Incorrect MPG (too high) displayed on DIC after SD re-tune

Log this real quick. Deka 60 info. Stay light on the pedal. Keep it under 3000.

Perfect example from just a few days ago.

You can't imagine the junk I've seen over the years.

Wow...I haven't seen the actual tune file, but from the conversation and post i can tell it iss pretty sketchy.

Any particular channels you would like me to to have logging?

[SiriusC1024]

Just for now as a check the standard channels. If not present add STFT's per bank, cylinder airmass, wideband, throttle position, injector pulsewidth per bank, and dynamic airflow.

It ran rough. High idle, random stumbles.

You have a data log of the previous file?

Sirius did nothing wrong. What it's looking like is the injectors are bigger than 60#.

No problem...here is one from the previous tune before going speed density. It has a mix of driving conditionssunday pull.hpl

I can log one later on the current SD tune that i have been driving with.

Yes please.

Wonder if you were to put the fuel capacity from its current 18 gallons to say 15 gallons. That may inadvertently correct some data.

The thought has crossed my mind. Wouldn't that affect the gas gauge performance?

That's not going to correct the IFR/VE dilemma. I don't care about the registered MPGs you can "back in" to that. The injectors look like they're 100#ers.

Here you gotest 2.hpl

They look like deka 60 based on the part number

Log this, please. Actually, it looks like it's going to come in pretty well. Also, what cam?

this cam right here:

Log will be coming later on.

[edcmat-l1]

Looks like the VE numbers are going to come in too low.

[SiriusC1024]

Even with that cam you think?

[edcmat-l1]

Looking at the 100 Kpa row, yes.

That being said, get it closer and let's see what it looks like.
