I haven't been able to find solid info on this - perhaps it's moot, but I'm looking at replacement reference sensors (i.e. crank position sensors, TDC sensor, whatever some of you guys call them) and there are a lot of options, with prices from $45-$150+ for each sensor, Porsche or BMW.

A lot of them are brands I've never heard of, like Facet, and some are brands I do know but have heard lukewarm things about, such as FAE. I have Bosch sensors in the car now and they're acting up after about a year (although they were slightly used when I got them) so I'm not buying into the "Bosch is best" thing unless proven otherwise.

Anyone have experience with some of these aftermarket suppliers, or any vendors to avoid?

Anyone? Bueller?

Are you sure they are gapped correctly? The originals usually last forever, except for the connectors, or if manhandled getting them out. Not like there are any moving parts to wear out, just coils of wire.

Facet stuff usually works well.

Thanks for the info guys.

The gapping looks ok on them, but I'll be looking for a surefire way to set it correctly. I'm thinking of using washers with a known thickness.

The connectors on them are fine, might as well be new. I'll snag the Facet ones if issues remain, thanks again.

Ferris here. Sorry Mr. Hacker, I was just feeling so sick I could hardly bring my fingers to type on the keyboard. But you don't worry about me, I'll be fine, I'm sure. The sensors on Camerons dad's Ferrari seem to be holding up fine. But he never drives the damn thing, he just sits around and polishs it. Were's the fun in that? Try that washer thing. I would agree they should be pretty robust, except for the connectors, which were apparantly designed to crumble when they got to age 30. Pretty much sums up life, doesn't it? Ferris

To adjust the gap, I use a small circular piece of cardboard that compressed down to the 0.8 mm gap. I glue that to the speed sensor and make the adjustment. The great thing abou the cardboard is that it wears away without requiring disturbing the adjustment.

I lost it! Thanks.

Agh, I think I'm barking up the wrong tree anyway. The car is randomly dying every once in a while. It doesn't matter what the engine temp is like nor the RPMs. Sometimes it's 10 seconds after starting the car, sometime 10 mins. Always starts right back up and runs fine. I'm beginning to think DME solder joint.

Don't bother trying to find the bad joint. Just hunker down with your soldering iron and spend an hour resoldering everything. If you aren't accustomed to soldering a lot, use the largest tip you have that won't get in the way and keep a decent coating of solder on the tip. You want to spend as little time as possible on each pin. If they aren't melting completely within 2 seconds use a bigger tip, higher output iron, or more solder.

I have always used the Bosch sensors and have not had an issue with them. The original sensors were made by Bosch and they do seem to last a long time. I bought new Bosch sensors from Pelican over the summer for about $80 per sensor.

PelicanParts.com

The Bosch units are dependable and should last for quite a long time. We also offer the FAE units as a less expensive alternative. The best part is, you may read actual user reviews for both sensors on our catalog page.

Let me know if you have any questions!

Thank you

My car currently won't start and has no tach bounce when I try to start it. Everyone is saying it's my S/R sensors so I just ordered new FEA ones from ECSTuning.com

I'll let you know how they are when they come in next week!

Dan Martinic

Did you have any issues with the FAE sensors?

Not to sound like a snob or anything, but when it comes to OE Bosch equipment, I don't screw around with the Chinese imitations. Do it once, do it right, forget about it for years.

The lone exception is the DME Relay... I embraced the f9tech solid-state units.
