So for some reason, after getting spark curve issues inline, when tuning ve table open loop, I get BLM? Anybody ever have that before?
I did a quick search and I couldn't find anything.
I'm tuning in $OD on a 94 GMC 5.7. I have a wideband installed to EGR channel to the 7427 equivalent (6395)
closed loop enable temp is maxed, and data log shows open loop.
BLM update min RPM maxed out.
I don't understand why BLM's are updating in open loop?
I went ahead and burned another chip with min BLM max BLM both to 128 and changed BLM step from 1 to 0.
Tune log entries
07/12/2020 20:38:36 Scalar: Minimum BLM changed from 105 BLM (0x69) to 128 BLM (0x80).
07/12/2020 20:38:49 Scalar: Minimum BLM at Idle changed from 90 BLM (0x5A) to 128 BLM (0x80).
07/12/2020 20:38:56 Scalar: BLM Step Value changed from 1 BLM (0x01) to 0 BLM (0x00).
07/12/2020 20:39:06 Scalar: Maximum BLM changed from 165 BLM (0xA5) to 128 BLM (0x80).
07/12/2020 20:39:14 Scalar: Maximum Initial BLM changed from 135 BLM (0x87) to 128 BLM (0x80).
07/12/2020 20:39:24 Scalar: Minimum Initial BLM changed from 126 BLM (0x7E) to 128 BLM (0x80).
I will disconect the battery to clear BLM and try tuning VE again.
Maybe I don't understand, but I was under the impression that all qualifiers had to be met to trim fuel, Closed loop enable, INT, max RPM, TEMP. Does someone know how the code logic works? Does it look for 1 before the other?
I have no idea. Weirdest thing to me to have open loop BLM's while INT's stay locked at 128
I thought with a Wide Band this thing would be easy to tune. I still think if it would do what I'm trying to tell it to do, it would be.
