need help tunning (newbie)

[apocalypsio]

Ok so firstly I just installed ecm link on my car but runs worst than with stock ecu (even thought on both they don't idle right). I have a 2g (98) talon with 6 bolt swap and aeromotive compact afpr (put fuel pressure at 37 since the 1gen engines run that) (stock 2g injectors), I also have a walbro 255lph fuel pump .

When I finally got the car running it would boost fine, but idles not to stable and runs kinda rich I can always smell the gas (I still have stock maf but the way and was tested) .I did vacum leak test and I only have a small leak at the throttle body wich my mecanic said was normal since my car is old.

Long story short with ecm link installed my car runs super rich (like I'm talking blue smoke on idle) and doesnt boost right , its like the fuel cuts .

Here is the log any help is appreciated I'm new at tuning and have looked around in forum for similar threads alredy but nothing that really helps me out so far.

Is everything set to stock though? You sure nothing has been messed with on ECMlink? Like changed fuel levels???? When I installed dsmlink my car didn't do anything until I started messing with it.

I just touched the tps to see what it would do but reset it after. Well to be honest I'm wondering If I put the right fuel pressure on the afpr and or the pressure is right on the program because the afper is at 37 but in ecm link its at 42.6 , I don,t know if that a problem.

blue smoke is oil not gas burning. And if you have a vacvum leal at the tb your comp. will see at as unmetered air and will afjudt your stft yo compinsate for the lean condition...adds more fuel. Fix the vaccum leak.

Your front O2 isn't cycling at all. Your not logging fuel trims so I can't see if the ECU is dumping fuel to get a reaction from the O2 sensor or not. From the one throttle blip you did the O2 reacted so it's functioning, but at idle is nearly flat dead for some reason. Are you simulating narrowband with a wideband? Make sure narrowband sim is off if you aren't using it. Also, did you buy Link used?

I would suggest checking the grounds at the ECU, checking the front O2 wire at the ECU, and make sure all the fuel maps are stock. You can go into direct access, select a table, and hit the curved arrow at the top right hand side to revert values back to stock. Here's a pinout of the ECU. Pin 76 and 92 are the ones you should pay special attention to.

Thanks for your quick replies, no I'm not simulating anything nor do I have a wideband installed. I will check the grounds tomorrow thought and see if everything on the sensor is right also. Also yeah I'm gonna get rid of my leak on the tb you're right it should have been one of my first things to fix while I,m at it I'll install the 1g tb and change seals and what not.

(sorry forgot to mention I bought it brand new from ecm tuning its the v3 complete)

OP - You need to spend some time reading and watching the demos, so you understand the basics of getting ECMLink set up properly.

And, it looks like your front O2 sensor is dead as Wes_393 mentioned.
