Lost with TunerPro RT

[NomakeWan]

Read the BIN using Flashhack. Run the program, select $EE as your program, and click "Read Calibration." Then save once it's done reading.

yours should be 16202061 or something

[Gasnmyveins]

Mine is 16200901. I have it in Tunerpro RT.

I'm going out to the car now to see what I can do.

If nothing else, I'll get to sit in my car and tinker with it for a while.

[Gasnmyveins]

I'm inside again. I used flashhack to read and save the bin from my car. Now, how do I compare the one I downloaded from your site with the one from my car?

[steveo]

compare them using tunerpro would be best for a beginner

in tunerpro there is a 'compare' menu you can load up to 4 other bins to compare. so just load one into tunerpro and the other as a 'compare' bin

when you are browsing parameters you can see the selected 'compare' bin data there or easily compare them with graphs

then in 'tools' load the 'difference tool' where you can compare individual bytes from the loaded compare bins all at once and get an overview of the differences

this will label the 'known' bytes (that are mapped out in your XDF) but the others will show up as junk

there is some junk there though, in the region of 0x0000-0x2000 and 0x10000-0x12000 you can disregard any differences (this is the ram region), also around 0x0E00 you might see a few differences as well.

oh and before you WRITE a bin to your car please read this. it is rare there is a flash write failure with a healthy ecm but it's best to be equipped with knowledge if there is.

oh so there is a thinger called 'corvette security fuel enable' in your bin... that's the first goal you had right?

so you can unset that flag and save a new copy of your bin to flash and away that feature goes (always save every separate version labelled nicely in a folder just for your car, it helps later on)

now i THINK the security light is controlled by the CCM not the ECM so you might still see the light but i am not a corvette expert. since we have also hacked the CCM pretty good, in fact flashhack can flash that thing too if you take your whole car apart, we can probably figure out how to disable that too. but small steps.

[Gasnmyveins]

So, When the "set" box is checked , then that particular feature is turned on? If there is no check, then it is disabled?

[Gasnmyveins]

If that is the case, then both VATS and traction control are already disabled. the thing is, traction control works unless i use the switch to turn it off.

[steveo]

it totally depends on the option
there are often descriptive comments if you hover your mouse over an option in the parameter list

[Gasnmyveins]

No description when I hover over it. I've seen it in other sections, but not here.

Here's what I'm looking at.

[steveo]

okay so you have an ancient xdf file loaded not eex from my website and you are looking at the vats flag, you don't have vats, you have a Corvette with passkey
load my xdf in.category view as mentioned earlier in the thread and try again

[Gasnmyveins]

OK. i've got your EEX loaded now. Here's what Ive got now. Can you tell me where the passkey control is?
BTW, your "Dear God, please don't touch these" is a killer!

[NomakeWan]

I have working VATS in all three of my Corvettes so I've never tried disabling it.

That said, the security system on a Corvette is controlled by the CCM, not the PCM. Disabling the PCM-side settings is fine and dandy, and will allow your fuel injectors to come on regardless of what key you use or if you have VATS connected. However, the starter will still be wired to the CCM, and the CCM will still be expecting the correct VATS key resistance. To bypass this, either connect a resistor of the correct value inline with the CCM's VATS signal wire, or tear your entire Corvette apart, remove the CCM, and follow a special procedure to reflash the CCM in order to disable VATS.

I recommend the resistor trick, personally.

... traction control works unless i use the switch to turn it off.

PCM Traction Control is ignition retard.
Traction Control braking cooperates with but is separate from pcm.
Disabling pcm's Traction Control does not disable Traction Control braking.
