That vette is prolly pretty quick. Im about to stuff a cam in the tbss, similar specs to yours, bit smaller tho
That idle tuning guide looks legit, i look forward to tryin that out once I get...
No worries. I mean your stomp factor. Use the navigator (ctrl-N) enter 13624, it will access that table
Not necessary for now,imo. Your car has a PWM fan, right? Im at the airport not in front of my laptop
add 10-15% to ECM 13624, it might help any lean spots/hesitation during gear shift. helps my TBSS
- do this after MAF and VE are adjusted to your liking. If it goes too rich according to your...
I'd do the VE next, driving in the same conditions etc. Then re-enable both and work on the idle, prolly. Don't worry about WOT for now, get it driving normal and reliable on the street, idling...
add 5 deg of timing in your idle rpm and g/s areas in ECM 12612.
your car sure does like to run warm, geez. maybe shes ridiculously lean. check the plugs, two cents. this will confirm lean...
Maybe take a look at the plugs. That will tell you if you’re lean, at least. Lotta money on this engine.!!
IAT 2 is the post-compressed air, in the intake manifold, right? I could see some fueling be off if that somehow is reading 32F all the time. I'm not up to speed on C6s tho. I'd take a look at the...
yah maybe. your VE tables look OEM, which means you either posted the wrong file for stock comparison or you haven't made changes to the VE table. just for comparison the stock min air lb/h for an...
and then comparing the LS3 to the LS7 stock. LS7 with the oem 210/230 cam. seems EOIT is advanced, if the boundary-ECT-RPM is true, which it is, so interesting. Seems to have a pattern, advancing...
interesting comparison of boundary degrees when at 180 ECT-
comparing the LS3 to the LS2(truck). 3 has 42 pph, 2 has 34 pph.
Cam is almost the same, with the only exception being .025 more lift on...
Not to sound weird but your log looks pretty good to me.! I’d be happy with that if it were me. Just my lone opinion tho, obviously. You probably already know, but drivin around in MAF only can...
TBSSs rule btw. love my black 07! good advice from TCSS07. im gonna go disable that damn cat and post O2 test on mine
i think your VE table is too fat and the computer is losing its mind as it moves from steady state (MAF) to transient (VE table) when you move the pedal. looks like the entire ve table multiplied by...
cause putting it MAF only mode and adjusting the MAF hz or PE EQ according to the wideband they install is fastest and easiest to show gains on a dyno. two cents
does absolutely nothing for daily...
you could also look at the plugs to verify
no worries man! no need to send the tune file, yet, imo. Re-enable LTFT (thought you had that on, which is what made me say you have it tuned perfecto) and watch what it does. If you have a vac...
Could also be a weird crack in the plastic, etc. try to get a log when it happens out of the blue
What mods have you done to this hog
computer pulls timing when rpm is high to drop rpm. Vac leaks usually raise rpm and indicate lean on trims, duh. Check that puppy for vac leaks. Check the entire vac system, pcv/evap, everything....
My old tbi 350 in my 91 silvy would idle like it had a cam when i disconnected the SA adv wire from the ign module when setting base timing on that engine. Distributor, man! Haha.
That lopey idle thing can easily be caused by reducing timing, something that your log shows is happening on starting. Timing overcorrection will definitely cause an over/undershoot of target rpm,...
Yah, for sure. Been reading a ton on this EOIT thing, lookin at c6 ls3 cars comparing stuff, seeing how gm does it (re inj timing on the same platform with the same engine across different years). ...
Yah mine has 5 initial degrees in then when it catches and fires up it hits 17-18. ECT is 178, IAT 128
unless your closed loop temp is like 130, then it would be in closed loop, log says its in...
