I've been tuning my 2000 Monte Carlo for the past two days, inculding MAF calibration, tuning the VE table, and further tuning of the VE table with the narrowband for low rpm drivability. I started tuning the spark table today after figuring out how to get the histogram working. What I don't know is how much timing is safe for the low end. IE under 3000 rpm and under 0.40g of cylinder airmass. The only way I know to street tune timing is to keep adding degrees until I hit knock, then dial it back. Which is what I've been doing for the top end. But I'm not getting any knock in the low end. The base map on a stock tune at 1400rpm and 0.36g airmass is 19*, I got all the way up to 32* without any knock. Am I going about tuning my base timing table wrong?
