You will se a 150 whp Xd (NA) in the very near future and without any tuning. I think once we add the long-tube header, the Xd should reach 150 wheel hp with the intake, CAI and free-flwoing exhaust. If not, we will make an underdrivecrank pulley to help us get their-stay tuned-should be done by end of Nov. Then I am adding nitrous and going to the track! Will run over 200 whp with nitrous.

There is something that still doesn't add up for me. There are other companies that offer this kind of services for other cars like the turbo Volkswagen's, Audi's, or the Dastek Unichip for a lot other models.
Those companies in order to offer custom tunes based on the mods you have on your car, actually need a car and all the most popular bolt on mods and combinations so they can set the all the different tunes for any given mod you have.
In other words, how can they offer a re-flash for a Scion xD equipped let's say with a CAI, Intake Manifold and a custom exhaust.... unless they already had and actual xD
with all those mods to make the new base tune???
Can some one enlighten me!
I will be really interested on a tune to make the most out of all the bolt ons.
I have a hefty goal... before pursuing any kind of forced induction... I would like a 150whp NA 2ZR-FE and I believe that it will be really hard to get there with out some sort of tuning.

Just make sure to take a lot of videos when you do that!!!
NST has a 10% underdrive pulley on development right now. Hopefully it will be out by the time your Manifold is out. All my $$ is saved for those 2 parts !
Remove some weight out of the car and 200whp will be good for high 13's on this car.
0-60.... 6 sec
Remember my words!

I planon stripping what I can out of the car and running some sticky rubber up front with elevated tire pressures out back. Not going to go crazy on the suspension mods for the run, but will try 50 hp shot and then possibly a 75-hp shot with race fuel. Any info on ETs and trap speeds for Xds running at drag strip?

I have not seen any info posted anywhere yet.
One dude in Puerto Rico was making some crazy times on a xD... But that was with 12 psi of boost. Around 245 Whp if I remember correctly.
Only for reference this is my best run with the Yaris TS
1/4mile 15.85 Sec
Et 84 Mph
0-60 7.5Sec Measured with a G-tech
Those times were achieved with a stock engine (Only a short ram Intake) and with the back seats and spare tire removed.
I also had to disable the Trac Control and VSC for that run as those were killing my take offs.
Probably around 2350lbs weight
Also the gear ratios on my car are shorter than the US spec trany for the xD.
The US trans for the xD and the Yaris is the C50, a more highway oriented unit.
My car comes with the C56 same as the US MR Spyder.
I need to shift to 3rd gear to hit the 60 mph

Well to stay on topic will the jet chip topic, I just recieved an email saying that a reflash is $399. You must pull the ecu yourself as they do not work on cars. They said they would need it for about two hours to do the flash. I set another email asking the details of the flash like whether or not it would solve the issue of tuning at partial throttle due to our closed loop system. It still just sounds to good to be true since its been since 2004 that we as scion owners have had no real tuning options other the a standalone. I'm hopeing this is the real deal as NA tuning without being able to tune at partial throttle is just stupid. I think thats why everyone goes FI.

Here is the prblem with a simple reflash (if it even is possible on the Toyota ECU). The reflash willprovide changes in WOT (air/fuel and timing), but these changes will be a fixed change based (usually) on a stock motor. There is no tuning fo rspecific applications and/or cams. ported head etc... We get the tune that they have-hopefully it will add power.

I understand and have the same concern as you. This, I think, is just intended for people that want i/h/ep and no further. Major engine mods need actual time to be tuned correctly. If they have found a way to flash the ecu this should open the doors of partial throttle tuning for us though. Whether they go through with it or not, I'd bet there are shops that can tune using thier software allowing other people with more extreme mods to take advantage of full powerband ecu remapping. I'm still waiting to have them get back to me. Everything I'm saying is just wishful thinking, this flash/programmer could just be BS for all I know.

I asked around a little bit more about this re-flashing thing on a Toyota ECU.
I was told is that the the method used by JET to re-flash a Toyota ECU requires the replacement of the main chip, EPROM or what ever is called.
In other words there is no crack to the ECU. So they will have to remove the EPROM/Chip and replace it with one of their own.
On this ECU it seems like that replacement is an extremly delicate proces that is not done manually. Something like robotic welding is required.
Any ways, I agree with Richard in regards to the very little customization that a re-flash allows, but it sure would be a great option for a lot of people that won't go any further than the I/H/E combo.
$399 is not bad at all if they actually manage to obtain good results.
JET is a reputable company, I would expect them to re-found you if you are not satisfy with their re-flash results.
I say some one needs tobe a pioneer send them an ECU and report the result back to us!
I just look at JET site and it looks like they also offer custom tunning if you take your car to their facility.

Well that would be pretty cool to have done. I will deffinatly consider doing this. My only concern is not having the car dyno'd for the maps to be written too. I wonder if thier custom tuning would involve dynoing? It'd be nice to have this w while I only wil have simple addons like i/h/e but if i go turbo down the road it'd e nice to have the option of bringing it by to have it tuned for the boost.
