First , install a fuel pressure gauge , mount it on the windshield with
Ty-Raps or something so you can read it through the windshield while your
inside the car , DO NOT put it in the car , unless you want to go out and buy
an electric gauge (about 80-100$) .
You do not know that the fuel presure is right at all times unless you
have a gauge .
Does your TPS meter read correctly ?
Does your IAT sensor read close to the temps underhood ?
Does your CLT sensor read like you would expect ?
The fact that the car will idle is a good start .
The fact that you can drive it with no vacuum to the MAP Sensor is amazing .
If ALL of the above is working properly , it sounds to me like your
VE table is completely wacked .
After you verify the Fuel Press. , TPS , IAT and CLT readings
are all where they should be you can go to the next step .
"Export" your "VE Table.VEX" and add it as an attachment to your next Post .
I'll get an E-Mail automatically when you reply , see-ya then .

No , the spark should be whatever your Advance Table says it should be at
that particular MAP and RPM Bin .
You are probably thinking of the "Limp Home Mode" built into EDIS .
The only time the timing should be "fixed" at 10 degrees is when
EDIS is not recieving a SAW output from MS .
If your timing is staying at 10 degrees you need to check your wiring
and/or the ignition setup in MT . Something is not setup right .

well im in way over my head
the 10 BTDC thing i got from the setting up page says this
"After the engine is started the trigger can be fine tuned by setting a fixed advance (for example, 10 degrees) and adjusting the trigger angle until you see 10 degrees indicated on the flywheel using a normal timing light."
but it only stays at 10 when it idles and when i rev it with out the map plugged in it will go advance higher than 10
if i try to rev it with the map it well back fire out of the intake from cylinder 2 and 3 i think it was
and your tell me that if everyone unpluged there map valcum line they woulnd be able to drive it?
wow i feel like i have a long way to go
but ill go saturday and find out some more and see if i can give you some more feedback

My Bad .
Sounds like you are running other than the standard B&G Code .
I'm not familiar with the other Code Versions .
Do you know why you have one of the other versions ?
In other words it would help if I (or anyone else offering help) knew
exactly what features/modifications your engine has and what you expect
to accomplish with MS .
Some of the stuff that anyone would need to know :
Is your engine completely stock or what has been changed .
Turbo ?
Cam ?
Compression ?
Direct Port Injection or TBI ?
MS-I or MS-II
What Board version 2.2 , 3.0 etc.
What Code Version
If someone else setup your MS and they won't talk to you anymore ,
and you don't know what's up you may have to start over with
setting up your MS so that you are not in the dark .

Well alrighty then......
How much do you know about how engines work ?
Do you know for instance what size injectors you have , that is ,
how many pounds per hour they flow at a given pressure ?
You may have to spend alot of time doing Google searches on the Internet .
You may be suprized at how much you can learn doing this .
If you don't have a fairly good grasp of how and why engines work ,
then I can't help you , I just don't have the time to do this step by step
for you , sorry
.
If I were you , I would start out by reading everything on the MS website ,
and everytime you run into a word you don't understand , stop and do a
Google Search on that word until you can understand what you are reading ,
and remember , sometimes pictures are worth a thousand words .
If I'm wrong let me know , I'll keep watching this thread .
P.S. you were supposed to send a VEX file of your VE Table ,
if you can figure out how to do it , go ahead and send it .
