I'm looking at getting rid of my HKS f Con V pro and getting an Autronic SMC, what are peoples experiences with these on a RB25? I have looked at the power fc route, but I believe i will max out the afm with the mods I'm looking at doing. Where is a reptuable tuner for Autroics in Queensland?

cheers

heard nothing but good stuff about the Autronic ... many argue that they are on a par with Motec for smaller outlays.

try the guys over at calaisturbo, theres many threads on them there... a popular choice for the hi powered vls

IMHO autronic are second only to Motec, but it's close. The guy that owns/runs autronic (Richard Aubert was his name I think) was originally one of the founders of Motec. The quality is definately there and their ECU's are also a bit cheaper than Motec. The main issues with Autronic in the past have been:

- after sales support was not great

- some have reported problems with connections to some types of engine sensors (eg CAS - not RB tho)

I suspect with greater web based support in recent times these sorts of problem have been largely overcome.

I would say they are better then motec but thats just me. The guy that designed it, software and hardware(Richard Orbit) was the brains behind motec before he left. The autronic uses a thermodynamic model to determine fuel delivery. Thats why you must enter engine capacity, compression ratio, amount of cylinders etc etc. Its very smart and lots less mapping than motec as the maths is done for you.

I have seen a Power FC and AFM equiped GTR run 8's at 165 mph and make 1100 bhp. Is your target higher/faster than that? If not, the Power Fc is your best choice.

hmm I've seen afm max out on RB25 with a 3540 regularly. GTR have 2 afm too, I've only got one - being a rb25. Whats the autotune feature like on autronics? is it worth it? I just may have to move the car or drive it at some stage before i get a chance to get it tuned, as I've got to drive a fair way to get it tuned living in hicksville and all.

I have an RB31DET with 420+rwkw and a Power FC with one Q45 AFM, no problems. PFC = out of the box, install in 5 minutes and drive to the dyno.

Autotune on Autronics is OK, but you need a fast and wide lambda sensor and the tune needs to be close'ish before it will auto tune. Simplistically you can't just sick it in with no maps and expect auto tune to do the rest. If you have a fast and wide lambda sensor, display and some experience you could get it perfect using auto tune and then trimming yourself. You don't need a dyno.

Forgetting about mapping for a minute, there is a considerable amount of setting up to be done with the Autronic before the engine will even start. You really need someone with experience to do it, it's not a job for a first timer that's for sure.

The PFC is the best answer.

;) cheers :)

yeah the Z32 air flow meter in a mates car maxes out in no time .... not sure how you managed it Sydneykid - good stuff if you have. You usually end up with a small flat spot in the dyno graph when it maxes out. I have quite a few return to idle problems with my cams and have to set the idle much higher than i would like, let alone with an afm in place, would only open new problems, I think I'll stick with a map sensor.

So who in queensland is a goot tuner of autronics? I don't really want to have to buy one and drive 20 hours to NSW or VIC to get the thing tuned.

Check here as a starting point:

These are Autronic dealers but can probably point you in the right direction.

Like SK my vote goes to the Apexi PFC . Aftermarket engine management is reasonably complex to install - read expensive and time consuming . Even after that without a generic base programme to start with it wont even run .

The Apexi PFC goes plug and run with all the std sensors and AFM . I used an Autronic SMC for about 3-4 years and every time I plugged the lap top in I wished it could have load sensed off a hot wire mass air flow metre . Its one thing to tune a Map or manifold pressure sensed system but difficult to get the correction maps for air and water spot on . To a large degree the hot wire sensor takes the hard work out of this because its load signal reflects mass flow ie CFM AND air temperature so the air density can be known as well . I've heard people say that they'd prefer the old gate type afm to map because it tells the computer how much air the engines ingesting not just manifold pressure . The map sensor signal tells the computer nothing about air volume or density so crude means of correction are needed to get the programming right .

For burial rights - should you wish to remove the Autronic when the car is sold its a fair bit of work to refit the original computer/sensors/AFM/loom etc . If the constabulary were to find out (some of them are petrol heads and know what to look for) its much easier to refit the std computer/AFM/injectors .

Apexi PFC will maintain its resale value better than a second hand Autronic .

Cheers A .

If you have to stick to an Autronic ECU. Stick your head in the manual and study the hell out of it, learn to tune it yourself.

If you are going to go to the trouble of buying and setting up one of these ECU's, make the most out of it by knowing how it works to get the best benifit.

Most tuners that i've researched don't or are unwilling to cram every ounce of horsepower out of your engine for safetys sake. Especially if it's a street car.

I intend to tune my engine myself, just rent out the dyno and crank it up using all of the Autronic options. I'm not too concerned about cracking an engine to learn what they will handle.

If you can get 420rwkw with Pfc, thats heaps for the steet if you ask me. For a dedicated race care (drag race), i think the Autronic is ideal.

Cheers

I am going to give my vote to the Autronic. If it is wired up correctly it will have at least one air temp sensor.

QLD tuners recommended:

● Hi Talk Performance. Ashley is the head tuner here. Ash is formally from APC. Phone number: 07 55 006512

● Pitt’s. Matt Spry runs the show there. He has an excellent reputation. Phone number: 0411340033.

Both of these guys tune Power FC’s as well so they can, and will give you an honest opinion on both these ECU’s from a tuner's point of view.

I know both of these guys so you can drop my name if you like.

:P Ricky from Fantasy Performance.

Crock....of......you-know-what.

How many cars running even 1 second SLOWER than that WORKSHOP car and faster than 165mph want NO DATA LOGGING?

Professional race teams - not backyarders or street-car racers run 8's and they don't do it with Power FC's unless they MAKE power fc's or sell them.

Sorry mate but "..the Power FC is your best choice." is a horribly general statement and very irresponsible advice.

I would also love to see the dyno graph for the RB31DET.

Adrian

P.S. I run a Power FC on my street car and think it is one of the best choices for that application. I sure as shit wont be using one on any out-and-out race car that may or may not be in the future.

PFC's are ideal for street cars, but an aftermarket ecu is the best choice for a more race-orientated car. The only question is which ecu? I would go for the ecu that your tuner is more than comfortable tuning. This piece of advice is constant amongst all the ecu threads that I have seen.

Geeez! What is up with all you people always bad mouthing the Motec and Autronic systems? You people carry on like the Power FC unit was sent down to earth from God himself.

If you want to know why the Motec and Autronic systems are far superior to the PFC send WetGTR a PM he will be able to clear it all up for the doubters.

Do you guys realize how easy it is to actually tune an Autronic system? Adam (WetGTR) showed me himself how easy it was to tune. Do you people realize how well this system will work for even a street car?

The PFC unit is an economical upgrade and a good one but if you have the money the Motec and Autronic systems are light years ahead.

Ookami, if you really want to know what an Autronic is like ask people that use it. My suggestion is PM WetGTR.

I wouldnt go preaching about someones car unless unless you helped build it, or are the owner.

Adam (WetGTR) has had his share of problems as everyone else has at varying stages.

Its not my place to say these things of course. And nor is it Adam's if he see's this and chooses not to comment. Its his R&D with RPM and there is a lot of hours as with every major HP car.

But i can say that its up and running now, all issues sorted, making great power. All a owner wants at the end of the day

No full wire-in ECU comes without niggles and other things that can take time to nut down fully. Hence the PFC is a good option for simple and medium level applications.

High end applications is where arguments like this come about without people being fully informed.

Go with what works, and what you need to achieve that goal

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
