Nope, you need the settings in the .bin changed so everything works correctly. It'll have to go in at the shop unless you have the ability to make the change and burn a new chip.

You can split the map wires to hook the 2.5 bar map sensor, but keep connected the oem map, then when you are on the shop, connect the 2.5 and disconnect the oem.

bingo, mount everything, run the wires, and just unplug the stock map and plug the new one in.

Yup, I have my 3 bar spliced in. If you do this just be sure not to have more than one map sensor plugged in at the same time.

Good idea! Wouldn't the ecu wig out because it is receiving two signals?

Ninja edit: Oh wait, I think I know what you mean. Just don't hook up a vacuum hose right?

No, don't have more than one map sensor physically plugged in at one time. I spliced mine in and tried to start the car with both the 3 bar and stock sensor plugged into the harness and the car wouldn't start / ran like ass when it did start.

Ooooh. Maybe I should just solder it in at the shop. Lol I'm not really pickin' up what your puttin' down. I didn't want to be that awkward guy trying to do a shitty solder on his map sensor with pink heat shrink lol.

Ok, you have two options when it comes to your map sensor:

1. Snip the oem plug off and solder in the plug for the 2.5 bar

or

2. Splice into the OEM harness so that you are able to run either then stock or 3 bar map sensor.

What I was saying is that if you do splice into the OEM harness for the 2.5 bar just be sure not to have both map sensors hooked up at one time. For example, I spliced the plug for my 3 bar into the OEM harness. Right now, on my car, the stock map sensor is hooked up and the plug for the the bar is sitting there waiting. Once I do plug the actual three bar sensor back into its plug (which again is already soldered into the OEM harness) then I need to unplug the OEM map sensor.

Your car is obd1 correct? If so, you have a TB mounted map sensor correct? If so, same principal applies but you will have to swap the map sensor on the TB itself.

Make sense?

Ahhh I see what you're saying. I got confused because the Motorola's don't have plugs, just 4 wires coming out of the sensor.

Where did you get it from? We use a plug on our motorola 2.5 bar sensors that you can pull off, just be sure to put it back on the same way ;)

and the wires are soldered on or do they lead into a little black plug?
They look soldered on. There is black heat shrink around where the wires connect to the sensor and I don't want to pull hard enough to break it or something.
