new 350 installed and running rich
Well I've been reading the posts, but I've got to go to court this comming monday and my car is running way too rich and won't idle or run very well. I've got an '85 camaro so it uses the $1F mask, but I can't seem to find any support for the $1F ecu/xdf file except tunercat (they do have it right?). There is an EPROM in it and not just a PROM right? I ordered the pocket programmer and teh UV eraser, but they were out of the 2732 chips that I needed so I thought I'd use my own. I was thinking of trying one of those '85 vette bin files, but will I have to change something for AFR seeing how I am running 30lb/hr injectors?
The 350 I put in is all custom and built by me. It's got a custom, dual pattern cam, self-ported heads (they were 76cc heads, but had them cut .006" so I'm probably getting about 9.0 or higher compression), previously had and still has short headers connected to a flowmaster exhaust, for now because of money limitations I am using the stock intake, but will get the holley stealth ram later, arp bolts in the rods, slightly used LT1 pistons I pulled from my other project engine which still has a way to go, and of course 30lb/hr injectors.
I just installed the demo for tunercat and seeing how I am 30 days to evaluate it, can I buy the $1F ecu file from tunercat and justprogram it that way or do I have to buy the $70 program before I can get it. That ecu d

How much cam are you running?
30# seems pretty high for a TPI-intaked engine. The TPI should choke it off long before you need 30#.
If you have a healthy cam which needs even less fuel at idle than normal, and already have the "somewhat big" injectors for the engine, AND the computer still thinks you're running 19#, well...yeah, i can see how you'd be rich at idle!
My advice would be:
swap in some 22# or so injectors to get you by for the next few days/weeks. A used set of LT1 injectors should be available on ebay or somewhere for under $100. Even the stock injectors would be better to get you by for now.
Then, look into a computer swap. You'll find a vast amount more tunability and help with a '730 or even '165 setup.
