Disconnecting the MAP?
I am pretty sure I know this but I have forgotten. I forget alot these days!
Can anyone tell me what the effect of disconnecting the MAP sesnor would be on the engines running? We are talking a stock engine here. Overfuel, limp mode, or would the engine still run fine relying on the TPS. ![[Image: AEU86 AE86 - Disconnecting the MAP?]](http://i57.photobucket.com/albums/g239/N2AE86/memberbanner1jpg.jpg "AEU86 AE86 - Disconnecting the MAP?") http://www.eight-six.co.uk - read the blog!

both spak and fuel maps are primarly based on the map sensor.
So you car won't run very well ... The TPS is only used when your accelerator position is changing |

Yes... what ^^^^ he said. If you disconnect the hose, the MAP sensor
is reading atmospheric pressure which = WOT. Therefore the engine will be running rich/very rich at anything less than WOT. Cheers... jondee86 |

From what I read it causes more problems than it provides benefits. Because of the bigger throttles, the BT seems to run a different fuel map to the ST, and this causes all sorts of running rich headaches !!! Cheers... jondee86 |

Why did you disconnect it? Its the main sensor for the ecu in non-AFM cars.
A wheel to steer the front of the car A pedal to steer the rear |
