Can 1JZ injectors be changed without removing the intake manifold?

requiem what injector settings did you use for the jdm 2jzgte injectors? ...apparently if the settings are spot on your tune doesnt change with the power fc... was that the case for you?

thanks for pics.

No idea sorry i lost my tune ages ago and have really worked on the car since. A good place to start would the the injector info on the Datalogit file server. That might point you in the right direction.

I think from memory you divide the old injector cc by the new cc and that will give you a percentage. Only works if the injector percentages haven't been changed to move the overall maps.

Dont think this would be sufficient?

This won't drain the rail.
(This technique only works with cold start injectors).

when you pull the efi fuse that kills the pump, but are the injectors still active?

Given that the Electronic Fuel Injection runs the injectors, what do you think pulling the EFI fuse does to the injectors?
