Hi guys, Patrick told me about a guy with a 2007 5.3 in a Volvo that has AFM
working- we should look in to that. We guess he has a volvo in his alias name, but we are not sure. He is posting here on the EFIlive forum..
Does anyone have an idea?

Ok this type of stuff intrigues me so I started doing some poking around. The 5.3L LS4 (07+) has a hard input line to the ECM for the Brake Vacuum sensor and uses an E67 controller. You guys are using the E38 for these conversions correct? Let me see if I can find a correlary here..

I'm using an E38 ECM. There is no hard wire from the sensor to the ECM. It goes from the sensor to the EBCM then to the ECM via bus. The sensor appears to be a simple three wire power, ground, signal sensor akin to a MAP.
I'll try and upload the wiring diagram.
I just pulled up the diagrams, yeah easiest way I think other than maybe begging ross to remove that part of the enable code would be simply spoof the data. Find me someone in detroit that has this and i'll take care of getting you the data you need.

Hey guys, it seems that we have some movement in this matter.
Very good thoughts from what I read so far. I just want to point out one little thing before we run to a GM dealer, have a suitable Truck for a testdrive and pull out a CAN analizer...
Is the missing booster sensor message really the missing link for enabling AFM?? From the stuff I read it seems like that, but only a visit at a GM dealer with a Tech II could really proof what AFM condition is missing.
So for all comming swaps a system patch isn't that bad at all??
I hope we will have some comments from Ross in this matter..

Thanks for the offer GTPprix.
Were not sure the BBS is the inhibiting factor. In fact there are a lot of variables that will disable AFM. Seems the BBS is the one we do not have control of.
Here is a list of disabling factors.
Well if someone can get me a truck here we can unplug the sensor see if it no longer operates then spoof the data on the bus and see if it operates. Should be a relatively easy test![]()
