Tuning help with Ostrich 2.0 and '92 Chevy G20 350 TBI with LPG installed...

[Dunksterp]

Hey guys,

You helped me out in a previous post here and advised me to grab the Ostrich 2.0 and the required gubbins.

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-Inj...light=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.
