I was just about to lay down the cash for a Apexi Power FC for my R32 GTR,when a very knowledgable and trusted source mentions Autronic as an option.I realise that both Autronic systems aren't merely "plug in & play" like the P. FC.,but I'm interested in having the features of the full management system.I'm used to seeing the Apexi unit in almost everything that comes from Japan,so this Autronic thing is a new thing to me.I considered MoTec for a brief second,until the Bank Manager drew the crosshairs on me...and Microtech wont get a look in(been down that road with a friend before).The car is,effectively,standard right now,but will be the recipient for 2530's,pistons,rods,cams,clutch,fuel system etc etc in the not-to-distant future,hence the debate between the known quantity(Power FC)and the Aussie contender(Autronic,obviously...).I'm torn between the two-any info' on what you lot may've been through with either system would be appreciated!Cheers,J.

Looking at your mods list (noting the great choice of 2530's), the Power FC would be my preference. For less than half what the Autronic would cost, wired and tuned.

Have a look at any of the PFC versus other ECU's threads, the Wolf is probably the best comparison. All the advantages of the PFC are listed.

Are there differences in the power FC's across the RB25 production years?

I have a 3.0 running an RB25DE head, and have been reading these sort of topics with interest.

I have been wanting to wire in an autronic or haltech as I think it would be enjoyable/a good experience especially with an engine conversion however I am a bit worried lately about getting an engineers certificate and a powerfc in a nissan box is looking more and more attractive.

whats wrong with wasted spark anyway? ignition problems? get the autronic cdi, that has so much power you can melt the end of the spark plugs off if you wanted to. If your going to try blow out that spark **** knows how much power your going to be making.

autronic can controle the standard idel controle valve, air con idel up, colsed loop functions so i have no idea where it is so called not as good. If autronic is so bad then same goes for motec as they are nearly identical as they come fromt he same makers after they broke up, and how many motecs do u see in japanese cars, alot if they are so bad.

SR910, And how much extra is the CDI? Why bother buying a more expensive unit like Autronic if you then also have to buy an extra CDI unit?

Of the two choices given I'd go PFC, but if you can find a good tuner then the Wolf is also a good choice.

Autronic CDI only has two caps so they are close to usless.Two capasitors 6 coils you work it out.

WE have a GTR making 683rwhp on a Wolf with stock coils, see this car in the current Zoom as it has just run 10.7 at 139.96mph.Waste spark is a bad thing and we even got our money back from autronic for a SMD and CDI that could not handle the ign this GTR now has a Plugin wolf and problems are solved first try after 3 years pain with the old set up.

Autronic and Motec are now far removed from each other as the split was many years ago.

I own a old autronic SMC and i'm wrapped with it but thats just me as i like to play with things.

It handles the Idle valve and ignition very well but i dont have stock coils anymore i have a 3xtwin coil packs & modules from bosch or something.

Also i have to raise another point about autronic ecu's are you need to replace the trigger disk in the CAS.

Now for you i would say get something plugin unless you really want to dish out the extra to get a SM2 with all the nice little extra's that the smc doesn't have.

Also the smc is really overpriced last time I checked compared to most powerFC/plugins prices i've seen & the sm2 is lots more.

PS on a side note they are fun to tune if you have all the gear (Autronic WB02) and hooked up correctly.

i have an SMC installed in my supercharged mitsubishi pajero, its an evo lancer plug and play with an extra ignition driver wired into the board. it works awesome, plugged straight into my original loom and i have the advantage of a nice big laptop screen to look at for tuning.... and how good is that auto tune feature, autronic is certainly not behind the eight ball when it comes to ecu's

I HAVE to agree with Steve-SST, an ECU is a package, you just can't simply pick out 2 features and say it is better because of those. :headspin:

Let me choose one for comparison, a PFC with Commander is going to be 1/4 the cost of a Autronic and a lap top. If I have a "free" lap top, then I can add a Datalogit to the PFC, still less than 1/2 the cost.

How much extra did the auto tune really cost? Software, wiring, F&W lambda, tuning time etc etc. You get nothing for nothing.

I have used Autronics in a number of cars, BMW Supertourer, Commondoor (all of Larry's customer cars came with Autronics) etc. They are a great ECU for particular purposes, not EVERY purpose.

Horses for courses :thumbsup:

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
