So I am running a e40 tune by VAP. I am full bolt ons, with an extra heat exchanger and larger pump. This car is a freaking rocket. I am running a little over 10 more degrees of timing compared to my 93 tune. Chris has done an amazing job with this tune. Car pulls so smooth and strong on e40. I added the ethanol sensor so i can know my exact E content. The car ran a 6.77 60-130 on the 93 tune. And it's much faster now. I haven't had a chance to test it again. When I tried the satellite were low. And I returned to work before they got better.

 

So is the car aware of the Ethanol content or just you with a readout? E85 is pump gas here in the Midwest and our local station is always E80+ when tested.

What's your current pump/injector duty cycle?

I am on the fence on Meth or E85 tune, last I talked to VAP they said it was specialty fuel, like race gas, but I am not sure they were aware it was pump gas for us.

 

Was your car Flex-Fuel stock? Do you have the yellow gas cap with the E85 info on it?
We have found the Flex-Fuel sensor which you show in your pictures but we have not found out if Jaguar did anything else?
Like BigStickers says does it require any other changes? Injectors and such?

Are your HPFP's adequate to pump the extra volume or do we need to upgrade the fuel pumps?
I ask because this is beyond common in the Taurus SHO forums BUT those cars have all kinds of Alcohol tunes and even then when running E30 the stock pumps can't keep up.

I'd also like to add that in my conversation with Chris at VAP, this is possible for others as well, however it would be required to have the same setup that Terrance has with the ethanol reader. Kudos to Terrance for going so down the rabbit hole on this one. I like it when someone can post what they actually did, with actual part lists, actual pictures, with verified time slips and has the step-by-step guidance to replicate for others to attempt to do the same.

 

The ethanol sensor I added is just for me to know the exact content. It is not tied into the CAN system. The tune is setup for e40. So I want to make sure I have e40 in the tank. It's only a beta tune right now, but its amazing. Chris says the logs look great, so i leave it to the tuner for that.

 

No my car is not flex fuel stock. The hpfp and injectors are fine and can handle the e40 great. The lpfp is the weak link and why the system can only handle e40.

 

Very interesting! Have spoken to Chris @Velocity about E20-40 and I’m thinking about doing this as well!
thank you for the feedback!

 

Yes thank you for any and all details. Yours is the first non-factory flex fuel sensor I have seen. So glad it's working for you too! We have several factory E85 cars that have posted to the forum but they are really rare and we don't know how or why Jaguar produced them either? Did that option even show up on the window sticker?

If anybody is interested these sensors are all over EBay for reasonable prices. Part #CPLA-9C086-AA is even available new on Amazon for around $45.

Is your car still running okay? Years ago there was chatter that (non flex fuel) vehicles were not equipped to handle over like e10 - e15

 

Yup still running strong as ever.

 

Any dyno or updated stats?

 

I have some experience using ethanol vs pump gas, but not on an F-Type; it was in a one-off mid-engine turbo Honda car. Anyway (for a turbo engine), expect much worse fuel mileage, like 20-30%. Also, while ethanol is cheaper than gas, you have to weigh that against the actual cost per mile (yes, I realize that fuel cost isn't the primary reason for using it). A possibly bigger issue is if the car is ever driven somewhere that doesn't offer ethanol in the concentration the tune is set up for. What if they have E85, or E10, but not E40, what's the fall back plan?
My car doesn't have an issue because it uses a GM ethanol sensor and the AEM Infinity ECU seamlessly makes adjustments to suit. In SoCal at least, I would Not use a tune that locks me into a particular ethanol concentration because sometimes the stations that carry it are few and far between. I very much understand why VAP has not offered a flex-fuel setup (yet?) because it's much more invasive and expensive.

 

I did a dragy of 10.93@131mph. But it was unverified. I travel for work, so I don't have alot of time to do stuff.

 

I have ethanol stations everywhere here. Also I take my tuning module with me everywhere, it stays in my glove box. I have my e40 and 93 tune on it. So if I want I can flash back to 93 in a couple mins.

 

what's your 1/4 time? I bet it's a solid low 10s? 6.7 is crazy fast my jaguar xf ran 7.89 60-130 and 1/4 11.1 at 128mph can't imagine how your car feels I want to try again the 60-130 is just too hot here in cali still on 91 octain and upper pulley only

 

Yeah I got 1 dragy run in and it ran a 10.93@131mph. But the road had a slight slope downward in it I guess so it was unverified. I haven't had a chance to rerun, since I'm always away at work plus it's been 100+ lately for weeks here in Texas. I had a race with a friend of mines that has a atsv and he dynoed 630whp. And I am dead even with him, with a very very slow pull on top end.
