Hey guys, i have another Build update!

Since our HPFP can't seem to support 100% E85 on 22psi, i needed alternative fuelling support.

Fuel IT just released their CPi Kit, i grabbed one (to be precise i bought their B58 950cc kit as it comes with everything you need plus an extra fuel hose that you can just discard and i chose not to purchase the chargepipe meth bung adaptor as my FTP chargepipe has 3 1/8 NPT fittings).

I will post some photos but its a relatively easy setup, screw the injector into your chargepipe, plug the 5/16 fuel line adaptor into your low pressure feed, and connect the 4an braided fuel hose between the 2.

Electrical Setup:
since the B58 kit comes with the JB4 FSB which is used to control the injector, simply find a ground terminal for the ground wire, 1 wire will not have a Dsub pin crimped on -- Just leave it be. plug the remaining wires into your jb4 as per the JB4 WMI FSB setup, i.e Red wire into a vacant Fuse slot in the fusebox (ensuring it has the electrical connection) the 2x dsub pins slide into the jb4.

JB4 Setup:
(set meth scaling to 100)
go into the WMI settings and Enable "WMI Pump PWM
then go to user adjustable settings and start off with Fuel Bias 50 and no less (if using the 950cc injector - ultimately if you want to run this much boost on EWG, 550CC is a MINIMUM!) basically from here do some datalogs and see how your HPFP handles if it drops by 100psi or more increase the Fuel Bias as needed, set mine to the following
3000rpm = 100
3500rpm = 100
4000rpm = 100
4500rpm = 100
5000rpm = 100
5500rpm = 100
6000rpm = 100
6500rpm = 100
7000rpm = 100
7500rpm = 100 (not that ill ever reach that rpm).



---- Terry from BMS is adding support for CPI and BMS PI controller to the firmware, as of originally writing this post the JB4 wasn't controlling the CPI properly, this firmware should be released soon check the N54 page for it.

-Just adding a note the 950cc injector is actually too much for the engine, changed to a 550cc injector and it has fixed my scalars going negative.
