reset problem help !!!
using board ms v3 with msns-e q2...4 VB921 with 4 msd blaster ss coils...
i almost got no reset when i was tuning n/a...but now more i turn the screw on my boost ctrl more i get resets......
i get so much resets that the car is unusable !!
I checked all my grounds, installed a noise filter on my ms, ran a new wires from a independant relay to feed the ms...but still got resets
can my VR makes the MS resets ?
can the polarity of the VR makes the MS reset ?

I got a stable 14.12V+DC when idling !!
I looked at my spark plus they are champions RC9YC...and on there web site they said that they are resistor plugs....so !
last thing....I made a mistake qhen i've hookup my 4 VB921s...i'm in wastespark mode...so i'm using 2 outputs to drive 4 VB921s....I saw that on MS web site that i'm needing 680 Ohms resistor on each VBs...i was having 330 Ohms ones...this way i have been able to adjust the dwel to something that is looking fine....no more missfires
I think that my first problem was really hard missfires...that cause the ms resets....
i installed a capacitor coming from a ford coils pack on my 12V+DC of my coils and ground it to the frame....this might help out a bit too...
finally...almost no resets...but still got some...some times i can drive for 30 minutes without any resets and some times....that is bad...arround one reset at every 2 minutes....
so i still need to work on this....i think i will ad one more capacitor on my 12V+DC on my MS....
you have any other advices for me ??
thanks alot guys !

here is some updates...
yesterday evening, I did some more testing....and i think i fiwed up my problems...
I looked over the forum and i found that if the polarity of my VR is wrong, i can get some wired timing or ignition problems...so i started looking on google to find the polarity of my Ford VR sensor...and i found a draw of the connector with the pins.....so i have unhooked the VR and then tested with an Ohm-meter and i found that i was wrong with my polarity....i inverted the wires....and...BINGO ! seem to work..
but i said "seem"...because i will need to re-tune the VR pots cause i'm loosing the tach sometimes...but no more missfires or resets....
I'll tune my VR pots...and i'll update this post maybe tomorrow !
thanks all of you guys !

here is the draw i found over google !
but i'm very not sure about it !
now i got really bad rpm problems....
when i slaping the gas pedal...the rpm is doing spikes from 1200RPM to 400RPM...and the engine is doing a kind of cutoff...sometimes it goes over 1200RPM and then it seem to running fine...
I trim the VR pot the best i can with the tooth logger mode...
but you have the pig tail of the ford VR sensor ? with wires color i can look at a shop manual to find the polarity !!
I was having reset problems with the fan control...so now it is always ON !!

Hi,
from the installs Ive done pin1 of the ford 2pin plug is Signal (pin 24 of MS) and pin2 is the ground,
