PMP light on stim flashing?
 
after finding out i didn't need to install D8 on the ms1 v3 board i've removed it.

Now on the stim the PMP light flashes on and off, in TS in the bottom right hand corner it says flashes fuel pump on/off.

Anyone know what this could be?

Thanks in advance.

the pmp is the fuel pump light on the STIM, so if MT is somehow cycling it, then it's going to show on the stim.

D8 is just a diode for the on-board idle circuit, you need to remove it if running you the PWM idle valve mod, because the polarity in backwards. It should of had no effect on the fuel pump circuit unless you fubard something. The fuel pump circuit is (R16, R40, Q19, Q2, and D4)

Thats great thanks, i've flashed again with the hires code and it seems to have sorted itself.

Just need a hi res base map now, any ideas bud?
