I’m just trying to find a tuner that will tune for e85, Currently talking To Viezu, to see what they have.
Hey guys just a little info regarding tuning that you may or may not he aware of. 1st off, these companies that sell us their pullies, and tunes etc, are selling you what is referred to as a "canned" tune. Meaning it's a predetermined tune with parameters that are set on a test car and then mass sold for the platform. There is no data logging or a tuner physically looking at your cars info at all. Which is why canned tunes are frowned upon because no 2 cars tune the same, waaaaay to many variables to take into account from motor health, mileage, normal wear, temperature, elevation, humidity, etc etc can all DRASTICALLY change one tune from another. To combat this these companies typically make their canned tunes waaaaay over "safe" for lack of better words. So even if someone from a mountain top of Colorado in 20° weather buys the same tune as the guy in Las Vegas Nevada, theyll both be overly safe, overly rich, and honestly not utilizing anywhere near the possibilities of your car. Thus in my opinion its a waste of money... now with that being said, a real tune will have a tuner whether on his own or through a performance shop will do "pulls" aka wide open throttle logs multiple times either on the street or on a dyno and will make numerous adjustments based on YOUR car specifically. This is the safest, most accurate, and best performance way of getting your car tuned and typically it's about the same price... AND any tuner will tune for E85, it's the most common fuel type used by car enthusiasts and any knowledgeable tuner should know their way around it real quick. The only question would be, is if they've never tuned a F type before, theyll need to make sure the fuel capacity is there in order to run E85. This can be seen by viewing the injectory duty cycle on pump gas at wide open throttle with whatever mods you want installed and then calculate for the 30% increase needed to run E85, if theres room to do so and keep the duty cycle under 100% go for it! It's cheap race gas! If not tons of people settle for a half and half mixture what is referred to as E40 - E47 etc. And just a tip, find a tuner you trust, someone that has a proven track record. There are lots of posers out there looking to just take your money. Reputable shops are the best bet and IMO hptuners is the best software available hands down. Just keep in mind our cars take a crazy number of credits to unlock (8) most cars take 1-4 and its $100 per credit plus the tuners fee. So expect around $1000 - $1200 and tack on a lil extra if you want to utilize a dyno. Hope this helps someone
There are only a handful of tuners that know which of the hundreds of tables to hack in the AJ126 & 133 maps.
VAP may send you a tune out of the box, but will work with you based on data taken from dyno pulls, data logging and driver observations to customize their tune for your vehicle. A good local tuner will tell you they are not familiar enough with the F-Type to tune them.

That's why I am going with hp tuners for a custom tune to get away from the canned tuned. Gonna throw in a larger fuel pump as well. A canned tune is an overly safe tune meant for different cars at different elevations etc. So you leave alot on the table with those tunes. A custom tune is a tune meant and made for your car and is soooooo much better in everyway.
E85 is readily available almost everywhere here in Texas at the pump.
There are at least a dozen stations within ten miles of me that offer it. Maybe it's a regional matter. There are also a few stations that offer non-ethanol premium. I've never tried either alternative, but then I'm in the base model where they may not make a difference.

”Canned Tunes” are typically safe tunes, because they are developed just like OEM tunes as a one size fits all... you’re 100% right there. But custom tunes aren’t some magic sauce that will gift you huge horsepower gains. Maybe you’ll get an extra 3-5% over what you would with an off-the-shelf map, but no tuner in his right mind is going to max out your car specifically for your climate/elevation/etc. How pissed would you be if you took it to Colorado and blew the thing up because some tuner optimized your tune for Arizona? The software has internal failsafes for that anyways only an idiot would touch. You’re really making a much bigger deal about this than is necessary. Off-the-shelf tunes are fine when you get them from a brand leader like VelocityAP or similar. The minor gains of a custom tune aren’t worth the additional risk and cost unless you’re racing.
There are at least a dozen stations within ten miles of me that offer it. Maybe it's a regional matter.
Definitely a regional matter. Some places E85 is sparse and can impose range anxiety similar to driving an EV. A lot of people don’t want to plan fuel stops in advance or go way out of the way for E85, despite its performance benefits.
Maybe this should be confirmed by Vbox / drag strip ticket.
Everything should be confirmed like this.
Maybe i've missed it but are there any 1/4 mile results from a V8, same track, stock vs. tune & pulley? without any other adders like water/meth, drag radials, etc?
And I find it puzzling that aside from Philly Single with the nitrous, water/meth, drag radials, etc the highest trapping (i.e. most hp) V8 F-Type on the list has literally just a tune and cats, stock pulleys, stock everything else.

See my sig. Same track, same general weather conditions. Stock vs. VAP lower pulley and OTS Tune. Next spring we’ll add race gas tune to the list. Time slip is post 156 of my F Type thread.

You couldn't be more right. However, developing a custom tune requires datalogging the correct PIDs and 100% of all devices including the dealer SDD scan tool will NOT log values correctly. If you used a generic tool or even HPT for JLR 3.0/5.0 Bosch, PID's not present in generic protocol are; absolute pre charger, absolute post charger (there's a MAP value but incorrect on generic PID), target ignition, knock retard * per cyl, charge temp vs pre charged temp vs post intercooler temp, SC internal bypass, LPFP HPFY Injector duty. If you had an Autel Maxisys Elite or even the dealers SDD, you would not be able to log correct values for SC internal bypass nor MAP pre charger in kpa. If the dealer SDD can not log all important values correctly, how is the tuner going to create something that will nearly max power AND claim the file is reliable and safe?
"If no tool is available to log these PID's, how is VelocityAP doing it?'..Well, very simple, I never said such tool doesn't exist, I have my own that I research and logged the hex addresses of each requested PID. So, yes I can log these values with our own custom created datalogging tool.
To use HPT for custom tuning. The device is $300 + 8 credits @$50/each = $700USD for just the device and no file what-so-ever. Add on a dyno hookup fee and day rental for $1000/day + your tuners custom labor time 120/hr x 8 hours = 700 + 1000 + 960 = $2660USD for this custom tune done on dyno. Now dyno is useless to chase high numbers and drag and circuit track testing would be required to claim any chance of reliability, so lets add in 4 more hours of tuner labor for edits and research = 480USD + 2660USD = $3140USD (all built from scratch). The smack in the face will be when the tuner realizes the HPT maps don't have all that's needed to developed a dual pulley file for a 3.0/5.0 Bosch ecu. So, either the tuner does additional research to chase these maps and buy a mappack for WinOLS OR hopes HPT will add them OR he/she lies and tells you all is GOLDEN!!(and that's all assuming they logged and received the correct data from PIDs) So for $3140USD you can officially say you've got a custom Stg1 tune with no pulley edits (unless a mappack for WinOLS was purchased and extra time invested, then add extra labor/fees to $3140). I find this would be a hard pill to swallow for 99% of JLR 3.0/5.0 owners...LOL then you need to hope and pray you made a wack load more power than the off-the-shelve files done by a JLR reputable tuners.
The German, Jap, American brands are well established into the tuning world. There's many reasonable cost tuning devices and even simple android/ios apps that can log all sensors correctly for under $20. Getting a custom tune for those cars isn't really any cheaper if all above is performed and no solids or favors are given. The only benefit on those brands is when creating higher power numbers, the correct data can be viewed without the need of custom created datalogger tools. The British brands like Aston Martin, Land Rover, Jaguar, McLaren..etc all use similar ECU's and NO device is sold on the market that can load up and view all the desired PID values...making it almost impossible to claim a tuners custom edit is maxing out power reliably.
Anyone can refuse to like my reply, but it's blunt and to the truth about a full fledged custom tune. Custom tuning as your explaining is well off from the claimed $1000-1200 plus little extras. Custom tuning is really pointless until you've maxed out all remote tuning options and need to dial your car in on a circuit and/or drag. Dyno tuning is only valuable if you don't have anything created or you want to try and address a glitch in a controlled environment. You'll never be able to tune for max power in a dyno room unless you had some sort of high end wind tunnel to simulate the road speed air ramming on the front heat exchangers and intake inlet. Nonetheless, if you source a tuner for a custom tune, please make sure they have a solid background in this similar ecu and engine platform. *Any Tuner Can be an Expert of All But a Master of None!* This is the main reason VelocityAP has developed products for the British brands and not dove into the VAG or similar markets. We do tackle other brands, but when it comes to the British brands, that's where we excel and push the boundary.
As for my experience with ONLY the MED17.8.3 ecu language that I build our "box tunes" from, here's a screen capture from today showing VIN's tuned..(bear in mind, not including multiple files per VIN and each VIN having more than 60 maps edited in file). Those 622 VIN's average 2-5 edits per submission, putting that number over an easy 1,000 tuned files for JLR Bosch MED17.8.3. I'd be gun shy to spend $3140 on a custom tune hoping that tuner knows what he/she claims versus a box tune from a company with over 1,000 files on your same vehicle model with good feedback for a price of $995USD(and still have the option for custom edits in that price and custom tuning if labor is scheduled/booked)? Seems like a no-brainer ..just my 2cents

I can't argue with you on whether or not hptuners has the required stuff to tune jag/landrover products, as I'm not a tuner. I'm not sure why the vehicles would be listed as compatible if they weren't 🤷♂️. I for one am copying this reply and questioning hptuners personally as if its true, that seems like a scam, and they have a massive following around the globe. What's the point in having a tuning software if you can't access the needed information to properly tune a vehicle. However I will disagree with you one 1 thing. You obviously work for velocity, and I am by no means questioning your guys quality, effort, etc. But just being a big company doesnt mean perfection by any means. Zzperformance, a well known company the supports the ecotec platform sold me a "canned" tune when I was an inexperienced teenager and it melted my piston rings. My now current tuner, looked over their tune and it was running incredibly rich in low rpms, and lean in upper. Roasted the motor. Now, wiser from the experience I equip a wideband along with monitoring other things in any vehicle I modify at all. AND our ecotec platform has countless proven results of actual data logged tunes vs companies canned tunes gaining large results virtually every time whether the canned tune is from one aftermarket company or another. And the company's seem to follow a trend, trifecta tunes are always rich as hell and timing not advanced hardly at all. Again, I'm aware I cannot use this as an example to claim all companies are like this and I don't doubt you guys have put in extensive testing especially considering Jaguars are a wee bit more valuable than a cobalt 😂 but just in my experience, A good tuner with data logs trumps a predetermined canned tune every time. And I agree about the dyno. All of my tunes are data logged from numerous street pulls. Dynos are for bragging on social media 😂
Oh and you pay waaay more for dyno time than I've seen anyone pay, course I'm in podunk oklahoma lol. But even in texas with their huge underground racing following. You can get dyno time cheap as hell.
Please don't take this the wrong way, but are you ok with that?
Because, for me at least, those numbers don't add up when this is meant to be from stock 542hp to tune & pulley 640hp
Not sure how race fuel would help, because those numbers look like the current tune is not pushing any boundaries at all.
Haha I mean... I’d love to break 10s on this set-up, but I don’t believe my car is making 640. Running the numbers through a 1/4 mile calculator, 0.4 seconds at that et is equal to 55hp. That sounds about right to me. My car is also pretty weak from a mph standpoint, making me think my car was on the lower end of the horsepower scale from the factory. Who knows.
I have a map specifically for race gas that will he used. Should provide a little power bump.
Does anyone know if there are aftermarket injectors available? Or if the stock system is capable of running straight e85 with dual pulley upgrades? I know JLR pushed these things to around 800hp in testing so the factory fuel system obviously has some wiggle room, but how much lol. Also love you use of the Audi heat exchanger, I'm totally stealing that idea. I live in Oklahoma so I feel some of your texas heat lol.
The high pressure side should run full e85 fine. I am currently looking in to modding the low pressure fuel pump. Probably going to use a Walbro 470 pump.

I already have a walbro 450 otw.

And from my experience, I have NEVER seen a canned tune out perform a custom tune. The only way a custom tune won't be worth it, is if the tuner you chose is complete garbage and is a utter joke. Getting the right tuner is the key.
And not that I am discrediting you, but I've never known hp tuners to not be good.
