Sensor is likely std Denso. If you can find the pull up value, I can do a curve and find the temps that correspond with your voltages, very easily. May already have it in stock.

I think that's the bugger. Meant to be used on most other Nissan's of the era also.

Bosch? On a Nissan? Really?

Someone's Nissan workshop manual:

viewtopic.php?f=24&t=100

Photos of the sensors on most Nissans match my Mazda one in the above thread.

My values match that workshop screeny, too.

The above Bosch has a similar curve, though.

Fred.

I am very very close to having this PCB ready to be sent for manufacture!

I am aiming to complete the remainder of the work required today and let Fred, and whomever else is interested, have a day or so to review it before the order is placed.

I need this relatively quickly, so unless there are physical connections that are incorrect, shit with reverse polarity, etc I won't be caring about any comments relating to aesthetics initially.

I will post up when I have pushed the updated PDF and associated Altium files to git.

Stay tuned!

:-)

Sounds good. Let's go over it in real time via skype as soon as you're ready. Let me know when.

I would volunter myself as one alpha tester.
I don't have knowledge to actually review hardware efficiently ( I plan to acquire it as times go by, always help bringing females onto my orbital field.), as long as you have a bill of materials and a pcb design you feel confortable with, I can build a board for myself, and start testing and aquiring data on a harsh environment. I plan to do it on a jaguar first, and keep both ecus runnable.

A week later, no sign of it! Not that I mind, mind you, just pointing out that every time you do that it hurts your credibility to deliver. If you want my review, you have 3 days, max, to get it to me, probably less.

Excuse double posting the above :-)
