Staying with the sequential system alright , Haltech and F-Con are very capable too
As an FYI the OEM 440cc Injectors are not characterised by Motec yet but a simple Voltage table will work(OEM Part Number is 23209-49025)
I found Injector Dynamics

ASNU

The complete list of injectors that Motec has characterized is found by loading a package based on the July 2015 or later 1.04 firmware and then looking at the pull-down list. When I do that, I see ASNU (11 models), Bosch (71 models), DeatschWerks (6 models), Delphi (2 models), Denso (53 models), Finjector, Five O Motorsport, Fuel Injector Clinic (2 models), Fuel Injector Development, Grams, Hitachi, Injector Dynamics (4 models), Kawasaki, Keihin (13 models), Kia, Lucas, Magneti Marelli, Mitsubshi (3 models), Moran (9 models), MPC, Nissan (3 models), Precision (2 models), RC, Rochester (2), SARD, Seimens Deka (19)Weber (6), XSPURT.

You need to talk to one of your local dealers to organise for the injector to be characterised, they will send the injector to us, we do the testing, and then send it back to the dealer to return to you. If the injectors are factory standard, unmodified and have the standard part number on them, then the characterisation testing is free of charge. if they have been modified, then there is a charge levied. You may also have the cost of the postage back and forth for the injectors as well.
