Not past MBT for that given scenario of load by any chance?

Has anyone had luck with tuning on a C4 vette, 93 model with electronic auto? Customer has sent pics of the ecu but the lack of numbers on the case exterior have me unable to identify the ecu easily and hoping someone may recognize it.

Yeah, if using the flash pcm you would need to load the VY NA flash enhanced bin, then tune it to support the boost (use timing etc from the memcal based SC tune). This is what I was referring to, just to clear it up. L67 injector rate and fuel tables/ settings among other things. Assuming someone ...

VT/ VX L67 harness are compatible with eachother but for a VY you will need to mod the VY Eco harness or use a VY L67 harness and ECU. Body connections are different to earlier models.

Best way would be to adapt the VY Eco harness and get an L67 tune flashed onto the VY Eco ecu which is non memcal

Best state of tune for that combo would be to let the trans builder sort it out with his hard parts set up and shift kit. All the trans tune should need is commanded shift duration times to match the mechanical capability. Spend the time getting things right especially on the 2-3 shift of course

So I've just got my hands on a VY Calais L67 and looking at an ls1 WH over the weekend as a donor vehicle. I understand I will need to buy a VY PIM and loom. Can I use the V6 bcm and relink with new pcm/pim? Will the dash loom need to be replaced, or just the engine loom? Is it plug and play like t...
