Does anyone know how to do this? I would pay.
Also can you modify your car on the cosmo ecu with intake exhaust and intercooler and turn up the boost or is it like the stock fd ecu where you have to keep it at 10psi but you can have all the bolt ons?

b mods: the cosmo has 6x 550cc injectors so you can mod it til those are maxxed out

will run any more than a 13b.
13b= 2 rotors
20b= 3 rotors
the fd computer is kind of short the ability to run that
extra rotor,,, unless there is something i don't know about.

The 3-rotor ignition pulsing is done via the standard ignitors as the ECU just gives your normal 2-rotor output.
I'm talking 13B ECU from the JC Cosmo, (90-95) not FD RX-7 (92-02).
By the same token, its more "cost effective" to pay that $500 & have an adapter harness made for the haltech.
