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 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.

      It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪

      And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil

      Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.
