ECMlink 2.4L starting points?

[rdeis]

Hey, all! I’ve just acquired ECMLink and am starting the learning curve. The car is a 1Gb with a 2.4L, 16G, 264 Kelford Cams and 660 dense injectors. Stock MAF and A/F for now- sensors and injectors will go bigger soon enough.

I have ECMLink installed and connected, all stock settings except for the injectors and TPS adjustment and it starts and idles, wahoo!

Are there any primers, quick tips, or gotchas, for running the 2.4 with a MAF? I’m not ready to go to speed density yet, I want to learn it a little at a time. Make everything right, turn up the boost a little, add upgrade a part, repeat!

I’ll take any suggestions for good training courses or etc as well- but really looking for really early basics that the 2.4 will ask of me.

Thanks!

There are some stickied threads here that will get you started, so go through those and get your base fuel settings loaded into ecmlink, assign your sensors, etc and then do a log and post it up. If you're on MAF you shouldn't need to specify that you're 2.4L, that will be necessary if you move to SD.

Thanks! I’m working through the MAF compensation now. With the car warm in good weather it seems pretty smooth. I’m rather amazed at how easily I got from install to drivable!

This morning in the cold and foggy I had some terrible head-jerking performance, but once the car was warm and the weather got better it was back to its old self.

I’m wondering if the open loop settings are way off and the jerks came from switching between open/closed when the engine was cold?

I’ve also noticed new trouble with hot starts- I recently replaced the fuel pump and check valve and hot start problems vanished, but now they are back. Open loop again?

Only way we can tell is if you can post a log up. You can post the .elg file just like uploading a photo

Will do! I just discovered the load factor correction and set it to 83% per the ECM link docs. I’ll capture new logs in the morning and upload. I’m logging 20 some values, is there any reason to filter that to critical things?

One log for a drive around the neighborhood and another for a long pull up the local hill, yes?

No you want to log as much as possible, you can remove some of the ugliness in the graph by simply clicking on the colored box next to the logged value. It will take that values line out of the graph so you can have the critical things up there
