ECMlink 99 GSX Idle problem

[slam816]

just installed 16g w/ 2g install kit, fp mani, jm fab o2 housing, innovate lc1, act2600 and link v3.
car starts fine but will idle high and after driving it will surge for a minute.
spent 3 days messing around myself then took it to the shop.(not performance shop)
fixed vacuum leaks and isc test fine.. according to the shop.
next they want to clean the throttle body but i dont think there heading in the right direction so i brought it home.
im wondering if being as how the ecu is from a 97 if that could be my problem?
i didnt know what to log but i hope the log helps.
my plan for tomoro is to reinstall the stock front o2 and stock ecu and see if the problem persists.

Check and make sure your maf is plugged all the way in and the clip is clean on the inside. That's just a suggestion though, I can't look at the log since I'm on my phone but did you buy link used? If so did you make the previous tune was reset to factory?

I wasn't aware that link v3 worked with 97ecu, I thought it had to be an EPROM (95 or older) so 97 would run off stock settings, not link, and won't know about bigger injectors. Could also be your throttle cable is too tight, do some adjusting and follow the fast idle link posted above.

Thats sweet! Its been so long since I looked at ecm's site for products that i had no idea! Now I know I can send my stock 97 ecu in and have a backup, thanx! When I bought my V3, 95 or older eprom was the only option. They could convert 95 or older ecu's to an eprom but not the 97 and up.

your tps is way off, should only be about .31v. looks like your airflow is off because your front o2 isn't oscillating properly and you probably have a huge boost leak.

 

[slam816]

ya had some boost leaks.. now fixed.
and base idle was off.. shop "fixed" that.
idles quite a bit more stable. still sometimes wants to idle a bit high 1200, its set fr 900.
when you come off the throttle is it normal for the afrs to go so lean?

 

[Dert]

Yes it's normal for afr's to go lean after letting off throttle
