zaheer0027 Posted October 30, 2016 Share Posted October 30, 2016 Hello I'm a bit confused on maf and map sensors. I have a j spec 94 na sz.i believe it is a maf sensor. Would I be correct? Can anyone show me a picture of this sensor? Can someone also show me a picture of an oem map sensor that came on a tt or na engine? Because I'm going na-t I bought an aem 3.5 bar map sensor as well as an ait sensor but if I already have a oem map sensor then there is no need for me to install it. Any help appreciated. Thanks Quote Link to comment Share on other sites More sharing options...
Mk4Gaz Posted October 30, 2016 Share Posted October 30, 2016 Maf sensor is on the intake, just after the air filter. Map sensor will be on the inlet manifold, a small electrical sensor with a vacuum hose Quote Link to comment Share on other sites More sharing options...
Wez Posted October 30, 2016 Share Posted October 30, 2016 What ECU / piggyback are you planning on using, those sensors cannot be used with the stock unit. Quote Link to comment Share on other sites More sharing options...

I'll take some pictures just to make sure 100% as this is all new to me and as I am doing all the na-t work myself I just want to make sure.

I have an aem v2 stand alone but I have it for sale at the moment as I can't use it due to tuner not being familiar with the product. I will be using a haltech stand alone.

zaheer0027 Posted October 31, 2016 Author Share Posted October 31, 2016 Ok so this is the bit from my na engine. I'm assuming this is the maf sensor. This is a pic from my aristo v300 vertex tt.I'm assuming this is the map sensor. It is located on the intake after the throttle body. Thanks again Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted October 31, 2016 Share Posted October 31, 2016 The first pic is the air intake temp sensor, the flowmeter is in the intake pipe as stated. The second pic is a MAP sensor, correct. Quote Link to comment Share on other sites More sharing options...
zaheer0027 Posted November 9, 2016 Author Share Posted November 9, 2016 Thanks for the above. So today I had a look at the engine bay of my na.i think this is the sensor. From looking on the net though it seems my car is map and not maf? Can someone please confirm. First picture is the sensor in the intake with the vacuum line that goes to the plug Second picture is the plug with the part number on it and it says SENSOR ASSY VACUUM Quote Link to comment Share on other sites More sharing options...

Mike2JZ Posted November 10, 2016 Share Posted November 10, 2016 All jap spec non turbo's use a MAP based system, only the American non turbo supra's have a MAF system. For your haltech you will need to use the supplied 3.5bar map sensor. You will also need to use an air intake temp sensor. Haltech have their own which may be worth buying if the haltech software cannot detect the stock air intake sensor. Quote Link to comment Share on other sites More sharing options...
