Hey guys, Im mainly a GM user when it comes to HPTuners and have read some of the Mopar PCMs are a little different in the logic of making adjustments. Is there anywhere that kinda has a guide on how...

Thats the logic I use when doing any 3800 tuning. The problem with my wideband is not a histogram issue or anything as I have all that done and fine. The probelm I am having is in my connections...

507,

Thats kind off the approach I have been taking but the issue with trying the MAF-AFR Error is my WB is unable to actually log right now. And, even if it could, the WB and the fuel trims would...

Getting back into trying some new stuff and am curious about something.

When I first changed to e85 I did all my tuning pretty much in open loop (never was able to log my WB so just eye balled the...

Do you mean just at WOT or in general...?

Hey guys, quick question...

I cant find were I saw it but I remember reading our narrowbands will ALWAYS trim to the 14.7 afr even if we change it to something else. I was gonna lean up a little...

Indy,

IIRC, also remember a wideband is less accurate in lower rpms so fuel trims and AFRs between the narrowband/wideband might be a little off at cruise/idle rpms. So, its usually a good idea to...

1. So youre saying all the tables should be the same number? or just scaled the opposite way?
2. I realize what youre saying, but if I stay in OL and just scale the maf via the wideband (which...

1. What table are you looking at for the IFR spike? Flow Rate vs KPA?

2. Originally I changed the stoich trying to run leaner on e85 only to find that changing the stoich does nothing as the trims...

meant to add on the injectors that seems to be working on our cars is just take whatever injector you are running and subtract 30% (60x.3=18, 60-18=42)....

That 50* timing is also with a gas AFR of ~16.2 and still doesn knock... would try to go higher if the pcm would let me...

Yes I have my wideband (still finishing up the maf smoothing) and my...

see how paranoid I was??? lol

Any advice or constructive criticism would be great ( be gentle Im still considered a noob ) Im still dialing in my WOT fueling but other than that I haven seen anything wrong with AFR, KR or any of...

last I knew (and played with) was that you cant change the command AFR just by changing the "command". The only way to control the AFR is to be in open loop (on the gtps anyway)...

so you would...

hopefully Paul or someone who has messed with DHP can chime in here... sorry I cannot help as I would guess the TCC would be the solution...

Thanks man!!! here is my current setup (dont have performance shift) and ill try to hunt down a stock 02 one for you too...

1.84...

anybody got a tuning "how to" for the 4t65e? been kinda playing with others tunes a little but and am pretty good with engine tuning and wanna move on to knowing more about these transmissions...
...

Ive been looking around for a while on the concept of switching to Lambda after going to e85...

my only problem is... even after reading what ive found... im still lost...

can anyone please try...

^^^ how are your wires ran?

ill keep playing with this a little... keeps coming up "unsupported"... how do I tell the histogram to read off my wideband?

been searching for a few hours now with no luck (except V8s) on a way to make a histogram that will display % error of my wideband readings to maf hz...

that way I can copy/paste special the...

that would be awesome if he found out he got a car with a TEP tranny in it and didn know it!

what other mods do you have besides the zex kit? Im curious why your shifting so high and also why your WB is showing so rich at WOT...

scans look pretty solid though keep it up!
