Ecu performance tune?

![Default](/forum/images/icons/icon1.gif)
Has any one had this done. Ive seen a lot of advertising for this method both in the UK and in the USA, Where u ship them your unit and they remap it. Suppose to be good for 20 to 35 add horsepower ,,, They adjust timeing , fuel curves to un detune what our goverment gives them to sell them in the USA. If you have had one done please let me know if it works. Cost betweem 500 and 1000 depending who u trust to actually
perform the work....
perform the work....

I've had a chat with somebody who makes custom softwareupdates, he told me standard chiptuning won't do much on our cars, the combination of better air intake, boosted charger and sportexhaust will do fine and then do a custom softwaretune on a dyno, costs me 500 euro for the softwaretune but I'm going to twinscrew my kitty first

I am aware of three tuners that provide this service.
Eurotek Designs: :: Eurotek ::
ECU Tuning Group: ECU Tuning Group | ECU Performance Chip Tuning
Paramount Performance: Paramount Performance Ltd - Engine tuning, Chip tuning, Diesel tuning
I think Jgaxkr, (or is it Jagxkr?) has done this. He has tremendous experience in doing almost every performance upgrade over a period of years. I believe his final performance package includes Avos' twin screw kit, and included an ECU tune from
Eurotek. Sorry, if I'm not quite right on this info.
His is easily the fastest XKR in the U.S.

I spoke to the owner about our xk8s with the 4.0 motor and he told me that with air filter and different exhaust with his ecu tune up that the least horsepower increase i could expect was some where between 20 and 35 horsepower,,,,,,, depending on the mileage and condition of my motor, Well being an old drag racer i asked what exactly would they do to the ecu and he said timing and fuel increases plus other tweaks.... 395 plus shipping not bad for 20 horsees,,,,, u have a choice of where the horsepower kicks in low to mid range is what i want, my gas mileage is good so i want a little more power in my cat........ And no i dont want to buy an xkr , i just want to have a little more fun in the cat I already have.

It is going to be really difficult, and expensive to get any significant hp boost in a car that has a basically high performance engine to start with.
Back in those old drag racing days, the American car engines were so under engineered out of the factory that you could put some headers, a better carburetor, a high rise intake manifold on them and get dramatic improvements with what were called "bolt on improvements". Then, you could go with a cam and on and on and end up with nearly twice the hp if you knew what you were doing.
You are just not going to get a significant hp boost on these engines in any simple way.
I wouldn't do it, and I have not really heard much about it, but I wonder how these engines would react to nitrous? Surely, if you went crazy with it, you'd probably blow out the transmission as well.

I guess it just becomes a question of who can u trust to be telling the truth about tuning these cars. If this ecu can give me a few degrees of timing and a little more fuel then a few more horses will appear. That much i know from experience, so i will give it a try and let you guys know what happens.

Not nearly as easy these days with more precision and already high-tuned and computer controlled engines.

I am no expert, by any means, but I would not expect more than a tenth or two improvement in 0-60 with just a ECU and even the minor mods that you have already done. I think that a half a second improvement would definitely be noticeable. If you can get that, then it might be worth the money to some guys on here. As for me, I don't use the capability that it currently has (I don't go around flooring it all of the time, or racing with people) but I'd be interested to see what results you can get. Thanks.

Bought the ecu and installed it ..... Went on test drive ,,,,,,, techs say shift it and use all gears, run it hard to let the computer and trans get to know what levels have been increased in ecu..... I was to drive it between 100 and 200 miles. Keeping the car in sport mode 4th gear . Well at 70mph in floored my cat and it jumped to 135mph really quick, Could feel the extra power. The car was very responsive and sounded great. Techs said it would run even better once i got the 200 miles on it.
Well on the way back from my test drive i decided to floor it again at 70 mph and the engine rev went into the red line.. Transmission started slipping. Well long story short I helped an already weak transmission get worse and finally just go into limp mode......... Well i didnt get to see what the new ecu will do on the low end but im impress with the top end.....Getting all the updates put into my new rebuilt tranny ,such as the drum and the valve body. Will test soon and let u guys know what the low to mid range feels like........ but so far so good ..EUROTEK DESIGNS seems to be very honest and thier product seems to work....total cost plus shipping 525.00 . They got the ecu on tuesday an i had it back wednesday........Cant beat that

"We can only tune the XKR from 2006 onwards, there isn't a tool out there that can communicate with the older Jaguar's."
Then I asked him about Eurotek and Eurotoys. He replied:
"They use a tool called Dimsport. I know the guy who made that tool and that tool doesn't support your car. I just checked my Dimsport just to confirm. I've been in this industry for 24 years. I know who is using which tool, etc. Paramount used to have the ability but their tuner who had a tool that actually worked left about 4 or 5 years ago."
__________________________________________________ __________
I also spoke to someone at Eurotek Designs, whom stated:
"You MUST tune the ECU with any pulley upgrade otherwise you will easily detonate and trash the engine. Anyone who knows cars and forced induction knows a tune is mandatory especially when going from 11 psi to 19 or greater as the Stage 2 pulley offers. We do the programming for the diff conversions and are the only ones who can do this and the ECU units."
I agree with Eurotek and ECU tuning makes sense to me. I've done this several times in the past with my project car (also supercharged). So it it true that there is no tool available for pre-06 Jags? Which story is factual...and who is misinformed?
At this point my brain is muddled......

You could try giving Eurocharged a call.
There is a thread where a member with a 4.2 STR got his tuned.
https://www.jaguarforums.com/forum/s...on-str-104033/
I believe the STR is a slightly different ECU, but it's worth a call at least.

$800 eurotoys not eurotek,bench programmed to your liking. Really good if you add another type of blower, or something radical, in MY OPINION.
Our computers are great at self tuning with the lower OR upper pulley, no tune required,just a hard reset.
Your option. I have found after removing my throttle cable slack and using 93 octane and a hard reset, my ecm has this car flying !And that not an exaggeration.![Icon Naughty](https://www.jaguarforums.com/forum/images/smilies/icon_naughty.gif)
At a local dyno, a xkr had a lower and cold air intake, the ecm was dead on spot with the fuel ratio to air.
