Hi all newbie here
I'm in the process of building a loom for my s80 pro and wondering if I need to change my stock sensors for it to read them. Basically I have single pin temperature sensors on my engine and the manual shows the temp sensors as being earthed back to the ecu.
The other thing I was wondering is it necessary to run an air temp sensor and a lambda?
I have a 3 bar map sensor, cam, crank, idle, tps, turbo control, water, oil and oil pressure.
Cheers in advance
What sensors do I need?

Re: What is sensors do I need?
Std 1 pin senders are primarily resistance based from gauge to earth whereas the DTA (and more ECU's) feed the sensors a voltage and expect to get a voltage back modified by the sensor resistance, so better to use correct sensors (they'll also be calibrated to the ecu or vice versa)
You are running a turbo? If so, i'd consider both AT and lambda (wideband) to be essential. Oil temp and pressure aren't necessary for good ecu control.

Re: What is sensors do I need?
what engine?
if its been on an ecu before then its likely to have a two pin sensor that you can use already, or fit a known type in its place

Cheers for the replys I will be changing over to the correct style sensors. Engine was an mfi setup before so very basic.

What engine, what use, what do you think you need etc etc ?
And no, a single wire temp sensor will not be suitable for supplying the ecu with information.
As for necessary....depends really. Are you tuning, is someone else tuning etc ?
