The Sniff Stick is used to clamp onto your exhaust to measure the AFR using a wideband sensor. Ideal for those who can't weld the socket into the exhaust or when the wideband sensor us used for multiple vehicles.
This product is an accessory for use with the LambdaKing MkII.
Prolonged exposure to temperatures exceeding 350C should be avoided.
Not recommended for exhaust diameters over 90mm.
The LambdaKing MkII and wideband sensor are sold separately.
Customer Reviews
Easy to use, good detailed instructions. Excellent product support.
The design off this stick is flawed, and needs to be rectified. Sensor is on the incorrect side in relation to the fixing lug, putting the sensor and wire in the heat zone. I had to fix mine, which cost me 75 dollars, and I want it reimbursed.
Andrew,
Thank you for your feedback. As discussed on the phone we will take your notes into account in the next revision of the design.
Our website shows the dimensions and installation photo of the device. We publish this information so that customers can confirm compatibility with their vehicle before purchasing; In this case just the photo of the Sniffstick would have made it obvious that there would be an issue with a large diameter exhausts.
We recognize that sometimes customers overlook the product specs and run into problems. We therefore accept (in most cases), change-outs, upgrades and returns. A return and refund was offered in this case too, but was declined because you opted to modify the device yourself.
Asking us to reimburse your labor on a public forum, after having declined the refund, is neither appropriate nor realistic.
All the best,
Ray
The sniff stick has made it easier to move between cars and is a solid piece of kit.
The unit was helpful in resolving a rough running issue down low. Response to changes in mixture was fast. Luckily I attached the sniff tube with stainless steel zippy ties before a full power check in the air. After climbing a few hundred feet about 4 inches of the tube vaporised. It kept working ok but will only flight test with exhaust mounted sensor in future.
**** product reads constant lean called and got no help
Hello Dean,
Thank you for your feedback.
As we discussed on the phone, a lean reading can be the result of a number of reasons such as free air entering the exhaust stream trough a bad gasket or a hole in the exhaust. This has happened unbeknownst to the user on some previous occasions. Mishandling of the sensor like dropping it, or blasting it with oil from the exhaust can also lead to anomalous readings.
For these reasons, it is not possible for us to remotely determine the cause of the unexpected reading, all we can say for sure is that your device like all others, left our shop fully tested and in working order, and is covered under our warranty terms.
We have provided telephone support to assist with finding the cause of the problem, and offered to bench test the device, which you declined due to 'not having time'. We also offered to declare a dead-on-arrival case for the sensor, in consideration of the limited time use, had it been found faulty and without any obvious signs of damage.
It is regrettable that you have opted to instead dispose of the device whilst still under warranty, as we would likely had resolved any issue by now and at no cost to you.
It is of course your prerogative to dispose of your device as you wish, but we respectfully disagree with your assertion that no help was offered.
All the best,
Ray
