Ok,

Am I the only guy that noticed they said they are not familiar with the common pulley mods and alcohol injection?


Seriously, would you trust anyone to tune your car that does not understand these things? If they do not understand these common things....then just ...wow..really wow...

Buyer beware.

 

Alcohol injection? What's that?

 

search under alcohol injection.

Common, even on this board.

Inject a mixture (usually 51% water 49" methanol) and increase your "octane" from say 91 pump gas to 113+, while cooling the intake air temp 50-70 degrees f, allowing you to run more timing advance and make more power by reducing detonation.

 

Leave it all alone and pop on AVOS's 200 chp twin screw.

 

Have you done this yet? What did it end up costing in total?

I'll admit, so far AVOS's TS is the only "Proven" big HP bolt on. Everything else has only been unsubstantiated rumor.

My goal is to add approx 100 RWHP with my mods. I hope to post my actual results (dyno) in approx 2-3 weeks.

 

I wish AVOS made one for the STR.....

 

Anything you can do for those of us who own a non-supercharged Jag, like my normally aspirated 4.2 liter XK Coupe?

 

Seems strange considering they offer the pulley upgrade for Jags on their site. They also have no dynos to back up their claims for our cars. They also don't seem interested in doing business here as they won't answer any specific questions about how their chips "work" other than making them a lot of money. Sound like another snake oil tuner, only at 20 times the cost!

 

Very common in the Mod room. LOL

+1, I wish we could see some posted concrete results from the supplier and a contact name rather than Sales@ in any posts.

 

So nobody knows what cable and software or type of system these "tuners" use? If that could be discovered/released affordable tuning with real results might not be so out of the question.

 

Has anyone had any successfull tuning on a non-supercharged model xj8 or xj8l 2006? Thanks... I like the idea of the switch on a module to make it stock, and to not need dealer reflashing ever. Is this possible on the 2006 xj8 and xj8l? Thanks.

 

I received a dyno result from a Jaguar specialist that can only be described as a joke. Posted below. Do you believe these guys can actually outperform oem engrs without any side effects? I noticed that your request for empirical data went unanswered.

 

queenie ,are you sure you are not related to JagV8 on this forum?

seems a lot like his remarks.

 

Hi, any way to easy remove 250km/h max speed limit on XF SV8?

 

What can ECU do with 2011 Jaguar XJ Super Sport 510hp as to boosting HP ?
What is the shop address near Washington DC ?
I am north of DC about an hour away.

Thank you

 

deleted duplicate post sorry

 

This week my tune was busted. With that said, I am going back to the tune because I refuse at this point in life, to allow a manufacture to tell me how do "own" my car. My 2013 XFR was in for a guaqge pack replacement under warranty. While I have to believe what happened was a tech error which I was forced to eat, it happened never-the-less. The dealer claims that when they hook up to the OB2 plug, JLRNA's system uploads,downloads what ever the status of the car it reads. They claim that because conflicting software was detected(not the tune the factory expected to see) my ecu refused to receive any new programming from the factory.

The result was that my car sat unable to start in the dealership for five days. Many heated conversations occurred between myself and the dealership of which i have bought over 20 new LR and Jags since 2001. I suppose I was the heated one, they were very calm. ON day five, a Jag regional tech arrived to declare my ecu dead and not able to receive my new gauge pack programming much less start the car. He claims that due to conflicting software, the ecu went to lock down mode(anti-theft)> Most likely due to the tech continuing to send and resend reprogram commands, the ecu assumed someone was trying to hack the ecu.

Bingo, i had to spend 1200.00 for a new ecu and warranty was refused. I am by no means done. I am convinced there was incompetentence in how the techs handled my situation. In this world of technology, I will not accept that the ecu could not be set back to a virgin mode and thus completely re-programmed.

My warning is that any ecu logs programing changes and thus programs are detectable. I do not believe that simply hooking up the factory OB2 connector will throw an ecu into orbit. I think the tech in haste tried to errantly force fed my ecu until it fought back. Because the guage pack and keys all have to be reprogrammed at the same time, there were too many variables involved. Likely a short cut was tried and I became the victim of the program.

I of course retained my old ecu. i am in search of a person that that can resurrect my old ecu at which time i would like to have it installed back in my car to put this back on JLRNA for being unable to free up my ecu. Any and all recommendations are invited. You do not need to dump on me( I got what i asked for), my dealer for not standing by me(they did error likely in covering their techs butt), or JRLRNA for now. I just want to forensically figure out what really did happen. I am a student of life and I will learn from this experience. Maybe that i am wrong and this tune really did do the damage or that my dealership needs more training.

Thanks

 

What happened to you is what everyone fears when entering a cars
computer.
The very reason I have held back.
As stated, I have 2011 XJ SS. The car runs excellent and will not take a chance
of $%^ it up. @ 35,000 miles its just braking in and I am getting use to high way performance ( sports mode). Not treating it like a baby and using it for what it was made for, like having a car within a car. Its amazing how upset some BMW drivers become when they get passed.
I just paid for my Extended Warranty $3000 to 2021 ( About that ) and sure don't want to lose that, and at my age I should slow down.

Its a shame--- Jaguar has not realized the large market out there
for performance. They are doing there best in keeping maintenance reports low so sales stay high. Opening a 'Sped Shop' would help their income a good deal.

~BEST~
