New Fuel Pump VE Try 2

[TheMechanic]

I use the Pro Feature set because I don't leave mine in a vehicle. I hook it up, tune, and take it off. If it is going to be permanent/semi-permanent then the EGR method would be better. You could use some weatherpack connectors so you can quick disconnect the WB when not in use.

I want to use the existing glow shift fuel pressure gauge to feed into the scanner too I know my ac pressure circuit is already cut into for my e fans I mean a serial cable tucked somewhere shouldn’t be too bad

[gtstorey]

Have you confirmed that your glow shift is a 0-5 volts (or about that)? My Glow Shift fuel pressure isn’t, but they do make one that is.

Have not tested the glowshift tried connecting the new wideband via serial but mangled one end so im back to egr just trying to get offset correct its the aem 30-0334
My math is ([2811.10]*2.3750)+9.3125 still have to adjust a little

It's not far off.

No the 12.18 is like 11.88 but seems good to keep moving forward

How do you like that AEM? Mine just took a shit a couple days ago. Has the SEnS error after not even 2 years. Apparently it's a common problem that they don't want to address. Conveniently it only has a 12 month warranty. If they don't want to replace it I'm getting an AutoMeter and will forever recommend against AEM. Have to redo the install either way. They're nice while they work...

Looking forward to your next log.

I like the aem but honestly the wideband had the light for night driving pretty sure the 02 just shit the bed but seemed like aem was more compatible with hp tuners and amazon was willing to give me a full refund for a purchase on the auto meter from 9 months ago so I said why not lol. The tech support from auto meter kept saying it was a wiring issue if it stayed stuck at 14.9 14.8 etc but I looked up the cost of the actual o2 replacement from them and it was 124$

Warmup and some pulls fuel PSI No Longer drops after 4k rpm
1 1 warmup.hpl
new wideband SD 1.hpl

[SiriusC1024]

Ok log it a little longer. 15-20 minutes. Make sure it's up to temp for the log. Take WOT runs to redline. Clear LTFT's.

injector data 6 Run 1.hpl

The VE table shape and magnitude of values looks off, but that's what both the fuel trims and wideband indicate. The injectors make it a little difficult to tune, but it's pretty much there for the VE table. Let's move to MAF tuning. Since there have been so many threads will you post the original tune? Need to see the values for MAF settings.

[Lxjoshxl]

So Turn SD Off? heres the original one after the swap before intake etc
1 Current tune 8049 my 01 silverdao stock tune MOT verified file MOT4 added p0700 and added -35 .hpt

[SiriusC1024]

Ok here it's set to MAF.

I edited the file in the post above due to uploading the wrong one. Saw a 7 at the end of the file name, but it wasn't for yours. Now it's there.

Get a log of this. Start slow. Quick 5 minute log up to 3000-3500 for this one. Don't go too high because no telling how off the MAF calibration is.

[Lxjoshxl]

tried to run it different ways wont run at all tried commanding closed loop
maf re enabled commanded closed loop.hpl
maf re enabled commanded closed loop 2.hpl

[SiriusC1024]

It's was pretty far off.

[Lxjoshxl]

maf 2 run 2.hpl
maf 2 run 1.hpl

[SiriusC1024]

Feel any difference between MAF and SD?

[Lxjoshxl]

Seems like pe in SD was better normal driving around seems a little quicker I know pe is irrelevant either case

[SiriusC1024]

Ok. MAF PE should be better next run.
