Having some problems with HP tuners. I bought and went through all the steps uploading and actually got to read my Vcm once and even saved it, but now it won't read. Getting that vcm failed at loc 6000 error checksum. Hp is trying to help me but has anyone else had this problem? Been working on getting this up and running for days. They say I need a tech 2 to reflash. The car worked fine before adding this software. What should I do? Any help would be greatly appreciated I really want to get out tuning.

 

first try disconnecting the battery for 10 minutes and then see if the car starts after that.

 

PCM has been previously tuned and the checksums modified from stock, I've seen this a few times with pcm's tuned with hypertech, diablosport & SCT.

 

Did you ever get it worked put I'm having the same problem
