Where are all the buyers for this high demand product?

Perhaps you should take up Zoasis's offer to give you a ride so you can feel it in person, or you could just look at the dyno.

DETONATION

But so far, I'm very satisfied with it.

I have been following the ECU thread for some time. Can you please clarify about the pinging / detonation.
With the TECHNOSQUARE ECU flash the computer should learn and modify the short and long term fuel maps to maintain the 12.5:1 air /fuel ratio that was programmed in correct?
Thus, if you put on say a Crawford intake and Borla catback exhaust -- the air / fuel ratio may TEMPORARILY become too lean, but after say a day or two of driving the ECU should adjust the fuel maps and drive the air / fuel ratio back to 12.5:1 RIGHT? This allows you to keep maximum gains while maintaining a safe air / fuel ratio.
So as you add more mods to the engine the ECU will continue to modify the fuel maps to compensate for better engine breathing (efficiency) and keep maximum gains. So long as you do not exceed the maximum injector flow or allowed compensation in the fuel maps.
Am I close?

Re: Chebosto-----Re: DETONATION
Hey Jelledge--
The 12.5:1 A/F ratio is programmed into the new Technos ECU, so when you first put the ecu into the car, your computer will attempt to learn what your car currently has, and from what i've seen, its normal for some slight detonation in the very beginning , but immediately the program learns and ping should go away.
you are correct in your assumptions about adding the intake, the car will try to correct to a 12.5:1 ratio, thus maintaining a safety barrier, but still more aggressive and power developing than your OEM program. the ECU is setup to allow all major NA bolt-ons-- headers, ypipe, exhaust, test/cat-pipes, intake, and the plenum....
you should not worry about detonation in daily driving.. and/or heavy spiritied driving. Quality of gas also plays a strong role.. those outside of California have the luxury of 93+ octane... the Technos reprogram could have been even more aggressive if everyone had 93+ gas, but alas to make sure everyone has the same safety buffer, the code was written for 91 octane. But it doesnt mean everyone will get the same gains. those running higher octane should be even more efficient!
i typically run a bottle of octane boost every third fill up to keep things interesting..

Thanks Chebosto
Yup that is what I thought -- thanks.
I think a lot of people on this forum simply don't understand that an ECU will adjust short and long term fuel maps to try and maintain a certain A/F ratio (except at wide open throttle - for now). Adding mods like exhaust and intake simply makes the engine more efficient at breathing and the ECU will compensate and maintain the A/F ratios. (short of turbo or nitrous of course).
I bet also, that with the Technos- ECU upgrade it would take a week or two to get the full benefit as the computer needs to also update the long term fuel maps...?
Thanks for your support and efforts in getting this to the Z community despite what some people on the board may say. It is people like you that make the Z heritage fun and enjoyable.
Now how about a group buy----

those graphs look odd... i think you got leaks in the exhaust system... look at how jiggity the lines are... perhaps its leaks before the sensor and the sensor is picking up oxygen and leaning it out...
did you talk to danny?

i think if he had exhaust leaks then he would know.....exhaust leaks are very noticeable.

Here is the problem I see with the TS ECU. The car already knocks when it's hot here in California. Especially with our crappy 91 octane gas. From pulling plugs, I can already tell you that the front cylinders run kinda lean and that is why I think I am gonna get the Crawford Plenum. I think Nissan has kept the mixture rich on purpose to keep the front cylinders from going KABOOOM!!! ala the S2000 which has a similar problem with cylinder #4 I believe. Now you lean out the mixture even further and it seems to me, you would be asking for trouble, especially in California.
I think that real gains will be found with the Crawford Plenum and a set of cams.

I have spent my $595+$25 S+H for TS ecu, I drove my car almost 100 miles today.
I need more time to be able to give a positive review of their product. I am not comfortable telling others to buy this product yet.
I have had no spark knocking, or other "problems", but I have no other gains to speak of. Th only area I had to check gas mileage had a 8-10mph tail wind today, 55mph-6th gear showed 33+mpg, might be tail wind might be improved, need more time to check because my around town mileage was showing 12.4mpg
which seems mighty low.
More time and mileage will be next week since I start my 4 days on work rotation (12hr shifts) and don't have energy for long drives, but I will have 4 days off middle of next week for detailed observations.

So, once again, I look forward to hearing what you have to say.

I have done enough racing and auto related hobbies that I don't want to give TS ecu a review without some seat time. The first drive after the ECU didn't blow my socks off so the little details are what is goimg to make me suggest this to others. Do the seat time and the "FEEL" thing before I jump on the Technosquare band wagon.
I feel my "family" deserves an honest review.

I am still looking for feedback so I brought this thread back to life.
To those who have purchased the ECU PLEASE give us an honest, straightforward responce on what to expect.
And to those in Cali, are you still pinging or did that go away? (or never happen?) Even in this heat?

I agree.Where are all you folks that have the TS/ECU flash?We are anxiously waiting for results & street driveablity.Regards,Tom ps:I have emailed TS about the flash for the 5AT & I will post info when I hear back from them.
