maf tuning help please

Dhp all the way

Dhp scanner was flaky for me when trying to use the analog input on my avt-852 for wideband. The WB would stop responding after a couple minutes, though the gauge was working fine.
And I use an AEM wideband so it wouldn't work with uvscan. Finally just went the egr route. Now if I could just figure how to get Table Modifier to read my wideband data.

 

[gambler87]

Yeah I was looking at that last night. How does that exactly work. I would like it to read mine as well

 

[SgtMarshal]

if you have a plx or lc-1 wideband with a serial/usb output from the gauge, then you can go into your uv scanner options and enable it. there is a maf smoothing guide that you can use your wideband data with, but I haven't used it much, so I couldn't offer any help.

Hptumers does have the ability for standalone data logging and 0 5 volt inputs

I realize this, but you either have to rig it to work with an egr wire or pay more to get the pro version. if there is a way other than these two methods, by all means, share with us on how to do it.

 

[91parkave]

You stated it's really sad hptuners doesn't have the ability. I just said it does naturally being the pro version

 

[SgtMarshal]

My point was that you have to pay extra to get that input

 

[NebTurboST5]

gotta pay to play...

I've heard rumor that the beta hp tuner software incorporates serial/usb inputs from aux sensors. if that is true, I wont need the pro version or have to run a wire to the egr to scan for wideband data with the hp tuner.

 

[91parkave]

You need pro if you want a direct input to the box otherwise use the egr or whatever wire u want and use the wide and that way. It's just as easy and you save a lot of money

 

[gambler87]

So I need some assistance again. When u guys tune for not, do u go full throttle? These tuning guides I downloaded are telling me to ease into it, but if I ease into the throttle I don't see any knock but if I floor it I see kr

 

[gambler87]

And also do I export a new mg/cyl table every time I do a maf table out of table modifier as well or no?

 

[Scottydoggs]

no on the mg/cyl table.

i mix it up, local, highway jump on it on the highway, run it from a dig. normal driving as well.

 

[gambler87]

All in one scan?

 

[Scottydoggs]

yes. drive around for a good 20 minutes.

 

[gambler87]

Oh see my scans are only like a minute long. Could that be hindering my results

 

[Scottydoggs]

lol yes. it needs to see all ranges.

put back the stock file, let the trims re learn, then take it out for a 20 minute scan.

 

[gambler87]

That's what I'm doing. It will be going back to a stock tune with Lq4 maf table

 

[Scottydoggs]

you may still have to do it 3 or more times. its hardly ever perfect the first time out.
