Fuel Filter Minder countdown strangeness

[Cougar281]

The Fuel Filte rminder is counting down at a rate of about 1% every 1/10th mile.... Anyone ever seen this happen? The relevant table in the tune is stock....

sounds like you get about 10 miles out of a fuel filter... that's gunna be spendy in the long run, maybe you should have bought a ford

J/k

That's really odd, and the minder table in the tune is stock? super weird! What about the FPR flow rate tables? stock?

[Cougar281]

Yeah, all stock. Only things I've changed is killed the IAH & EGR DTC's, vane tables to give it the "rumble" idle & turbo brake, and speedometer tables to correct the speedometer for my 265's.

[bballer182]

just for shits and gigs, what if you change the speedo tables back to stock? whats the IAH?

I assume this is your LBZ?

I guess I could try setting the spedo to stock.... IAH is Intake Air Heater.

Yep, this is my 04 LBZ .

[bballer182]

Oh yeah the LLZ. i think that might be part of the problem too!

Well, in theory, it shouldn't be since the FF minder is controlled by the ECM, and I have all LBZ stuff under the hood....

[Cougar281]

Well, I don't think that the LBZ swap is the issue... I swapped in another ECM and reset the FF minder, and it dropped to 99% somewhat quick, but in the 1 or 2 miles I drove it, didn't go any lower.... I'll drive it a bit more to confirm....

Edit: Now I'm pretty sure it's something in the ECM. I just put about 20 miles on it with the second ECM and it hasn't left 99%... Anyone have any thoughts? Could it be some remnant left over from the flashes with the APP voltages changed that borked the ECM?

[bballer182]

have you full flashed back to 100% stock the first ECM to see if that fixes it?

[Cougar281]

Not yet.... That next tonight (Assuming the ECM survived it's fall.... TTM... Don't ask).... After the last few FUBARs I only did cal flashes which fixed the ECM and got it working... maybe something's still borked in there...
