I'm having the same issue with my car. If I try to give it throttle after coastdown and rolling through a stop sign at 9 mph, the car also jerks pretty hard downshifting to 2nd.
Post a log and...
Great info. I do have an 08 ecu and it is CanBus. It would work. I was just thinking for 80$ less I could just use the 0300 and call it a day. I don't need racing stripes on a Cadillac kind of thing.
I was told the DC 0-5 offset needs to be calibrated each time the wideband is connected. "If you want correct AFR, the 0-5 dc will have a offset that will need to be accounted in the algorithm you...
They are stock ls3 injectors I believe 38 lbs? I have not installed a wideband, I was going to go with an AEM 30-0300 but everyone on the G8 page said to go with the OBDII 0333 one as you dont have...
What should it be? Are you saying it may just be that the injectors aren't spraying enough fuel even though I am commanding plenty?
Just ran a full tank of 92 Octane gas. Knock came back. If I splash in some more fuel, around 12.2 AFR and retard the timing 2 degrees in each cell, it goes away. Would this be an indication of bad...
I was trying to use the ethanol as race gas to determine whether or not the knock was false or true knock. I do not have the sensor for it yet. I ran 12.56 AFR, 14.68/1.171 , and I had absolutely no...
So I loaded up with 3.5 gallons of E98, essentially race gas, and 15.5 gallons of 93 octane gas. Giving me abut 100 octane fuel. Went and made 3 pulls. Still getting knock. I will post the tune and...
@06MonteSS,
If you take a look at the AFR on the dyno log it is below 12.0 AFR even when there is 8 degrees of knock. Should the commanded afr still be 12.2 instead of 12.8?
I remember removing the knock sensor to make it easier to install my starter. I may have it misaligned or over tightened. So I ordered 2 AC Delcos.
When I get back from vacation im trying race...
Hi all,
Brand new to tuning but have been on the Gen 3 and Gen 4 LS platform. Currently own a 2008 Pontiac G8 GT L76 with 77k miles on the odometer.
Had it taken to a shop in Toms River, NJ....
