    Well I figured out that I have a VSS and a DRAC, so that's cool. Should I take my A7 and put on E10 since I don't have the 4L80 ? There's a lot of debate on the F12 vs F13 as well, where should I put my A10 ?

    Also, I stumbled across an old thread on here about using BJYL on a LO5 w/ a 700R4. I think it was Fast355 who said that there was no better BCC to use on a stock LO5 with a 700R4. What's the consensus on that ? I put one through the editor last night and I am about to try it out.

    This is my pinout page from my 1990 Chevy G Body Wiring Diagram book. Might be handy to some. There's slight changes that are different from the 16197427 $OD pinout thread.

    So now it starts and then shuts off immediately. When I unplug the MAP it stays running. Is the MAP bad ? I have 4 single bar MAPs and they all act the same. Am I missing something ? Could all 4 be bad ? Can I get rid of the MAP ? Is a MAF better ? I need to get this thing running. It is now the only vehicle I have :(
