Evo Injectors on DSMLink

[BoostFrenzy]

Hello all. I just have a quick question regarding injector defaults when ordering DSMLink. I will be ordering DSMLink very soon and I have a little problem with what I need to have as my injector default. I currently have Evo VIII "560cc" injectors and have no intention of changing them. I have heard many times that they actually flow around 580cc-590cc. So would I choose the RC 550cc to stay close to what my injectors are rated at, or choose the PTE 580cc injector because that is closer (if not exactly) to what the Evo VIII injectors actually flow? I am trying to get this answered so it will be easier to tweak the global fuel and dead time when I first start it up. I'm leaning towards the PTE 580cc because I think I might run lean at idle if I choose the RC 550cc choice. Can anyone shed some light on my situation?

Any helpful information is greatly appreciated.

A guy on the link forums had them tested at 600cc's. His global was set at -23%. That's all I could find for now. If you're getting DSMlink then you'll be able to access the forums and you'll find pretty much whatever you need on there.

Stock evo injectors work faster than our stock injectors. Literally. DSMlink has settings for a global correction as well as deadtime. Deadtime = the speed in which the injectors pulse. DSMlink was designed for our DSM stock injectors. This means a zero global setting plus a zero deadtime setting is the stock injector settings. You cannot input a negative deadtime value to try and compensate for the evo injectors. This is what makes them flow more in DSM's. They flow more than the 560cc value because the faster deadtime is unadjusted for. A global setting of -23 sounds about right but I would venture to say they would range from -21 to -23. The deadtime value would have to be left at zero.

I would recommend these injectors to anyone. 550cc injectors these days are too small for even a properly setup small or big16g car. I would know. I maxed my FIC 550's with my standard big 16g.

TSG59_Steve:
I am indeed looking forward to having access to the forums. Because I know I can learn a great deal of information from the many tuners on there.

Black95TSIawd:
This is some VERY useful information. I knew about the dead time thing being different because a friend of mine explained this to me a while ago but I forgot exactly why they flow higher. I'll have to remember this thread when I actually receive Link. Thank you.

Although this is some fantastic information, it still doesn't answer my main question. Haha.
So to make it more clear. What should my chip defaults be for my injectors? (Since my Evo injectors are not listed). I just want my car to be manageable to drive if my battery dies and I don't have my laptop with me.

Again thanks for your posts.

Tell them to set the chip up for the EVO VIII injectors. Since the deadtime is negative relative to the stock injectors I don't think their UI can deal with that yet but the initial setup can.
If your going directly to ECMTuning for your DSMLink, Tom should be able to make the adjustment.

To add some information, I'd try what Steve said & ask them if they can do/have a chip for the evo injectors as it sounds like their global will be abit more vs the other injectors you have mentioned.

Here's abit more info for you, actually having the chip burnt for PTE 580 will be worse the for RC 550's. It sounds like because of the evo injectors quicker response they need a global around -21% to -23. To compare RC 550's come with a global of -18% & the PTE 580's come with a global of -16%. While this seems strange, the reason for the higher rated PTE injectors having less compensation is that PTE rates their injectors at a higher then industry standard pressure. The standard is to rate injector flow at 43.5 psi, while PTE for example would rate theirs at say 50 psi so their rating is higher then what you would see with a proper base fuel pressure. Basically if they can't burn them for the evo injectors, get them done for RC 550's, your global will be closer to what you need vs the PTE.

Let us know what you find out on the EVO8 chip defaults as I'll be going the same route.

Alright thanks. I'll be sure to talk to Tom at ECMTuning.

More GREAT info!!! Thank you!

Question has been answered. Thank you almighty Wisemen

I will be sure to update.

Alright Evo injector guys, I have the answer. I emailed ECMTuning and got a response. Here it is:

"Just select the closest match and then put a note in one of your address lines to remind us what you need. Something like "*** EVO8 injectors" will work fine.

Thomas Dorris
ECMTuning, Inc."

So I say 3 cheers to ECMTuning.

I do still say email them though so I don't end up being the *burro* who said "Yeah, go ahead and order the chip for the 550cc injectors and say somewhere you want Evo injectors and then complain when you get the wrong chip. It'll be good fun". So please do email them. This will do 2 things:
1) Your order should come right
2) They might take the hint that people DO run this injector and that maybe they should offer it as a choice instead of getting pummeled with emails asking for them. Boy how I love future proofing.

That is all.

I finally got around to ordering Link

But I have not received my confirmation email. Ordered at about 3:30PM (West Coast) Friday , and I suspect that they are closed on the weekends.

Filled it out exactly the way Tom told me to and now I wait for the email (to pay the bill) and package to arrive to test how well their settings are for the setup.

BTW, I only have USB ports on my laptop. I heard that you can get the adapter for cheap on the Link forums. Is this true? I don't want to go and spend money I don't have to on an adapter that is ridiculously over priced.

 

[steve]

Yes, order the keyspan adaptor from them too.

Thank you kind sir

I got kind of a wierd question related to this. I got fic 750cc injectors, and accidently picked the evo one. Do they have a negative deadtime also, compared to the dsm fic 750's?

I don't believe there is any difference between the FIC 750cc for the EVO and the FIC 750cc for the DSM. The dead time for the injectors should be identical.

The factory stock EVO 560cc injectors are faster to open and close than the factory stock DSM 450cc injectors and so they need negative deadtime corrections. I'm not aware of any other injectors that we use that are faster than the factory 450s.

If you have any other questions about what you bought you might want to contact the vendor.
