Message	..doing this mod the long way, the short way, and the ECU way? [ http://www.twinturbo.net/nissan/300zx/forums/technical/view/1013303/The-simplest-mod-so-far-switched-power-injector-rewire.html ] Sorry to bring this up again, but all these varying "switched power injector" methods are starting to bug me. =) Which one is best and why? - G.

As I said, the current to ECU pin 58 is .86 amps - DVDBURN (MD) 15:03:33 11/10/10 If there is no current flow to the injectors when the car is - not4resaleZ 15:51:12 11/10/10 The mod is to prevent electrolysis. - DVDBURN (MD) 16:11:38 11/10/10 I agree, the unwanted current is bound to be very small, - not4resaleZ 16:35:47 11/10/10 so why would anyone do it the long way ? - TTkeeper 22:57:32 11/09/10 Can an electrical expert please explain the pros/cons of... - Gromit 04:26:06 11/10/10 My look at it. - DVDBURN (MD) 06:41:25 11/10/10 You can still solder it without taking apart the connector - John (MD) 13:43:06 11/11/10 Thanks for voting this to FAQ everyone. - DVDBURN (MD) 06:42:17 11/10/10 It's already been voted into FAQ, but..... - Woody75 (Denver) 12:07:45 11/10/10 Re: It's already been voted into FAQ, but..... - Eric(FL) 12:47:21 11/10/10 That's a very good idea!!! - DVDBURN (MD) 19:09:34 11/10/10 There isn't any fault code that's going to keep a car from - DVDBURN (MD) 14:57:57 11/10/10 Yeah, after reading what's actually being done, I agree. (n/m) - cherryz 21:36:35 11/10/10 That is almost too easy, thanks! (n/m) - whip 15:25:51 11/10/10 that's actually so easy that i'm going to do it - KasbeKZ(VA) 19:09:00 11/10/10 Do like Eric suggested. - DVDBURN (MD) 19:17:08 11/10/10 what do you mean? - KasbeKZ(VA) 19:28:14 11/10/10 Yes. If you do this then no worries about the ECU memory - DVDBURN (MD) 22:47:42 11/10/10 i think i understand - KasbeKZ(VA) 00:08:26 11/11/10 Yes, that's correct. (n/m) - DVDBURN (MD) 00:50:48 11/11/10 nice. how about from the clock? - KasbeKZ(VA) 09:07:15 11/11/10 Getting voltage at the clock should work. (n/m) - DVDBURN (MD) 16:05:16 11/12/10 At that point, you almost have to consider... - CoHPhasor 23:16:24 11/11/10 Thats what I was thinking. Maybe a hiden manual switch. - greyzx (now blue) 13:51:24 11/12/10 You could put a switch in place of the quick connect - DVDBURN (MD) 16:03:00 11/12/10 Sigh... Maybe I'm missing something here... - Gromit 17:30:03 11/12/10 The thing I don't like about the other way is that - DVDBURN (MD) 23:51:19 11/12/10 Thanks Gary.
