After reviewing many log files in excel just now my fuel pressure is dropping way to low even with BAP so im ordering a external secondary fuel system. Even tho my AFR's are fine to redline at 11.2...

Just curious if using 60# injectors (with correct data from Gregs dvd) with current IDC's of 100% at 5800 if changing to 80#ers (and changing to correct data for those as well) if fuel pressure will...

Thanks for the link...
I can of course just run in OL as well and not worry about the NB's at all but hot/warm restarts are always a bitch because afr's drift way lean and hard to control so far in...

I wanted to see difference between OL and CL MAF afr error% with VE table completely disabled. OLFA table is also all 1's at operating temps for this test as well.

After a long drive not going...

Yea ive double checked over and over for weeks but the car just runs better in OL vs CL in light throttle conditions. Doesnt really bother me being in CL but its noticeable off slightly going from...

Yes I noticed how much better my car runs with MAF open loop with no stft's being used to correct when stoich value was changed in the table for E10. Im tempted to run MAF OL all the time and not use...

No not tuned, all the other cars are just reg daily drivers for wife and kids and such.

We have 6 vehicles and every single one of them gets 3-4 worse mpg with the E10. All the cars run noticeable worse as well especially on a warm day. Its corn fuel BS is what it is.

I just bought a ethanol test kit as well today and will be checking exactly where ethanol % is and changing stoich table accordingly.

My gauge only reads afr, so im kinda stuck with that for now....

Just curious how many of you guys tuning out there actually change the stoich value table input for using ethanol enhanced fuels such as E10 or do you just leave it at 14.7 and then just adjust the...

So if the stock 02's are off say +-4% and you use WB instead to tune then once you actually go and view the stft/ltft's histograms then they will always show it being off like +-4% since the wideband...

so if the wideband reads 14.7+- when stoich is set at 14.7 and then changed to 14.13 i would mentally have to just subtract .5 to whatever gauge reads for anything other than idle/cruise since it...

Lots of used copies out there now for sale. Lowest ive seen is $125 (quite a few). Most going for $145-175.
I mean once you watch it and get the info needed it becomes a dust collector so no need to...

Go for it as ill be waiting patiently for the info....:bigshock:
The info will eventually all make its way to the net anyway and the repository here will have someones tune posted with all the...

I just happened to check some of my logs from a year ago with my old blown motor that was tuned by a tunershop and noticed I had no DFCO happening then either as IPW never fell below 1.6ms ever on...

So you tapped into the purple wire coming right off the sender going to the gauge?

Here is the diagram. You are suppose to come off the gray 5 volt reference power slot not the purple wire or it...

I called Autometer and some tech there told me they no longer sell or have or then he wasnt sure the correct pigtail to plug into the back of the gauge that can then go to the HPtuners interface...

Thanks! I figured I was confused but doing it the right way. There is a MAF error histo in the hptuners histogram folder to use so I wasnt sure why anyone needs to use this other one if they do the...

So why does this config have LTFT in the file name? isnt dialing in the MAF using WB afr error %?

I'm confused cause the config file has LTFT in it and the filtered histogram file has STFT...

Im just setting mine to enable at TPS 7% AT 4400 and under. Im just more interested in the lower rpms enabling.

So it looks like its just personal trial and error what to set it at for what rpm cells. I guess best place to start is just get it enabled at lower rpms and see how it goes. I dont think I wanna be...

My table is stock setting which says TPS must fall below a certain % to enable DFCO. Right now I looked at my logs and my TPS % never falls below 5% at idle or deceleration.
I guess this iswhy I...

update this morning...I took some more time dialing in my MAF better, redid the OLFA table and put lower values in the PE enable tps threshold vs rpm table. STFT's are all within 1-2 now.Man what a...

My wideband is hard wired into power all by itself and the ground is all by itself as well. I checked WB to make sure it was reading right and adjusted my pid voltage offset in CL to correct it when...

So I finished tuning in OL and got the AFR error % to what I thought was close after 5-6 back and forth logging and changes and applied to VE table but when put back in CL my STFT's are off about...
