I have been tuning my idle and VE since a recent cam upgrade in my 383. I went to a much more agressive cam and am running lucas 42# injctors. I have noticed that peopler rarely if ever, change the timing offset in B3702. I know the injector timing is an offset in the injector firing based on crank-based triggers.

My question is... is this a constant with all LS1's for example? Let's say you increase stroke and then increase cam duration, and even have some cam advance ground in... shouldnt the injector timing be altered to better match the earlier opening of the intake valve?

I am going to try and play with this... but I dont know what to watch or log to see the effects.... maybe AFR? Richer means a more complete burn?

I am open to suggestions.
