Megajolt won't advance timing and map sensor isn't working
Turbo Mini Forums

Hi, I've just installed a megajolt to my mini turbo and it seem to have some issues ! The timing is stuck and won't auto adjust and the map sensor isn't working. Can anyone help?Dean

Sounds like connection issues with mjlj
The edis module will start and run the car in limp mode on its own with static timing

How do you know the map sensor is not working?

Yes i moved to the darkside

If I rev the car or suck on the vac pipe the gauge doesn't move

I didn't shield the wires from the edis unit to the MJ may be that's why!?

sounds like the jolts not getting power, even with no rpm signal you should see the MAP gauge move in the software.

if you were seing the gauges move, bit no advance then it would be the signal from the jolt to the edis, or the edis itself.

Green light is on and revs are showing on the laptop! I did purchase a tps MJ and fitted a map sensor with resistors.I now know why it's took me two years to fit it!

Are you sure the software can see the MJ?

In the 13's at last!.. Just

Yes the laptop is talking 100%

In that case im almost certain you have to flash the mjlj to tell it its now got map sensors instead of tps

good call

I'm on it! thanks for your help boz

New firmware programme won't load! This is getting a pain in the arse

If it's been converted from TPS to MAP it needs resetting as it wont recognise the MAP signal

Masturbation is not a crime its a hobby

Tried two computers and firmware software won't load I'm beginning to wish I left it alone

have you checked the MJ board in case any solder has become brittle or anythings come loose?

Yeah I checked it and resoldered just in case
