[Syty] Possible 10-n-1 Problems...?

[DOlivares]

Todd (I assume), 

    I don't know if you're cognizant of the recent thread on the SyTy.Org List, but your Product(s) has come in for a bit of a thrashing.  I never went for it much myself 'cause I know how semiconductors, controllers, and such fail and I just wasn't getting the classic symptoms.

    However, the ECM-Pros on the List kept insisting I had a bad EPROM-- or defect in your 10-n-1 Switch and claimed I was wasting my time trying to isolate defective engine sensors and such.  Unfortunately, it looks like they might have been on the RIGHT TRACK all along!

Yesterday, I finally tore-into the under-dash computer and tried to remember what I did in there more than 6 years ago.  I removed every electrical connector and super-cleaned each pin/socket and then I removed your STG Chip-Interface on the MEMCAL.  I tested start/run on a slightly warmed-over engine in 70° weather and got slightly smoother results WITHOUT your Interface PCB/EPROM.  So I left the cable and dash-controller and PCB/Chip out of the car and buttoned back up with your "STG" EPROM still on the MEMCAL back.

Went out for food and the thing's running as bad as ever-- for about 7 minutes.  Then once full-warm-up is achieved everything is PERFECT!  This situation has been deteriorating slowly for the past 3 months and I've changed EVERYTHING on the motor except the ESD module (which would only affect my start-up in any case) and the EPROM.  I don't have a spare or my original stuff around where I can find it.  

I keep getting a Code 44.  I used to think the IAC was hunting all over like crazy but have come to realize SOMETHING IS SHORTENING FUEL-PULSES DURING COLD-RUN BATCH-FIRE SEQUENCES, i.e., only when the engine hasn't been run and the weather is "cold."  With the engine starving for gas it's only managing to tell me I'm running LEAN... gee, thanks a lot!

WHAT DO I NEED TO DO ABOUT THIS?  Should I junk that STG EPROM and swap it for the 9722E chip left on your PCB or send it in for reprogramming or WHAT???

HELP,
