SAFC 5 Button (old model) + Apexi Terbo Timer

[sub level]

I just install the SAFC 5 button and Apexi terbo timer, my problem is why i dont get the correct reading from the o2 reading even i adjust the safc to - setting. is there any guide line to set the safc and the timer . im using 4g93t engine still stock only with air filter apexi and feul regulator custom made (EFN) :D one more thing i want to sent my car for dyno and setting, where is the place and what is the cost$$$

Bro.. the Apexi Tampon timer is not exactly a very accurate tool to measure you AF. DO a dyno and get a good AF reading. Try GT Auto at Sunway.
