Today the engine becomes even quieter but with more noticeable power @ 70% ! Also the intake,tb & air plenum have cooled down significantly! I haven’t done a heat temp check but I know before you would burn your hand if you placed it in the intake manifold now you could keep your beer cold after a spirited drive ! E85 was a good choice! Forgot to add that to tink,tink,tink from the motor cooling is gone completely!

Filled up @ 80 % now oh man it uses the fuel like it’s going out of style! I’ll be switching back to the 40-50% blend after just a little putt around I’ve used a quarter tank but the power the power let me tell Ya !
Looking for solution..can I simply swap a pcm out of say a suburban or other flex fuel pcm at the time to recognize and receive correct internal adjustments on its own !

I switched from E10 to E33 last summer. Helped a LOT with limiting knock and allowed me to add a few degrees of timing. My setup was knock limited prior to MBT with E10, V3Si and 3.6" pulley. Yours may need more ethanol but it may be quite a bit under E80 which would add to the miles per tank.
Different pcm and proflex’s higher bar fueling should resolve the car’s ability to use both devices as it should. I intend just to reflash my current tune into the unit and let my tuner guy hype things up on the flex fuel cell area ! Then maybe the car is tuned and ready to run a 110-115 octane ! If need to be !

I thought the proflex was already doing it all on it's own, why bother with another pcm and if you did get another pcm then what would be the point of the proflex??
With a p59 u still need access to 4 bar and so on fueling. From what I read 3 bar is max on the p59 so pro flex pro is still in favor of making correct fueling rates the pcm will still adjust. This for me is a must swap I wish I had came across before long time back !
So after some research the p59 swap I won’t need. The 2000 pcm is equivalent of the 411. I maybe have already flashed it long ago when I switched the map to a 2 bar and I just need to check out the fuel tables and copy ethanol tables from the Tahoe or whatever file compare and 0 out edit changes left unchanged
I almost ordered a ls3 12.5 to 1 but then after some research the car already makes equal power and I can further enhance it by simple a pulley and whenever I get off my lazy and swap in my cam shaft. Port and dual spring the heads while there off. I read a guy had some flowing 400cfm . I figured save the 4300 and make more power with the parts I have. It’s almost done except for some de greasing on the differential from a previous owner leak and oil pan where the rear main had leaked over time .
I’ll contemplate a while on tearing it down again . I would like to grab a few more things to do 1st. Like the e brake shoes and a throttle body spacer with nitrous outlet. I was think of tapping into the gas tank with my 100psi snow performance pump and blowing e85 into the air charge pipe just to add the wtf factor !

Ordering up some mid length black ceramic coated . High flow cats .
Got the sound system all done . With 7’s & 4 1/2 in the doors, subbed/amped/doors insulated . Gotta redo the rear pillar side speaker as well now with some 6.5‘s and insulate All that . Diamond 3m sound proofing lol it works ace .

hptuners could have solved that in a few mins with no drive cycles lol
Why does SD pull 172 & 175 rich 1&2 . Just a question As pcm isn’t capable of making adjustments needed to lean it not within its stock parameters! How to say it’s ok ? It’s fine ?
it need be rich not leaner then a pork chop.
