I having a problem getting my idle BLMs to stay at 128.
With car in neutral (1000 rpms), I'm at 128.
When I shift into drive (800 rpms), they climb to 150.
I have the BPW VS load table enabled and have changed the PW values in the first 2 columns (using GMECMEdit) from .38 progressively up to .84 msecs for the 800 rpm and lower cells. It has no effect.

Tried adjusting the PW VS batt voltage table for 14.4 volts.
That helped the "drive" blms a little (down to 137 BLM), but knocked the "neutral" blms down to 108.

Can't tweak MAF table #1 since the g/sec is abt the same for drive and neutral.

What else can I try??

 

THere is a post a few clicks down that has to do with BLms. I posted a caption to one of KVUs late posts that explains exactly how to fix the problem. I just did it again the other night when I got yet my second romulator, as a little test, since it rains here in PA every day now, and I couldn't leave the garage. It worked great once again.

 

I think I found the post you were refering to. It delt with adjusting the MAF tables. I don't think that will work for me since the maf readings are so close together between drive and neutral.
I was able to make some progress by increasing the PW in the 400 RPM row and the 800 RPM row of the BPW fuel VS load table which I enabled a few days ago and have been tuning in. The only thing that concerns me is that I had to increase the PW values a huge amount. This also lowered my 1200 RPM blms, but not too bad.

Using Winaldl, I recorded the following from the first column in the BLM text file.

I was at:
800 RPM= 150 BLM
1200 RPM= 128 BLM
1600 RPM= 127 BLM


I'm now at:
800 RPM= 130.6 BLM
1200 RPM= 124 BLM
1600 RPM= 126.6 BLM

The "in gear" idle quality seems to have improved a lot.

In the back of my mind, I'm still thinking there's a small vac leak somewhere, but I cannot find it.
