GTR ecu's have low ohm injectors, which send a huge amount of current to open the valve, but only needs a small amount of current to keep it open. this method of injector driving can cause high ohm injectors to operate erratically, I would try using a GTX ecu to test it out, or Low ohm injectors atleast.

GTR's have a resistor box to match the low ohm injectors. the ECU itself recognizes a high ohm signal only.
Edit: just to clarify- i have been running the GTR ecu for some time now running several different sets of high ohm injectors. no issues to date---Has ClubProtege helped you in someway? show your support by Contributing--- Click Here---

not to start an argument (seeing as it seems not to be your issue) but the resistors are there so they can use the same transistor as they would for a hi ohm injector, this says nothing about the control algorithm used for the Low Z injectors, infact the ability to control an injector in this manner is the only benefit of using low Z injectors in this application. So while I disagree with you on the how the GTR ecu works, its kinda pointless for this thread."Discontent is the first necessity of progress."

changing the injectors/swaybar/front struts before it see's the road again
so....... maybe springtime---Has ClubProtege helped you in someway? show your support by Contributing--- Click Here---

^ the car hasn't been at skunks for ages now.
it runs & drives. i just refuse to put it through a salted winter. (which is understandable)
put the back tires on some mover dolley's from harbor freight. planning to grab another 2 of em for the front. - sure makes moving the car around in the garage ALOT easier.

sweeet! I didn't realize you were running a 3rd gen subframe, I love that they've updated the sway bar mounts with 2 bolts vs the slip clamp lol...can't beat common sense lol. Silly Mazda.-Jack

You mentioned that you didnt have to completely drop the sub frame. Did you just loosen the subframe and guide it out?
And did the civic 22mm bushings work?My car is a Vazondissan. Part Nissan. Part Mazda. Part Ford. Part VW. Part Honda.
