I don't have any experience with an aircraft engine. I'm a touch nervous even posting in the tread asking information for an aircraft engine.

I don't have a link to share for a TBI installation. The DeBiase EFI link (http://www.slantsix.org/articles/dib...conversion.htm) is an awesome overview of a GM EFI Conversion. Most of the information on the DeBiase link will apply to a TBI conversion. I would suggest using the under hood 1227727 (aka '7727) ECM for a TBI 4 cylinder application. I don't remember which years GM used the '7727 with TBI 4 cylinder vehicles, 1989 ~ 1992 most likely. The 1227730 is an under dash ECM that electrically identical to the 1227727.

To operate fuel only, I'm thinking only the MAP Sensor, TPS, and a Distributor Reference Pulse DRP are all that would be required. An MSD 6A box can supply the ECM with the needed DRP.
