ECMlink Need help with tuning

[Myk984g63]

here is my ECMlink data..

May want to start with inspecting your front o2 sensor. It's locked at .80v.
TPS can use a tweak to zero out your throttle. Might help you get into closed loop.
Then I would look at that Injector global deadtime of 840 plus an additional 180 on each individual injector seems on the high side to me.
If your wideband is on the rear o2 and you have a stock front o2 sensor, don't think you need to have simulate narrowband on front o2 enabled.

 

[Myk984g63]

Okay I'll start there first. I have 550cc injectors, so the 840 should be the only global and zero out the others? Didn't realize that about the narrowband sim. I'm extremely new to tunable ecu's and turbocharged 4g63's but have had two 420a's before. The car runs very rough right now except for idle.

I haven’t looked at your tune but here are a list of injector global & deadtime starting points. Get yourself a ecmlink login and watch their demo video

[Myk984g63]

That's what I had set them to, 180 per injector right? So it should be 720 for all of them, correct?

TK's9d2TSi, I am trying to do the first tune on it since the ecu install and can't get it to run stable. There's no one here in town familiar with ECMlink so I am on my own unfortunately

 

[AWD-Tony]

Load these settings. This should get it stable but it will need fine tuned. Before you start tuning, you have to make sure the car is set up properly or else you'll just have to do this all over again.

As Tks9d2tsi said above make sure everything is setup properly, or you'll be in a never ending cycle of changing your tune. I was in that position a while back and now everything is good, after fixing several leaks, getting my ISC and TPS set properly as well as making sure base timing is correct.

I also had to stray away from the recommended deadtime values. My 1220cc injectors seem to run better on -55% global fuel compared to the -63% that is reccommended. I now have perfect idle/cruise/wot with no mafcomp/fuel adjustments I'm literally 0% across the whole range with a fully built 2.3l running a 16g turbo.

Global deadtime is not the sum of all your individual injector deadtimes combined. It's basically the value that will be applied to each injector.
If you want 180 deadtime applied to each injector you would set global deadtime to 180.

The individual injector deadtimes tab is to add/subtract a value against the current global value in case you have injectors that don't use the global value. I suppose if you are using more than one brand of injectors that function on different deadtimes then you would use the individual deadtime tab to compensate those particular injector deadtimes.

From my limited experience, you generally leave individual deadtime settings alone at 0, and use the global value since you are probably using the same brand injectors and the deadtime for each injector should be relatively the same.
If you are using 4 RC 550s then you would start with about a 180 global deadtime and leave the individual injector deadtime values at 0.

Alternatively, if you have the Fuel Injector Data sheet for your injector set, it lists your injector voltage offsets, you can setup your InjBatteryAdj table based off your set fuel pressure.

Thanks guys for all the info hopefully I can get this thing running as good as it should be! I just ordered a weapon r intake manifold and that will be the last bolt on I do besides a bigger turbo later on down the road.

 

[Myk984g63]

I uploaded the settings but it still 'sputters' with any throttle pressure. I'm probably going to revert back to the 450's for now, they ran a ton better but car was still showing 20+ on the WB gauge so I thought a bigger injector would help but actually made it worse during acceleration. It REALLY sucks not having a local ECMLink tuner in my town.

 

[AWD-Tony]

Did you watch the videos and go over EVERYTHING? This is very important and should be done before any tuning. The tune I sent was only a starting point and should get the idling after everything on the car is up to par. Are the injectors new? If they’re used were they cleaned/flow tested? Post a log of it idling

Which brand of injectors?
Spark plug wires order correct?

Upgrading to a turbo bigger than your Big 16g on a stock fuel pump?

 

[Myk984g63]

I will have a upgraded FP and FPR before I upgrade the turbo. I was more or less talking about turbos that are over $500. I still need to upgrade alot of other things before that time comes. Thank you so much for pointing that out in case I wouldn't have known.

 

[Myk984g63]

Datalog for Idiling...

 

[AWD-Tony]

I looked at your profile and don't see any fuel upgrades. You're on stock pump? Get a 255...yesterday!
We can get it to idle and cruise for now.
It's better now that your O2 sensor is cycling. You put the global to 0 and left the deadtime at 180, so what injectors are on it now?
With the car FULLY warmed up,
Turn the BISS screw to get your ISC position to 30 with EVERYTHING off, fans, lights, radio, ect.
Under MAF Comp, bring the 0 & 50hz sliders down until your airflowperrev is .25

 

[Myk984g63]

Okay I'll order a 255 today. Do you have a part number or recommended place to buy it? I put the 450's back in cause the 550's ended up being junk from eBay that came with the car. And yes I changed global dead time to compensate the 450's. I will do as you've instructed and post back when done.

Rewire it so it gets full battery voltage. (Look up 2g fuel pump rewire)
eBay injectors = Russian roulette
Change the deadtime to zero then

 

[Myk984g63]

Okay. Time to rewire and order the pump! I'll post back after everything is done! Thanks a ton!!

No problem! When you make adjustment to the biss screw, turn it slowly, let it adjust and repeat.

 

[USMCGSX]

Some friendly advice if you are planning to register and smog your vehicle in CA, hang onto your stock parts.
That rewired wally 255 you are about to grab may or may not give you fuel pressure issues, some people get away with it and some don't.
When I originally upgraded to a 255 it was the High Pressure 255 and I definitely needed an AFPR.

If you don't "know a guy" for smog, you're gonna be glad you kept your stock parts.
I didn't have any issues with smog visual inspections until AFTER I unloaded all my stock parts some 10 years down the road.
That very next inspection I had to source about half my engine bay in stock parts. Don't be like me

And yes, listen to TK's9d2TSi if you put stock injectors back in, you want to change your global deadtime from 180 back down to 0.

USMCGSX yes luckily, I 'have a guy'. It took awhile but everything was good to go! Thank you for pointing that out though! Much appreciated!
