Autronic Engine Management System

[olsonjus]

I just typed up a huge reply and the computer crashed. I'll keep it simple this time.

I was planning on running Autronic sm2 on my audi, but I've been a bit turned off by there very expensive wideband o2. You can't use the autotune feature without their wideband, so they have the market cornered.

I have since been looking around and found that AEM is a good option for us 5 cylinder guys. I was talking to a AEM engineering the other day on their forum and he recommended the mitsu evo 8 ecu. It has 5 coil drivers and 10 injector drivers which is perfect for us 5 cylinder guys. Plus, they have an option of a internal wideband analyzer. It comes with the sensor also, so you have no problems with compatability. All this for just $1700 USD. You can get the non wide band ecu for ~$1350.

If you want more info, visit the tech forum over at

The evo 8 with intergrated wideband is part number 30-1313U

A schematic can be found at:

AEM is grate but who will provide You basic start maps to run the engine. When You plug the standalone there is no program tu start Your car ... Y ou wold have to write it by Your self. There are start programs for Supras ect. but not for Audi.

But mabye I was miss informed :confused:

But You don't kneed the wideband o2 all the time ... just for tune ... the o2 could be obtainted at Your local Autronic diler for tuning time or at You good tuner.

Mmmm true, the wideband is expensive, but from what little I have read about it, that autotune feature looks really good.

Mark Shead @ madevelopments says there is support for our cars, as apparently there are a couple of Audi Autronic specialists. Will speak to him today and get some more detail. I suppose the Autotune feature will greatlly reduce the set up time, most EMS extra cost comes from dyno set up time. 3B owners will benefit more in terms of cost due to ignition type. I wonder how versatile the Autotune feature is on a heavily modified (Mark H / Doug) spec engine?

IMO it wold help a lot

my friend on stock supra gained 60HP more than on a chip just for pluging standalone and doing the mods in it

that is why i will go for 100% for stand alone ... now i just use unichip

AEM has autotune also. With the built in wide band, you really dont need to go to the dyno. Just monitor knock and egts, and you can tune it yourself. The dyno is really only needed if your worried about HP numbers. Track times are what count to me, so the chassis dyno isn't really necassary.

Do you really think that all you have to do with autronic is hook up all the wire and it will run? This isn't the case. You have to write your own basemap with autronic also. If you can't do this, you shouldn't be playing with standalone. I believe the more knowledge you have about your car the better. I'm wiring in the AEM on my car just for this reason. If you want something done right do it yourself.

I don't have any knowledge of this controller - what advantages does it have over the proper remapping of the original ECU that myself and Mark have?

And since ours is remapped by a very experienced guy(Mihnea), who is mapping these controllers properly?

Lol, when is anything ever that easy .

I think Doug is right. The re - mapped Motronic ECU does produce good results when done properly. Most aftermarket EMS are probably more valuable to those building a car from scratch, where buying a genuine ECU / loom will be quite expensive (most s/h specialists will only sell these parts complete with engine). From what I have gathered, these aftermarket systems will NOT 'talk' to the original instrument clusters in Audi / VW 1999>. I spoke to Keith @ Dialynx and he said the dash HAS TO GO. Motec dash is £3,500! :eek2: :eek2: As far as S2's go, the dash is 100% compatible with any aftermarket system.

and do You have a base map for 3b engine also ?

- A standalone system will enable You to map the program in anyway that You like vs. there are some limits in ECU.
- standalone will gather sensor info faster and adjust the engine work faster ... becouse it is faster than standard ecu. This wont mater when going for 400HP but going for 600HP will.
- standalone will enable you to set start procedure
- standalone has Anti-Lag
- standalone has fast shifting
- standalone has Data Logging
- with stanalone you don't care about maf
- it has a internal map sensor 4.4 bar absolute

and so on

there are many advanteges

for large HP numbers the only solution is standalone

Sounds good Albert, but do you know of any way you can run these standalone systems in lets say, an RS4 without changing the dash insert for Motec or similar? Spoke to Keith @ Dialynx, the S4 - engined TT they built running Motec would not 'talk' to standard S4 dash insert, they ended up using a Motech unit. Is there a way around this? I would be interested in buying this system, but want to keep the stock RS4 dash insert.

ok You want be able to keep oil or miles per galon info ... but who needs them, stand alone is made to keep the car runing and You for Your self have to make shoure that the oil is there but having seperate oil gauge
