I think it will work but you may need to code the immobiliser to make it start-able.

The immobiliser code is the 4 digit on a metal plate in one of your keys. if you don't have it you're out of luck. pray that your existing key(s) never stop working/damaged/lost

you can buy from Nissan, cost very expensive of course

having an auto means ECU choice is basically very limited. probably the easiest is having an SAFC (piggy back computer) so you can somewhat tune your air/fuel ratio to a certain degree. it won't be as good as a replacement ECU but it is possible...

you should have bought a manual in the first place. Sell it and buy a manual, then you can easily get an Impul ECU, or PowerFC, etc.

I bought an auto cos I don't plan to modify, and the missus can drive it too.

yeah i've kind of grown fond of the auto somewhat..

i was thinking i will just go a piggyback..

i noticed haltech had a few which on there internet site were for a 04 350z.... im guessing will work on our cars?

is the imobiliser only armed when the lock/unlock is used on the stndard key.. as i have an aftermarket alarm system (mongoose M80) which has its own 3pt immobiliser.. so im assuming the standard immobiliser has been dealt with? (or not :S).. or is the standard immobiliser disarmed when the key is inserted into the ignition?

if i were to go with a piggyback would this avoid all issues with the immobiliser?

thanks for all the help, sorry if i seem like abit of a dimwit when it comes to this as i havent dealt with ECU's before...

no idea. ask the person who did your immobiliser.

mine is aftermarket 3pt immobiliser, the factory FOB key still work but it will not arm the alarm.

the FOB key has a transponder in it that transmit code to a receiver in your key barrel. if the code matches to the code programmed on your ECU, it will start the car. if not the engine will turn a bit but won't start. so even if you have an aftermarket 3pt immobiliser, the ECU code and your key is a different thing to program, nothing to do with the aftermarket immobiliser. so it's an immobiliser within immobiliser, or a secondary immobiliser thing. very complicated.

piggy back like SAFC only taps onto your a/f signal so nothing to do with immobiliser.

no idea about Haltech, etc. i'm no expert on ECU, i'm just about as dimwit as you are

      Steps to DIY sanding car back ready for respray....

      Sounds good. Provided the panel is flat/level I'd be happy to start the painting process.  While you are learning, for sure you could do this. Its only paint, you can always sand it all back and start again. Its only your time and money on materials, but while you're learning, really its time and money spent on your education.  Once you know how to do this bodywork and painting, you won't want to waste your time and money on frivolous activities lol.

      Yep I will use a guide coat after putting filler, I will do it on the whole panel as I'm a beginner so chances I've made quite a few errors. In that photo, I think that was a low spot, I just for example said to pretend it's flat but I will put filler + guide coat after to assess where I'm at. Yep with that picture, the panel is wet as it rained when I took the photo. But all those scratches are completely smooth, I went over it with 240 grit and can't feel it, even with my nail digging into it. I was legit thinking to buy a 2k can and spray primer to see how it turns out but then thought to myself it's going to be a mess doing it haha. Good mention there. Thanks for all that info I think I know what to do next.

      Prior to laying down the primer, you need to make sure the surface is completely level. For example, based on this picture, I strongly suspect that the areas marked in blue are higher then the area marked in green.  If you spray primer over this entire area, then paint and clear it, the finished result will 100% show the low area. It will stick out like dogs balls. Unfortunately the paint won't magically level out the low areas as you lay it down.  Without seeing it in person, I expect that the green area will need to be filled, then use a guide coat and check that the entire repair area is level with a large sanding block.  With this picture, are you saying that even though you can see the scratches, the panel is in fact completely smooth and flat? If this is the case sure you could prep and paint it as it is.     The picture with the paint you described as blistering, it's hard for me to comment on from the photo alone. It looks like the panel is wet? Dunno, looks strange. Does the panel feel as smooth as glass when you run your hand over it? **** Going back to your question again, generally you would only sand the primer if you made a mistake while laying down the primer.  If the panel is prepped properly and you lay the primer down properly, you should not need to sand the primer.  This wouldn't work - Don't prep the panel. Spray primer and see how it turns out. Sand the areas where the issues appear. Spray more primer and see how it turns out. Sand the areas....... Yeah you'd go round and round in circles getting no where.

      That's sick, thanks for that, mine has much the same mods on a 400R. I just don't have the heat exchanger yet.   Might be worth a trip down the M1 to Syndey for a tune.
