Are you in the screen for dic / hud or calculated PID's?

The format I posted, i.e. pid(1008)/60000 * pid(10) / 2 * 100

is what you should use in the calculated PID section, then use that PID on one of the pages for DIC or HUD. Spaces or not shouldn't really matter

This shows how the setup basically works. It's for a wideband but the steps are the same, except use this formula instead of the one in the pictures that was for a wideband

If you want the other bank to display, you would have to substitute 1008 to 1009.

That formula appears correct. I'm not going to be the redneck revving up his corvette in the drive way but at idle it matches HP tuners

So I literally copied and pasted what you used (changed to the PID numbers) but all it shows inthe DIC is the actual formula...??

Probably should start with this.. You're putting the formula in the wrong place I do believe.

Thanks... I'll try that tonight.

I was going into the "custom" section, when you select the page. Then going under the "advanced" area and entering the formula.

Yeah that's the wrong place

You have to create an injector duty cycle PID first by going under "calculation PID's". That's where you'll want to enter the formula I posted yesterday along with the number of decimal places, units (%), etc.

Once it's created then you go under DIC or HUD, advanced, and then use that new PID. I can post some screenshots if you need help

I tested it this morning and the formula I posted earlier did seem to work correctly

I used it and works. Under "calculation Pid's" I have one using 1008 and one using 1009 (both banks). No decimals. On the HUD in advanced I added the %. At first, I put the injector pulse with next to that reading and it seemed inline.

Thanks for everyone's help!

You could always average inj PW for bank 1 & 2 if you really wanted to. Either way they're going to very close to the same at WOT anyways

Yes, your right. 1008 seems to be the same or 1-2% more duty cycle. Most be air flow or sensor variance.

Fuel trims are probably a little higher on whatever bank is reading higher

OK, so tried it and let it idle.. Shows 2.2 (ish) at idle. LS9 injectors with heartbeat blower and cam.

Havent driven the car to see but that's what I show using the formula above. Quick little rev, the numbers shows 8~9ish.

Sound about right?

That's about right. Mines about 1-2% at idle but I'm running ID1000's and e85

Since you all are already on the subject, does your odometer function in dashlogic work? I am using the pre mapped pid for odometer, and all I get is 0.0 mi. I'm assuming I need to make a new pid based on speed sensor input.
