Default Uberdata 1.7 Questions.

Sup im as new as they get when it comes to tuning but ive been following the faq on pgmfi.org.
I am messing with uberdata to get an idea of how to tune and what not. Im using the p75-import-only.bin

1) OK on the MISC. tab, under the IACV, The slider is set to 0, what does that value represent in RPMs?

2) In the FAQ it says use the formula (240/NIS)*100 + 5-10% i assume that means (240/450)X100 if i were using 450cc injectors. So when adjusting fuel modifiers for, lets say the TPS Enrich would i put in (53.33+ (5-10% of 53.33)) or would i put in (53.33 + (5 to 10)? The FAQ says set to 65% if using 450's but i just want to carify.

3) To scale the fuel maps it says i need to select all the cells and then re-scale them for larger injectors and it has the ghetto way of doing it using the aforementioned formula.however, i dont want to do that because it states that larger injectors dont flow as much as lower pulse widths. Should i just go ahead and scale all the cells like that then tune each individual cell?

Thanks Thats all for now.

When you go to the misc tab, you can scale for larger injectors, and that will scale the WHOLE fuel map for you.

Last time I checked the IACV slider is in percentage, like a duty cycle. It doesn't have anything to do with RPM really.

For fuel modifiers I would use somewhere around 60.

yeah i was gonna use 61 cause i figre that puts it between 7-8%, also i figured out how the cells work and relat to each other and how to enter information on them. also figured out that tha iacv is a percentage and the more positive the lower the idle. however, i still need to scale the fuel maps. so do i select all the cells and then put 53 in the multiplier and then hit apply and then 8 in the additiona nd hit apply?
