Tunning help, MAF/TPS datalogging
Ever since i installed the ported IM, it's been hard for me to tune at higher rpms from 6400-7k. I also connected the MAF input signal wire to the zt2 wideband to see whats going on with my MAF volts, also my TPS has been acting crazy at those rpms. I think i wired it up correctly, Please correct me if i'm wrong. On the SAFC2- orange wire (airflow signal input) connects to the ZT-2 blue wire (Input User1)Everything was fine before the installation of the ported IM. The volts stays at 5.0v and somtimes goes to 4.95v at, idle, regular driving and at WOT.

Look at the TPS reading, it goes crazy at higher rpms.

shit.. i just did some more searching and the orange wire is not the MAF input wire it's the illumination power. The white wire on the SAFC2 is the MAF input wire. gotta check it out again tomorrow. The TPS is still in the air dont know wtf is going on with that.

Re: Tunning help, MAF/TPS datalogging
ok this is weird. i went out for a tune today and the TPS was fine, it was between 98-100 percent. got to finally tune it the correct way.
wut i have notice is the Higher the TPS reading the more leaner the AFR is gonna be. example. My TPS was reading at 98 with a AFR of 13.1, In the following run the TPS was at 99-100 percent with a AFR of 13.6 with no change in the safc2 corrections.
