E38 / E67 VATS disable guide

[Taz]

New to tuning, I have a E38 with 6.2L L92 I have tried all fix information posted here and can not seem to get around VATS. I have 12614088 OS with Patch applied full reflash more than once and have even put the relays in circuit for starter and ignition circuit. Please advise. This is set up on my Superflow engine Dyno and ready to run if I could only fix VATS, sets code P0633. I have TIS and Tech II so I could install another OS if needed.
Thank You
Tom

Post your tune ... will take a look

Sorry to hijack the thread, we'll make another one to get further with the problem solving.
Taz - that was the first thing we tried, unfortunately, after filling with 5 gallons and having FFV on, we did not get it to even attempt to relearn the fuel.

Sorry about that ... no Flex Fuel available here ... forget sometimes that it may require a COS ... EFILive has a Custom OS Upgrade available for the 2010 Corvette E38 OS.

Here it is

Try this one ... remember to Full Flash it (OS and Calibration flash).


EDIT: fixed DTC and reposted the tune

Try this one ... remember to Full Flash it (OS and Calibration flash).

And it works!!!, what did I miss?Oh and first should have been Thank You

[Taz]

I just reposted it with the DTC fixed ... forgot to do this initially. Try the one that I reposted (rework 2).

... what did I miss? ...

Nothing really ... just a matter of understanding how the EFILive VATS Patch works ... some parameters get changed, some do not.

I notice that all the successful reports are with 2008 and older OS'. I'm working on a 2010 Camaro engine/E38 into a 57 Chevy. It uses OS 12637084. I've applied the VATs patch and loaded these parameters. I am days from trying to starting. Has anyone successfully used the 12637084 OS and did they need the resistor to simulate the starter relay?

I too am having the run for 2 seconds problem on a remote customer vehicle. 2011 Suburban 5.3L/6L80 swap into LandRover. Speartech harness, 12639835 OS, 12639900 cal.
12639835.calz calibration file v7.59. Has this been programmed out or do we still need to install the resistor?

Since I made the 2010 LS3 into a 57 Chevy post, the car has started. I was not present so I do not have exact details. The car has no exhaust so it was only allowed to run for a few seconds before shut off. There were several (successful) restarts, each for only a few seconds. The last start the engine was allowed to run for about a minute. No known issues. The file used the settings as noted above. NO 100 ohm resistor. Again: OS 12637084, Cal 12637083 and 12637084.calz. It is using a Hot Muscle Wiring harness.
