680cc not working with dsmlink.

[mitsuclipsegsx]

i went to victor research to get dsmlink installed and dyno, i installed pte 680 ccfrom SBR in june, and victor told me when he put in 680 for link it would even run, he put 550 and it did? Did sbr #### me over.The guy did say though thr sticker matches the 680 not the 550

I think you may have 580cc injectors.

What is your base fuel pressure set to with the vacuum hose disconnected & plugged? What did they have to enter for the global then? PTE injectors are known to flow less then they are rated for, as they test them at an elevated pressure compared to the industry std (& what we usually run) of 43 psi.

i have no idea.,the dyno place did everything i dont even know how to use link yet... website wont even let me make a thread...

38psi and when i unplgged it the same, someone told me then i have a leak?

 

[myblack98gst]

it should have been at 42psi with the vacc. unplugged and around 36ish I think with it plugged in..

you need to figure out why the fuel pressure is lower than it should be.

bad pump, regulator, filter etc...

 

[daren_p]

If your base pressure with the VAC line disconnected is in fact 38 psi this is your problem. Injector flow is directly related to pressure and the base pressure on a 2g should be 43-44 psi. If you raise your base FP to where it should be, it should clear up your low flow problem. If it reads both 38 with the VAC line on and disconnected you have some other issues. Time to put that boost leak tester to work, but obviously your car should be making some vacuum so have you verified proper operation of the fuel pressure regulator? Which FPR are you running?

I don't think that is the only problem. Even if he is at 38 psi base fuel pressure his "680 cc injectors" would still flow just under 640. If that's the case then with 550cc injector settings (-18% fuel) he would be so rich that there is no way it would run fine.

Like I said he probably does have other issues as well but you have to remember PTE over rates their flow, that is they test them at an elevated pressure, their 680's flow 650 or slightly less at the industry standard 43 psi. So at 38 psi there probably flow more like 600 cc (haven't done the math). But we also don't know exactly what they used as their global setting & if they even got the fuel trims inline.

Is your chip burned for 680's? Didnt you have to give that info to whom ever took the order? I may have miss read but, it sounds like he didnt try anything with the 680's in, because it would not run. Is this wrong?

Not to sure exactly what your trying to say, maybe bad wording or just me but the values he got the chip burned for are just the default values that will get reverted to if the ecu loses power (ie disconnect the battery) This doesn't mean that the only size injector you can run, you can adjust the global (setting used to compensate for different sized injectors) to anything you want with the DSMLink software at any time.

I understand this, but if hes burned default for 550's and puts the 680's in, it will be unstable and I was wondering if his tuners actually messed with the global and dead time or just said wow, this isnt running right and then quit. Know what I mean?

Well i think VR sucks! Looked at my settings today and everything was set to 0. even for injectors, like i am using 450, then i figured out why it bogged from 2-2.5k, they didnt invert the cas... but do i have t change the plugs, it runs fine now, except the fuels ####ed up. before link was installed i was at 43psi fuel now is 38. jeezs i take it to get tuned and they dont do shit.

 

[MyBeatGSX]

Good old VR.

How have things worked out since? Did you take it to Pruven?

 

[FORMONTOYA]

Yea, just grab your manual from the CD that came with your DSMLink and follow the injector setup procedure as far as global/dead time goes, then do your 15/5 minute run to setup the low/mid fuel trims (page 17 of 31). It's really a simple process and not something you should be overly nervous about. Just in the beginning don't mess with the WOT RPM related sliders for fuel/timing until you've figured it out a little better, it'll run a little rich with the sliders at 0, but you'll be fine. But DSMLink is a super simple product to use. Don't pay someone to tune with it.

I will be taking it to pruven asap

So what exactly did you pay them for? Sounds like nothing to me, I'd be asking for my money back. DSMLink is extremely user friendly, even for the first time tunner. I'd save the money you would be spending on paying someone else to tune it & put it towards a wideband and tune the car yourself.
