Tuning an ECU of an unmodified XR6T

Hi Guys,

I have a completely standard XR6T. The fuel economy is 19litres/100km and when I fill up the display says 410km to empty. The car does not have as much get up and go as i would expect. The only thing I have to judge this on is being beaten off the line and to 100km/hr by a V8 VT Commodore on Monday night. The V8 was pulling away from me up until we stopped. (I have read a lot of discussion on the fuel economy issues on this forum, this isn't my motivation for this post).

I have read a number of articles on this forum regarding the engines not being tuned and mostly running rich. I just have a few questions regarding this and they are as follows.

1. Will the engine running rich cause dodgy fuel economy and sluggish acceleration?

2. Is it worth getting a standard xr6t tuned properly?

3. Has anyone done this?

3. Are there people in Sydney that can do this sort of thing that anyone would reccomend?

4. I had a flash upgrade done today during the 15000km service to stop the car stalling (or almost stalling) when you pull up at stop signs etc. Does tuning the ECU erase this upgrade?

5. Will tuning improve the acceleration?

6. Does anyone have an approximate cost?

If anyone has the time to answer I'd love to see what you have to say.

Thanks again,
Steve

Re: Tuning an ECU of an unmodified XR6T

The XR6 turbo has to be one of the most supported ford products for after market tuning available. As far as i can tell you'll see massive improvements with as little as $1000 expendature. Your power will jump from around 240fwkw to around 300fwkw, economy (cruising) will be far better, responsiveness will be much improved.
If memory serves me well some xr6t's run around 4psi and some (earlier) 6psi. The xr6t I test drove was a bullet. it was well and truly run in and had around 20,000km on the clock. No v8 commonwhore would have beaten that puppy with out some gen 3 mods backing it up.

Check out the many, many threads in the forum on this vehicle and you'll soon understand why i am one very envious Au v8 owner that is struggling to keep up! You have a great vehicle that can smash most if not all that holden and hsv has to offer if given only the slightest push.

Re: Tuning an ECU of an unmodified XR6T

I hope it was a VTII with a gen3 5.7L V8 or your car is stuffed.

Anyway good news is for $1500 there are a myriad of tuning options for the ecu which will bring huge gains in performance and reasonable gains in economy.

Re: Tuning an ECU of an unmodified XR6T

Yeah guys, thanks for the replies.

I was initially looking to get it tuned without getting the chip upgrade and voiding the warranty. Although, now I am sort of waivering toward the Unichip Phase I option.

Does anyone know if there are any good places in Sydney that will tune a standard xr6t, and how many problems do ford give you after this has happened.

Re: Tuning an ECU of an unmodified XR6T

I guess Peter can elaborate further but you could have the best of both worlds with a tuned Unichip, more power plus better fuel economy as the fuel is leaned off. That is of course, if you can drive around without giving it too much curry with the more power!

Re: Tuning an ECU of an unmodified XR6T

IMHO there no such thing as tuning a late model car. it's an out of date term unless used by the likes of Peter where a change in the program is made. Go the unichip and you'll be very very happy.
