Mod list. -I think
550 injectors.
Gen 2 MAF (hacked).
ARP head studs.
Cometic head gasket
Front mount.
All the normal goodies with all that.

Car ran before DSMLink. 3-4 injector are not making a difference when unplugged. Have spark in cylinder and plugs are soaked with unburnt gas. I can light them on fire.

I need help, the tuning scene is new to me. I have done Hondata successfully but I need help, dsm gods please.

This car came to me in PIECES. And I have brought it back from the dead. Everything was trashed. All the threads everything I need HELP I want to save it

Yes, please stop crying and post a log. That's how we are going to see how you configured DSMLink and maybe see other issues.

What else besides installing DSMLink did you change since the last time it ran?
 
Not a thing. but idk if y’all have ever seen this. I got it to not miss. The kicker is it’s only by playing with the ignition control module connector, moving it to one side or the other and then it’s fine. It is so weird. First it was having weak spark across all cylinders. Then coil 1-4 would fire. THEN it did and it all was good again. But ONLY by playing with that connector.

Kinda baffled why it’s that way now and wasn’t before DSMLink. Also. How to I post a log

A bad connection on a 30 year old car really isn't that uncommon. The 90's models have a boot that goes over the back of the connector to "waterproof" it but it doesn't work nearly as well as the 91+ connectors that have each wire sealed individually on the back side so you probably just need to replace the connector and pins.
 
Is your PTM (Power Transistor Module) bolted down to the intake manifold like intended?

Does your connector have the metal retaining clip that locks it in place?

Do you know how to get a log from DSMLink?
 
i figured it out and congratulations im a dumbass. i had the wrong maf selected. it does much better now. here is a log at ten psi.any help and wisdom is appreciated. thank you all.

If you have a hacked 2G MAF it's still wrong. It's set for a stock 1G MAF.

What are you doing with the FPS?

Earlier questions still stand.

Yes I have extra grounds ram to all of them as wells

Okay when you say FPS what are you meaning by that?

And I think I have a 1g MAF, but I’m not sure. The wires are all ram strait. So what do I do.

The connector is tight. That seemed to not be the problem I am having no issues there now. Idk what happened, the only thing I can think is I actually mounted the ECU and the damn think fired right up after. So maybe it was a grounding issue with the misfiring. At any rate this thing runs decent now.. I just need some guidance

And In response to everyone else. The misfire is gone. It has a Garret t28. Yes I know it’s crazy on a 1g but it came with the car. I’m a welder so I TIG welded some piping to make it work on the 1g.

My old turbo was shot.. I loved that thing btw. The car was a menace on the highway. I’d anyone knows someone who refurbished them I’d be interested.

Anyways. While the car was down waiting on ram link. (It ram great before. With the garret. I just could not exceed 13psi or I’d hit fuel cut.) car got parked. I went ARP on all the exhaust hardware. New gaskets and all. I’m pretty positive I have no exhaust leaks and I think there was one before.

So. What I need to know. What do y’all mean by configuration? I’m not totally stupid when it comes to tuning software Hondata is wayyyyy different tho. But ECMink is amazing with the capability. I just don’t understand it all.

And if someone can help me just get this car to run 18-20psi happily I’d be satisfied. It’s going under for a rebuild my dad and I are doing next winter. I just want to enjoy it a little bit this summer. I have always wanted an Eclipse and this thing came to me in pieces. Totally ducked. So just be patient with me. I’m new to this but I learn quick and was a shop tech.

FPS (Fuel Pressure Solenoid)

You must be logged in to view this image or video.


I suspect you should disable user-defined settings here and let the factory setting control the FPS.

1G MAF (Mass Airflow Sensor)

You must be logged in to view this image or video.


2G MAF

You must be logged in to view this image or video.


So which do you have?

When we talk about DSMLink configuration we mean the settings in DSMLink to configure it for your car. Things like telling it The idle speed, what sort of fuel injectors you have, the MAF type, how to use the FPS, which sensors are connected where and what to ignore.

For example you shouldn't be locking the inputs of anything unless you have connected some other sensor to that input to the ECU. Typically these would be locked on a car that is running speed density and your not.

I think a T28 at 20lbs would be a hairdryer (I could also be WRONG) but maybe those little units can make 20 lbs and USE 20 lbs.

Contact Justin Whitesell - @JusMX141 is our resident turbo remanufacturer and is very good at what he does. Contact him if you need rebuild services.

So what psi is solid to run a garret big t28 at?

Okay so unlock all of that? Holy hell thank you man! And a 2g maf for sure

Dude. Your awesome I will apply all of this tomorrow

It is such a small turbo, and I have never ran one, so that is why I stated I could be wrong. Even pushing a little 14b to 20 lbs seemed to be just pushing it too far in my case so I have switched to bigger framed units. A bastard 20g would work really well at 20 lbs though. I have ran one of those before I went to something more for my taste (but not necessarily anyone elses). I would bet someone with more experience with a T28 can give better insight as to its performance.

@1990TSIAWDTALON I had mine set to either 17 or 18 psi and the bearings lasted 18 months before the whole thing blew to the point where the wheels were damaged and unrebuildable. It depends on how long you want the thing to last. And even then, you're still limited by the stock turbine housing. Needless to say I don't recommend them.
 
Back to the original issue fellows.
Carry on.
 
Will be posting a log in 20 minutes. One running 2g maf. One not. And one just cruising around the neighbor hood on about 14 psi at my guage. Kinda bouncing between the two settings. And playing with fuel.

2g maf

1g/2g playing with some stuff too. need help LOL

I didn't look at the 1G MAF log since you said you have a 2G MAF. At some point you'll have to look inside it and see if it's unmolested or not.. It's better if it's untouched.

There is no reason the car shouldn't be able to idle at stock RPMs so get it to run as close to stock before trying to do anything else.

To that end set the idle speed back to 750 and enable idle switch operation.

I want to see if the IPS works and if you can get the idle down so you not masking anything. I also want to see if you can enter closed loop at idle and that the O2 will cycle normally. Once it does you can look at the fuel trims (you have too add them to the captured data along with ISC steps and battery voltage, etc.) and see if you need to get the airflow/rev to the standard.

You make also want to enable hot start enrichment. The factory software raises thee fuel pressure on hot starts to avoid vapor lock. That's what the FPS is for.

Once you get the basics 100% dialed in you can start to actually tune using the direct access maps for AFR and timing.

Alright so get everything else dialed in and only run it on 2g maf. Gotcha. When the idle is low it just dies randomly and it’s been like that since I put it back together. But thank you I will reapply and re upload
 
And this is one way to figure out why it does that. Like I said masking the problem.
I suspect from your others logs that your IPS isn't working. You do still have the 90 TB on the car, right? It's also important that the ground strap is present and attached to the bolt that holds the TB elbow and TB on and the the intake manifold has it's ground strap to the firewall attached.
