Tuning Time
Alright everyone, its that time to start tuning. Now i have spoken to some of you about tuning on pms, so now i am making a thread in hopes to draw additional help and to keep this as a thread for future reference.
Current setup:
- 5.5 lb pulley
- jim's fuel mod
- 190 walbro fuel pump
- 330 injectors (correct me if i'm wrong on size but its the one most people are using, the n/a supra injectors)
- jpp header/y-pipe
- apexi WS exhaust
- k&n drop in filter
- safc II
- Innovate LM-2 wideband
some issues i'm having:
1. no matter what i do on the fuel correction for the low map the AFR seems to stay right around 14.7. I tried increasing the correction % on the SAFC to see if the AFR changed at idle or even while holding a low rpm (i.e. 2k). The AFR jus seems to change then steady back out near 14.7. could there be something wrong or is this normal?
2. when driving if i let off the gas and leave the car in gear to let the engine slow me down the AFR shows crazy numbers like 20 all the way up 100 sometimes. the car seems to be responding like normal though. is this an issue?
3. has anybody used the lm-2 on their solara/camry. if so did u guys use the obd-2 cable to read rpm and tps?
I have plenty more questions to come but those are the first ones. Please only post useful comments as i know some will tell me to go to a dyno ect ect. I would hope this could be a good starting point thread for people who want to learn how to street tune themselves.
Thank you,
Michael
