We will dyno when all the important work is done. The dyno is in reality for bragging rights and fine-tuning. The real work is done with road tuning and using all the ODB II sensor data. My mechanic told me today that he now realizes he has been mislead for many years as many of us have. Those people who say all they need is dyno data to tune cars such as ours are living in the past and we have been wasting our money. Keep in mind our cars are computer (OBD II Sensor) controlled, live on the street and not on the dyno and the OBD II system rules that world. How can you ignore it and say we have tuned the car properly without full use and understanding of that data. No way!
I have been enlighten to understand, that real performance is gained when you tune in the area where you daily drive/race. You can lean a motor out to get great looking numbers on a dyno but on the street, it can kill your car and your opportunity to win.
What about the fuel trims, knock sensing, timing advance, timing retard, misfiring, IAT, EGT, MAF values and the list goes on. Most if not all of this critical, data is not used or available during your average dyno-tune. Another very important note, engine management of today’s engines are time based, this means it needs time to relearn/adjust so you cannot see ASAP changes when used on a dyno.
I am very excited about what I have learned over the past couple weeks. I have invested considerable money in this venture and I will share the result with all of you, as this is another Solara first. I have also invested in a Dell Latitude laptop computer and an EASE OBDII Scanner/Data Logger
