Hi folks,
I'm looking at getting the 2Y1 DIY kit, but I'm a little lost on the choice between the 3 sensors, does anyone know which is best?
Also I gather nistune's datalogging will work with this kit?
Cheers

Hi Adam,
Generally most people go for the 7057 as its the cheapest and most readily avaliable. Here is the description from the Techedge site:
One major difference between these sensors is the "head" design that is fairly open in the 6066 but is more restricted in the 7057 & 7200 sensors. An open head results in faster Lambda sensing, but also make the internal pump cell more sensitive to exhaust gas temperature variations, with the possibility of over-heating or under-cooling if the sensor is located closer of further from the optimal position. In general, we recommend the lower cost 7057 & 7200 over the 6066.
Photo showing this:
I personally would probably grab a 7057, the open head 6066 may be better for single cylinder bike engines and cammed V8's if it is faster sensing for faster response, but that could also be a double edged sword if it makes the lambda reading even more jumpy and harder to read/interpret on a cammed motor than it usually is. Not really sure on that one!

I'm 99% sure these use a normal Techedge v2 datastream for logging, which Nistune supports. Matt would be better to answer that than me though.

not sure on this unit. unless anything has drastically change in protocol (which shouldnt) then i dont see any issues. techedge have used the same protocol for years since upgrading from their older one

I guess we will find out, mine arrived today, I'll solder it up tonight.

Hi
Any news on this? I'm also quite interested in one of those, but would like to also connect type k thermocouples to this unit and log in Nistune.
Would this be possible?
Thanks
Christian

assuming the wideband works okay we should be able to translate the thermocouple inputs

Yup no issues with Nistune talking to the unit, (Tech2.0) I have a 3Bar MAP sensor connected via one of the AUX ports and it reads it perfectly, along with the AFR.
I haven't gotten myself any thermocouple units to try yet, but don't see that being an issue at all.
Cheers
