Hi GM400 truck people!

I am using a stock L31 in a project car and am looking to control the stock injection with a standalone Speeduino ECU (Pretty much a poor man's Megasquirt.) Has anyone here had any experience with this?

Does anyone have the spec sheet or manufacturer part number for the injector that comes as a part of the retrofit spider? I looked at a 2001 van BIN file and found that it has the flow set to 23.09lb/hr. I am specifically looking for thinks like injector dead time/injector open time, and battery voltage compensations.

I've been looking through the 2001 van bin with TunerPro to get some base values, but found pretty quick the stock GM PCM works way different than standalones and has way more tables before its final fuel calculations... So any help to get started would be much appreciated.

Thanks guys.
