Well i got a frankenstain wo2 system and all i got to read was my idle and wot, before it got streched and mess somthing up and got code 2 on the reader. but what im thinking is that my idle is really lean like 18-19. so maybe if i richen it up a little it will help that surge.
So start the truck and let it get up to temp and in closed loop and see what your WB reading is when the truck is idling smoothly, then match it at cold startup in open loop. Surely you can manually put the truck into open loop with the EFI-Live software. Bounce back and forth from open to closed loop adjusting your open loop idle fuel mixture until it runs as smooth as the closed loop mixture.
See my truck data in the "My Garage" section here... http://www.ls1truck.com/forums/my-ga...tml#post191709
Ok I will try to do that tomarrow if i can get my wo2 working agian. With reports.
OOO just a thought. Will that work even if the truck is already hot since it does the same thing when worm.
