GM ECM for 455 Poncho/Hartman book

[Thomas Matthews]

Wow, did I have my head up my anal orfice.... What I was talking about
was a 165 ECM, the 86-89 TPI one... Someday I'd like to boost it too,
but that's a long while down the road...I was going to go the MAF route,
but the cost of finding a couple of Bosch MAF sensors for tests are
really prohibitive for me... The Bosch MAF's run on a voltage system,
whereas the much higher flowing LT1 MAF uses frequency variation... If
we could only hack the 94-5 GM LT1 ECM totally IMO it would probably be
an ideal DIY controller, but it's likely going to be awhile before it's
hacked like the 747 and 730 ECM's...
The Hartman book has been an incredible resource, almost as good as this
list... Just don't forget to keep your mailer set on sending plain text
messages.... <grin>
