Shooting for a wed TNT- how does this look?

[detroit]

Here is my work in progress. I have added 2 degrees of timing to the areas I logged.

I am done with my VE. and my PE matches what is commanded at WOT.

@1000 frames in the log is a WOT blast.

issues:
Still has some suringing at slow speeds, and sometimes stalls. It does this more with stabs of the throttle.

AC on causes some issues.

Starts with a high idle, but I think I'll be able to fix that with a RussK log when my temps get a little colder.


I want to goto a TnT on Wednesday but need to have a good idea of what to work on

got the tune/log off this computer will post again later

Hey Joe How's the tune doing almost dialed in?

[detroit]

its coming oscar...sometimes it feels strong, sometimes it does'nt

com'on forum....live!

[detroit]

so its wednesday...wish me luck, b/c your suggestions suck JOKE

[detroit]

Bump for help...and a upcoming Tnt (again)

ANYone wanna look at this tune and let me know how it looks?

[mecanicman]

Your VE could use a little more work. Looks pretty good from the log.

I assume u are NA if so y are so running it so rich at WOT.

[mecanicman]

Running e10, stoich set to 14.1, 14.1 x .85 L =12.0 was my guess

[detroit]

thank you so much for taking the time to look at my tune. It is a big help. thank you.


I will give it another round of VE tuning. I have been playing with AC torque adding so I should hit the VE again.

I think its close but know it can always get better.

I am going back one tune to the one with less timing, my IAT temp vs timing was pulling atleast a degree during normal operating conditions and I have changed it to look like a zo6 one where no timing gets pulled till IAT's are 133 or higher.

Bump for a new day, new sets of eyes...thx

How about some more information on your mods. What injectors? Your injector data looks off.

[detroit]

they are marine 42's. I am return converted to returnless with a vette FPR. I need to stop bs'ing and get some 60's so I can run e85....but I digress...

would anyone guess my ET? could this run a 12.9?

[detroit]

bump...anyone wanna throw their 2cents in....

Post up your most recent tune if it's not that 1st tune you uploaded and I'll take a crack at it.

[detroit]

still working from above posted tune...

[Rinkrat456]

You could lower your PE enable TPS value from 90 down to a non-linear value like that of the LS6. What if you were at 80% throttle or 70% throttle revving to 4000-5500? You'd still be at stoich instead of a safer A:F, plus it will feel stronger down low instead of this burst of surprise as soon as you hit WOT. You can change your enrichment rate to 4 also to make these changes happen sooner.

As mechanicman pointed out, your VE table could use a bit more lovin'. When you've got that dialed in a little better, look for the most recent Cranking VE thread I started to get an idea of what to do with your Cranking VE table.

I have the PE enable that high so I can tune my VE. I am going to lower it to maybe 70%. I'll look at the ls6 table.

I am going to do a cold start to get some better data for my idle air, then I will hit the VE more.

I found one table that was pulling timing at operating temps so I changed that to look like a ls6 one. It wont pull timing till IAT's of 133 and higher.
