Nerd Media Posted September 26, 2018 Report Share Posted September 26, 2018 Hi all, I have a 1999 Nissan Silvia S15 (SR20det) and I will be installing a LinkECU G4+ plugin ECU in a couple of months. I'd like to run a IAT Sensor however im unsure which one would appropriate based on the options available on the LinkEcu website. http://dealers.linkecu.com/IAT1-8_2 Or... http://dealers.linkecu.com/IATB_2 Any ideas? As for wiring, could I use the MAF sensor wiring? alternatively what would be the best way to wire it all up to the ecu? I do have the XL loom (As im also running: oil temp, oil pressure fuel pressure). Dane Quote Link to comment Share on other sites More sharing options...
Simon Posted September 26, 2018 Report Share Posted September 26, 2018 The IATB is my pick as far as response goes but it is the harder one to mount. Wiring wise one side of sensor to sensor ground and the other needs to head to a AN temp input. Quote Link to comment Share on other sites More sharing options...

Thanks for the info, im assuming the sensor has to be parallel to to the flow of air so it can be tricky to line it up right? Quote Link to comment Share on other sites More sharing options...

I dont think the orientation is too critical. I think probably more what Simon was talking about when he said "harder to mount" is the threaded sensors just need a tapped hole. Whereas the plastic Bosch sensor needs a smooth reamed hole (for o-ring), as well as a flat machined mounting boss and a drilled/tapped hole. We do sell weld on bosses for mounting this sensor for those that dont have machining facilities: http://dealers.linkecu.com/IATBMA_2 Quote Link to comment Share on other sites More sharing options...

What's the difference between the two sensors LinkECU sells? Quote Link to comment Share on other sites More sharing options...
Simon Posted September 27, 2018 Report Share Posted September 27, 2018 The Bosch one is slightly faster reacting and the cals are slightly different (Just a different sensor selection in the ecu) Quote Link to comment Share on other sites More sharing options...

Simon Posted September 27, 2018 Report Share Posted September 27, 2018 Yep identical in as much as the ground and signal come and go from same points. (plugs are different) Quote Link to comment Share on other sites More sharing options...

Simon Posted September 28, 2018 Report Share Posted September 28, 2018 Just the sensor and matching plug you will need wire it back to the ECU Quote Link to comment Share on other sites More sharing options...

Any chance you could point me in the direction to what the wiring is called? Cheers Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 28, 2018 Report Share Posted September 28, 2018 You said at the beginning you already had an XS loom, that has two temp inputs available so you can connect your air temp to one of the temp wires and your oil temp to the other.

Oh, I wasnt aware that was how it functioned, its still sitting in its packaging haha! How many pressure sensor inputs does that XS loom have?

Adamw Posted September 29, 2018 Report Share Posted September 29, 2018 The S15 ecu has two expansion ports. Expansion connector 1 has the 2 temp inputs and 2 volt inputs, your pressure sensors connect to volt inputs. If you need more than that there are another 4 volt inputs on expansion connector 2.

So to wire an IAT sensor on an s15, you take 1 wire from the sensor ground and one wire to the An Temp 3 input? Is there no way that the factory MAF wiring can be utilised?

Richard Hill Posted July 27, 2019 Report Share Posted July 27, 2019 The s15 plugin does have the facility to wire a temp. Sensor through the AFM. See below for extract from manual HTH, Richard. Quote Link to comment Share on other sites More sharing options...
