Is this the correct way to set up a distributor?

You're running the ignition module? I thought you rewired it for 12 volt. Oh well.. at least you got it running.
George: You're old FAST is fine with the stock crank sensor in the stock location. You have a billet interuptor ring on your balancer.

Sorry for the confusion, i am not running an igntion module, but the buick strategy in the dfi is based on the c3 ignition module, thats why it doesn't work. I did wire the factory sensor for 12volt but for some reason the timing is out when the gen7 processes the signal regardless on how it set it up in the dfi
George, I just got it together and will be testing it soon, it starts well and runs well so far. Now I can use all the rev limit controls and safety's built into the gen 7 without worry. i will never go back to the c3 style setup.

Norbs I have done 5 of these now with no problems like you describe. The dfi will work fine with the stock sensor 12 volt and hall effect. Put 9.91 on simpsons car. Steve went 9.66 at Norwalk same way. If I can get Chris to stop reading your post about it he will be at Indy with a distrib set up same as the others.

Thank you Norbs, Speedstar crank trigger wheels and sensor brackets are the only ones designed as a dedicated system, unlike all other generic crank trigger wheels , that need alot of modifications to work. When you order my kit , you will recieve a billet T6 6061 Alum. crank trigger wheel and sensor bracket that is designed dedicated for a BUICK TURBO V6 ,the ECM , and the BALANCER / hub that you are using, It is indexed and marked TDC, also precision indexed full lines at 10..20 and 30 degrees, then half lines every 2 degs. from 10 to 38 degs, .Next the wheel is phased indexed to the ECM that you are using. I have designed all the trouble out and put more value in. These are the steps to use them. First, with the engine at TDC, bolt the crank trigger wheel on with its TDC line at the engines TDC pointer, next bolt the sensor bracket on and install the sensor in the adjustable slide at either the 6 , 50 or 60 deg. reference mark on the wheel, depending on the ECM that you are using,The 60 deg.setting is for an engine that revs 7500 rpm and higher Enter the crank ref deg. number[ GEN7- 6 DEGS., XFI- 50 DEGS.],next go to the ECM timing map and inter 20 degs in a group of cells at 2000 RPM, next START THE ENGINE
and bring the rpm to 2000. With a timing light on #1 cyl. wire , check the initial timing, if it is 21 degs, move the sensor ccw 1 deg. If timing is at 19 degs, move the sensor cw 1 degs . YOUR TIMING WILL THEN BE PERFECT and smack on the map. So besides it working perfectly and making it PLUG AND PLAY, it looks very nice on the engine. This product is a needed advance in timing hardware design and is patent pending. I have produced crank trigger wheels for alot of popular professional racers and engine builders, and took part in R&D on the first DIS ignition that was fully programable with 8 timing curves and 6 spark duration settings and entered the market under the name , FIREPOWER DIS.....

IME the factory crank sensor setup works ok into the 7's as a digital crank sensor input. And saves considerable cash. But one problem is, the factory strategy routes the crank signal to the CCCI module 1st. When you remove the CCCI module you then have to take proper action to get the crank signal to the ecu properly. If I recall the LT1 (and the old 5.0 F*rd TFI for that matter) has the same crank ref angle and basic approach (considering the crank ref pulses) as the Buick approach and is basically equivalent. Can make either of those boxes work with the distributor. One caveat, if you drive a points type trigger input on an ignition box for the spark you need a rising edge signal out of the ecu to trigger it in the right spot. The FAST points out wire serves this purpose. The stock Buick system adds a Bypass signal to the CCCI, but who cares with a distributor and no CCCI.

You have a good point, but there is no adjustability to the crank sensor angle. I have tried all the settings and my timing was still 25 degrees out, i really can't explain why its so far out, unless i have a problem with the box not accepting the changes i am making .
