Default Won't start with 750cc injectors

Ok I have a B16A that with a T04E turbo. I have a set of 750cc RCI P/H Injectors that I had installed on the engine. The car won't start with these injectors on there. But when I put the stock ones back on the car starts right up. I still have to install my Hondata S200 to my ECU. After I install the Hondata S200 will I be able to adjust the amount of fuel it gets at start up? Because it dumps way too much fuel for it to start. I just want to be able to get the car to a tuner. I'm a complete n00b when it comes to Hondata. I've never used it before. How can I get the car to run normal with the 750cc injectors? Any input would be greatly appreciated. Thanks in advance.





The engine picture is an old picture. I have an MSD Digital SCI now with a blaster 2 coil and msd cap. And a Blox 68mm throttle body. I don't think I had the fuel rail or FPR installed in this picture either or the wastegate pipe.

you cant just plug in the larger injectors and expect them to work with the stock ecu. you need to have the ecu programed for the large fuel injectors. use the stock ones to drive the car SLOWLY AND CARFULLY WITH NO BOOST!@! to your tuner then install the injectors and have your tuner sort out the fuel issues.

Your also gonna need to wire up a resistor box to use those peak and hold injectors. The stock injectors you have now are high impedence and dont need one....however the 750cc injectors that you have are low impedence. So you'll need to get that wired up along with the hondata s200 to control the amount of fuel that is being dumped.

Almost forgot about that resistor box. Thanks for all your help fellas. I figured the S200 would allow for it to start. I have the rom emulator software to run basemaps with a Laptop. But I'm not sure where to find any basemaps.
