For months now, many people have been talking about the power gain differences between a reflash and the new Z chip. The problem is that the Z chip hasn't been dyno'd at anyone else's shop other than TTP's, and with their dyno reading much higher than most, it's hard to really compare it to the results from an EcuTek flash. Now, it has already been shown that stock X's with ecutek and the Z chip alike seem to both run about the same times down the strip, so that is something, I suppose.

But, what I really want to see is both forms of EMS tested on the same dyno to finally give an accurate comparison between the two in terms of both peak power AND area under the curve. This will settle a lot of confusion regarding how engine management works and how dynos read. Now, This topic seems to be a touchy subject for many so all I will say is this: This thread is for the purpose of posting dyno graphs comparing the two and discussing the differences.

This is NOT a place to bash either product, so if you don't have something worth contributing then don't post at all. So, with that said, anyone have anything?

 

oh boy

 

Great idea, subscribed

 

isn't ttp the only people who can tune the zchip right now? so it would be hard to compare a custom ecutek tune to a base zchip map, unless of course ttp does the testing

 

I think that the customer can actually download the program so they can change settings - not sure on that one . I know of people looking into both the ecutek and the zchip , we'll just have to wait and see . I haven't used either one myself .

 

Y'all best keep this on topic and respectful, ya hear?

What alot of people do not understand is that one form of ECM tuning software or product, be it a piggy back, or full standalone, is not going ot make any more HP over the other in itself. The real factor is the person doing the tuning and the quality and combination of mods that will make the power difference.

The only difference in the actual units used to tune the car will be the software and features. Other than that it is what the tuner feels most comfortable with that can get the owner the results HE/SHE desired.

There will be no magical P&P unit that will solve the worlds woes.

 

but not that many people have the knowledge to tune their own car. not sure who has the knowledge to tune the zchip except for ttp. i wonder if tuning the zchip would be like tuning using ecuflash? been trying to decide on what tuning method i wanna go, ecuflash, zchip or ap

 

^^^^I'm pretty sure that all the people that attempted Piggy back type systems were able to pull the same peak numbers, but ended up going with Eccutek, AP or some kind of ECU Flash. When I say all I just mean Perrin's Unichip and Shiv's Procede. I would love to hear why they abandoned a piggy back for a ECU flash. It may shed some light on this topic.i I am interested in this topic and would love to see some 3rd party dynos on both sides Eccutek and Z-Chip.

 

All it would take is two customers with Xs, one with a custom ecutek tune and one with a custom Z chip tune (or one with a mail in flash and one with a base map from TTP (equivilant to a mail in flash in essence), to drive to an independant dyno tuning facility and have the cars run back to back. Easy as pie.

Exactly the purpose of this thread, my man. I've made the same point that you just made a million times, but people don't listen. Instead, they see a dyno graph from TTP and say, "100 whp gain, that's twice as much as any ecutek I've seen... it must be better."

What they don't realize is that like we've both said, assuming that each interface offers similar parameter control, it comes down to the fuel octane's limitations of how much boost and timing can be run, as well as the tuner's skill level. What this thread will do is show that when run on the same dyno, the peak numbers will be very similar and it will hopefully put to rest all of the confusion regarding the reality of tuning for the newbs out there.

It will also show that depending on how a dyno is calibrated, it will vary in not only baseline numbers but gains as well. Let the comparisons begin!

 

This is a stupid test.

Unless the tuning was done on the same car with the same mods the whole thread is pointless.

You act as if you are doing the newer evom members some kind of favor when you, yourself think that octane alone is the defining factor as to what power can be obtained from tuning an Evo X.

This is far from the truth and making statements such as this as well as slanderous statements that our dyno reads high, only indicates that you are the newbie you describe, lacking an understanding of tuning, dynamometers and how each product works.

 

^^^^Interesting Remark to a Possible customer. He just wants to see some cars with Z chips and Eccutek compared in 3rd party areas. I do not think it is that big of a deal. I would like to see it as well. Just to see the products away from the actual vendors on both sides.

 

To those that want to participate: state the city that you live in and which EMS you have (z chip or ecutek) and once we find some people in the same area with both, a vendor/shop owner in that area can chime in and arrange a dyno day to do the test. Now, the tests will need to be monitored so that no funny business goes down, such as spraying one car's IC with NOS to bias the test, etc. So, people... step up to bat and let's get this done!

 

Don't bring your negativity and disrespect into this thread. I never said that fuel octane ALONE is the deciding factor in how much power an EMS makes, so don't put words in my mouth or disrespect me. I know a great deal about engine managament and engines in general, so calling me a noob is ridiculous. What I have said is that ASSUMING THAT BOTH EMS' OFFER SIMILAR PARAMETER CONTROLLABILITY, FUEL OCTANE WILL BE A MAJOR DECIDING FACTOR.

The point was that if you are running a reflash and 93 octane, and are running high boost and timing and are on the verge of knock, that running a piggyback isn't going to magically allow the engine to run more timing without knocking. And I never slandered your shop or products. I have said many times that the Z chip is a good product for people that don't want to do a reflash for fear of voiding their warranties. Saying that your dyno reads high is not slanderous, it's the truth. Your dyno reads a stock X higher than most and shows higher than normal gains than most do.

This in no way means that you are a bad tuner or that your products or services are not good, it just means that comparing numbers from your dyno to another can't be accurately done and for a good comparison of the Z chip to ecutek, the cars need to be dyno'd on the same dyno. Coming in here and trying to discredit this test or insult people doesn't make you look good, and unless you are scared of the results revealing something contrary to what you have posted in your independant tests, you should have no reason to worry. Now, if you can't be respectful then please leave.

 

+1 seems a little unprofessional. I would love to see this test, esp if we could get the same car done
