That makes no sense ony? I run both 32 and 64 bit laptops and no timing or any other issues. You never know though, dam computers!

That's what happens when you start the calibration with correct information! :thumbsup:

I swear I screw myself a lot when I look too much into things sometimes.....

The correct info on adjusting blm's seems to have cleared up the too rich condition on deceleration.

Oh, one other issue I need to look at is, being that the truck is outside in the morning, versus being in the garage when I leave for work, it seems that my in gear idle just after going into closed loop is pretty ratty. I'm thinking bumping up the desired idle c/l in that temp range up another 50 rpm.

Sound correct?

I don't know what is happening , but I have a differents on my desk top 32 bits and my lap top 64 bits same data log same adx. it may be my 64bit lap top it got attacked by iced about 2 months ago I redone it but it may still not be right. I will go back to worn out screen 32 bit this week end and see if there is a differents in data logs. that is why I ask what you was running, as a distributor or distributor less engine never seen that much timming without knocks at 60-70 kpa.

do you drive in decacselaration?

sheesh........:mad1:

Still having the rich blm's when letting off the throttle.

Now, this has me wondering if I need to go back to the beginning and make sure that the throttle blades and IAC are set properly.

What was the last log of yours I looked at? It was looking fine...

eagle mark your right [dumb computers both 32 bits show total spark advance 64 bit about -10 degrezz]. there was something wroung with my old 747 I have been playing with the first bin file you put lean cruise on a year ago not near as many knock counts. I was wondering what danmax last log was also an which bin. dint mean to hijacked the thread. it maybe may antivierase causing the different reading on the 64 bit.
