why did you put ecu / alternator
you aren't making sense
an ecu couldn't fry an alternator or vice versa. pls explain.

Lol@ you cant fry an ECU
I mean I believe it is an electrical problem.
I was driving in the left lane, all of a sudden my sound system dies. Ok. Monsoons are temperamental. Airbag light comes on. Now I'm curious. All of a sudden my car kicks into limp mode, no turbo, and I'm losing RPMs... but the tach is stuck at 3K and my speedometer at 80, all my gauges are frozen.
throw on my blinkers, move into the breakdown lane (at this point I'm going 40, gauges still stuck)
So I check the engine bay. All good. Make sure the battery terminals are secure. Yep. My car still has battery power but the starter isn't going, let alone catching
Who knows. Could be a fuel problem, it was running really rich at start up. This is the first time its hit limp mode since before I cleaned my IAC

Alternator sense circuit can short to ground causing overcharging and blow the ecu.

What are you loling at? You understand the basic concept of how an alternator works, obviously. Your alternator could not directly "fry" your ECU. That's why I was confused with the slash.
Anyway, it likely sounds as if the alt is your problem. ECU only goes into limp if it's an issue related to something else. A fried ECU would kill your car immediately, not go into limp mode. The alt no longer charging your battery or letting the starter turn over is a pretty likely diagnosis.

Does it crank? If so does it sound like the engine is free spinning? Does it have about 105k on the odo? Could it be the timing belt

That's a wiring problem though, not the result of the alternator burning out. Overvolt shouldn't happen anyway with fuses in place but god only knows with an early 90s GM..

The slash was supposed to mean either one of those haha.
Idk why it died so suddenly... no grinding noises or symptoms of any kind.. Fucking VW.

Overcharging condition is totally possibly to fuck up an ecm

If its the timing belt I'm going to superpunt my dad in the nads. I TOLD that nicca we should change it.
Engine barely, barely cranked. I'm at 135K, haven't actively checked it since 121K

Dodge Stealths (last car) get leaky caps and short everything, I don't think VWs have that problem in general (Stealth/ 3KGT specific) but ECUs DO have thr potential to fail
