E85 Power Increase

SierraHD17 · January 11, 2019

A throttle body is a butterfly valve and anything past 70% open is the same flow rate as wide open. The trucks are not limited from wide open throttle tuning in the stock form.

Route 17 Southfields NY between Tuxedo and Harriman the Valero gas station. Right by the old Red Apple rest.

What's the price for it. 1.69 on the island

E85 went up a little for me. Was at $.99 a gallon and went up to $1.12. But then, regular went from $1.80 up to $1.92. it does help that I live in ethanol central and I am surrounded by 46 ethanol plants.

Down to $1.799 here.

at 1.99 for e85 and gas being 2.15 per gallon, e85 is not going to cut it unfortunately...

perhaps if I had the 5.3 that saw some noticeable power as a result of using it I'd give it a try, but from what I've been reading, the 6.0 does not respond to e85 even remotely as close as the 5.3 does.

According to GM, the 6.0L sees no gain from running E85.

Probably because it would exceed the horsepower and or torque rating of the transmission. A good tuner can fix that!

Its the same ignorant little supported ecm in these trucks since 2011. So far one guy has done a blower and so far it works... let him run it for a while and see lol. The ecm in the gas HDs is a pretty useless pos. Feel free to mod and tune as you see fit however don't be surprised when things don't go exactly as planned.

You can tune it but to what extent is what I find troubling. Tables are either missing or flat out don't work. Take something as simple as idle speed. I remapped my table so the truck would not rev stupid high on a cold start. Did the same changes to my employees 2014 1/2 tons e92 ecm, wrote it and it works as expected. Rewrite my e78 in my 17HD and it literally does exactly what it did stock.. totally ignoring any values I changed in my new file. I have ghost knock off a wide open throttle start... it's not burst knock as its gone as is anything else that pulls timing on throttle transition. It's not real as it's a static value being pulled no matter how low I set the timing those cells.. myself and multiple other tuners can't explain it... but I have a good idea why.

See the e78 is only used in gas Hd trucks and then like Chevy Cruzes. It's not the same OS as a e92 and go on HP or EFIlive and you see there is dick all for support for it because honestly nobody cares lol. The e92 has like hundreds of pages of questions on Hps forum but the e78 that has had a section since 2011 has maybe 10 pages of questions... in 8 years lol. How much effort do you think they will put towards an ecm nobody gives a damn about.

My truck runs way better tuned than stock so if you want to tune it go ahead and do it. If you think waiting will do anything you are wasting your time. What support they have now is what you are getting... it's only been around for 8 years already lol. I totally expect the 2020 will have a new ecm like the 19 half tons so this is the end of line for the e78...

I would not bother wasting money on a blower on one of these. It's not going to be fast in any way shape or form and just get stupid hot loaded. Do a set of gears and let it eat... But it's your money.
