What size injectors?

[TDCRacing]

i am not saying at all you are wrong but the info you gave me(or the numbers) are to low to enter into my tuner for the ifr table....this method of doing it is all over the place...and if i do it this way i would be raising the ifr numbers



How do I calculate the perfect IFR for my car?
There is no ONE perfect table for all cars, but here are a few tips... Stock injectors? STOCK IFR! You have a GTP and are moving from 36 to 42.5 injectors? Math is your friend... divide your old injector size by the new injector size to get the variance. For example: 36 / 42.5 = 0.847. So... your new IFR table shall be 84.7% of the old table (highlight all cells in the IFR table, right-click, select CUSTOM, click on PERCENT, enter 84.7, click ok... Voila, your new IFR table near perfectly matched in a few seconds!). It may or may not need to be touched up. It depends on your car.

Eddie is using Metric, you are using imperial. To use his figures you need to change that table to metric temporarily

another example...in my tuner for the ifr table it says....max-infinity...min-7.9...it seems by the example above that infinity...or raising the numbers (since there is no limit to going higher) would mean bigger injectors...i just saw that bill said our values are different....he said to try and match the values and we should be good...he said ur values are g/sec and mine are lb/hr...how do i change this?

i knew it was something simple...how do i change the editor between metric and imperial? i know how to do it for the scanner.

i found it

BTW changing units is a very simple procedure & is covered in the demo http://www.thetuningdoctor.com/HPTun...Unitchange.swf that is located in our demos section of the forum http://www.hptuners.com/forum/showthread.php?t=5058

needing to upgrade the injectors soon since im seeing duty cycle% in the lower 80's...plus thinking of dropping to at least a 2.8 and an xp cam.
so....42.5 or 60's?

What are your IPW's? I think they max out at 21ms.
