The 56 ohm Zalman pc fan resistor has worked. Runs even smoother for some reason....

Ok, going for a longshot. Any ECU guru's here? How about a Zalman fan resistor swap (increase resistance) over the old one.I am completely stuck until Tuesday! Anyone have an ECU apart with the numbers on the burnt resistor in photo (R1)

Yep. There is also an odor coming off the heatsinkers (heatstinkers ) .I'll just get a new board. 13 years and a precise clock ought to be a freaky nuclear byproduct by now running that long.. . Cant just dip that in the degreaser and call it good.

I would guess the differences to be turbo, non. I did find a part that fried (at least one) I found the clock was ridgidly placed in and surrounded. I wish pc's did that..Here is a pic of inside the 13 year old super computer. http://www.ultimatesubaru.org/photos/showphoto.php?photo=11205&cat=500

I hope you have the channels run for your speakers and not using subaru speaker wire setup... The shared ground is bad news.

I found 3 numbers for an spfi ECU. aa396, 397,398 Can anybody tell me the subtle differences? I have a chance to get a different one than original number.

I am certain it was problem, I am currently no ride.. it has been awhile since that has happened.Only event number 2 since 1997 (with just 2 old subes) that has left me stranded, and this second time is my stupid fault... Loyale 2.7 turbo, i used your weber pics on my site, thanks!

ECU really stinks. I Left it outside. Having built my personal computers and killed them for years now, I would think a dead board would smell familiar. This one has an odor all its own . I didn't hurt the wires, it was my simple mistake.I took cover off, power on, no heat on regulators/resistors nothing.Gotta remember this sensitive subject next time. found replacement at salvage cheap, same number (396).Thanks for help.

Have power turns over, noticed the CEL light no go and no start. Checked ecu light, nada. I was messing with wires near MAF, and heard something click on SPFI unit. I went to start car and no go, just turns over, all fuses good and fusible links. Somethin is stinkin from ECU. I think I killed it. Anyone have one? This is what mine has for numbers (2wd 5spd, spfi):

Is there afuse for ECU? I turned key on and no start. to see there is no blinking light on ECU. Is it dead?

I bet this would even help a quicklaunch off idle:lol:

I saw something like this awhile back posted. This one has everything in it tho. If you think an ea82 needs a giant turbo... Just an electric fan blown into airbox changes how it runs.There is not much happening in an engine that gets 40mpg on an intake smaller round than my... :-\ Interesting gadget to kick in at 1500 rpm or so ... (why wait till full throttle?). I still believe it works like they say, except pushing my own luck switching it on at lower rpms ...

I bet it was timing not a valve float.If I'm not mistaken there is 135lbs on valve springs on a short tough cam and lash adjustered all very close for tight function. The weakest link is two timing belts two lengths, on two tensions, drivers side especially having a harder turn. Keep the top end cool for the bad flowing heads-- it just takes a few milliseconds longer to achieve the same flow than larger heads. I have gone to 7000 and knew I could keep going until it flew apart internally (not even the heads). Of course the weight of 4wd is also another killer no matter what is done. I have done this on a 2wd. Surprised the hell out of me when I put into reality that it could be done smoothly.Torque demand in other words would be the other big factor. I am confident due to an old worn v8 I had that hit 8000 in a 3000 lb car on 115 lb springs and a fat cam just "thrown" in to see what would happen. The oil pump will fail due to heat, not rpm first. Keeping the top end very cool seems to fix that too for quite a high rpm range....

The air filter in my loyale is quite old and paper like. The K&N filter with gunk all over it is ridiculous. Twice I have seen it on an EA82, and around here, it decides to squeeze something replusive off and the engine, MAF don't like it at all...One chemical attracts another, to shed yet another. I stay neutral, dry , clean simple inert filter and call that good. I am assuming it is yet another product where everything is dry and dusty to be deemed a successful place worthy of it.I am well over 30mpg local on normal cheap filter(it is quite old too)...and never falling for the goopy mystery fly catcher chemical again.

My car did this too, it was a combination of many things that turned into an extreme problem, I ended up making stuff http://93loyale.50megs.com/ntakt.html Browse around, my similar probs are cured. Right away, be sure the EGR isn't stuck open,#4 cylinder sometimes never comes back....after affecting the car with said symptoms.

I stuck a portable screwdriver bit under mine to extend it about an inch. It doesn't exactly make a short throw, but it fits my odd arm length or size.I have to crouch over to shift and finally sit back once in top gears for awhile...(no need for a pic on this one):-\

Those bearings can be tricky. My 2wd stayed silent all the way to a sudden 4 wheel steering on a corner doing 55. The pattern of failure was perfect for steering the rear wheels to the right. I did get to wobble and wiggle it home without further problems....Luckily nothing destroyed and new bearings went right back in on same hubs. Quiet as a mouse now on the Federal mogul replacement (non-OEM)

Doesn't even need to be said out loud. I recently got climbed up on by a tractor trailer on I-95. My finally functioning speedo said 85 mph. The truck must have been doing 100 on his dim round headlights climbing right up on me. I sped up to get away and see the blues flashing in the rear view mirror. I slowed way down to 70 and the cop car flew by both of us, all the while the truck was right on my ***. I immediately sped up again to 85 and finally lost him in the hills.... My only regret with my little soob is situations like that. The 40mpg is an ovverruling maturity regardless of maniac truckers and whatever else wants to be intimidating.

My car has "beat me up" written all over it so to speak. I don't understand it. My wagon didn't ask for this. The poor droopy pants sedan must be lacking an aggressive appearance... Yet a car like my old 74 chevelle sedan (which really weighed 3250 lbs -- unlike a suby-- what a beast!) was moving things out of the way long before I got there. I never told anyone it started off with a 100hp 250c.i. 6 cyl with a top speed slower than a 400k mile ea82 wagon. There was so much room under the hood, I could stand inside the engine compartment, next to the engine while my tools sat on the inner fender well as I worked on it, I could lay down on the hood with my head on the windshield, and my feet had a foot to go before the end of it (I am 3 inches shy of 6 ft tall). But anyway, that car is gone like thier production.I have had road rage incidents already due to "this gang up on me" mentality I don't ask for. I even got pulled over for speeding, and knew damn well I wasn't. What does my sagging sedan need to stop it: A fake plastic blower glued to the hood maybe a hood scoop... four 1 million blinking candlewatt lights on the roof rack Oh, I know, some texan bull horns on the grill like a pimpin rancher in his big 'ol caddy... perhaps a lift kit and mud tires for my 2wd.. a train horn... a fake roof camper like a vanagon... some cop lights... fender wideners, while keeping my little stock wheels... a 3 foot protruding front bumper with an oversized license plate... hmmmm... there has got to be somethin to make this little car look bigger.:-\

That was my deepest thought about the whole idea.the rest is managable dynamically. I have read up to the dyno pic, if they could only get the proper weight of the car in the algorithm... is a legacy 3250 lbs? I had a wagon claiming similar weight, I dont believe it. I have always assumed the numbers for hp to be off because of it. Excellent work.Alot of custom fine tuning without the deep math to work with by engineers. The dyno pic for torque, is well rounded.I could analogize the engine glowi ng at its peak. I would guess at this point cramming anymore in isn't likel? forgive the typos, new iexplore is killing my keyboard at ng's only.

If a single long cammed v8 can on bending pushrods and valve spring pressure less than an ea82... I am willing to bet it can, no float, no nothin...no sweat:burnout:

better than a turbo however. I found something.... http://www.magnusonproducts.com/mp45.htm The roots seem to be main stream. This charger even looks like it would fit... What a day dream I could be having. 135+hp quietly , no lag, internal bypass direct link for a broad range of rpms-- up to the normal. I wonder if 200ft lbs of torque is out of the question being the response is so tight.. I'm satisfied, I may take a crazy dive into something like it on an old EA82 sometime.I still may try a smog pump, where there was no air, now there is some....If opening an air box and cooling top end down etc gives noticable improvement, any pump would work....

from about how stuff works dot com They have my thought exactly about engines being forced to wait for a beneficial return on a turbo. A flawless full stroke is needed (4 banger) to achieve higher rpms. At bottom of stroke another cylinder is finally compressed to fire (the biggest self strain on any engine besides friction), the just fired stroke is at its weakest point of its own fire to get the other one ready. A supercharger responds at slow rpm which would be especially beneficial to a four cylinder. I hope a genious company with thier supercharger simplified proves it out loud.(I bet it is going to be a subaru) http://www.automotive-technology.com/projects/subaru%5FSTX/ Now back to a turbo creating backpressure at slow rpms on a four cylinder that really needs every bit it can get to wind up... I don't like it. It is unrealistic, and is a factor in thier lag. Just two more cylinders and a turbo is phenomanol becuse there is still fire left in one bang while another cylinder starts thiers. Four cylinders need something special. A turbo just doesn't make sense for the full range of rpms and every day stop and go driving, while a supercharger could, even in the cold (even better i would guess- less oxygen needs more air for the engine to make up for it, especially torquing take offs etc)

The superchargers I found spun at 56-65000 rpms,thats (sixty five thousand -not hundred) not as high as a turbo, but it still does the purpose(I was finding 8psi- just add that to physical compression higher than a lower 20lb turbo engine...)and centrifugal pump with gear reduction, must equal the exhaust pressure driving same turbo turbine, if customed to the engine to get same output. Turbos get away with more thier cheaply to be more universal with blowoff valves, etc.A supercharger would absolutely have to be precise from the get go as it functions instantly, exactly to the engine it is bolted up to. I saw this on a 5.0 mustang (not my fav car, but very common for mods) A bolted on SC drove oem to 600hp and the guy threw a stock conrod thru the block laying on the ground. Only for the reason, that it was exactly built for the 5.0 and its oem intake, compression, etc.maximizing it. It can be done, but it is no doubt the cost. I like to see the suby's do have some now. The Brat looking car has 230 hp and high torque with it. Nice. What can i do with an ea82 to have belt driven air charge (just a little one- not thinkin dragster.... ) the old smog pumps seem like a candidate from 70's american v8's.

True, it must be the cost. Linear type flow to parallel instantaneously to throttle is as close to zero lag as a charger (turbo or super) can get. Also , I read about the fantasy of EGR and Subaru enjoying cannibilizing thier own engines with it. The turbo is good for thier pursuit.As far as higher rpms being better charge... of course. Just like a turbo. I searched around to see successes of it, I really like the thought of it. Subaru has several models out with them now with realistic numbers. I bet the 'ol EA82 will still be runnin until Subaru makes something I really want if it takes half a century...
