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

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
