FLDSM88 Posted May 26, 2009 Report Share Posted May 26, 2009 I have a 88 starion where is the MAP sensor located? Link to comment Share on other sites More sharing options...
Shelby Posted May 26, 2009 Report Share Posted May 26, 2009 best way to find it is to read the first chaptor on fuel system how it works in the fuel system section in the fsm and guys don't tell him any diff Link to comment Share on other sites More sharing options...
FLDSM88 Posted May 27, 2009 Author Report Share Posted May 27, 2009 I read through the fuel system section in the service book, and the only thing I could find is the MPS. It didn't mention anything about the MAP sensor?? Link to comment Share on other sites More sharing options...

mikec Posted May 27, 2009 Report Share Posted May 27, 2009 No "Manifold Absolute Pressure" sensor on stock StarQuests. Those sensors are used on "speed density" based fuel injection systems. StarQuests are "mass air" based systems; they measure the actual airflow going into the engine and compute fuel from that - just like a carb does. The MAS (Mass Air Sensor, aka AFS or AirFlow Sensor) is the plastic contraption hanging inside the air filter from the air filter canister lid. 86-earlier StarQuests have a boost pressure sensor on the firewall; but not a manifold vacuum sensor. 87-later cars don't even have that pressure sensor. mike c.

Shelby Posted May 27, 2009 Report Share Posted May 27, 2009 we or i wasn't trying to be an a** but ,was trying to get you to read for your self,,there is no map just as Mike C said now care to tell us why you thought it did have one Link to comment Share on other sites More sharing options...
patra_is_here Posted May 27, 2009 Report Share Posted May 27, 2009 dude, my 86 has a damn MAP sensor. the MAP sensor on the 86's DOES read both vacuum and boost signals, AND those readings will alter the injector pulse width's accordingly.

Indiana Posted May 27, 2009 Report Share Posted May 27, 2009 Yes pre87 cars have a pressure sensor but he said he had an 88. I'd guess he was looking at other turbo cars and is wanting to maybe change that sensor out for one that has a wider range. Sorry, there isn't one.

FLDSM88 Posted May 27, 2009 Author Report Share Posted May 27, 2009 Thank you for the information. I read on another forum about the pre 87s having the MAP. THe reason I ask is that I am going to run the EDIS 4 setup, and it is either read off of the TPS or a MAP sensor. I ordered the TPS board since I couldn't find anything about the MAP sensor, but I hear your really want to run turbo cars off the MAP sensor. I am going to try the TPS and see how it goes.

You could add one down the road if the tps based timing does not work out. I have one of these. I am only currently using it for data logging. http://www.diyautotune.com/catalog/map-bar...nsor-p-161.html You could probably find map sensor in a junk yard that would work if you want to take the time to figure out the wiring. Not sure the j/k ones have enough range though. Try turbododge. The turbo fours ran a map i think. Link to comment Share on other sites More sharing options...
FLDSM88 Posted May 27, 2009 Author Report Share Posted May 27, 2009 Yeah just looking at that sensor I would imigane that you would have to run tubing to the intake manifold and the Y out to the control module on the megajolt. The wiring shouldn't be to bad it looks like a positive, negative and a ground and the megajolt instructions show how to handle that. i think I am just going to run with the TPS and see how that goes.
