Well I changed the air intake pipe to the last picture posted. I did a MAF error run and corrected it by percent half. Still didn't hand smooth it, or the VE table.
Seems like it runs more on the...
I'm pretty sure thats for a card type maf, thats all I can find info on.
That filter was designed to fit on the end of the maf. Not that it makes it correct but thats what Spectre says.
I have...
Well I got rid of the bend since I posted that picture, haven't driven it yet rrrrrrrrrrrrrrr deleted
So is 4 inch too big?
This is the maf. Fits perfect but I'm not so sure the bend is ideal for function. Could this have something to do with the problem?
This is a new filter, with the smaller filter I had on it I...
So thats the VE and/or the MAF airflow?
It seems the VE is a lot easier to get right than the MAF. When I tune the MAF it seems like it doesn't make much of a difference. Like I can tune the MAF...
Yes, it is too rich. Once it hits the lower 12's and goes into the 11's the airmass goes from .9's to 1.0.
Seems like I can get the rest of the tune dialed in pretty good except for the WOT PE.
...
I always tune my own stuff, even the OBD 1 stuff.
My local track closed down for good, a new shop opened up. I took it there hoping the guy could clean up the tune I did but apparently not. I...
I did hit 1.00 in one scan file. It runs fine, just a little rich up top, seems to be holding it back from the feel of it.
Would you say my cyl airmas is normal? I'm at very low altitude if that matters, weather underground says 20 feet elevaton right now.
Does this look like any kind of progress?
I updated the injector data, and the cylinder volume. The cylinder volume changed the ve table so I manually changed some high numbers.
Then I did one...
If you compare mine to mjc79's there are some minor differences.
I don't how significant they are but it is what I should be running.
I wasn't arguing I was confused too lol. Thanks for that info.
Thanks!
I have seen that data before, mine is slightly different. Yet I do have some flex fuel tune files that use the data I'm running. I need to figure out how mine is different. Or just use...
So what does this have to do with my first post?
I took injectors, rails, regulator, off an L59 and used it's injector data in my tune.
How does your information apply to this?
Thanks for...
Now I'm confused.
I HAVE 25326903 injectors so why would I say any other number?
In fact I have several sets of those.
And I have a pile of regulators that read 45 or so with the vacuum...
I've actually researched this a lot. Especially looking at a lot of trucks in several junkyards. The L59 with vacuum referenced FPR's use 25326903 injectors at 50 psi, and the L59's that use...
Non flex fuel.
It has 50-52 psi with the vacuum hose disconnected, even under load. And I did a pressure hold test on the system and it held within 2 psi for maybe 40 minutes until I called it...
It's actually a 6.1 come to think of it, it's .035 short of 6.2. So it's a 6.0 bored .030 Sorry about that.
Injectors are 25326903 They are rated at 33 pounds with the flex fuel rail that has the...
It has a NBSS intake, 92mm tb, 243 heads, iron Gen 4 block bored .030, shorty headers, Dual 2 1/2" exhaust, 4" aftermarket air intake, summit 8706 cam, 33 pound flex fuel injectors running at 50 psi...
Tune file attached

Have a 6.2 liter in a 2003 silverado, has a summit 8706 cam and an aftermarket air intake. Pretty much all.
Tuner says it's hitting .90 up to 1.00 in the upper rpm ranges.
What exactly does...

Problem really solved this time.
Problem: Programming (tuning) a Dodge Police vehicle TCM changes the way the Autostick works. You can read it, and write the same read back into it and it's gone. I...
