Guest bastaad525 Posted November 18, 2003 Share Posted November 18, 2003 http://hybridz.org/phpBB2/viewtopic.php?t=28107 a thread I posted about this very issue the other day... it is really odd, but it seems very common... whenever a turbo car starts cutting out on boost or at wot like that, for some reason simply unplugging and replugging the ECU will often fix the problem. *shrug* it IS nice when it's something simple like that though....

Guest bastaad525 Posted November 18, 2003 Share Posted November 18, 2003 huh? what? hey I'm not trying to say it was my idea or anything... if that's what you mean. I dont remember who, or how many of you, suggested that to me when my car first started acting funky... it just seems really odd that it works.

cygnusx1 Posted November 19, 2003 Share Posted November 19, 2003 Sorry but I think I've been connecting and disconnecting ECU plugs the longest....! Just Kidding.. I am sure it has nothing to do with resetting the ECU and everything to do with resistance values of the crappy connections. Link to comment Share on other sites More sharing options...
Len Posted November 19, 2003 Share Posted November 19, 2003 You know if you unplug then plug back in the connector to your ECU. It seems to clear things up!!!!!!!!!!........ ...........Hmmmmmmmmmmmm. Sorry guys had to say it too! But really; it got to the point where I resoldered all my connections trying to find the reason why my car started cutting out and running crappy at WOT (or trying to get there). Even the mechanic I bought my Z from three years ago told me if it runs crappy wiggle the wires connecting to your ECU. It works, I notice it more in the winter than summer. Be sure to brace yourself if your driving and you wiggle . Because when I bought the car I had to repair the windshield due to previous owner wiggled while driving and his foot was still on the accelerator :malebitchslap: I guess we just need to remember that these cars (and wires are over thirty years old!). Another reason to convince myself to pay $1,400 plus for a stand alone FMS.. Link to comment Share on other sites More sharing options...
fl327 Posted November 19, 2003 Share Posted November 19, 2003 anyone notice its the ones that swap l28ets that have to do this every so often, reset the ecu i mean. Its our faults, we are the ones who actually disconnect the wiring in the first place!!! Link to comment Share on other sites More sharing options...
yo2001 Posted November 19, 2003 Share Posted November 19, 2003 I have to wiggle my connector every now and then Link to comment Share on other sites More sharing options...
Len Posted November 20, 2003 Share Posted November 20, 2003 Now fl327; I don't want to poke holes in your hypothesis but I still haven't ever removed my engine its still in my 83 280zxt. And I still need to wiggle my cable... .............yo... I didn't mean it to sound the way it does. But after I read your last post... ..I just hope people didn't just only read these last posts or else I think they'ed get the wrong idea. Link to comment Share on other sites More sharing options...

fl327 Posted November 20, 2003 Share Posted November 20, 2003 ok fine, zts and zxts are known to have intermittantly faulty efi wiring connections that manifest themselves in the form of the "impossible" problem, also referred to as "mystery turbo death" that is remedied by wiggling, or cleaning and reinseration of the ecu molex ports. happy?

cygnusx1 Posted November 20, 2003 Share Posted November 20, 2003 I am working on a procedure for wiggling the connectors....I'm on page 87 and should be ready to post soon... Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted January 2, 2004 Share Posted January 2, 2004 First a contraction for ease of typing: OOYA - Object of your affection/aggravation (whichever is more appropriate) Rules to live by when wiggling your connector: Be sure to let the OOYA know you intend to make her PURR (until you really put the hammer down and then expect her to ROAR), and that this won't hurt a bit... Not on public roads or in public... Don't be looking at anything other than OOYA when wiggleing because if the said object catches you said object may throw a fit and become even more of a headache... Make sure your connector is going in the right hole - many times you will get serious bucking/backfire when not connecting properly... Wiggling only goes so far - for maximum effect/contact you'll have to pull out and push in a few times... OK - MORE than a few times... Application of appropriate agents will help in this process, especially if the object of your affection is balking... Keep repeating until OOYA lets you know by her behavior you've reached a satisfactory conclusion (or you have lost all desire/ability to try again)... When finished, a nice cold six pack and a good sandwich caps the whole experience while you congratulate yourself on a job well done... After that - a nap maybe...

datsunan Posted May 20, 2004 Share Posted May 20, 2004 I was so happy to find someone with the same problem as me and that there was an easy fix. Unfortunatly I had no luck with unplugging my ecu to get it to run right. I'm so frustrated, I just spent a ton of money on this car and broke it in slow now I want to go fast and all I get is a flat spot when it should be slamming me in the seat. Do you have any other suggestions for me? Do you know what is happening when it does this ie, ecu cuts fuel, changes timing or is it a bad connection? I put some di-electric grease on the connector and it still does the same. Thanks Paul Link to comment Share on other sites More sharing options...
twoeightythreez Posted January 25, 2007 Share Posted January 25, 2007 Another reason to convince myself to pay $1,400 plus for a stand alone FMS.. You don't HAVE to spend that much for standalone... My MS-II (Fuel and spark) cost me $300, all I had to do was (yipe) build it, wire it, install it, and tune it...no big deal Link to comment Share on other sites More sharing options...
thehelix112 Posted January 25, 2007 Share Posted January 25, 2007 IMHO with the advances that are being made constantly to the megasquirt system, and considering how much the rest of the car is worth, it seems absurd not to spend the money on a stand alone system.

Careless Posted January 26, 2007 Share Posted January 26, 2007 Just want to follow up here...WHAM!@ Full power again all the time!! Cooooooool! I see you like George Michaels.

wigenOut-S30 Posted January 26, 2007 Share Posted January 26, 2007 If you guys look, this post was from 2003, Garrett has since put SDS on the car has is making in eccess of 460rwhp.. I think he solved his problems lol..But yes.. standalone ECU is the way for our Cars indeed. I cannot wait to get into Megasquirt land.. Link to comment Share on other sites More sharing options...
thehelix112 Posted January 26, 2007 Share Posted January 26, 2007 Hahah.. good point. I was scratching my head wondering about the safety of making that power with the std ECU. Hehe. Dave Link to comment Share on other sites More sharing options...
