Subaru aftermarket ecu (sorry devesvws)

[a914622]

I have used the Electromotive system on a nasty 302 chevy 8v. Its good stuff.
Iv also head good thinks from the Maga squirt crowd but have not used it.

Iv received a few PM's about using the Stinger system in the past few weeks. I just wanted to update this post. I have heard thur the PMs Outfront motors doesn't run a knock sensor, and claims its not needed. I have found that not the case with the heavier vanagon.

All things considered, I personally would go for it! Half the fun of all this debauchery is the fun of tweaking and tuning and getting things how YOU want them. I had fun putting that motor in the vgon and the other half of the fun was the harness and actually tuning everything to perform how I wanted it to. The stock ECU would be easier and blah blah blah but you can tne this bitch to how you are driving it! Really now, how cool is that?!?

Before Electromotive was in the Engine Management system, they were an automotive ignition company. The benefit of using the Electromotive Engine management system is that it is built on top of their robust ignition system. On our race cars, we can not hear detonation or pinging. I would think on a street vehicle regardless of weight you should be able to tune the timing on the timing table if it is pinging or the mixture. It allows for setting timing and mixture not only based on rpm, but engine load. I don't want to knock knock sensors, but they were installed on vehicles to compensate for poor grades of fuel. If you are running on the knock sensor, something is out of adjustment. I race against others that use the Megasquirt and the Motec. Motec engineers are a bunch of snobs. Megasquirt is more priced to the do it yourselfer. I think the ECU's come in kits. Not sure how their tech support is. Electromotive Tech support has been top notch. If your reseller can't help you, they usually can. I'd like to learn a little more about the megasquirt system. I think one might be able to be adapted to work with the Vanagon engine harness, by putting the parts in the stock VW ECU housing. Just not sure there would be enough demand to justify the effort. mark

I would have to agree with you about the Motec. After spending that kind of coin I expected to get online support. I was tuning a 2.2 porsche 6 twin plug and youd have thought I was asking them for the launch codes for nuks..
I think the Electromotive has the ability to use the knock sensor??
I know there is a guy locally that sets up kits from junkyard parts for the mega-squirt. The majority of the stuff comes off the ford Zetec focus. But again I'm not familiar with it.


I think in the vanagon a knock sensor should be used. And again not to hijack the thread but the PM i got stated a 2.5 suby was destroyed by pinging/knocking wile running the Stinger 4 !! I am not running it any more.

The guys at Metric motors did me up a stock 02 impreza harness. Great guys!!!

Yes the TEC from electromotive systems can use a knock sensor as an additional input. The knock sensor would also need some tuning. I still believe that most street high compression engines can be tuned so that the Knock sensor is a safety input rather than an actual online input. Lower compression engines would be even less likely to detonate. In order for the knock sensor to work, it needs to recognize a knock. That means the engine has already passed the safety zone. Better in my opinion to tune so that you don't depend on the knock sensor. We race 15:1 4 cylinder engines without knock sensors. We do run 115 octaine leaded fuel to fight detonation. In racing the horsepower and torque are best just before detonation and before too lean a mixture. It is a fine line to sneek up on.

Without pointing any fingers, I am now running a Subaru ECU in my 87 GL Syncro. No Knock Sensor/ NO Bueno

I have a stinger 4424 on my ej20 turbo in my 1974 Bay westie and I just experiencedsymptoms of a cracked piston.
Is it stingers fault? My tuner? Dreaded rand on ringland failure?
