questions 101

[Jason Weir]

Ok we learned the other day that 0x29e was MPH to enable closed loop,

I have a value of 0x06 at 0x29e

0x06 = 6  (MPH is 0-255 I am assuming)

So the ECM wants 6 MPH before going closed loop, must be a switch to
ignore VSS at idle and go closed anyway if the other factors are met.
What about those not running VSS, I am not and I still go closed loop at
idle and cruise.  What is 0x29e for?

 There are similar questions for 0x29f which is TPS to enable closed
loop

I have for 0x16 for a value at 0x29f

0x16=22
22 / 255 * 100 = 8.6   (TPS % = byte/255*100)

So am I to assume that off of idle the ecm looks for 8.6 % tps to go
closed loop?

Ok to sum things up the ECM wants 6 MPH and at least 8.6 % TPS to go
closed loop once its off idle, hmmmm something doesn't sound right.  I
will try to set both settings to 0x00 and then something higher to see
if it has any affect on going closed loop? I'll let everyone know
shortly.
