iceroadwrench Posted October 17, 2023 Share Posted October 17, 2023 Anyone know where to get one of these used? Preferably Canada? The boss has a down truck that needs one, I've got all the stuff to program one but the one I've got is grounding out the communications bus...

fjh Posted October 18, 2023 Share Posted October 18, 2023 Did you check with Mack ! They sometimes have these in the recon section the part number with start with an X! IF you can find the right parts guy! And you got a BIG BAG of Money!

Mackpro Posted October 18, 2023 Share Posted October 18, 2023 No more Vmac1 ECM’s available anymore. We have been doing the VMAC 2 conversation but the jumper harness is sometimes not available however the VMAC 2 reman ECM’s have been available about every time we checked. The last few we got junkyard ECM’s to get the truck going however we were stuck with what ever HP level the host ECM was set at. Best I remember you can’t Reflash used VMAC 1 ECMs to a different vin/truck. Also if you go the used route there were 10 degree and 20 degree Econovance VMAC 1 engines that used different software to control pump timing. Last option is send it to GoECM. We had a few repaired that worked great . However one was fried beyond repair. Sadly VMAC 1 stuff is getting very hard to get. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/73439-vmac-1-12ms45m4/#findComment-540582 Share on other sites More sharing options...
