Hey guys,
You helped me out in a previous post here and advised me to grab the Ostrich 2.0 and the required gubbins.
http://www.gearhead-efi.com/Fuel-Injection/showthread.php?8819-92-Chevy-G20-350-SBC-TBI-with-LPG-installed
I've now purchased this and got it all set up and installed on my 299 ECU.
I've successfully loaded on a BIN file : AWLF 92 C-G-K Truck 5.7TBI 700r4 california.bin from this thread : http://www.gearhead-efi.com/Fuel-Injection/showthread.php?380-16146299-ECM-Information-99&highlight=16146299 and it started 1st click of the key. So happy that's working.
Now, onto my tuning... My fuel is controlled by the LPG system, so is the only thing I need to edit going to be the main spark advance vs rpm vs load table?
I saw there was a natural gas conversion bin file in that thread, however there are A LOT of changes from the standard BIN and I'm concerned that are completely empty tables, like the Maximum knock retard vs RPM (in WOT) and Max knock retard vs map.
I was considering just copying the Spark table from the Gas conversion and pasting it onto the standard BIN file. Would this be a mistake?
Oh, I also have a wideband O2 sensor to make sure my AFR is good, is it possible to wire that into the ECU?
Many thanks for your help so far. It's hugely appreciated.
