We have listed the full list of parameters in the previous post. Those are the only parameters changed in the ZChip process. If it is not on the list, then it is not modified by the ZChip.

 

A reposted list would be helpful this far into a thread.

I went back and read the entire thread. Here are the only previous posts I can find in the tread from you (edited to show relevant info) :

"The ECU doesn't determine anything.

The ECU looks up tables whether they are programmed in there directly or whether you have a less expensive device that looks up the same numbers that would be programmed, but at a much less expensive price."

(and)

"This is incorrect. The boost is unaffected by the ZChip when using the stock BCS.

The ZChip has multiple maps to custom tailor and process the MAP sensor's signal to tune the car into a custom load cell of fueling and ignition timing. There are thresholds the ZChip will ignore processing the signal and pass through the data with zero processing and there are programmed high performance areas of driving which WILL be modified by the zchip and performance will be much improved 60-85whp avg."

Is this the full list of parameters you were refering to?
Thanks for your input.

 

i think he got confused about which thread he posted the list in. he posted a list in the cobb AP vs. zchip thread.

i would like to know however (i don't feel this question is too off topic or requires a new thread) what the zchip does with how rich or lean it runs. does it affect afr's at all?

 

It seems as if there are 2-3 individuals posting a number of threads about the ZChip. Its a process keeping up with what seems like a repetition of the same info discussed in each thread.

 

I don't see how it would be possible for the zchip to increase the rev limit. So the answer should be "No, it cannot change the rev limit".

Also, it's not changing the maps in the ecu, but more along the lines of making the ecu look at different cells within it's own maps.

 

I agree with madcows and I think you are trying to mislead everyone. No matter how you try to spin it, all you are doing is altering the MAP signal.

I also agree with what everyone is pointing at and that is that you are now flashing your ECU. I don't believe for a second that the new track times would be possible without doing so and you would still be running a mid 12 if you were in fact solely running the Zchip for tuning. Here are the reasons I think this is the case: 1) In the 3 videos you have posted at the track and on the dyno you don't shift to 5th, you rev out 4th gear to over 111 mph (Not possible if using factory redline); 2) You stated you have “MIVEC custom mapping” which is something the Zchip cannot do; and 3) You stated “ECU controlled boost” and showed levels of 30+ psi.

 

We have the ability to reflash 2008 Evo X, MR and Ralliart 09+

We would not be experts in our field if we did not test all technology available to be the best at what we do.

We have done independent testing on ECU boost control to experiment with it. We have since switched back to manual boost control so that the ECU cannot change the boost in case of any CEL codes during testing.

We have worked on custom, JDM, EURO mivec mapping to test the potential for power gains and haven't seen conclusive results that any significant power gains have been demonstrated.

Rev limits are able to be changed via ecu changes for those in the 390whp and higher power ranges. 95% of the 4b11 consumer base are well below this power level and are not running water injection.

We have run the car as high as 33.3psi on the dyno, 34.1psi peak on the street however due to the volumetric efficiency of the engine at these RPM ranges, peak boost at the strip is 28-30psi.

All of the modified map changes within the ECU are a result of the ZChip's custom programming. We tuned another today at 342whp/333wtq bone stock.

You have made mention to acknowledging the modifications and changes we have made to our car, ever slight, but notable, yet claim that we should still be in the mid 12's?

Our FIRST trip to the track was 12.7 @ 107.42mph BONE STOCK with MBC/ZCHIP

Our SECOND trip to the track was 12.02 @ 112.70mph with TTP testpipe, Forge WGA, high boost (28-33) on 93 octane with water injection to cool the intake charge at full weight.

Your educated opinion is that we should be in the mid 12's? Really?

 

this has been answered, it uses the MAP sensor signal to redirect where in the ecu's fuel and ignition maps the ecu should look, it goes without saying that it leans the car out from factory set fuel

 

My educated opinion is that to get the current results you had to reflash your ECU, and that you did not state that you had to to obtain these results (this is called False Advertising). One of the biggest selling points to the Zchip is that it involves no reflash of the ECU, but apparently now to run a 12.02 @ 112.70 you need "TTP testpipe with cutout to bypass the stock exhaust, Forge WGA, high boost (28-33) on 93 octane with "water" injection to cool the intake charge at full weight" a Zchip and a reflash.

Horsepower shouldn't designate when the rev limiter needs to be raised, on the 8's and 9's it was included when getting a base flash.

"All of the modified map changes within the ECU are a result of the ZChip's custom programming. We tuned another today at 342whp/333wtq bone stock."

Really? The Zchip is not modifying the ECU's maps, all it does is trick the ECU into using the factory maps at a different time then it would under normal operation.

But hey, at least you didn't deny reflashing the ECU. That's a step in the right direction.

 

Once again, thread cleaned. If you got an infraction, don't bother complaining to me, we no longer have any tolerance for people who like taking things off-topic or otherwise disregard our warnings. Carry on.

I can't even go to work for a day without this thread falling apart. (humor to calm us all down).

I have to agree, let us please keep on topic. I know that it is very easy to get side tracked and enter into interesting conversations, but it will continue to result in closure, or until one by one we all loose our previlages. If I may suggest, re-read your future posting before submission and ask whether or not this may offend anyone or go against posting rules as well as if it is on topic. I think many points are valid, but not necessarily appropriate in this particular thread. A new thread can be made to address those new issues that come up. I am not supporting or defending any body here, just want the ship to sail straight.

In other forums as well as Evom, it has been helpful to post a link to the other thread as a sole response in order to not have to make further explaination within the same thread to address a question. Could someone link the Cobb/Zchip thread here for easy of viewing please. Thank you.

 

You said that the mivec tables don't make any more hp but don't they make the turbo spool faster thus making more area under the curve ie faster car? Anyone have any idea how you would be able to change the mivec with only changing the map voltage? They must have one heck of a crazy algorithm to get this done.

 

thought this post was usefull and I wonder why it was deleted?


Actually I think I can say that NO, 12.0 is not the "top" of the game for the Evo X. When we ran 11.8 months ago untuned. we just gota low boost tune and ran yet again an 11.9 holding just 22lbs. People would indeed like an answer for a very simple question. How if you claim to ONLY be Z-chip tuned are you hitting 116mph in 4th on your dyno, wich you yourself claim to be dead on and you're doing this on the stock limit? That's a very simple and legit question to ask of anyone. I must also add that I got off the phone with a rep from mustang dyno and they sure confirm that their MPH read out is dead on

 

MIVEC tables simply control where (in the rpm band vs load) to pull or add cam timing (whether intake or exhaust)

it is used to make the turbo spool faster (stock) but what i believe there saying is that the stock tables are already at peak performance setting, also the MIVEC tables arent effected by the Z-chip, only fuel and timing...feel free to add other tables i know those 2 definitively are used

 

It may be a good question to ask but it is off topic to the original question posed in the title line. This type of posting is against forum rules and can result in not only removal of the post, but disciplanary actions by the mods or admins. Be careful what you post especially in this thread. Please take no offense in this friendly reminder.
