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.

    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
