[mikeymike1]

ok guys i just bought my first 1g and i think i got in way over my head.....well first off the car has a 3.5 gm maf 16g turbo fmic ecm link v3 stock injectors....ok the car runs it dont idle worth a damn it bounces up and down..i checked the timing using the ecm link by clicking the box and it says 5. ok that sounds good right? i made sure that the tps was set...i changed the front o2 sensor because when i checked it out the heater side was bad "shouldnt have any thing with the sensor reading right" ?? did all that and i havent got any where..car dont go into cloosed loop? i have one dtc which is for the knock sensor..i dont know how to save a log from cold start till warm up to let some one take a look and tell me what is going on...i dont have the user name an password for ecm link forum yet i have to wait till this weekend to get out to my fathers house to get the number off the chip and send it into thomas dorris at ecm link..but if some one could ### point me in the right direction would be awesome...

Start with a boost leak test.

When you ground the timing through ecm link it automatically assumes that you have the timing correct! You need to ground it through link and then use a timing light to check if your timing is correct. Pull of the cam gear cover hook up the timing light crank the car until it runs. Ground the terminal through link and adjust the Cam Angle Sensor as needed until your timing marks line up on the cam gears. With the car not running and the key in the on position have link running. Log your TPS voltage, it should read .48 to .52 volts that's the green area you want. if it does not read that then adust your TPS. Also a tip to help smooth out your idle maybe simulate your ISC position if you dont have it set at 30 which can be a pain to get there then just simulate it. If you have some other questions I'm sure more people will help out including myself. I have only been running link V-3lite for 2 months so I am new myself but am 100% about what I have told you above.

I'm pretty sure tps volts should be .63 volts with the throttle closed. here's a link for you to check out. YouTube - Tuning 102 - Idle Tuning

I just double checked the Haynes manual I have in hand and it says .48 to .52 volts this could be incorrect or a typo in the manual itself.

Is everything setup in link for the gm maf? Post a quick log car doesnt have to be running.
