42.5# injector tables for DHP PT

[Sabrewings]

Anyone know where I can get the IFR tables for 42.5# injectors for the DHP PT. The tables posted in the sticky are for the HPT and the DHP PT uses different table units.

What size injectors do you have on now? (N/A vs. S/C, might be 33 or 36)
Either way i just pulled this up from the tuner guide so you should be covered either way:

If changing from 36 to 42.5 injectors divide your old injector size by the new injector size to get the variance. For example: 36 / 42.5 = 0.847. So the 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, the new IFR table is now near perfectly matched).

I am using a stock L67 file, so whatever they have stock. 84.7%? Makes sense. The DHP PT table uses a value that says how many mSec to get a full gram. So, bigger injectors, the less mSec to get a gram. Thanks.

working....stand by

This is what a stock 99 gtp will look like when altering for 42.5# inj.

Stock 36# inj. table:

Altered for 42.5# inj. (36/42.5=.847) Highlight all cells, right click custom>PERCENT>84.7

Yup, that's it..........

Here's what mine came out to. This is a stock 04 SS (L67) file. They may have different stock injectors than 97-03 do. New data on the left, stock data on the right:

I edited the other post so people won't get confused, thats good that you didnt just swap the table over then! lol I'll have to take another look at my tables in the .bins I have. Im going to be switching to #65 inj. soon, dont want to take any chances.

Okay, looking at your stock data the 04-05 L67s have slightly better flowing injectors. So I'll copy the data you came up with.

You sure that the stock 99 injectors aren't 33 and the 04-05 L67s aren't the 36?

Im not on my tuning laptop right now, I just pulled that from the tuner notebook online, thats why when i get on my tuning laptop i have to doublecheck my files to look at all the differences.

The 04+ should have been 33# EV6 inj.
They also say that the 97-03 used 33# EV1 inj. but are also known as 36# inj. Im at a loss, tired and goin to bed... lol

Hmm... well I was just browsing on the PT forums and the stock data in the picture I posted above is indeed stock L67 data for the 33# (aka 36#) injectors. So the table I created is correct, according to Eddie.

Thanks anyway.

Injectors are generally rated at 42.5 PSI, but our fuel system runs higher pressure than that. I think people call them 36 lb injectors because that's what they flow on the L67, but they're actually 33 lb injectors at the standard 42.5 PSI.

So what are 04 stock injectors considered when doing these calculations? Also, the Ford green-top injectors are just 42#, not 42.5#, right?
