Saga of a standalone ECU.

[scuzzy]

So I priced the Autronic from some dealers in the vicinity (read, country).


The going rate for the plug-in unit is $1800. Far out of my price range. That puts it at about $2100 for the ECU, a WB02, and EGT setup.


So I'm looking at the Haltech E6K, an ecu that the guys over at nasioc.com use alot.

The problem I have with it is that it's wire-in, and I'm not aware if anyone has built a harness to adapt it to our cars or not. That would make it more appealing.

Additionally, I can't find any base maps to start with.

Anyone have any clues, know anyone who's used this or still does on our type of cars?

The SDS ( Simple Digital Systems) is not too expensive, straightforward
in tuning and can be ordered with a loom that fits the older Leg. turbos, or whatever.

The guys who build them run a 2.2 Impressa on the street as well as on track days. They also convert 2.2 engines for small air planes.

In Vancouver,the guys that do the work on my car built and maintain a couple of Nissan
GT3s that are consistent winners in SCCA--like lowering the lap record for
the class at Laguna. They are now going from carbs to FI, using the SDS.

Its reliable and can be simply tuned at the track.

im interesting in how well the SDS would work.. any oh the electrical oriented guys on have any opinions....

[scuzzy]

Unfortunately I'm not interested in the SDS due to it's lack of configurability. Everything can only be done through the two-line LED display and I'm just looking for more power.

Not to be picky but if I'm going to spend a good hunk of change, I don't want to make big compromises.

I'm pretty sure Morgie is running the SDS. He has the EJ22T short block (forged piston with slight overbore) and EJ20G heads. He was running high 13's @ like 10 psi w/ the 16G!

Maybe you have already found something to tune with but if not you could look at using the A'pexi Power FC. It is a stand alone ECU that, if you get the right model, will plug right into your Legacy Turbo wiring harness.

I'm about to try and use a Power FC in my car. I've been using a '94 Legacy turbo ECU and had hopes of flashing the chip but that has fallen through.

The Power FC is almost plug and play for the Legacy, almost because to use it you will have to switch from a coil pack to coil on plug. Other than that from what I can see it is good to go and if you pick up FC-Datalogit you will have really good software to tune the ECU with.


noah

[scuzzy]

I'm in the mood for updating my old topics.

I'm using the EJ22 (Non turbo) harness. I won't be switching, so it's a little more work for me regardless.

I don't care if an ECU is plug and play compatable or not, I need one that supports all of my stock sensors, can read my crank and cam signals without modification, and can use the wasted spark setup (which I don't care to change unless I can get 10HP from COP Vs WS)

So it's just finding one that meets those standards, building a plug-in harness so that you can plug the ECU into the stock connectors is easy.

Have you looked at the Link? I'm trying to decide between the Haltech E8 and the Link Plus G2. If you don't need the adjustable resolution, the standard link shouldbe a good option at about $900.

[suberboy]

The Power FC would support all of your sensors but will not run waste spark. I tried to run waste spark with it and it started and ran but only on two cylinders. I ended up paying $100 for 4 WRX coils and $35 for a WRX engine harness which I stripped down to just the ignition specfic wires and connecotors and it has been working perfectly.

Sounds cool!

Yeah, too bad APEXi closed their US operations.

NEXT.

Haltech makes a plug in harness for Subaru WRX MY 93-97 for the E6X-

If the Autronic plug in for that car goes into a legacy SS then this should plug in as well. I just haven't had time to test it as I'm wiring another standalone in our shop car.

Autronic essentially plugs in, but there's a few things that have to be changed around first, couple of pins and whatnot, that's about it.

I'm guessing the WRX didn't have the backwards TPS so those wires would have to be flip flopped. Other than that I'm not sure what the differences are.

the early WRX's used coil on plug, not wasted spark, so a couple of pins have to be moved to take care of that.

cam and crank sensors are pinned different from the NA/Turbo and have to be changed for those of us who are N/A

I can't remember all what else needed to be done, it wasn't extensive, but I reviewed autronics software and I can't recall if it's the price, lack of maps, or software, that turned me off of them.
