Some of the things I see are that with a more modified motor, especially bigger strokers and or using power-adders, cylinder pressure is increased. With that, the temp. will increase some at the heads (not the CTS/intake typical scan data). This is controlled in several ways, because you're going to be making more tq./power in those ranges, timing doesn't need to be that tweaky anymore to get it have response/power etc. All hacks/bins have various add-ons tables for comping fueling, IAC, etc.(some for timing) based on temps. to further control changes that occur from motor/cyl. temps. When these are changed, this also aids in controlling temps. Additionally if it sequential, the fueling can also be tuned better. Obviously this doesn't help much if trying lug the car in 6th at very low speeds etc. |
