Hi all,it been said to me(from my neighbour who friend got a getz like mine) today that new cars,the Ecu reset itseft when driving now and them.(You can feel it.)I been having some problems with my Getz (1.6 man.)for the last 11 months:rant: But Hyundai(were I got it from) HAVE NEVER said that they do that.It been in their workshop almost every month.:roll:
The TPS and MAS been replaced so far.

What do every one here say to that:think:

Edit-Forgot to say I bought it new last may.

Nope they don't 'reset' themselves.

Best off asking about this on a hyundai forum?

ECU's don't typically reset themselves - what problems are you having?
Try hyundai specific forums, as suggested.

The problem is this-when driving along,now and then the car is surging a bit.Don't like it at all.:rant:It does it more going down hill and slowing down.It far worse when I drive on my own:nuts: So far the TPS and MAS been replaced.

On the Hyundia forum there talk about some cars have hesitation in acceleration (like the engine is being held back).In my case,it holding the car on say,80km/hour.They were talking about Speed Density Tune.:eh:

Newer cars have a "learning" ECU. When you thrash it, it tends to "learn" you want faster acceleration, and higher fuel input. When you drive like a grandma, it changes lower and takes slightly longer. What you'll find is that you've probably been treating your Getz very well, and its "learned" to do things to conserve fuel, instead of accelerate. When you thump it, it tries to accomplish the acceleration without decreasing the fuel economy, etc.

I tend to thrash my Magna, and my ECU knows this. When I drive it real nice and all, I can make it to 3500rpm before it leaves first gear. And it lurches when it does change. And it "learns" when I drive slowly to change to the more economic mode.

My advise would be, give it a little stick every-so-often, and it'll soon learn to accelerate when you need it.

BTW I could be wrong.

word, mine loves changing out of first gear at 4700rpm.

IIRC the 2nd Gens do not have a learning tranny?

This was one of the selling points of the TE with the INVECS auto box.

yeah mine has learned to hit the limiter before changing:redface:

the second gens had learning ecu's but not tcu's

Wouldn't that only apply to an auto? The OP has a manual.
I had a similar problem in my TR, which turned out to be the ISC, not sure if your car has one or not, and why it would be broken after only a year, but maybe give that a shot?

Yea,my car a manual:rant:

I was under the assumption that the shifting was controlled by the TCU, but things like fuel economy, etc. are controlled by the ECU. The TCU in the TE-TH, afaik, is really just a reference to the ECU. When the speed of the output shaft doesn't increase at a fairly high rate (with a minimum RPM and all that other stuff), the TCU changes gears.

If the ECU wants to stay fuel economic, but you wanna go fast, then it will stay at the lower fuel consumption, etc. until it notices that the exhaust composition has changed (more air, but no more fuel) before it finally increases the fuel flow.

But yes MADDOG, you could be right. O.P. Check the ISC as well.

(P.S. I thought about whether this would affect a manual, and it seems realistic)

Yeh that's all true for an auto, but unless his ECU is faulty (possible) you wouldn't notice the ECU putting more fuel in as it would only take the ECU a micro second to think and then do it.

which turned out to be the ISC

What is an ISC?

Idle Speed Control aka. AIC Auxilliary Idle control - used by the ECU to control extra air past the throttle body to prevent stalling etc.

Ok. Haven't had too much experience with manual's, only ever been around auto's. Hopefully I'll get a manual soon.

not tryin to hav a go at u but i think u hav a lemon. a lot of things had been replaced in a short period of time. maybe replace the car b4 u lose more money value to it:think:

Can't as this stage,paying off $10,000 on the car.:disgusted
