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

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

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?
G1204:Yes
G1205:Yes
G1206:No
G1208:Disabled
G1209:No
G1210:Type 2
G1211:Yes
G1213:No
G1214:1
G1215:1
G1215:1
G1216:Yes
G1217:15
G1219:Disabled
G1220:Not Used

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.
