Heya, after some suggestions.

My 32 is running lean. On the dyno it was idling at like 18 (a/f) and im told it should be at around 12

The ecu was remapped in Japan and im guessing to suit their 110/115 octane fuel. I think that is more than likely the problem, although have not checked fuel pump yet. Injectors are 650cc so they should be ok i guess.

It's going in on the dyno again to see if the problem can be located.

If the ecu does need remapping (which i currently cannot afford) can anyone suggest a cheaper, short term alternative?

Am using octane boost at the moment.

Cheers :)

I have been trying not to drive on boost.

Those ratios sound right (i lost my dyno sheet).

I spoke to my mechanic and after giving him more info he thinks its just the fuel pump, so looks like i could be wrong and ecu may not need a remap!!!

Will check pump, if not pump will replace ecu with stocker.

Cheers :)

Wanna know some freaky shit, went to hyperdrive to source the problem and she's running no where near as lean as the previous dyno stated (that was at a workshop im quite unhappy with that will remain nameless). Running on the same boost today as she was the previous dyno run 2 months ago- nothing had been changed inbetween!!!

Boosted her up a bit and wallah, she's now running rich.

Boy is that a relief. Muchos gracias hyperdrivers =)

    • This could be sold and shipped to the US for many gold pieces. RMS has no say in that. Ask various Western Sydney inhabitants how it works.
    • Ha ha ha, mine loves to spend, all on the dogs (they're our kids, and her spending would likely rival that of some people raising children!) the only benefit is, her spending is tax deductible as she runs a business in the dog industry 😛 The above all means she can spend race car budget quicker than I can. 😛 That and a lot of the things I want are very expensive, and I can be a bit "you want how much for that?!" And at other times overly impulsive. Or I start the w days of research, get to day 1.5 and get really annoyed that no one will advertise actual specifics and it's just marketting BS and I go "well, now I don't want anything to do with that now!" Also I hate paying lots of money for something I can make from $50 in materials. Then I get the shits halfway through making things and wonder why others who just buy parts have more fun... 😛  
    • Their 240Z with the RB26 would be a real nice thing to have in a garage to come out for an occasional weekend cruise It's such a cool thing in so many ways Sadly, we have a blue 240Z shell that I walk past every day, just sitting outside a shed at work, it has been slowly disintegrating and falling apart into the ground for the last few years, the owner cannot be found, and I am unable to "claim it" I've been told by work and the RMS, the rust in the body is excessive though, and it has had most of the salvageable stuff, like panels, trim and switch gear stripped off it over the last year or two, work keeps threatening to put it in one of our metal scrap bins, I wish they did though, as it makes Mark sad walking past it  
    • Good tips, I like it! 😂😂 My wife is a LOT more frugal than me so it's only me we need to worry about! A splurge to her is buying 2 pairs of socks in one visit at Kmart!
    • Haha, the appropriate response to the question "Is this new?" is "I've had this for a while.". With the unspoken small print that a while may be the time since this morning or five years ago   And to be fair I learned that from the best, i.e. my wife. Because it goes both ways.
