3500 LX9 in a 1999 Grand Am 3400

Hmm, I guess depending on how they changed the tone ring on the cam it might be larger in diameter or something and need a shorter cam sensor... Odd... Did any of the wire colors match up?

[Preacherman]

I did this all three weeks ago and when it didn't start I walked away from it for a while but if I remember right only one color matched, red I think. Then on one the one was blue while the other green, then one black vs brown I think. But anyway it was not a situtation where I could have used the 3.4 one. Thanks I'll let you kniw when I get the adapter on and running if I have more issues.

I think the 3500 one is longer because it doesn't have the wiring coming out of it, but rather a plug for the wiring harness. I suspect that the part that actually goes into the block is the same length. The crank sensor, on the other hand, the 3400 sensor IS about 3/4" longer than the 3500.

I have a 3400 cam sensor, i'll put it in my spare 3500 block and see if it fits tonight...

Exactly how it worked for me. I didn't take pictures but it was identical from the O-ring down. Getting it out of the block was a chore but it fit without any issue.

Only way I've removed mine is yanking on the wires. Other ways will break the tab. I've re-used my original cam sensor every time I've had the LIM, which was 3 or 4 times lol

the 3400 sensor fits the 3500 just fine. they are the same length.

idk if u did it already but u also need the crank position sensor from the 3400 behind the dampaner and the 3400 dampaner

i'd move it back to 0 and work on the tune from there.. you are losing a ton of power having it in that position.

have not started tuning it yet, but I tryed it at 0 to day and the car is a dog now! lol going to try about 1/2 of what it was before and see how it works. It dose feel abit better in the low end but its not pulling as hard above 3500.


Preacherman any updates?

are you sure it's at 0? there is a line on the sensor block that should line up with the 0 on the mount.. With mine the 2 small allen bolts line up perfect with it at 0.


can you take a pic of it?
