i need help trying to figure out crome gold i cant get a good idle without the damn thing surging.

 

maybe a vacuum leak at the intake manifold?
have you changed anything aside from the bin? does the old bin fix the surge?

 

nothing changed in pro i can get the car to idle perfect within 5 min i spent about and 1 1/2 hours with gold last night no luck

 

have you tried starting a new p30 map in gold, copy all your timing and fuel tables over and set up your options in gold.. save it and try that? maybe something is being corrupted when you edit an old map in gold? not sure as I still use the free version

 

na i never converted i just started a new map in gold but thanks for the help anyway. its a bitch going form milliseconds to microseconds i tryed converting my tune before but the ---- was worse.

 

I have always had an idle surge. Sometimes its there sometimes its not. I have never figured it out. I have changed so many settings, started with different maps. It really doesn't bother me anymore. I don't know how severe yours is, mine is minor. Little surge from like 800-1100rpms, then it just evens out. I run regular crome free. I have checked for vacuum leaks to IAC and nothing. I will check to see if you find yours. Mines on a 2000 si b16a2 obd1 with ostrich.

 

i have similar problems.. are you running a 2.5 bar map sensor?

 

I have the stock map sensor.

 

i have the same set up 99 si obd1 conversion with ostrich its a bitch i can get pro to idle mint gold is all fucked

 

i disabled my o2 sensor and it idles much better now.. you could try that?
