Injector Settings

[SargeRX8]

Hey all,

Well Ive got everything I need to start installing my turbo into my car. Currently I run a Power FC with a tune for standard parts and 10psi. I need to fit on a new turbo and my new nismo 740cc injectors(red top).

I read somewhere that the injectors need to be setup on the handcontroller. Does anyone know the settings for the hand controller? Like the % and the ms lag thing? I'm going to fit all the shit to the car my self and have it driven to Advan performance. Obviously I will be driving at turtle speed I just need to get everything back to a driving state.

If I put the stock ECU in, will it make the correction to the injectors or will it shit it self?

Ive already got to pay money for a tune and probably a new clutch so not too keen to pay the same shop to do installation bits coz thats something I can do my self.

What are the lag times for the Nismo 740cc injectors? These are side feed for an RB25DET.

Old injectors are 370cc new are 740cc so I get a 0.5 value thing which I don't know where to use because on Paul33's guide it says enter that value... Where? Theres only a percentage option and a Msec option for delay.

Cheers guys.

Pauls FAQ has in detail how to work out your injector settings. And I'm pretty sure it has a table with the settings for common injectors, which your nismo's are

change the first column to 50% for all 6 (370/740 = .5 or 50%)

the second column is latency correction. you need to find the latency value for the 740 and subtract it from the standard value (~.64ms) then enter the amount. for example nismo 555s are .81ms from memory. .81-.64 = .17, pfc only goes to the nearest .02 so enter +.18.

As above will get it driveable hopefully. Otherwise just fit the injectors when u drop the car off. Only a 20minute job
