Honestly I did try that it didn't make any difference. I tried turning the car off then back on then rereading it then clicking air fuel meter and then changing it and it is still wouldn't write it. And just to clarify do I need to click the update button or write all?

Ok. I will give that a try. I told the guy that has been trying to tune my car and he noticed it as well when he tried to update the air fuel meter it wouldn't take it for him and gave him the same error.

Update:

After some ECU pin testing for backup power loss ( Thanks to PaulR33 for the idea) i found that I had none. Swapped the relay with a known working spare and no change. Went to fuse checking for the 1000th time, and I actually found one of the fuses for Engine Control in the engine bay was blown. This was a recent occurence, because I have been checking them periodically. After replacing that one, I continued to re-initialize the FC and re-load my map and settings. Things were looking better b/c the airflow write error didnt show up. I was in the process of cleaning the plugs and decide to check for spark for good measure and noticed no spark. I went back to the fuses for kicks and now the other Eng Cont. fuse was blown. I replaced that one and checked the other one, it was ok still. Spark came back at this point. Finally I was able to actually try and start the car with all of the settings saved in the FC and the car finally started! Now back to point A. Get the car tuned.

THANKS TO ALL FOR YOUR RESPONSES AND INPUT! This is the best source for Skyline owners needs!

And im not sure if anyone has found or linked this site, but I found some rather useful info on here:

It is at a slightly higher rpm. I believe it to be due to a fuel issue because I don't know the correct injector lag time so I'm leaving that up to my tuner. My short little drive was my test to make sure there were no other issues that needed to be addressed before I get it tuned. It stayed on the rich side during that sound and i know that my plugs were a little fouled from earlier testing. New ones going in asap for safe measure.

So i have one final bug to work out. On my hand controller i have THRM highlighted. I have read that it should be reading 3.6-3.7 volts. It currently reads .06v. How do i fix this? The trac light is on also. Any ideas. I found a thread on here but the link won't get me to it so I'm not sure how they fixed the problem.

    • Yeah, the latter. No diff should have a centre replaced without checking clearances because its unlikely to be the same as whatever came out. Not that that stops most people just checking a new centre in
    • Major thread necro but how bad of a job is it to DIY? Looking at it online it looks like if you reuse your ring and pinion as long as those are in good condition it should be fine to just pull the axles/front cover and replace the diff that way? Or should I be replacing everything and doing preload measurements/gear mesh testing like the factory service manual mentions for the rear diff?
    • in my list I had the R33 GTR as the best Skyline. Infact I had all GTR's (33>34=32), the NSX, the GTO, the 300ZX, the 180SX, the S15 better than the FD RX7. I had the MR2 and the A80 as 'just' better. I also think the DC5R Integra looks better but this is an 01 onwards car. I also think the FC>FD. It's almost like aesthetics are individual! The elements @GTSBoy likes about the FD and dislikes about the 180 are inverse in my eyes. I hate the rear end of the FD and it's weird tail lights that are bulbous and remind me of early hyundai excels. They are not striking, nor iconic, nor retro cool. The GTO has supercar proportions. I maintain these look much better in person (like the NSX) especially with nice wheels and suspension which is mandatory for all cars pretty much. Some (or all) of these you have to see in person to appreciate. You can't write a car off until you see one in the flesh IMO. Like most people we probably just like/dislike cars which represent certain eras of design or design styles in general. I also think the 60's Jag E type looks HORRIBLE, literally disgusting, and the 2000GT is nothing to write home about. FWIW I don't think the Dodge Viper Gen1's have aged very well either. You can probably see where I rate bubbly coupes like the FD. I know we're straying now but the C4 and C5 absolutely murder the Viper in the looks department as time goes on, for my eyes. Wouldn't surprise me if people who love the FD, also love the MX5, Dodge Viper, Jag E Type, etc etc.
    • I used to hate R31s, and any of the other Nissans that led up to it, and any of the Toyotas with similar styling, because of the boxiness. They were, and remain, childish, simplistic, and generally awful. I appreciate R31s a lot more now, but only the JDM 2 door. The ADM 4 door (and any other 4 door, even if they are unique compared to our local one) can eat a bowl of dicks. The Aussie R31 is also forever tarnished by their association with stereotypical bong clutching Aussie R31 owners of the 90s and early 2000s. I think the Nissans of the 70s (other than 120Y/180B/200B) are far superior looking to the 80s cars. The 240K era Skylines are boss. The same is broadly true of Toyotas. Hondas don't ever register in my thinking, from any era. Mitsus are all horrid shitboxen in any era, and so also don't register. Subarus are always awful, ditto. Daihatsus and Suzukis also don't generally register. They are all invisible. I think the SW20 MR2 looks fiddly. The 3000GT/GTO is like that but way worse. Too many silly plastic barnacles and fiddly gimmicks ruined what could have been a really nice base shape. Kinda-sorta looks like a big heavy ST165 Celica coupe (and I'm not sure if that's a good thing or a bad thing). I think the 180SX is dreadfully bland. It's not bad looking. But it has no excitement to it at all. It's just a liftback coupe thing with no interest in its lines, and bad graphical elements (ie wide expanses of taillight plastic on the rear garnish). The S13 Silvia is a little better - getting closer to R32 shapes. But still....bland. S14? Nope. Don't love it. S15...a little better. Probably a lot better, actually. Benefits from not being like a shrunk in the wash R34 (where the S13 was a shrunk in the wash R32 and the S14 looked like a Pulsar or something else from the stable on Nissan mid 90s horrors). The Z32 was hot as f**k when it came out but hasn't aged as well as the A80. Keep in mind that I think the R33 is the most disgusting looking thing - and out of all the previous cars mentioned is objectively closest to my precious R32. It's just....real bad, almost everywhere you look. And that is down to the majority of what was designed in the 90s being shit. All Nissans from that era look like shit. Most other brands ditto. In that context, the FD absolutely stands out as being by far the best looking car, for reasons already discussed. Going behind the aesthetics, the suspension alone makes it better than almost any other car.  
    • If they just called it the "Mazda Tiffany", it would have been spot on.
