I currently have a R33 GTR with a Autronic SMC ECU and Autronic CDI.

I have purchased a new engine loom as the one in the car is a total mess!!!

I know that I need to hack into the new loom to install the Autronic ECU and CDI but was wanting to know peoples opinions on a Power FC over what I currently have?

I am only looking at the Power FC as i wont have to hack into the new loom as it is a plug in.

If I was to keep the Autronic, is there any other option to modify the loom rather than destroying the new one?

Cheers in advance

Rewire the whole thing, all problems will be solved, including the fact that the factory wiring is crap by now

I will be rewiring either way, I have already purchased a brand new genuine loom

Just need to work out what ecu I should go for as per my first post

It depends on what you are using the car for, what mods you have and your budget.

Waste of time if you only bought a new engine harness as it's usually the power harness on the left hand side that is the worst

The car is already modified enough for what I am wanting to achieve out of it.

347awkw

Car will see more track days than street driving, it is not a daily.

Reason why i purchased a whole new engine harness is because it has been hacked into in a lot of places, have been told the easiest and cleanest way is to replace with new. Which is what I am doing

Both ECU's will do the job but I imagine the SMC would have a few more input/ouput options for things you might want to add later

Is there any other option of how to install the SMC? I prefer not to hack into the new loom if I dont have too . . .

I have a few spare female GTR ecu connectors you could have $20 + postage or pickup just wire it into the autronic and plug it in.... its how i do all my wire ins..... allows the cars loom to remain intact so it can be returned to std in minutes.

Dont want this to look like im hocking parts, just a suggestion.

Keep the SMC its a great ecu, different but great.

Ye as Dan said, depends on what you want ultimately.

If you want to log a few extra things. Keep the Autronic.

If you don't then the PFC will also be fine.

Most circuit GTR's in Vic that are still street driven on occasion all use a PFC.

When you go out & out racecar, extra logging can indeed be handy etc.

You'll need to decide/talk to your tuner & what not.

A little off topic Trent. I have the same ECU and I am interested in one of these ECU connectors for my car (33 GTR). Is there any chance I could grab one off you. I tried to send you a PM but It didnt have the little tab for to do so. pinch.gif

yeah i looked yesterday and have one left. drop me an email and i will pack it up.

yeah the autronic is a great ECU and the CDI is great too. there's also nothing wrong with a power FC. both of them if tuned well will run the car beautifully. you could swap to the power FC and sell your current autronic set-up and probably not lose any money in the process. power FC is great on a street car, they run very nicely.

really up to you. a patch look for the autronic is a fine idea though too.

    • Yeah well per the video it took 15s for the stock unit to start up....even if I give it a few seconds discount for starting that is at least 12 sec before you get a reverse camera if you are trying to leave a park.  The android unit is way faster, but 2016 for the stock unit is a long time ago in consumer electronics
    • Yea that’s why I said ima test them with multimeter and see the reads.
    • Only at idle. Isn’t a problem when rev it seems.
    • @Haggerty This seems silly to ask, but are you confident in your ability to tune the Haltech?  
    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
