I'm pretty shure you have control over the DIY sensor mario :)

but it says nothing about built in pull up on their website?

i was reading this thread last night .
and it says that marios hall sensors are the same as diy
and that they have pullup built in

Is it running yet?
Addendum to Newtons first law:
zero vehicles on jackstands, square gets a fresh 090 and 1911, cabby gets a blower.
EZ3.6 Vanagon after that.(mounted, needs everything finished) then Creamsicle.

not yet i have only got about half hour a day to play with it .
it sounded like it wanted to start today then backfired then the battery started going flat .
so i am going to go through all my settings again and make sure i have the leads on right (106b coil )
and charge the battery and try agin tomorrow

Good idea, a low battery will cause weird at the worst possible times.

ddoes anything look wrong here
also i have the 106b coil it has on it A,B,C,D,
the golf firing order is 1,3,4,2
the type 4 is 1,4,3,2
so A should be 1
B - 4
C - 3
D - 2
i think thats right

I suspect A&C fire together, same for B&D, but I don't have one of those coils.

If that is the case, (fire them in test mode) they can only be 180 out or out of time.
Make sure they go to the right cylinder pairs in any case.
Should be able to check timing cranking, set for 0 or 10btdc, easiest on starter to pull plugs.(pull the injector fuse too)

Make certain the coil doesn't get warm sitting there key on
If so, dwell polarity backwards, some coil don't live long.
Not all logic driven coils are "smart". (self protect)

Have you adjusted the input amp?
(i assume the uS tach inputs are adjustable).

If you ever suspect you have fuel fouled/wet the plugs, its best to pop them out and clean with a shot of carb cleaner and crank for ~20 seconds w/injector fuse pulled.

Too much fuel is ~worse than not enough for first start, as if you foul the plugs you will probably kill the battery before it starts. Sneak up on it by tweaking reqfuel only at first, once you find a working number you can multiply the VE table and divide the reqfuel by same % until they are both in a sane range.

On recent MS2E ~100 for idle range gives good resolution, IIRC the max VW# is a 16 bit int, but probably won't be over 300 if idle is 100 unless boosted
(Once the hard limit was 255 like MS1, so only 8 bit resolution, I'm pretty sure that's ancient history now)
VE numbers in that table don't need or want to to be related to actual meatspace VE %
They are only for load calcs, more digits=more resolution within reason.
The reqfuel gets pretty small with big VE numbers though, they really need a divide reqfuelx10 option

Turn off WUE, ASE and accels at first (set everything for 100%)
Leave the accels at least off until you have a reasonable VE table.

Make certain your MAP sensor is working as expected and connected.
(sounds silly, but suck on the hose)

Gotcha, verifying the coil temp and output pairs in test mode/setting the timing with plugs out etc is still a good first step.

the 106b i had it wrong
A & D fire together and C & B fire together
as the golf firring order is 1,3,4,2,
so 1,4 & 2,3 fire together in the golf
in the type 4 it's 1,3 & 2,4
and it started straight up
i ran it for a few minutes .
just have to fix up my timing map

i was going through the ignition options/wheel decoder settings and i am not sure about the
fixed advance setting for my setup
(36 to 1 wheel/ hall sensor /106b coil wasted spark)
is it supose to be , user table or fixed timing.
also where do i set the trigger wheel eror(its a few degrees out )
