Looking for Graph of Linear MkIV Stock MAP Sensor (Turbo Pressure Sensor)
I am seeking anyone who knows of a link or has a charted graph of the linear factory 0-5v MkIV MAP sensor. I know this has been charted many times for the MR2s and Celica All Trac, but was wondering if any of you know where I may find a similar source for the Supra.
Here is what I am looking for:
ST205 (MAP) vs ST185 (AFM w/ Turbo Pressure Sensor)
If anyone has a chart like this of the MkIV Supra MAP sensor 89421-12111 or similar, your assitance will be greatly appreciated!

that looks like a power FC graph.... im not sure but for some reason i think the supra and MR2 uses the same MAP sensor. but im only about 10% sure about this
Unfortunately, no MR2 or Celica in the US were equipped with a MAP sensor. Toyta ceased its US Celica Turbo All Trac production in 1993, just before the introduction of the Gen III 3SGTE.
In Japan, 1994 was a big year for MR2s and Celicas as they went to the MAP equipped Gen III 3SGTE engine. Although the US export of the MR2 did not cease until 1995, they contunued to use the AFM-style Gen II 3SGTE similar to that of the US/JDM 1993 engine through 1995.
Here is where I'm going with my request. I'm working with a Gen III 3SGTE Celica and I am needing to know the difference between its MAP and the MkIV Surpa. Gen III 3SGTE MR2s had this same MAP sensor like the Supra, but they were given different part numbers for each vehicle making it difficult to cross reference the interchangability. The only chart I have is for the engine I am working with, the ST205 Gen III 3SGTE.
I know that the Gen III MR2 MAP sensor will interchange with the ST205 Celica, but neither one is available in the states. With an 8-10 week wait and a hell of a dent-in-the-wallet to ship from Japan, I'm looking into other options. With the Supra being available in the states, it would be much easier for me to cross-reference and source this sensor over the others; that being if it will work.
sorry pal, you are wrong. every toyota equipped with a turbo came with a MAP sensor, and every CELICA except the 7th gen has a MAP sensor because they run on speed density
You are being argumentative because I am sure you know what I mean. There are differences between these sensors such as voltage, linear/non-linear, etc. The US MR2 and 2JZGTE Supras do NOT use the same MAP sensor as the Gen II 3sgte uses an AFM engine and a non-linear Turbo Pressure Sensor.
If you want to get specific there is a part number for the MAP sensor graph I seek above.
I beg, I'm not after a tech argument , I need a graph. I can open another thread if we all want to talk about the difference between differnt MAP sensors and the difference between AFM, MAP and Speed Density equipped systems. This thread is only about my search for a graph.
Anyone want to help something I NEED to know, like a chart by chance?
