Fule injector recall & wiring: Is the wiring part mandatory? Better to avoid or no?

Hello all, looking for clarification on the infamous fuel injector recall/campaign & whether just replacing the injectors is enough or if the wiring changes are also mandatory.

SHORT VERSION: As many may know, the Z31 has an old fuel injector recall that involves both new injectors and re-wiring of the firing order. Some people like the firing order change & others do not from what I've read. I'm looking at an '84 Z and realize that the injectors appear to have been replaced, but no wiring work was done.

In short: Does it matter that the wiring part of the recall was not done & only the injectors/rails replaced?


Background for those who care:

I'd posted a thread on getting an '84 NA & found out the fuel injector recall/campaign was never done. I was lining up to do it locally when the seller pulled the plug & wanted to do it himself. Never heard anything & thought the deal was dead.

Anyway, got a call the other day- the owner says the recall was done & sent me a nearly illegible receipt from the dealer listing 2 fuel rails & an injector assembly. Might be 1 or a package of 6. I can't tell. I've contacted him for clarification.

One thing I can tell, however, is that the wiring part wasn't done. Is this a good thing or bad thing? I've done some research, but aren't sure.

I am prepared to travel at no small expense and see this car in person. If it is in the condition claimed I would go ahead with the purchase. Never thought I'd spend so much time on a diversion, but here I am. Thanks to all.

Wow, that is interesting-- can you elaborate?



Never thought of that. How does wiring save labor? The car I'm looking at did not have any wiring done, which is obviously even less work.

Sorry if I'm a little slow, but what the purpose of the wiring and is it actually better that it was not done?

Thanks!

well I had the recall done to my 85Z31 turbo and the car run differently it lost his pep and power. I went back to the dealer and ask them why they said it needs other "things" so they put an MAF at a charge and still run the same way. If I have known that my Z will not be the same I would have never done the recall.

Now that I have confirmed the injectors were done I am scheduled to go look at the car in person after Thanksgiving. If it is as I hope I'll drive it home. Just gotta find a storage place for the winter, though as the 335xi is not staying outside!
