Hi,

Just bought Apexi PFC, complete with Japanese user manual :-)

How do I go about changing the base map for my 740cc nismo/tomei injectors? (supplied by Andy F Red top ones)

Is it something like old size divided by new size then change the amount with commander?

I have just plugged it in straight from the box (New) what is the injector size in the base map?

How do I find lag times for the 740's?

Thanks

George

 

Original Injector size / New injector size * % trim

Ie - If you are changing from 440's (at 95% trim) to 740's then...

440/740*95 = 56.5%

This will only be approximate, but will be good enough to get you running so that you can fine tune afr's

I've left the lag at zero, and it seems to be OK - don't know what others have done?

Thanks,

Just done the calcs and set injectors to 59.5% leaving the trim at 100 at the moment.

Is anyone running with PFC on the same 740's as me? What have you set lag times at?
