Hi Dave😁
So I need to ask you a question…..yes software is a sequenced 3 part pain to install.
My question pertains to the software….it only goes up to 2013 and my Vette is a 2015, how do I get a more recent version?
This is on the memory stick that came with it….I guess a hacked version of GDS2.

So I took a video of the passenger side rockers.
I confirmed cylinder #6 AFM exhaust rocker arm is not moving.
So I have a collapsed AFM lifter.

Also, drove the damned thing 80 miles to get it back home so I don’t think one minute is going to make it go boom 💥

I just ran it for 1 minute to confirm the collapsed lifter because none of them appeared to be loose when I checked them after removing the passenger side valve cover!

So #6 exhaust pushrod was bent, so I pulled the passenger side head and #6 exhaust lifter was partially collapsed. Cam and lifter roller OK As well as lifter guide assembly. Replaced all passenger side lifters and guide assemblies.
Performed VLOM plug mod in lifter solenoid oil feed. Drilled hole in plug to match size of high pressure fuel pump cam oiler spray hole on rear underside of VLOM.
Also broke off 8 solenoid seals that mate with lifter activation towers below VLOM cover so that AFM cannot be activated.
Will turn off AFM system in ECM with HP Tuners software.
Awaiting new hardened chrome moly replacement pushrods, will change out all 16.
Should be done in a week or so 👍

Decided to finish it without the new pushrods which are on back order.
Put in new dexcool.
Pulled the starter relay and jumped the 30/89 terminals and turned it over twice for 20 seconds to build up oil pressure.
Sat in the pilot seat and it started after turning over for 10 seconds building up fuel pressure.
It settled down to idle in my heated garage with the door open in 15 seconds or so.
Purred like a kitten with no flashing engine icon any more…..all looks and sounds good.
Will reprogram ECM with HP Tuners this week to turn off AFM 4 cylinder mode permanently.
👍😊

Last night changed my oil and filter and programmed off DOD with my new HP Tuners which took 4 credits at $49.99 per credit plus the $399 cost of the interface adaptor.
Took it out for a spin today to get my wife’s Birthday gift.
Runs great 👍😁
The new hardened push rods are coming on Friday…..will install them when I get a chance.
