I have a 1981 280 ZX which has fuel injection. I know that this forum is used by mostly 240-280Z owners and that the ZX's are the black sheep of the Z family. However if anyone can look past the addition of the extra consenant (X) and comment on my question, it would be greatly appreciated. My car has an automatic transmission, so great gas mileage is not to be expected aka. 3500rpms @ 60mph. I was wondering if there is anything that I can replace or clean out in the fuel injection side of things that could help my fuel economy out. I was also thinking about trying to find a 5-speed to replace my 3-speed auto out with. I would also be interested in knowing if the 5-speed…

1975 280Z - could use some advice on how the control unit (fuel injection brain) hooks up...??? There are two white wires with female butt connectors coming out of it that are not connected to anything. It will start and idle, but accelerating makes it run like it's getting lots of air, but no fuel. Four of the injectors seem to be working, but two don't. Any suggestions would be welcome! Thank You!!!

What is the Hasegawa Power Services injection system all about? Of course, I can't read a damn thing on their web site...I am a FI fan and have often wondered about an 'unmetered' air flow and it's possibilities. I clicked on the link and said, "OMG! here it is!" What do you know about it? What regulates the injectors? Are there individual butterflies? They have a black box pictured...does it replace or add on to an existing CPU? I would think the existing brain would be worthless in this system. Is it RPM based? Is it vaccuum based? Oh, yeah.....and......(what does it cost?) steve77 soon to start a 240 FI project

I'm probably going to make a purchase tomorrow unless someone tells me that these injectors are bad. However, here are the specs of the fuel injectors for my '75. Aechlin (ecklin?) Fuel Injectors by Dana Corporation They are around $75 each at my local Napa shop. Courtesy will sell original injectors to me for around $100 ea. This is something I don't want to skimp. Someone told me that the OEM FI's are Bosch. What do you guys think?

'77: Normal, every single time until today: Put it in neutral, turn the key, listen for FP, hit the ignition, starts immediately and assumes a cold idle around 1200 and I usually let it idle for 5-10 minutes before driving. No smoke. Note: My foot never goes anywhere near the throttle during all this. Today: Fired right up, but REALLY rough and chugging. Sputtering up and down around 400-500. Seems to be missing really bad and had a tone to it (I had the hood up) like one of the cylinders was hitting something. Smoke starts coming out the tail pipe. I rev it up slightly with the linkage, but it does not smooth out. It continues the same skip. I reved it to mayb…
