Bosch integrated pressure/temp sensors
#41
Yuba, I can't speak to your problem, perhaps by now you've figured it out and want to share what the root of issue was?
msmola2002, I'm wondering how the sensor has been doing with your sealing method. I'm eyeing a $45 cheapo version of this sensor on Aliexpress. I'm hoping that if the sensor leaks, it would tell me so with a low pressure warning
I have seen the similar Lowdoller-branded sensor posted recently with a 1/8" NPT thread, if adapting m10 doesn't work well maybe I'll have to go that route.

The next K24 I put together is getting a Syltech sensor for a few reasons:
1. Don't need to deal with the trapez plug
2. The Bosch seems to end up leaking eventually, sometimes explosively
3. 1/8" NPT instead of this weird M10 that requires an adapter, the adapter moves the temp portion out of the fluid stream making it somewhat less accurate

Yeah, so my issue was that KPower grounded the sensor to regular ground instead of sensor ground in their early K24 BRZ harnesses.

Also, for what it is worth, I am running the Lowdoller pressure/temp sensors for my fuel temp / fuel pressure and coolant temp / coolant pressure. They work fine but I had to make my own resistance table for Haltech, I wish they had a lower temp range for better resolution.
Lowdoller 899404 Pressure & Temperature Combo 150 PSI / 500*F

No leaks here from where I screwed it in, but seeing a lot of failures in the Haltech group on FB. The thought of a knockoff of a part that may also be somewhat questionable, I would not do it.
Unfortunately my miata project will be winding down in the next year or two, to eventual sale or partout, so I'm not investing time on continued improvements.
The consensus in those Haltech circles is also the Syltech is the way to go. Can also be purchased from platinum racing products in oz, from just up the road from my home town. Wait til black friday and get some free shipping on that **** - I did that already for sensors I planned to use for coolant and fuel pressure. https://www.platinumracingproducts.c...ctions/syltech Bear in mind that is in Aussie pesos, so figure about 2/3 the price. If you wish to buy locally, there are some drift boiz down in Florida who sell Syltech already.
