How come no wideband in the log? Don't have one installed?
How come no wideband in the log? Don't have one installed?
I do not have a wideband installed to log into hp tuners...just a wideband gauge
here's the log. Ran better than your last one but still kinda rough test 3.hpl
2004 z06 BTR stg. 1 blower cam with ECS 1500 kit and 3.6" pulley, forged rods and pistons...it does ok!
Looks like it was hitting the lower limit of the injector min pulse. I've adjusted for that. VE adjusted also. If it's too low then it'll come back up on the next.
You really need to have the wideband logging for higher loads later on. What wideband/gauge are you using?
Thanks for the help...I mean it. I currently do not have a wideband logging and I'll have to take a look if the one i have can be set for logging with my MPVI1. The gauge i have is the one on the link below. I will wait till i have a way to log WB before i send another log. I don't want it to turn into a guessing game, nor waste someone's time.

There's plenty to be done without the wideband. Another log would be useful.
If you click on the Installation Instructions in the link it'll show you the pinout. Analog out Brown and Black can be wired to the EGR position. The logged EGR voltage can then be converted to an AFR value.

No, the pins in the PCM that would have been used for EGR Position on the vehicles that were built with EGR (if yours wasn't). You can then log the PID for EGR Position and get a raw voltage, then set up some math that will convert that voltage into EQ Ratio numbers.
Lambda:
([2811.10]/(5/0.673))+0.683
AFR:
([2811.10]/(5/10))+10
Y'all know that car never came with an EGR right? I'm sure it can be wired up but it's not there to begin with.

Has the trick of flipping the EGR master switch to 'Enabled' stopped working or something? Why spend the money for pro features (sorry, HP Tuners) just to get an analog input when there's one being unused sitting right there doing nothing?
My comment was strictly about the wiring not being there.

Here is the log you asked for. Car felt better from the last tune, but some small things like start idle and idle down felt off. Great job though on remote tuning! test 4.hpl
Will def need wb logging for higher level of presicion.

Alright. What about it felt off? Was it stumbling or just not as choppy? If it's chop that's because I messed with corrections last tune.
While coasting down in neutral had some iddle hunting symptoms. It sometimes idled high (1200) and sometimes low (600). Besides that, not bad. Chop was there.
Afr was pretty good...idled at 14.4 to 14.9 and cruised at the same afr. I really wish i could provide you with wb data.
I see. Run this instead. Add dynamic airflow to the logs.
Here you go. It idle a lot better and it runs really smooth. The idle speed dips a bit when coasting but not too much.test 6.hpl
I am pretty impressed. I can only immagine what you can do if i were providing you with some WB data.

Thanks
Not going to get too carried away with idle until VE is good.
I'd like to try something. There's another set of Deka 60 data that's been updated. By updated that means a different person doing flowbench data. Both sets are from FIC. Currently, there's inconsistency at low injector PW. Look at what STFT is doing at the cursor vs the tabulated STFT value.

Also, adjusted O2 for airflow modes to increase drive.

Right. It's the distribution to make the average that's the problem. STFT at the cursor should be close to the average if it was consistent at that MAP/RPM point.
