What do I change the speed density calc to with a 383? In winbin it shows 159 for a 350.

 

The calculation used is L/cyl*223.157. So on a 350 you get 350=5.7L, so .7125L/cyl then mult by 223.157 you end up with 159. A 383 would be 6.3L (round to nearest tenth) so .7875L/cyl * 223.157=176 (round to the nearest whole number). This is at address $86DD in the ANHT hac or if you look at it in winbin it would be address $06DD. Get the hac from ecm guy webpage. Then view the winbin ecu file in wordpad or something and you'll find the parameters and their addresses and you can cross reference them with the hac just in case there is something wrong with the ecu file.

 

thanks
