ok i brought this r33 rb25det manual, it is all standard.

when i got it home the engine light was on and it was running rich as hell to the point all the plugs had failed up, fill my shed with smoke that had smelled like fuel.

i went out and got a nistune 14 pin plug and some programs on the laptop to see why the engine light was on, but it would not connect to my ecu.

latter on i have found out that i am running a N/A auto ecu for a b33 rb25de motor.

could this be why my car is running so rich and the engine light is on.?????

i am going to go and pick up a standard manual turbo ecu for it this weekend

to see if that is the problem.

what are people thoughts

any help would be good help as i am new to the skylines. if it were a holden id have no probs at all

Certainly the non turbo ecu would be a main part of the problem. The non turbo injectors would surely be smaller meaning that more fuel gets injected.

That probably wouldn't turn on the engine light though, so there's likely another issue.

Did it run nice when you bought the car? Or just happen afterwards?

i have mate new belts including timing kit oil plugs all the usual stuff, i was going to change my 02 sensor to see if that was the problem as to why it was running rich, until i found out that the ecu is not the right one.

after i change the ecu this weekend my next step is to find out why the engine light is on

i am kind of hoping that it is on because of the wrong ecu

but having the non turbo auto ecu would be why she is running so rich???

      But seriously, can we ask for the results of the "tip a bottle of metho into a nearly empty tank" experiment?

      Hang on. Let me get this straight. The desire is to have coilovers, BC in particular, to be MORE comfortable on Sydney roads than stock suspension? Well, that's obviously not right. BCs have crude damping design at the very best, and typically hard spring rates. BC stands for Billy Cart. And then, the desire is to put in some shitty old worn out stockers, to get it blue slipped and then put the BCs back in? And then.....what? Not worry about getting pulled up by the Plod? Because you seem to have raised a worry about paying for engineering (which actually does solve all your legality problems) and still getting pulled up.... but the only problem there is that if/when that happens you have to show your paperwork at the inspection station. Whereas, if you just swap in borrowed shitty old stockers to get it slipped now, and then you get defected in the future, you have to go find more shitty old stockers then too. You course of action looks like this set of options: Buy brand new stock type dampers, and springs. probably cost a bit more than $1k all up, but will last for the remaining life of the car. Put them in, pass inspection, drive on them forever more. Hell, they could even be really nice Bilsteins and Kings or other lower&stiffer springs if you wanted. Get the car engineered as is. ~$1k. Buy new Shockworks coilvers (or MCA) and also pay for engineering. You're spending a lot more here. But these will be the best things that you could drive around on.

      Might be worthwhile hitting up Facebook's groups, I know most of them contain terrible people and scammers - however you might be able to find someone that's in Sydney with factory suspension you could purchase and/or hire. Just do not send any form of money anywhere, in person cash only.

      Thanks @Duncan Ride height is fine. I think it's almost stock tbh. Happy to share a pic. I don't actually have a regular mechanic as haven't lived in Sydney too long. Could you or anyone recommend any shops in Sydney?
