Are you able to disable decel fueling?

Bring one back. :)

I don't want to :doh: on this topic. However, just wanted to bring some awareness to the necessity of having support for the latest DCJR vehicles.

We all know that...

exhaust mounted?? As in clamped down to the tailpipe?

If so then yes your readings are not accurate to what is being displayed in your logs.

I believe the rule of thumb (how many thumbs do we...

Please post your logs and tune so folks on here can offer any help.

Another vote for id's here ... Haven't heard a single issue with their data that's included with the injectors. Can't say the same thing about the other injectors out there.... How many "I need data...

You're not going to make any real power with that rich of an afr. Get it to hover around 11.5 and u should be fine.

However I do remember reading a long time ago where folks would vary their afr...

Welcome....

There are some stickies and key threads that can help you. There are also a few manuals that are tailored for beginners. Good luck and get used to sleepless nights starting at tables....

Yeah, I've been using google to search on here. I get better results. Obviously this may have nothing to do with hptuners themselves... I just use a regular browser search like bing or google.

Is there a way to add certain 3 character "words" such as MAF, RAF, etc? These are terms that are used regularly.

I tried searching for maf only with quotations, with a dash, etc.... and couldn't...

EDIT: NEVERMIND! I selected the proper pid in the scanner. :banghead:


Hey....

Quick ?? stock 2000 ls1 + mp112, stock map sensor.

The kpa reading in the Table Display is different than the...

Right... It's really close. :)

Thanks!

It's a sample!!!! Geesh!

Basically, I'm finishing up a friends car..... its been a LOOOOONG process btw. Car has had numerous "little" issues but overall she getting there.

Anyways, its a stock ls1 with a maggie mp112...

By "rail" do you mean they stick at a certain MV instead of oscillate up and down? Cause that is exactly what I'm getting. The Trims would get "perfect" and suddenly the O2's will stick to 886mv for...

lol wow... :)

OP: The Banish data will help out some however ID's are the way to go.

So, with the LTFT's diabled, do you tune your MAF/VE with the STFT's or with the wideband? (AFR Error %)

The car im working on now (maggie ls1, pulley swap 3.0", shorty headers) has some really...

These injectors sat for a while as well. I thought that perhaps they needed to be cleaned and reflown thinking the e85 had damaged them. I've never seen a set of injectors fight back so much though...

Well.... made some progress today.

I got the car hooked up and started to work on the VE/MAf. Had a few hang up and delays as the car became to act irratic.

Anyways, like I mentioned it...

So far so good.... the ve took about 30% to fall into line. Finishing up the maf low as we speak. Definitely not what I expect for a "simple" injector swap and data entry.

OK... thanks. Ill start there then.

Dsteck: retune the injector data or ve/maf?

Flame: OK, I just didn't expect to be this far off. Seems like the trims were getting leaner and leaner the more the idled.

OK... I'll report back....

Below is the last idle log I have of the car with the "new" injectors. They're Siemens "60lb" injectors part number 107961. They're rated at 60 @ 43.5psi. The car idles around 58psi.

So, at this...

Update: Tried the above changes.

LTFT's are still way high.

Thanks. Are you referring to the min injector pw table? Also, the defaut inj. pulse table?

If so they are long tables ranging from 0 rpms to 8000 rpms. How do you here a single data value? Across...

Update:

LTFT are raising to 15%+

Idles ok but breaks up under lite throttle.
