LB7: No response from ECM

[durallymax]

Last night after installing a DSP5 switch I went to do a full reflash on an 03 LB7 and it stopped 509k (out of 512k) into the process and froze, then kicked me out. I tried everything to try and get the ECm to respond and take a calibration but nothing ive tried seems to work. Tryed it without high speed, unhooked batteries for 15 minutes, but still everytime I try to flash it I get the message "no response from ECM."

I dont know if the ECm took a poop or what. I have another ECM out of an LB7 here, and was thinking of swapping them but wanted to see if there were any ideas before I do that.

Also wondering if I swap ECMs do I need a Tech II to marry the ECM to the truck or not?

Thanks much.

no you wont need a tech II but if you've not already and plan on flashing the spare with efi live,, prepare to buy another dang vin license.

the ecm is out of my truck and is already married to my flashscan, but once I buy the one for my truck i guess Ill need another dang license.

I got it going, swapped the ECM and all was good. Sending the other one to Guy@SoCal for him to look at/repair.
