ECMlink Okay. I’m sorry. DSMLink v3 installed. Car ran before will not now

Here is my tb. No ground strap. Will add one.

It is a mess but I’m dealing with someone’s existing mess. I will clean it up as time goes but I’m trying to get things sorted and functional. Recording a log now of cold idle. Letting it warm and then will upload. Then drive and hot idle. I made all of the changes you suggested

first one was completely set as 2g maf i think. and then the second one is driving around with 2g. and i switch because its almost undrivable with out setting it to stock

Looks like you're also missing the IPS. Without one you will have to simulate it in DSMLink.

I always recommend not looping the ports on the TP but plugging them. I can't remember which are on what side of the butterfly but if you look one that's in front of the butterfly with one on the back side it becomes an air bypass.

It also looks like your BOV is vented to atmosphere, which causes other issues.

 

[Dethh117]

Okay. So how can I rectify these things dsm god? I need help . It’s such a cool car and I just want it to be what it was meant to be

 

[steve]

For now enable simulate Idle switch from TPS on the RPM/TPS tab and cap the two ports on the tops of the TB. The BOV should be recirculated to a port on the pipe betweeen thee MAF and turbo inlet but since your MAF is changed I have no idea if the port is still there.

If you really want to restore the car to it's glory you have a lot of work ahead of you. That doesn't look like an original engine, the Intake Manifold sure isn't

I could not find anything to identify. It is a six bolt.. can you give me a list of things I need? I appreciate you

Also I have no idea how to recirc that. Is there not a way to tune for that?

 

[Justin DuBois]

The exit port on your BOV needs to be connected to a hose that returns to the intake pipe - after MAF, and before Turbo.

If you don't - every time the BOV opens, the tune will go rich - and bog.

In order to run a BOV vented to atmosphere - you would want to switch to a Speed Density setup.

 

[Dethh117]

Okay. What can I do to run speed density? Map sensor?

Okay. What can I do to run speed density? Map sensor?

You will want to study the Speed Density setup for 1G on ECM Tuning's wiki pages for background information. The input sensors you need for speed density must include a MAP sensor plumbed to the intake manifold - and an IAT - "Intake Air Temp" sensor - usually plumbed in the throttle body elbow inter-cooler piping just before the throttle body. For a 1G, it is likely you will remove the stock o2 sensor and use your wide-band o2 with the narrow band simulator in order to reduce the number of o2 inputs, allowing for the other sensors to be wired to the ECU.

I love this forum. I will keep y’all posted. There are 1g packages for speed density

Also. I keep getting the knock cl when in boost. What are some basic adjustments I can make to allieveate this to make it drivable? I would think add fuel. And I have but it is still doing it under boost

Logs, logs, logs. If you have your Wideband and map sensor working and logging, Your goal should be to adjust the MAF comp sliders at various points on the RPM scale so that you are burning at an AFR between 10-11 at WOT.

If your AFR is off everwhere, go back to the global fuel and make a change in the general direction you need to go.

Knock can come in when there are abrupt changes in timing or tune, so you have to start smoothing things out. Assuming your AFR is in the ballpark, then you adjust timing at the trouble spots. In general, you want the max timing you can get without knock at a reasonable Boost level.

 

[Dethh117]

So much to learn. I’ve posted logs. I’m not sure what information to look at I’m dumb at this I guess. So my afr is being finicky I think I need a new one
