Formal Request for COS5 for 1MB PCMs (04 GTO, etc)

[Kevin Doe]

Ross, my OS is 12587604. My ECU came from a US 2004 GTO. If you do that OS you listed, would I be able to use that, or how would that work?

Its been a little over a month since we heard anything official. Any progress on this?

[brokenfly]

if the cos5 ever arrives i will be glad but i will have to make do until then...

i am right now at 26 degrees total advance on the 150 single stage wet with no knock or plug damage...(actually for all of last year,80+ plus n2o runs at different shots and timing)...
backed down to 24 total in preparation for making this wet nozzle kit a dual stage dry direct port,hitting a 50 out of the hole(3000rpms),and lighting off the second stage 100 shot 1000rpms later for a total of 150...(maybe 75-75)...

simply going to set the PE to activate above 98% throttle,set fuel for 9.0afr and work my fuel afr up to 12.0afr while spraying until i get there...window switch and tps switch remain the same and manually activate the 2nd stage...

i really not spraying much,i just wanted to eliminate the fuel solenoid from the system in case it fails to open and since i am olsd a dual dry from the nozzle,letting the injectors supply the fuel is my goal...

I too would love to have COS5 for my 01 Z06. I could use it's added features with my setup.

If your running the original PCM in your 01 Z06, you should be able to use COS5 just fine.

About another two months have gone by, totaling three since we've heard from Ross. Are you still working on this? Any information you have would be appreciated.

I was wondering too... as Spring is near, and my friend has his Built 402 he wants to spray in his GTO we want to tune next month...
