Timing Question

[Nige1]

Hey guys i know this is bit of a hard one but does anyone have a guide for all the correc timing for r33, i wanna check mine and see if it normal. Also is 7/11 dodgy for fuel i put some in and my car just went shit idleing, smoke, not revving past 3 rpm but after injector cleaner it seems okay but engine lights still on

The only timing you need to be concerned about is base timing at idle. In general, the ECU expects the engine to idle with timing around 15BTDC. It assumes that this is set correctly, and all other timing is based on base idle timing being correct.

As for the dodgy fuel, if you filled up shortly after they received a delivery, then you might have got some crap that was stirred up during the tanker filling the underground tank.

Not entirely true. The timing at idle will change. You need to disconnect the TPS (from memory) on r33's to put it in base idle and it should sit at the base timing then. As long as your idle isn't going nuts it should be fine. 15 degrees is what it needs to be set to

If you have a STD ecu then it takes care of the rest. If not you will need to take it to a tuner to get the timing modified

Sounds like you have AFM issues. Check the AFM plug. Do you have an oiled air filter?

I just have an apexi pod filter im now gettin terrible back fire nd lack of performance but at least its drivable after being warmed up

So is it spitting out black smoke and running rough only when it's warming up?

[Nige1]

When i first start it up cold it idles fine but if u touch it accelerater it wont rev past 3 rpm n just backfires heaps and after warming up it has power loss and lots of backfire

I'll go with AFM needs cleaning, Soldering or Replacing.

Maybe even just unplug it, clean contacts and try again.

Cleaned it, cleane plugs i dont know how to resolder it and i cant get the top off

It's for RB26 MAFs but it should help.

You have to cut the sealing bead around the lid with a Stanley knife.
