Could the Holley Sniper dual quad use this if not would it work with a different Holley ECM ? Also are any of your ECMs adaptable to CNG or LPG with flex fuel ?
Could you do a series on the basics? One video per icf? Would be great to show some of tips and tricks (like auto filling in table values.) Also a video on data logging and viewing the data log.
If initially using 100% gasoline (no added ethanol) and the flex fuel sensor is reading 100% ethanol, shouldn't the fuel flow multiplier be 63.2% at 100?
Ok, figured this out...I think. After some reading, I discovered that I wasn't taking into account that fuel flow is measured by mass flow rate, not volume. Since ethanol doesn't need as much air to burn (lower mass of air to mass of fuel), the AFR decreases. Basically, with more ethanol, the air-to-fuel mix drops. For example, it goes down 39% for E100, 38% for E98, 34% for E85, etc. I believe these are the Fuel Flow Multiplier percentages that are used to adjust for the extra weight of fuel needed to match the ethanol content.
It's a great video, but I think there's one pretty big error. Going from gas to E85 requires a 35% change in AIR FUEL RATIO (9.65:1 on E85 is 65% of the 14.7:1 for gas). This requires a 1.52 multiplier of the FUEL FLOW. Thus, a 35% decrease in AFR requires a 52% increase in the fuel flow. So to go from gas to E85 (assuming you had a good gas tune) you would multiply all the fuel tables (base map, cranking, AE enrichment, after start, etc) by 1.52 or as this video shows, instead use a 1D table and multiply by 52% (not the 34% shown). Since there are other factors beyond just stoich, additional tweaking is needed. But my point is the 34% Fuel Flow Multiplier shown in this otherwise great video should be 52%.
That is incorrect. I can tell you from experience that roughly 35% more fuel keeps the AFR in the same spot. Saying that because 9.65*1.52=~14.7 you need to add 52% fuel is over simplifying it, and plainly not how it works. These are two completely difference chemicals with completely different behavioral characteristics.
@@ArthurSperotto Been driving my cars on flex fuel when th Holley Dominator for 4 years. Street miles, engine dyno and chassis dyno tests. My pump E85 near me varies from E55 to 90, and the flex fuel sensor goes into the Holley fuel tables. That's my experience, on all the fuel tables (not just the base map). That is also the math. If you can explain why you're different I'd love to hear.
It cannot. you can use our resistor plug to get those alternators working correctly. www.holley.com/products/ls_power/ls_and_lt_accessory_drives/low_mount/ls_and_lt_accessory_drive_components_and_service_parts/parts/197-400
Do they have any EFI components available for a 350 Chevy what type of kids should I get
So once I install and wire up the FF sensor, setup the flex fuel sensor IFC, is that all that is needed to read ethanol Content?
What if your already running e 90 and you want to add a flex fuel so you can run e85 from the gas pump what percent would you type in
Does Terminator X have this capability? I can't find this in my Terminator software
Having trouble doing this on the v6 software. Is there an issue with it?
Keep up the great work Holley, thanks!

If I wanted to run E85 sometimes
Can I just chang my target
AFR then change it back?
Is it in by that can convert my whole car over to this digital system
Is this available for the Sniper units?
Thoughts on using a digital to analog converter to use an analog input? (Assuming you don't have a digital input available)
Ryan thank you. Can you do a video on how to set up closed loop boost control with Co2?
Thank you Ryan for the 'Go To' Video
Is the E85 to corrosive for the Holley injectors and aluminum base
You bet, that's why you put gasoline in to lower the ethanol content when you don't need it. It also likes to gel in the cold weather.
Can you set it up to display fuel temp also?

I believe they have one for data logging, look in their videos.

Can a flex fuel sensor be added to the Terminator x max?
Yes sir, it is done through the I/O ICF just like HEFI! thx J

Fuel temp also changes flow required a lot more with E85.
Good point, but wouldn't be 63% if the scale is for 100% ethanol?

I would say if your flex fuel sensor stopped at e85 it be 52% but it is scaled to 100% so it should be scaled to 63% no?
can i run e85 in my sniper xplow ?
Can the dominator control a new style 2010 and up GM alternator?
It cannot. you can use our resistor plug to get those alternators working correctly. www.holley.com/products/ls_power/ls_and_lt_accessory_drives/low_mount/ls_and_lt_accessory_drive_components_and_service_parts/parts/197-400
This was super helpful, thank you.
Glad it was helpful! Thanks for the feedback!
Thanks for the good info!
So whats up? Other sniper videos say you cant run E85 or anything over E10.
This is for our more advanced EFI users with the Dominator and HP based systems, not Sniper! Thx J
Why not support e85 on the sniper!
@@zx6rkawi09 i would like to know this as well??
thanks so much for this
Can this be used on a super sniper ?
