"1995 Eagle Talon TSI AWD 5 SPD" (stock injectors & Turbo)

Well it seem's like i'm running blind into walls with my project.

Now I'm hitting fuel cut at about 4500-5000 rpm

Ok here is my current setup. Dejon turbo intake with no vacuum ports, 3"turbo back exaust, Greddy type rs blow off valve/ open air blow off, 3" GM MAF sensor/ after blow off valve, 1g MAF translator, Egr block off plate, Evap canister removed, Ballance shaft removel kit, ARP head studs, and manual boost controler.

Well right now on my MAF translator, I have my AUX=4 Base=2 Idle=0 mid=0 wdt=0
Mode I have #1 on and 2-4 off. It's idleing a little bit off to but not that bad.


Some one please help I do not have a data logger or any read out device on my car at this time. I just ordered a Greddy E-manigment system but do not have it as of yet. So I'm really in the dark and do not want to hurt my car. Is there some one that my have tuning advice for my MAF-T settings?

I'm still new at tuning and do not really know how to set my car up. " Blow off valve setting, MAF-T settings, and Boost settings.

Please help. :confused::beatentodeath:
 
I would advise against going to 5k RPMs again until you know what your fuel trims are looking like. Without a wideband oxygen sensor or any kind of logger you're running a HUGE risk of blowing your engine.

As for the MAFT settings, each car will be slightly different. Those difference become significant when you start hitting higher RPMs and running completely lean will blow your engine.

There is no magic number setting that you could put in without all the other required information, such as fuel ratios, knock, boost pressures, injector cycles, etc.
 
Thank you. I don't plan on running the car again untell I have every bit of information I can gather. I really don't want to blow this engine. I should be able to get all the info out of a Greddy E-manigement systm right?
 
To use the emanage, you need to get the support tool software and use it on a laptop. Also make sure to get the timing harness so you can control timing. Then get a logger since emanage will not log knock and fuel trims like you need.

I actually went out last night and helped tune my brothers timing map. We got it holding a good 20-22* at 32psi spike on the 16g on some e85 with zero knock. The emanage tunes real nice.

On the maf-t set boost to stock and all settings to stock 450's.
 
Why emanage when you can go dsmlink? It's proven over and over again.
No wideband and trying to tune = no no
Do a boost leak test first and formost.
How much boost? You really can't do much on stock injectors.
 
Emanage is way cheaper and IMO has better afr/timing control. Not just my opinion, even Jack at Jackstransmissions agreed that part of the tuning is better than link. Now when v3 comes out that will be a different story.

Good thing about emanage is you can get injector compensation, timing control and fuel control for under $300 if you look for it right.

Your right. Do a boost leak test first! If you were running fine and did not change anything then out of no where your having problems like this you need to check for leaks. Do you have any gauges at all (boost, a/f)? Do you have a boost controller? If this is your daily driver I would say to back off the boost to as low as you can and keep your foot out of it till you find your problem.

Sorry if I sound dumb but I'm still new at all of this, but how would be a safe way to do a boost leak test? I have a boost gauge and a oil presure gauge. I don't have a A/F gauge yet but soon (in the mail). I do have a manual boost controler but its at the lowest setting.
 
You need to get a rubber coupler and block one side off with a pcv cap. Then drill a hole and install a bike tire valve so you can pressurize the turbo. Install the boost leak tester on the turbo and pressurize to 25psi or if you run higher boost go to that.

The a/f gauge is useless and just for looks. You really cant do anything with it. If I was you I would look into a wbo2 for tuning like the AEM EUGO.
 
Thanks for the help. Is there a link with some pic's on how to do it? That might give me some more insight as too doing this boost leak test. I also orderd a ETG gauge, I read about tapping into the exaust manifold on the #1 cylinder and it should help with A/F readings....? I hope this is true because now I think I just wasted $50.00 on a A/F gage, and I hope I didn't wast $80.00 on a Exaust temp gauge.
 
I think DSMlink is better than emanage but I think burning your own chips is > DSMlink. You get much more control over timing and fuel maps. It doesn't make you feel like a 6th grader moving sliders to adjust fuel/timing/airflow. You are actually in there changing the code. Plus you don't have to wait for a new version to come out to support anything that is currently available. You can take the code from DS-Map for SD and add a few things here and there and have a pretty well performing system for cheap. Plus you get a feeling of self sufficientness when you can control your own stuff.

I'm not saying DSMlink is bad. I'm just trying to say that it's the most comprehensive tuning tool available. And what I mean by comprehensive is that it takes a logger/EMS tool and puts it into a GUI interface that a 6th grader or maybe younger could use and understand.
 
well, keep in mind that 95% of the people out there are not those type of guys are going to screw around with code and burning their own chips. Simply because they don't know how.

Yep that's why ECMtuning implemented the GUI DSMlink with the sliders.

I wouldn't consider DSMLink just moving sliders around like 6th graders.

How do you adjust your timing/fuel/MAF compensation/VE table in DSMlink??

Tuning the car is far beyond just moving few things around.

Yes you are right it is. That's why I think with the money you spend for DSMlink you should be able to do the things I can do with the fuel/timing tables. I think there should be a toggle for people that want the ease of sliders and others that actually want to change the fuel table not just add or subtract from it. If it could do both then I might even think about it. Maybe V3 will be better...

Fastest DSM out there are powered by DSMLink, ever wonder why?

Scroll through the list of 1/4 mile times here on this website and you will find that most of the fastest (top 20) use AEM EMS or Haltech.

I do not mock you for using something else as a tuning device, but I am sure there are enough guys on this forum who can vouch that DSMLink is by far the best EM you can get for the money and for your DSM.

Yea there are a lot of guys that run DSMlink of course they are going to vouch for it. I'm just letting everyone know that there are other options out there for the stock EPROM ecu.
