have you tuned the ecu to suit the injectors eg power fc have you adjusted the duty on the hand controler-

Yes, I have adjusted the injector settings ,but the duty not yet. How do i go by adjusting the duty on the hand controller.

Thanks.

Hey man

If you set the injectors up in the hand controller you would have set the scaling for the injectors (as a Percentage) and then you would have adjusted the lag/latency of the injectors (+ or - a small number like 0.12 or something). That should be enough to set your new injectors up for now.

When it comes to only being able to get shit fuel, i had a similar problem. If it is only a small small town, the fuel sells slowly and they only had 91, chances are that the fuel is shit. If you have the chance to travel a little further and grab some fresh 98 I would highly recommend it. I bought "premium" from the local servo in my little town and its was absolute shit.

When you are turning it over, are you getting ANY ignition at all? Does it even try and fire in the slightest or will it just turn and turn and turn?

EDIT: Have you set the base fuel pressure? Is it possible to just use the stock FPR for now while you try and get it running?

The injector setting are place in already 65 % and 0.20 ms thats the setting that i input. As for the fuel is real hard to get a higher octane, i would have to mix to get that rate.

Yes, i have ignition (checked by inserting the plug into the coil and place it near a ground). When I tried to fire her up, you would hear it firing up ,but after that she just turn n turn n turn. I also tried with WOT while cranking her up.

Thanks

Oh ok so you have spark. Sorry man I meant ignition as the fuel actually igniting. So it did that a few times and now you just have nothing? If you still have spark I really can't suggest anything but the fuel. How long ago did you get this 91 octane fuel? Also what is your fuel pressure?

If you can only run 91 fuel, you will need to take some timing out of the maps.

Also, what is the setting for timing during start? RBs like a lot, like 40-45 deg.

When trying to start after flooding, you need to just keep cranking - could take nearly a minute to clear the excess fuel. The engine won't start like normal.

I will try to change the fuel that i have in the tank , i belive it had the for month or so. The fuel pressure that i set on my sard reg. is around 50psi, but i notice once i stop cranking the pressure drops

slowly,would that cause less fuel or the duty cycle.

if the pressure drops..there is a leak..in your fuel supply... could be the cause of piston problems

I have check all fuel lines,fittings and on sign of leaks...could the fuel pressure reg. be cause of leaks.

I will be on the look for a new reg.

Thanks

      Wife wanted basket things in the wardrobe in our temporary house. Thought about ripping our the wardrobe and fitting the entire IKEA set, but it's a temporary house and we want to move in a few years. So IKEA advertises this as a 50cm unit, however the actually basket and rails measure 46cm wide. Only issue was depth, IKEA stuff is quite deep, where as the builder special junk is super shallow at less than 40cm. Send it, chopped the rails, then offset the mounting holes, job done, happy wife, less shit scattered all over the bedroom. Did the same to the other side too. Also drove the Skyline shit box today, dropped off oil at Supercheap Auto. I didn't realise they only now take max 2x bottles per visit. I visited 2x Supercheap Autos.

      Strange issue RB25DET wont start

      I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.

      The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?

      I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.

      I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
