First Burns

After about about a dozen burns, I finally got the BLM's below 128. I had to lower the fuel inj constant to under 19 lbs, (I'm running Accel 24lb's). It still idles at a around 140 BLM. I'll have to start adjusting the VE tables.

I assume my goal is have it running at 128 BLM at ALL times, right?

Thanks for everyones help, I couldn't have done it without this BB.

Hmmm, that is too much "off" for 24#, and generally the programming tends to be overly rich than overly lean - are you SURE that you didn't get 19#s by mistake?

On the idle, if you are SD, you can give extra fuel to the lower RPM (600-800) around 35-45 kpas. But often, the problem may be a lower voltage while idling, especially if you have underdrive pullies. Changing the Battery Voltage vs Injector PW usually helps with idle, especially if you are noticing a voltage drop while idling.

What mods, which ECM, etc?
