BLM cell stuck on 0, blm stuck too.
Hey guys,
I made some bpw vs egr changes on the $58 bin and have some better runing results:
RPM: 1150
Coolant: 195f
MAT: 131f
MAP: 46kpa
O2: between 450 - 700mv
Rich/lean: jumps around like it should
O2 cross counts: 242
INT: 128
BLM: 126
BLM CELL: 0
The BLM cell never changes. The BLM switches between 128, 127, and 126.. But it doesn't seem to relate at all to the int. WHen the int was at 70 with a super rich bin, the BLM still read 126-128. weird.
Why is the BLM cell stuck on 0??

The $58 mask only has two BLM cells, idle & cruise.
I still think the BLM reported is bogus though. Like I said, at 70, 140, and so on INT, blm stays around 126-128. Doesn't make sense.

read up on block learn memory
I have. Which is why this doesn't make sense..
Also the calculated airflow shows as 0.0
2 minutes of run time, generated 64,000 knock counts.
Then they go down to like 1100 and start going up again.

Run-away knock, hmm, open wire, wrong memcal, should have at least set the SES.

With the cyl select set for 8 cyl airflow calc is 0, all of the time. Only used for EGR so no big deal (maybe one other stupid thing too?).

It sometimes sets the SES, but no code..
Still can't figure the blm thing out.

Have you logged some data since tightening the exhaust. Leaks can make the blms vary greatly from int. Also, it is common for integrator to vary(depending on time int dwells). If you have log data then I can check it out.......if you like.

Tim,
I only know you as kvu.
scan data:
http://members.cisdi.com/~anesthes/7...s/saturday.adl
I havn't run it after tightening stuff down. Car was almost out of fuel, and I didn't wanna suck the tank dry. (cars been on the lift since october).
That log is in tunerpro format. No way of exporting it to a csv file at this time.

BLM problem is fixed. I think one of the egr enables was causing it.
I also removed "limit boost during first accel". I'm sure this has nothing to do with anything, but I was thinking it might effect fuel and spark.
I still get a ton of knock counts, but most of them were because the #1 rocket loosened up. The polylock wasn't tight enough, so the rocker was making noise. readjustted all the valves with motor running and hot, and its a lot smoother now.
Only problem is my IAC. Car won't go below 1000rpm, even with a desired idle of 850. Iac steps report 0 in the log. It might be because the blower is forcing too much air into the engine, so this might correct itself when I install the BOV over the weekend. (assuming the vac line keeps it open durng idle....).
So.. in all, the engine idles great. I'm soo please. Thanks for the responses. I have to fix a bent axle problem before I can drive around recording all the VE data, but then it should be good. I imported my old timing table from 8d, and modified the above 100kpa timing to reflect what my msd BTM did. So timing should be really close..
