Looking for a Stock 5.3 Liter / Manual Trans Flash / OS 12212156 .cal .ctz, or .bin

[dave w]

I might be asking for a flash that does not exist? It appears manual trans were only available with the 4.8 and 6.0 liter engines?

Maybe someone has a VIN # from a vehicle with the 5.3 / manual trans that I can then purchase a flash for.

Thanks in advance,

That file seems really strange. I thought all manual VSS setups were 19 pulse not 40. Plus it shows air flow in the P/N tables. Most true manual tunes do not have any data in the P/N tables for airflow. I really think its a segment swap.

I looked through the repository at HPTuners and only came across 3 files that were 5.3 with a manual trans. The only one listed as stock was a 2006 Avalanche with 1252075 OS. You might have to use something with a segment swap if you need the factory manual trans stuff.

I helped out with transplanting a 5.3 into a 67 C10 / with a 3 on the tree manual trans. Currently, the 5.3 experiences an occasional stall during DFCO. The C10 has the brake switch input wired to the PCM and a Dakota Digital 8K VSS, with the appropriate changes to the flash. The easy solution would be to flash a modified original 5.3 / manual file into the PCM. Looks like the flash solution is not going to be easy.

I agree, the flash linked above appears to be a modified .bin file.

The decel stall could be a combo of air and timing. Idle and low RPM timing control is setup pretty different from auto to manual. TO get you going, I would take a 5.7 manual setup and modify for 5.3. I know the cams are different but the early LS1 will be much closer than running the auto tune.

if you can get me a VIN I can pull one from TIS. My 15 min of searching the web I only found 4.3 manual trucks..

From an Autotrader search
Maybe:
1GCEK14V32Z186112
1GCEK14V72Z159429
1GCEK14T02Z183263

I think one of these is a 4.8 / Manual, don't remember which one.
