Also in your original tune you are using a flow rate multiplier of 1.800. This effectively just makes your entire IFR table 63.5 for all cells, if you are not using a vac/boost reference regulator...

To update on your cyl airmass issue, in your log the dynamic airflow matches the VE airflow. The standard hptuners parameter for Cylinder Airmass uses MAF airflow for the calculation. You need to...

The LSJ p12 pcm will not read over 2.5 bar no matter what, only way to do that is to purposely scale the slope of the MAP calibration which will basically mean the pcm will be reporting xx% less MAP...

Maybe im looking at the log wrong but your o2 sensor is seeing varying voltage and your stft are still enabled under that boost. What afr was your wideband reading? Also your injector pulseewidth...

Okay even with EVAP plugged it still won't idle smoothly, if I unplug the maf it will idle perfectly after setting the MIL.

Idle timing stays basically at -5deg all the time with maf enabled and...

So on my way to class this morning, car idled fine and even did ok with the AC on.

I am almost thinking something gets hot and doesn't seal as well, going to look into it soon, but when the engine...

Well on a supercharged setup the EVAP doesn't take boost, but i may try plugging it to give it a shot.

Yeah i thought that, but even open loop maf with evap isnt smooth.

Did you plug off the TB?

I am thinking it has to be some sort of turbulence or unmetered air throwing it off.

It idles...

Alright so I have been dealing with this problem ever since I have had this car, I have tried 3 TB, 2 MAFs, 2 MAPs, and all that and the car literally refuses to idle smoothly, its reasonable with...

Looking at the tune you had there, those were stock injector numbers. You really also don't wanna be copying tunes off the repository directly.

I recommend reading up on how to tune the car alot...

Alright let me post some stuff I got

Pull here in 4th and 5th, both starting below crossover point

The airflow analysis

As I can see, my VE table is actually still a bit lean...

Right now on my TVS car I am not having the lean problem at all, I am using RSFS and 80s with a flat IFR table and dynamic switch over at 3600rpm. Be and maf both reasonably dialed in, and both...

This is definitely some really good info about how the VE table is really used, I always understood it as the pumping efficiency but I always just kinda thought of it as an alternative to MAF...

cobaltssoverbooster,

thanks for the good information, now i see why when I continued to retune both tables on the TVS setups, they fixed the issues. So essentially VE should be tuned first once...

Ve is also important in starting the engine

68251

As you can see the MAF doesnt measure the the air already in the manifold at atmospheric pressure that is first pulled into the engine on start...

It uses VE when theres quick throttle changes, I did see the dynamic lean issues on my friends cobalt when tuning the TVS as well but it went away as I spent more time on it. MAF should still be the...

Already had MAF dialed in on a friends LSJT, s256et.
Set timing low (10deg) pre spool WOT to raise egts, then ramped spark with rpms to 20 deg at redline (E85)
Car pulls great in MAF only at WOT,...

Are you talking about offsets or short pulse adders, if you zero out the offsets then im suprised the car actually ran well at all.

Offsets (Which are not part of the INJ PW as reported by an LSJ...

Get more E in there haha, I did E47 for awhile, just 5 gal of each when I was below 1/4 tank and I was able to get 25deg of timing out of my TVS so you should be able to go far with a turbo on that I...

My m62 on K&N only hit 9900Hz, my TVS 2.9 hits 10800Hz, we will see what happens on ZZPs tube, Hoping to get 25deg of timing on full E85 as well, I am sure it will have no problem.

The 60-100mph...

Really hit it that soon, what size MAF tube? I was hoping we would hit 20psi around 11,100Hz

Without BRFS i am thinking thats where I run out of injector, the TVS on 2.9 was pretty much there on...

Friends getting a ZZP s256et trubo kit put in and we will be tuning on 80lbs injectors on full E85.

What kind of boost would we expect to get before 100% IDC, also when do people usually see the...

Are you saying your coolant is hot?

No lean will not burn hotter, stoichiometric mixture burns the hottest generally and your o2 sensor is gonna try to get lambda.

Do you by chance have the...

I see I did look at the tune but didn't look at every table, that's a bummer. You could at the least use the fuel trims as a way of dialing in the fueling on the VE tables.

Then use your wideband...

I would cut back on timing till you get that fueling stabalized, you had quite a bit of spark knock, with boost that can cause damage quickly.

Do you have an error histogram for VE using your...
