Let me repeat this since it may have become lost in my last long post:
Having the BLM at 90 or even less at the end of warm up was accomplished by aggressive Alpha N changes.
I thought it was at 90, but when I got aggressive with the Alpha N, it went just a shade below 90 (less than I expected) and the AFR stabilized which cured the racing and other start up problems in large part. (I would still modify my advance curve first tho since if it is wrong, the low rpm performance my be doggy).
In fact, now when it starts, it usually goes up to about 1800 rpms (due to cold enrichment) and then drops down to 1100 idle just like it should within a few seconds. I notice that if it does not hit 1800 on start up for a few seconds and then drops to 1100 idle, then ......... guess what is messed up? TPS or IAC.
