Powerfc In Auto R34 Gtt

The R34 GTT ECU and TCU are contained in the one unit.

I have had my transmission rebuilt and I'm told it can handle 300rwkw without needing the soft landing, ie timing drop, that the stock ECU does.

I was reading Sydneykid's thread on the SITC and thought perhaps I need a piggyback ECU that goes between the stock ECU and the coils.

Which ones do this? Unichip?

Then I had a brain wave.

What if I get a PFC and plug most of the wires into it so it can run the engine. Then run extensions to the signal wires that the TCU requires to run the auto transmission over to the stock ECU so that both the PFC and the stock ECU will be receiving input from all the sensors.

Any wires that are sending information from the stock ECU to the engine will not be connected. The wires that send information the transmsission would be connected.

What do you all think?

adam, the pfc will run an auto car. The only problem is flaring on the shifts as it doesn't pull back timing for the shifts.

I can't see your theory working but I am waiting to be proved wrong. :)

Why can't you just wait for darkhalf's boards? hehe

I did think there shouldn't be any clear reason with enough wiring to run both ECU's simultaneously it shouldn't work??

I haven't seen any previous mention of this on here..

Any reason why?? other than the ~$1000 pricetag of course. I guess for R34 they have a slightly different version of the autos.

The shifts wont flare on my car because my gears changes are too tight.

I know there is the odd R33 with PFC but don't R33's have a separate controller for the auto? What happens if I press the button on my steering wheel with a PFC and nothing else? Probably nothing cos it wont be connected to anything.

Adaptronic 440. It has a lot of integrated features which can save you money, ie boost control, serial input for a wideband, programmable outputs, plus some neat adaptive tuning features, ie with a wideband it can automatically alter a fuel map (though best results are done manually). Plus theres a flex fuel functionality if you're interested in e85.

Just be mindful that you're starting from scratch with ignition and fuel maps, so the learning curve is very steep. Although there are base maps available, they arent very good. You'll need to learn how to tune yourself, even in conjunction with a tuner.

i was looking at other options to have a true 4" intake without going down to 3" for the z32, or not having to run a z32 in the cooler piping thats all

Nistune is not limited to running Z32 AFM. You can install an R35 AFM sensor into a 1000mm drainpipe if you want and set Nistune up to run with that.

      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.
