first trials no map signal !

Post by ivanhoew »

well i have now got my turbo mini running with the megajolt, and its definately a lot smoother at all rpm , the only prob seems to be a total lack of a vacuum signal on the software readout ,
.im using als excellent windows tuner ,and all the live stuff works fine ,except theres no map bar graph movement , its stuck on 100kp iv blown down the pipe into the mjlt i got direct from brent ,and theres no leak on pressure or vacuum ,and my guage reads vacuum and boost and thats where the takeoff is for the mjlt . any suggestions ? oh iv configured the software to the box for map .
thanks
robert.

when you blow into the tube going to the MJLJ, does the software runtime update?

Ok-

Just to eliminate the possibility of a hardware/assembly error (gasp) unscrew the lid from the case from the molex connector side, slide the board out and verify:

1- proper connection of the hose from the barb to the MAP sensor
2- Installation and proper soldering of components in the MAP sensor region of the MJLJ board (components in the white outline). Check the back side of the board.

Let me know what you find.
