Simply Volvo Posted February 26, 2013 Report Posted February 26, 2013 Can someone post up a high res photo of the inside of their m4.4 boards? I wanna start getting some datasheet for the various IC's so i can figure out whats going on.
optimus prime Posted February 26, 2013 Report Posted February 26, 2013 i could take one of my 98 na and my 97 lpt
Simply Volvo Posted February 26, 2013 Report Posted February 26, 2013 i could take one of my 98 na and my 97 lpt Yeah do that. Id like to see if the turbo and non-turbo ecu's have similiar hardware.
optimus prime Posted February 26, 2013 Report Posted February 26, 2013 ill do it tomorrow after noon and post here

I wanna start getting some datasheet for the various IC's so i can figure out whats going on. Is the picture included with MotronicSuite not good enough? I can get a high res picture of the front and back if you need something better.
Simply Volvo Posted February 26, 2013 Report Posted February 26, 2013 It's pretty good but I want to see if there is a hardware difference between the non turbo and turbo
Volvo5.0 Posted February 26, 2013 Report Posted February 26, 2013 It's pretty good but I want to see if there is a hardware difference between the non turbo and turbo The hardware appears to be the same, at least it was on the m4.3 I did for my son. I flashed a non-turbo m4.3 ecu with the Euro R manual file (626) and it worked fine. BCS was fully functional. M4.4 may be different though...
Tightmopedman9 Posted February 26, 2013 Author Report Posted February 26, 2013 M4.3 I know has the same internals, but M4.4 I have heard does not. If someone could take apart their M4.4 N/A box we could compare the internals.
Johann Posted February 26, 2013 Report Posted February 26, 2013 M4.3 I know has the same internals, but M4.4 I have heard does not. If someone could take apart their M4.4 N/A box we could compare the internals. From what I can see it is missing a couple of components. From what I have been told the NA 4.4 is missing the BCS circuitry.
Simply Volvo Posted February 26, 2013 Report Posted February 26, 2013 Been doing some assembly work. Working through the initilization code. Hopefully I can disable the checksum check and then find the main loop. Also I wanna post up the memory map for the ecu and how it's memory is configured.

Tightmopedman9 Posted February 26, 2013 Author Report Posted February 26, 2013 Compared to a 98 LPT ECU (610) these are the differences:
