I need help also getting the 3bar tune in my 09 cobalt ss
Cam,E-force supercharged L9H topping out at 12lbs boost, headers,ID 850's, pre- boost meth,ported 90mmTB
Is a 7% split worth doing anything about? Will it hurt anything just to leave it be ?
What would cause a 7% split in fuel trims ?
Yes i have been playing with the FA multi stage 1 vs time table, it differently does something, it seems to do a lot with little changes in that table. The description on that table mentions a stage...
Thankx schpenxel. Why in the log do the commanded numbers go below 9 and closer to 8.5 for that short stretch and the open loop gains table shows, around that intake valve temp and kpa, assuming the...
Oh darn, i'm sorry here is the log. My truck starts and runs but when it goes into commanding the 8.5 AFR it starts to stumble and check engine light starts flashing,then all is well when commanded...
Would the Open loop gains table cause the Commanded AFR to dive into the 8.5 range seconds into a cold start. Check out the attached log
I was wondering if anyone could tell me what tables control the commanded AFR i see during logging at the beginning and the first 20 or 30 seconds into a cold start, before going into closed loop on...

Is there a way to use an actual flex fuel sensor on a virtual flex fuel truck ? The reason being, i want to run E85 and i want accurate,reliable readings on Ethanol percentage
Yes 0=Full Advance, negative numbers won't do anything, the phaser is spring loaded up against a positive stop when parked at home with a zero in the table. Oil pressure pushes against the spring...
I get knock when logging idle when i shut my door kind of hard, i guess the knock sensor is picking up me closing the door and i'm not slamming it shut. Just make sure it's not false knock
Zero means zero retard is set on the cam, it is at the parked position at zero. You get no cam advance with the VVT system it will only 'roll' retard in as RPM's climb, a 2 or 4 in the table is 2 or...
Question, where are these VE Tables. And if i have 100Kpa at key on, isn't anything over 100Kpa when engine is spinning boost ?
ok thanks i'll let it sink in a bit
Ok thanks GHuggins i will try what you are saying. i will take a little bit to get what you are saying and have it sink in, meaning i'll have to reread it a couple times to be sure i understand what...
i live in Maryland. My truck runs great just a few quirks at cold start up. Do i need a whole new tune for this ? Would bad injector data make the truck run real good other than cold start. It runs...
Would the fact that i'm running meth be why the PE setting is set to 13.52?
OK, thanks for the input daveonline, every little bit helps. I don't have a wideband installed yet,but i do look at the commanded AFR while logging. I do understand that this doesn't mean much...
My injectors and data where installed by a well known tuner who does hundreds of these,not sure how he would have put the wrong data in. This morning i hooked up the scanner,read the ECT, then i went...
Can you tell from the log, is it trying to add fuel because of an airflow reading or is the timing causing it to try and add fuel? What is triggering what there?
No not stock injectors,ID 850. Have an E-force supercharger running 10lbs boost,90mmTB, cam upgrade and a meth system,and headers. I have had it tuned on a dyno after each up grade.Started having...
Thanks for the response Higgs, i just wish i knew more about what you are saying. Did you look at my tune and see something wrong?
