Sorry I did not clarify... Have you been doing E85 flex tunes yet?

I understood what you meant, Flex fuel conversion Yes.

Understand the the higher the ethanol content the more power you can make but also lowers the Power ceiling based on what the current fuel system can supply.

So there may be a small advantage when the car is stock but as you add parts you will run out of fuel supply at a lower HP than on Gasoline.

I plan on doing full catless exhaust with longtubes and ported stock intake manifold on top of my cai and PTB. May even buy a drum of e98 for another small advantage at the track. Guessing that will be ~460 rwhp range when on E through the auto. Will the fuel supply handle that?

We know the stock fuel system can handle 560 RWHP on Gasoline and it takes 30% more fuel by volume to burn 100% Ethanol which drops your RWHP numbers to around 400 Wheel.

I would expect you to reach your goal on around E-75

Wow sounds very close.

What's the first stage in extra fueling that could give me a bit more ?

Hi ted how long (miles) should i wait before mods. LT,MSD. CAI and a Tune from you on a SCT.
Thanks in advance.

Is that 560rwhp from a supercharged car?

I would focus on power upgrade parts first, Bang for the buck if you will, our 460 RWHP package for instance.

Fuel system upgrades are very expensive pump and injectors can easily exceed 4K.

There is no wait time as far as the car goes just a decision you have to make on your own terms.

Remember the amount of fuel we can burn in the combustion chamber determines HP the engine can make.

It takes 1/2 a lb. of fuel per hour to make 1 HP.

There is a slight difference in Peak HP NA VS Supercaharged due to AFR we run for each.

Let me refresh this info just a bit,

I am currently at 575 RWHP with our Fuel pump voltage booster at 10 psi boost and custom tuning.

The High fuel pressure is still holding at 2200 psi.

Howdy Ted,
What software are you all using, I assume HP Tuners. This is what I know and want to ensure that I understand the new Gen 6 ECM. The new system is TQ based so everything we learned with pre Gen 6 does not apply. The E78 and E39 ECM use a new torque based control structure that is similar to systems used by Ford and Dodge. This is a significant change in the way the ECM processes inputs, performs internal calculations and also controls the engine outputs such as throttle, spark and fuel. This leads to a more integrated and streamlined control process, however, it also means a change in thinking for many tuners.
I was the first A8 build with several mods and working with ADM to get the holy grail tune. We started out with what was known and I would say there have been at least 10 tunes on my car tweaking each one. The biggest one for me is driveabilty for any street hot rod. Being a TQ based system (right foot) have you had any issues on the low end. Seems like I get it right on the low end and not quite acceptable for high end and vice versa. Have you or any of yer customers seen this? Thanks!

Howdy,

I use SCT and HPtuners for tuning GM vehicles.

You are correct, the thought process is a little different.

I already bring a wealth of experience since I have worked with Torque based computers since 2007 in the Cobalt, Solstice, and GM 6.0 trucks since 2010, and this E-92 since 2012.

The transition for me has been pretty smooth for the most part.

We have no issues getting them to drive right.

Ted.

Ted,

What is the expected effect of altitude (5000 ft) using a RotoFab CAI and tune in a NA engine? Is the same percentage in delta gain to be expected, more or less? Does a CAI usually help more or less at altitude vs sea level?

Thanks again for your valuable contribution.

[JANNETTYRACING]

The delta power gains will be the same, regardless of altitude.

We are now tuning 2017 models with HPtuners 3.4
