If you're talking about Nathan's race car. Peter found some issue with the sleeve or something. It had nothing to do with the piggyback.
He went to XEDE because he has a custom cam grinde and new head on the car. The SAFC is to basic for his setup in short.
There would be little difference between the Unichip and SAFC except the tuner of course.
And how much would you pay to find a tuner who isn't going to lean out your car because he doesn't want to listen to you about cly5 and 6 running leaner from factory?

The lambda (o2 sensors) sensors are only intended to trim air fuel mixtures whilst in closed operation (to hold air/fuel mixtures to lambda 1 whilst in cruise conditions) so what happens when you are using throttle positions outside of the closed loop area? The o2 sensors have no input to this condition, that is throttle positions outside of the closed loop area.

He also said he thinks the reason why he cant get replicable power out of the car is because of the ECU. So if the Unichip doesnt address these 'learning/adjusting' issues then its no better at all. And not worth the money over the other solutions.

Not pointing fingers but as Peter mentioned it is also up to the operator to keep factors consistent. So what guarantee do you have that APS will be consistent either?

Also I think Peter mentioned timing was not changed. So why not just get a SAFC II ? and save some dough.

Take a step back and have a look at the target market of these cars. There is not really any reason for us to fudge numbers.

You may find the following an interesting read as it not only refutes the claims made by the Unichip competitor, but to our surprise, it also demonstrated some serious inadequacies in the signal replication quality of the other brand of product. The manufacturer of the Unichip computer finished by saying "We further invite anyone with an oscilloscope to verify the above statements for themselves." - Pieter de Weerdt - Dastek
http://www.************************/fa...de_signals.htm
Those who live in glass houses shouldn't throw stones
In finishing, I can assure all 350Z forum members that APS, being the Australian distributor of the Unichip computer has gone to great lengths to test this technology on a number of 350Z cars over many months and many thousands of kms.
This testing was to not only prove the additional engine performance, but to also ensure that the Unichip computer continues to operate in perfect harmony with the factory Nissan ECU and that the whole engine management system is totally glitch-free. This is one of the longest testing periods we have ever conducted for the Unichip product prior to release.
There is a forum member who has been conducting some independent testing on a Unichip enhanced 350Z and with any luck, he may find time to post his impressions to date.
APS is 100% confident in the ability of the Unichip computer to deliver optimum tuning results for the 350Z.

Seeing as the APS dyno is the only accurate dyno in Australia, I called to book a power run and see what the true power output my Z is, only to be told... "we don't offer that service"
So I maintain that my car has .1kw more than a Z with Hitech and unichip

I actually put off buying a Hitech exhaust in favour of your system.
(willing to wait)
Only trouble is i wont know the gains if I cant get a dyno before/after.
did I mention .1kw ?

APS,
Does the Unichip allow for the ECUs ability to learn and change maps based on different circumstances?
If so how does it handle these changes?
This is the main problem with all the piggyback ECUs on the market at the moment for the Zed. If the Unichip doesnt handle this differently then its no different from any of the other solutions.

Thanks for that info, not bad.
One question, was this ever released?
"The Unichip rev limit module is currently undergoing testing and should be available early 2001."
Its mentioned half way down the page.

OK I'm the forum member with the Unichip fitted, that said here's my impresstions. Let me first say that all the dyno's I've had done have always been lower than the rest of you guys which has always concerned me in base (std.) form it was 145.4rwkw with mileage at around 5000k's, then the HT was finally installed the std car's baseline was dynoed again 148.1rwkw and with the HT 162.5rwkw gained around 15rwkw I was happy with that gain plus a great sounding exhaust to boot. Back to the Unichip the car has now done 28,000k's the first base dyno APS did peaked at 155rwkw sh#t I though to myself big difference then Peter pointed out my car was dynoed on a different type of dyno (Dynamic Test Systems) anyway they fitted and tuned the Unichip re-dynoed and 166rwkw was the result, those are facts as they happened. The power and torque increase are there right across the total rev range, I notice it most in 5th gear when changing lanes to accelerate pass cars, the car responses quicker to the throttle but from 3800rpm upwards WOW like a mild set of cams have just been fitted, it idles smoothly and the engine generally feels smoother, so with other mods cams, plenum, hiflow cats or what ever this little baby IMO will get the best out of them. ASP is continuing the testing to check is long term reliablity etc., but it is so far looking really good.
Is this a good mod? if it checks out ok in the testing phase, YES YES YES and definitely YES

Thats fantastic to hear.
Its not always good to be the first with a new product, so thanks for being the brave one and sharing your thoughts about it.
It does sound promising that you actually gain 11kw on the same dyno and the car is more drivable, which is a plus, rather that just gaining 11kw @6000rpm.

Cool great to hear. So how long is the Long term Reliability test? 100km?
Also David, All i want to say is WOW!!!! You Ordered the APS TT. Cool
when will that happen?

Am I missing something here as I don't understand how anyone can obtain stock power figures for this particular Z car if the car does not have a stock exhaust.

Murray, David said.
before he install the hi-tech on the same Dyno:
Stock = 148.1 rwkw
After fitting hi-tech on the same day = 162.5 rwkw
Then Installing Unichip with hi-tech on already same dyno (APS dyno):
before Unichip with hi-tech = approx 155 rwkw
With Unichip and Hi-tech = approx 166rwkw
so basically the Unichip gain another 11rwkw with hi-tech exhaust.

You obviously can't mate, unless you put the stock one back on, which isnt such a far fetched idea when your talking about information gathering which will help sell a product to the public, I was after clarification as it was a bit confusing the way he wrote it.
Yun,
Thanks for clarifiying!
David,
Would you say the gain felt after adding the unichip is the same sized gain as you felt when you added the HiTech exhaust? Or a bit smaller or a bit larger?
Since all the dyno readings everywhere are so different and we dont have the stock dyno graph to compare the gains, im hoping your opinion might give us an idea of how large the gain is. Not scientific but then we might know how large the gain is.
