The "let's brainstorm how to make a piggyback work" thread

[ChinoCharles]

Thomas, I'm no tuning guy by any stretch. You know that. What I will do is refer them to a more knowledgeable party stateside so they can have some intelligent discussion, rather than me trying to type everything they say and saying "mm-hmm" a lot.

Would anyone like to volunteer to e-mail me their contact information so I can put them in contact with PP if they respond? charlesluzar@hotmail.com

That's some great team work and effort to get this stuff figured out, can't wait for some feedback.

Hi Charles

Thank you for your email. I have forwarded your email to our Technical Team to see if there is a way to assist you. Normally the problems with certain cars are that some ECU's are really REALLY clever little units. Sometimes these ECU's detect that you are trying to intercept the signal and just don't like it and then causes endless problems. I am not too sure if this is the same with the Yaris as well but I let you know once I get more information from our Technical Team.

Kind Regards

Hi Charles

We have not test our products on a Yaris before but we are busy looking for one. I will let you know what is the results once we have found a car and have done the installation.

In the meantime could you perhaps let me know what do you expect from this unit i.e. more power, more fuel efficient etc. and what signals have you tried to tune in order to achieve your requirements and what was the results you got with the other units. We would just like to test these aspects as well to ensure that if the unit will be able to meet your requirements.

I will get back to you on the testing once I have more information.

Kind Regards

OK guys, help me put together the response. I would suggest that Thomas make a post after this and you can help compile our data and as soon as everyone is comfortable that we have covered all of the bases I'll shoot the e-mail out. If they can conclude that their unit will work, I have a local tuning shop that uses Perfect Power's products heavily and I could be the guinea pig. I'll need a piggyback down the road anyway.

The focus of the discussion should be on power. There is a larger demand for power from tuning solutions than there is fuel economy, although I will make a point to mention that if they can improve fuel economy on a closer to stock Yaris that may generate interest as well.

urgh I'm not gonna have the time to write that up tonight, hopefully tomorrow. Plus I'd really want Garm to chime in with more details on his AEM experiences.

Also Charles, keep in mind that if they have a test car in south africa, the ECU may not be the same as yours. Seeing how seemingly easy it is for SouthEast Asia tuners to set up turbo kits, I am quite sure the US ECU is a lot more finicky.

The tune will increase crusing fuel economy if done correcty.

I can help with the response if needed. I'd even be willing to test it.

Yes, if you can start writing it up, post it here, then we can add/change what we need

As for testing, the more guinea pigs the better

hey guys!

i stay in South Africa , i will give this guy a call , and see what he says.

i think the US and south african yari's should have similar ECU's , so if it works on ours , should work on yours.


a friend of mine have a honda Jazz 1.5 vtec / honda fit ,he fitted a UNICHIP , and he gained 4 kw from the chip alone , so not to bad , but then again , the ECU might be different.

i'll get back to you guys.

OK, I'll respond with that first and that will give you some time to compile your list of questions.

Marcell,

First of all, thank you for the timely and comprehensive responses thus far. It speaks well of your company and your product.

I think it is important to point out that part of the issue we are having in the US is that our ECU's are different from the rest of the world. They are a little harder to work with. There are numerous examples of successful tunes in Japan using piggybacks. We in the US have nothing but horror stories.

If South African Yarises have similar ECU's to ours, then this will work great. If not, then you may want to source a US car to do testing on. I would be more than happy to help. There is a shop in Ashtabula, Ohio called Twisted Innovations. http://www.tidyno.com They originally referred me to your company two years ago. When piggybacks came up in conversation on the forums, I decided it was probably time to reach out. If we could come to an agreement on how to handle testing the platform on my car I would have no problems with that. I have a car I can use in the meantime.

My engine has the following bolt-on accessories:
HKS Hi-power axle back exhaust
Simota carbon charger SRI
NST crank pulley
NST alternator pulley
NST water pulley
Megan 4-1 header

I have aspirations to add a turbocharger or supercharger down the line. I know your piggybacks are particularly useful in chorus with nitrous systems, so that could be an option too. I also know of various other US owners that could offer assistance. If your company is willing to help us, we're more than willing to help you.

Let me know if you believe research done on cars in South Africa will be applicable to our market. We can go from there.

Thanks again Marcell.

Charles

Going back to the Unich topic...

The memeber using it is REVOTURBO from Indonesia

They are using Dastek unichip type Q and dastek turbo module

However they are using larger injectors and a 5th injector set up

The Unichip turbo module will support a 5th injector, so that is not a big deal. Pretty standard

5th injector's a bit of a last resort solution/hack though, isn't it?

greedy F-manage
he Greddy F-Manage enables you to control the feedback to your ECU, opening a range of tuning possibilities.
Features

* Controls feedback of air/fuel ratio to the standard ECU
* Does not control air/fuel ratio, this is used in conjunction with fuel controllers
* Can be used simultaneously with e-Manage Ultimate data logger
* DIP switches enable control of maps and switch on/off

well hellooooo there! *starts reading up instead of working* arrrrgh

[eTiMaGo]

Doesn't seem to be officially released outside of Japan, though, so good luck getting instructions in English...

Seems to have a NCP91 harness already, nice.

But, the million dollar question, will it be able to dance around the ECU's emissions checks...

well i was told it was for new car with relearning issue, so any one got the $ and just order it already hehe because when reading this thread i think diz is the right gadget all of u been looking for
