My car has gotten around 20 ECUTek flashes for tailored tuning and I have been playing around with ECUFlash and have not yet seen the ASC light turn on my car or any other cars that I have flashed.

 

Simple .. ECU signal mismatch ..

Whatever you hook up to the car that is not from the factory.. you're going to throw CEL .. if not now .. later .. at one point in time ..

piggyback modify the signals .. these signals cause mismatch with the wheelspeed sensors and the airflow sensors ..

Boost controller modify the engine load .. now your TPS and your engine load mismatch ..

MBC .. same as EBC .. especially at part throttle .. some people say the ""NEVER" get it .. thats because they "NEVER" gone into that region yet .. the weather is turning cold.. you'll see more of the MBC issues real soon ..

 

There are ZChip has users that have never had the ASC light come on, even with a bit more aggressive tune than the basemaps.

 

None of my customers have had any ASC light issues, from any part of the world. The JDM ECU's are all good too. I have flashed some cars over 50 times (due to changing modifications and testing) and have yet to have a problem when using ECUTeK.

 

The main thing that we all don't understand yet, is that the ASC/ABS module is seeing something is outta whack with the engine, but the engine controller isn't detecting an issue. It occurs to me that if the engine detected a fault, it would set a code, then subsequently the ABS/ASC would be disabled. BUT, that isn't happening so it makes me wonder exactly what the ASC is really looking at in order to believe there is a fault. Until we know precisely which parameters the ASC is monitoring (for the specific DTC it sets), then it's all speculation. I cannot stress how much I'd LOVE to see someone pull a code at this point!!

 

I have the WORKS P2 flash and have not had a single ASC light issue.

Just to add that I have tuned just under 100 Evo X to date - both standard and SSR version - not one with any cel issue yet - I am using ecutek

 

I have done a lot of X's and I have not had this issue either.


EDIT--Using Ecutek BTW

Why do you think some people get the light and others do not?

 

As a prospective customer, I'd like to ask: does TTP/Zeitronics see this as an issue that must be resolved? Your responses appear to be of someone who has pushed long and hard to get this ready and now when an unexpected problem appears you wish it would just go away. So, do you have a plan to resolve this issue?

 

I'm sure they are working to resolve this issue, despite what might appear to be a defensive stance.

One has to be realistic in the sense that no vendor would continue to sell a product that could be percieved as flawed when there are other alternatives out there that are not causing the same issue.

I hope they get it rectified, as I think the z-chip has great potential.

 

I bet they are running in "Snow" mode which practically disables traction control.

 

We are reviewing as much data as possible comparing those who do not get it to those that do to try and learn as much as possible about it. It very well may turn out that those with the dealer update flash do not get it.

Time will tell.

In the meantime, the ZChip has been busy winning 2 SEMA Global Awards. From what I understand only 10 of these awards were given out at SEMA 2008 in Las Vegas last week out of 2000 products showcased and the ZChip took home two of them.

 

If you were a betting man, you would have lost because the ones not receiving the light only use TARMAC mode.

 

I have the Dealer reflash for misfire above 5KRPM, got it done about 3 weeks back, and I do get the Service ASC warning.

In Tarmac mode, I get the warning all the time, even normal driving.
In Snow mode, the warning is less frequent, only occuring near redline shifting, especially from 1st to 2nd gear.
