Title: Apexi power FC and commander - HELP!
Post by: heland on June 21, 2004, 01:53:41 AM
Dear All,

Sorry to be a pain, but as you can see - I\'m a newbieeee, so plese be patient.

My RX-7 was delivered with a Apexi power FC and commander (amongst many other non-standard things that I have\'nt a clue what they are).

The boost setting is set @ 0.9 Bar. Is this the right boost level for the stock turbos?

Regards, Andy

Sounds about right to me.  What\'s the Inj Duty reading like ?

The stock settings for the ecu are:

Setting one: 1st stage 0.8 bar, 2nd stage 0.7 bar
Setting two: 1st stage 0.9 bar, 2nd stage 0.8 bar

A reset ecu uses setting 1.

The actual measure is in kpa, but it\'s virtually identical to bar.

Regards

Max

Gary,

I only got a maximum Injection Duty rate of 85%.

That\'s foot to floor @ 7k rpm.

Does that sound about right?

That sounds about right, 85%-90% is good, anything above that will need to start thinking about upgrading injectors/fuel system.
