Ive been doing alot of research on here trying to find the answers to my questions.. i went to a reputable shop on here in cumming, GA and they told me my engine/ecu from 03 suburban will work fine even though its drive by wire i can convert it to cable and he will set it all up for me.. After 3 changes to the wire harness that he jacked up i noticed the tp sensor and iac isnt reading.. so i bought a hp tuners credit and realized the ecu read as a 03 suburban.. from research ive done it needs to be converted to either a 03 express van or 04 gto ecu.. How is this done with hptuners.. or is it even possible.. do i need to buy 2 more credits for the license for the file i got from the respository and then do an entire write and rewrite the ecu completly or whats the best way to go about this.. only a 04 gto hpt file is online does someone have an 03 express van file ive read its better to do that one.. The shop i went to refuses to answer the phone and its over an hour away from me.. if i can just spend a little extra money and get it going where i dont have to deal with this shop id be happy.. im probably going to need a pinout for the 03 express van ecu too.. cuz i doubt this dude hooked the tps or iac to the right pins.. and so forth.. PLEASE HELP!

thanks!

Read that, then make sure your PCM can support DBC. Finally, resistance check the TPS/IAC circuits the shop installed to make sure they were put in properly
