Good day all.maybe someone can answer this.I have a distributor from a 92 4.9L Deville engine.ordered parts to rebuild. Realized after that the star wheel for the pickup on this has a missing tooth and hall effect sensor.I'm using a 7427 in mpfi mode.my question is will the missing tooth cause any issues with one drp missing. I'm currently running an 89 4.5L distributor and it has 8 teeth so no issue.just looking to find out if the Missing tooth dizzy can only be used with the 2240 ecm it came from for sfi.thanks in advance for looking.

The missing tooth will cause a misfire problem with a non-sequential injection computer, and this setup can only be used by the matching ecm for it......unless you are up for a little crazy.......such as using a speeduino controller for spark control only.

The speeduino is very universal, and can be used for any type of missing tooth setup or pickup. However, it can only be set up for bank-fire injection on a v8, but for spark control, it would be fine. Large spark table, and can be configured for boost, nitrous, fan and launch control. Just tie in to the purple/wht wire <HEI REF> for input to the speeduino, and hook it up to control the tan/blk <BYPASS> and the white wire <EST> from the distributor, and you can fire 1 coil or 4 coils (waste spark), Depending on what you want. Tie in at the MAP and Coolant temp sensor signals, and you are set. The rest is setting it up in Tunerstudio. Just not sure if crazy is the path for you. heh.

Thanks for the reply.just what I needed to know. I do have the oe ecm but at this time I guess I'll rebuild the dizzy that's in it. The speeduino sounds interesting but maybe above my computer skills.great info though.thanks
