraft with systems for the Honda V6 powered T51 replica fighters.
