Shaun Wilmer Posted January 5, 2014 Report Share Posted January 5, 2014 I've just started wiring up a G4 Storm to a mazda rx7 FD3S. Reading through all the documentation the 2 main temp inputs are for the water and air temp, which I sorted with the sensors in the manual. I'd like to have the fuel temp as a correction too and was looking at using the AN-volt 4 input, but the manual says the difference between the temp and the an-volt is the temperature channels have an internal pull-up resister. Can somebody recommend the sensor and pull-up resister I can use to get this to work correctly. I'm looking at just using a wideband to free up the AN-volt 4 for use (manual shows wide and narrow band on ANvolt 3 & 4) Shaun Quote Link to comment Share on other sites More sharing options...
Kelly Gordon Posted January 6, 2014 Report Share Posted January 6, 2014 The temp inputs are thermistor inputs AN-volts are 0-5V inputs. You can use either input depending on what type of sensor you use. Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 6, 2014 Report Share Posted January 6, 2014 Any normal NTC temp sensor will do such as those you would use for coolant or oil temp. If wired to an AN input use a 1kohm pullup as per page 39/40 of the manual. Quote Link to comment Share on other sites More sharing options...
Shaun Wilmer Posted January 6, 2014 Author Report Share Posted January 6, 2014 Thanks, didn't find the right page in the manual. Will sort an NTC style sensor out for it. Shaun Quote Link to comment Share on other sites More sharing options...

Shaun Wilmer Posted January 11, 2014 Author Report Share Posted January 11, 2014 Parts have turned up, I'm in the process of pulling the wiring through to the bulkhead and come back to the manual on pg39/40. The sensor I have is the bosch 0280130026 and it has 2 pins, is the diagram to one of the pins and the other to the sensor ground ?

Simon Posted January 12, 2014 Report Share Posted January 12, 2014 Yep one to sensor ground the other to the ECU input. Quote Link to comment Share on other sites More sharing options...
