Scott-tt Posted November 15, 2015 Share Posted November 15, 2015 (edited) I have a problem where only 4 out of 8 injectors are pulsing could I simply wire them to pulse in 2 groups of 4 instead of 4 groups of 2 this is for a 1uz in a mkiv. The all have switched power from mrel but only 3456 have ground from ecu to make them pulse from what I've read the capacitors go bad in the ecu causing this if this fix won't work I'm going to have to source another ecu or get mine fixed also does anybody know someone who can repair ecus I feel like every Sunday night I'm asking more questions after weekends of diagnosis now lol Edited November 15, 2015 by Scott-tt (see edit history) Link to comment Share on other sites More sharing options...

Scott-tt Posted November 15, 2015 Author Share Posted November 15, 2015 Save yourself a lot of bother and get another ECU. I've sent some emails and I'm going to phone around tomorrow and see who has one for sale. There's none on eBay so I'll try the soarer breakers on eBay I'd much rather just get a replacement unit Link to comment Share on other sites More sharing options...
Shane Posted November 15, 2015 Share Posted November 15, 2015 (edited) The det3 piggyback can be used in fuel implant mode Scott, may be worth a look. Batch firing as you describe could work if you can configure it right, 1jz engines used this method and the ecu has only 3 injector drivers.
