megasquirt woes !

Ms2 extra and im frazzled on the rest i have tried uploading an msq and help file to the ms forum 3 days now and still waiting for a message to say the posts ok for going live !!

Been conversing with phil and ive sent an msq to him this evening the annoying thing is the tunerstudio tooth logger doesnt register teeth or trigger ? Ive tested the sensor the wiring for continuity adjusted the pots ???

Can a ford crank sensor magnet degrade ?? Im thinking as the sensor is second hand may be my issue ?? As ive tried everything else so far !!

it may sound like a daft question but what is your trigger wheel made of. i only ask because i went to help someone that has a similar issue and found the problem immediately. the trigger wheel was made out of ali.

who built the ecu? have you checked the ms board to make sure the correct input path path bridges are in place

Ive moved from the std vauxhall wheel as my original sensor was fubar ! The new sensor (oem. ) is no good as the ecu is set for vr not hall effect plus i couldnt find any documentation on the sensor wiring for oem.

Switched to trigger wheels universal trigger wheel ( bought the wideband from them too )and its steel ;-) and sourced x 2 ford sensors from a scrap yard. Both tested ok with the multimeter changing resistance upon waving metal.

I did try retro fitting a ford vr sensor down the old vaux sensor to see if that would work with the std wheel 60-2 and std 114 deg setting
. No joy !

The ecu was built by phil at extra efi and his aftersales is bob on but many thinkers find ye problem ! Ive got to do a data log of the ford sensor in both polaritys tomorrow but i know im not receiving any rpm in either wiring condition

Just really really getting me down now ive overcome some quite large challenges on my build now im being taunted by electronic gremlins !

Soo wish id found a sierra now in the first place ! Would have saved me at least 1k
