hey ppls.

All you tuners out there, what AFM ratio are you running at cruise?

I think mine is about 13.2 : 1

I get crap economy  could this be why?

I have stock turbo, 260 poncams.

PFC

The Stagea runs 14.7 to 1 at closed loop cruise and idle. The R32GTST race car also defaults to 14.7 to 1, but it doesn't do much closed loop running or cruising.

It's been a while since I looked, but I can't remembr seeing anywhere in the Power FC mapping where you can change the closed loop aim from 14.7 (even with a Datalogit). So if yours is really at 13.2, then it's most likely not running in closed loop and the mapping changes will have some effect. But if it is running 13.2 in closed loop, then the mapping changes will have zero effect.

:D cheers :D

i came off 460km's to my tank with room for more last week ;)

admittadly im on the stock ECU at present but that means im staying off boost, and never going above 3000rpm... boost is the enemy of fuel economy

i should have tried that while i was using the PFC etc. Best i got then was 330 but that was with a stuffed O2 sensor and lots of boosting :D

K

Now I've heard a horrible story about leaned out cruise mixtures can burn out exhaust valves on engines with big cams.

Not sure whether I'd call my 260 Poncams big or not, or whether I'd call 14.7 that lean.

Any thoughts?

My yellow light normally lights up quite early about 40l used then I just fill it up on the E , I will fill around 45-47l max haha.

I thought I was doing bad with those 350km (I'm a student so not much highway driving) , since BP Ult petrol price went up to 126 cents per litre!!! ridiculous (In Perth)

Is Julian Edgar quoting 16:1 for a nissan? Is that cruise or lean cruise? Most cheap (non sequential) aftermarket computers wont cope with those kind of numbers. We continue to run lean cruise in most holden v8's with durations up to about 220deg at 50 thou as a rule of thumb. But this is only with sequential ECU's.

    • You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways. 
    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
