I am pretty sure you still have your timing descriptions backwards.

Stevo

He does.

I think what they did was tune the car based on knock retard timing events and wideband. They failed to do the most important step, which is to check the spark plugs. However, what he's saying is the knock sensors were pulling too much timing. And they tried to tune it to where they would be less active, thus indicating that there was less indication of detonation. It's just a really backwards way to say not enough fuel or timing retard was the cause of the problem. He's looking at as the knock sensors where pulling a lot of timing (his word: too much) and that was indicating moderate to severe detonation. They tried to add fuel to compensate, but it didn't pan out.

He's got the right idea, but his is the dyslexic version.

You are right, what I should have said is the more knock the more it ruduces timing. My bad for reversing that. Car only ever sees 16* total timing so reducing timing to reduce the KR function would make the car a dog and fall flat on its face. Just adding a little more fuel up top helps reduce the detonation so the knock sensors dont have to come into play.

[stevo]

No, I ment too much. There is detonation and the car commands how much retard it needs. The more it has to reduce the more knock. The more knock the more the chances are of chipping a piston. Adding fuel up top helps to reduce the knock which will reduce the knock sensors activity. Reduced knock also means reduced chance of cipping a piston.

I wasnt aware that the intake was that kind of issue. Thought it just spewed some coolant outside the motor and since I didnt see any coolant leaks I went with it.

Truth


Because from doing research I have found some people having troubles with knock retard with these constant 104*+ days and too much knock retard can chip pistons before the computer can react. We were simply adding more fuel to eliminate that threat.
Was not a performance tune, no rev limits raised, no shift points changed, no timing adjustment. Only fuel enrichment to help the motor.

Was just bad timing.... no pun intended.

So exactly why did you buy one?

GM 3.8 > Ford 3.8.

Truth

Why were you doing a tune on a daily driver when you're flat broke? The last thing in the world you need to do is fuck up your only car trying to hot rod it.


I have no idea what spark advance and a/f ratio look like on my Dodge and I don't care either...

Have you tried bolt on motors in south dallas? They tend to have a supply of motors there. I haven't bought one yet, but my neighbor has and its still running..Going on 2 years without a problem.

Might as well shoot your horse too. Just sayin.....

[mustangguy289]

Yup, GMs fault. Was just checking the oil and can see the slightest hint it got water in it. Lower intake gasket is stock or the stock design. What ya wanna bet I pull the blower and see a bad lower gasket?

Fact of the matter is GM builds many chitty cars. Yes the LS engines are nice and the new Vetts are bad arse but GM plastics always sucked, cant make a working clutch for Vetts, Dexcool was a joke, Northstar motors are the biggest piles, 3.1 and 2.8 were some of the worst motors ever made.

Is the 3.8 SC engine a good one? Well for the most part. Address the intake gaskets and the crappy oil pump and they will handle a lot of abuse. But as I learned, for such a cheap part you wouldnt even think about in any other car its enough to kill the motor on these cars.

[LaserSVT]

So the car ran perfectly for 12 years but minutes after being tuned, blew up? Yeah, definitely GM's fault.

Damn bro. Hope life turns around for you. I wish it was about a year later. My plan would be to be able to pick up a property like yours for an investment property. Good luck with everything.

[LaserSVT]

Understood, man wish it wasn't so far away, I would love a lot smaller house payment and the land.
But we're trying to get my dad to move here and this may be good for him. Can you pm me pics and specifics please? Also internet provider, city water or well, etc.

Internet is sat only. Water is city.
