Id injector data question
I've noticed when I input injector data in, Say on a boosted car, with larger 5" intake, I have to decrease the Maf transfer function to reach my targets in Pe table. So on an 6l80 auto vehicle, this could pose problems with shift pressures. I would just redo the Virtual Tq tables, and add shift pressure and adjust shift timing in the trans section. I was told you should alter the ifr rate in the tune so that I would should increase the Maf transfer function only, not reduce it anywhere due to reducing the estimated load. Also was told you could adjust the fueling with the Pe table, and the stoich tables. My question is when I input Id's data, shouldn't it be correct data? I'd assume the 5" intake makes the need to decrease the Maf in certain parts to hit my Pe target? Thus leading to adjust Virtual tq higher than normal. What are your guys experiences with this? I'm not a fan of tuning the fuel with Pe table, or stoich tables. But having to alter my Id Ifr data seems backwards. How are you guys getting correct load when using a larger than stock intake tube diameter?
