someone finally comes along and does an e85 build and puts out 400whp with 2.5" exhaust piping and the jbo has to stand back and say "omg that's not safe, this isn't correct, that isn't correct!".
who the @!#$ cares if it's "correct"? it's this guys car let him do what he wants to do, i don't remember seeing anyone else build a j for e85, and there were alot of people that didn't even think it was possible. now here it is and we stand back and scoff?
@!#$in losers. props to this guy for doing something different, which apparently is not well excepted in the j world.

This is still far better than the nothing we had in 2006 to tune with, lol.

I understand tuning has been done without them but thats because the tuner is familiar with the Jbody PCM correct?
Why dont we promote more stand alone systems here then if Hptuners is not willing to help us? Heck i would hate to have a 500+hp cavi but could only be tuned to 350 or 400hp due to the limits of hptuners...

Your pcokets aren't deep enough.. Its a dead platform that we are honestly lucky to have support we do have... And you can have a 500whp+ Jbody... I have done a few! As for Standalones, most people here are a bunch of cheap asses.... Why would they buy a PCM that is more than what 90% of the cars on this site are valued at?

jk but for real. Do some Math and Chemistry and understand how the sensors of vehicles work with their computer and you will realize this works.
Ethanol and Gasoline have different chemical formulas so when they burn they break apart differently. So the amounts of oxygen in the exhaust could be different. Idk the comps of of the top of my head but its something to consider.
It has been considered when you balance stoichiometric equations. Stoich for one fuel means that there is no o2 found in the burnt products, which also means that with another fuel there is 0 o2 in the burnt product at stoich, so regardless of how they break apart, stoich is stoich. this is the reason you need to flow 1/3 more fuel with e85, that is accounting for the difference in the need for more reactant to create the same stoich burn.
If anyone wants to bring an intelligent argument to the table please do. till now everyone has just been a neigh sayer and has yet to back up reasoning as to why this will not work. If you want to argue that it is unsafe to boost and run e85 than you are also saying that it is unsafe to boost and run gasoline on our computers. Boosting in general on our computers doesnt allow proper fueling and tuning, but till someone validates an argument as to why e85 isnt as safe as gasoline, step down. Our computer has no knowledge as to what fuel is being put through the motor. either does the o2 sensor.
If you were to create a test cell where you burned 5 different types of fuel, and measured that cell with an o2 sensor, at the same mass flow you would see different voltages returned by the sensor. but if you flowed proper amounts of fuel to reach stoich in the cell, the o2 sensor would return the same voltage for each fuel.

This car has not melted down or had any issues due to e85, still running strong and I am installing an ld9 harness to run speed density tuning now. Time for more boost last synonym session netted 414whp on this exact dyno on 21psi.

Quoting myself because I can't edit. It was supposed to say last tuning* session not synonym.
The issue with summer/winter blend only comes into play when beating on the car and you really shouldn't be beating on the car during the winter anyway. Also if your car is tuned to summer blend and you drive year round then you will notice the car run slightly richer when on winter blend e85. I drove this car yesterday, it's tuned for summer blend and we just put some current e85 in it and it still runs normal. Now I don't plan on going out and racing it anytime soon but the car still runs and drives as it should.
