Vortec to 0411 swap and info thread!

[Lextech]

Haven't looked to see if TunerCat has this option?

Tunercat does have that parameter. I always tell people to hook up the 4 Trans Range wires because I never know what software the vehicle may be tuned with and it saves headaches on my end.

Agreed - Tunercat has this parameter - at least for some Gen III OS anyway. See attached PDF as an example ...

I'd have never run them wires if I did not have to...

Here's the hex address... CAX file for EFI Live or whatever in HP TUner! 0x1E5C2 Gear Indicator (0=None 1=PRNDL 2=P/N)

Or just open all the 0411 tuns, make them bins, fix them in TunerCat and POOF! No more wires...

[Lextech]

I'm curious How or even IF that would affect the ""Crank Relearn Procedure".

I forget if I ever did one? Or did I do it with EFI Live V2? How does a manual trans do CRP?

All I really know about CRP is GM tech of how it's done and then a 50-50 split of if it is needed and then it's only to fine tune for misfire detection?

[Lextech]

I've never done one on a manual trans vehicle. But, I think it needs input from the clutch switch. Maybe setting the Gear Indicator to "None" does away with needing any of those inputs. I really don't know.

EagleMark, what's up with your Roadrunner? Was it the wiring issue causing problems or something more?

[EagleMark]

The ABS was a wire I repinned wrong and the issue with Roadrunner was from following EFI Live instructions that were wrong. All is well since.
