Everything I read saids a factory ECM is much better that any after market system, and much cheaper.
And I want and need a full functioning ECM, to control the transmission and the engines fuel system.
From what I have read the 7427 is nearly a plug in to replace my 165 in my 93 Van. A number of people report that a 4L80e really needs a 7427 over the 165.
SO I am looking for a couple of 7427s with a 5.7 and 4L80e chip.
