I appreciate the help, but I'm not an electrical engineer so I have no idea what I'm doing. All I know is I have a sync-loss problem and nothing more.

Should I call DIY and ask about this or am I barred from support due to not using MSpnp2? I'm about to get some help from someone on here with the soldering and if things go wrong and this is like a bad joke or something, I'm in trouble.

1) Remove the two resistors mentioned (R2 and R3)
2) Desolder white wire from pin 1 and solder it on white wire on pin 3
3) Desolder pink wire from pin 2 and solder it on pink wire on pin 4
4) Enjoy your car

Clearly, you are a straight-up-player.

This thread needs less boring wiring questions and more skanky [car] pictures.

*My computer wanted to correct skanky to swanky. Uh, no.

I have two photos, one is supposedly pre-modification and the other post-modification

Pre:


Post:


As you can see, R2 and R3 are already gone from the pre-mod, and Q2 and Q3 are gone from post-mod.

Also, I see no wires in the pre-mod picture that need to be desoldered, as mentioned in steps 2 and 3.

And frankly, I don't know where you are getting the pin number references.

Looks like the connection from one of the pins on the DB9 connector that goes to R2 is being taken to Q2, but since I'm guessing this is at least a double layer PCB, I can't follow all the traces.

Any further clarification would be appreciated, as I don't want Hustleberry crying if something adverse happens

Like he would have to just unplug the VVTTuner for a bit until it is fixed?

I gave hustler some contact info with who he should talk to at DIY.

I won't cry, but if we do mess it up I'll give you a great deal on a VVT head.

Well, as I mentioned earlier, anything I do I can easily undo, but I'd rather make sure I do the right thing the first time.

I'm getting conflicting information that doesn't correspond with pictures and without a proper VVTuner PCB schematic, I'm a little in the dark.

A board layout picture like this would be extremely helpful

I don't suppose anyone has one handy

I emailed DIY but I feel Reverant has shown me the way.

This is something I really need to learn, I'm paralyzed without the basic skill.

Ya, and I can do this for you quickly since you need the car, then teach you so you can do it on your own in the future

No worries Trey

Do exactly as I said. Exactly.

If R2 and R3 are already removed, obviously omit that step.

If you look closely at the DB15 connector, the pins are labelled.

Looking at the connector on the VVTuner, pin #1 is on the top left. It has a white wire on it. Remove it from #1 and solder it on pin #3, which is also a white wire.

Do the same with the pink wire on pin #2. Remove it and solder it on #4.

Simple as that.

Ignore any other information you have seen, heard.

Ahhh, you're talking about the DB connector pins. Beautiful

That's really helpful
