Hmm so you are saying that per bank (or per cylinder) fueling controls exist, but they just aren't exposed via hp tuners? But the ECU does in fact control fueling for each bank separately?

makes sense!

I don't understand why GM has O2 sensors to get STFT data for both banks when the ECM has no ability to control fueling or spark for each bank independently, wouldn't it have been more cost efficient...

That worked perfect thanks! Also got my STFTs looking slightly more reasonable, although they are still rich.

I got another problem now though. When I am idling and I rev it up to around 1800 and...

So I got my car (2009 z06 with ls2, ls3 heads, cam) idling but it only starts up when it is cold, when it is hot (ECT ~130F) it cranks and then starts to fire but then immediately dies. I know there...

So I got the fuel trims to work by disabling P0068, looks like I am running really rich, I'm going to flash the car with the adjusted virtual VE tables tomorrow and give it another shot but does this...

Could the P0068 be causing the OL - Fault Fuel System Status? I noticed some settings here to control this code:

123056

Should I bump the rpm enable to disable it while I am tuning?

Hi Guys,

I started up my car for the first time this morning looking to tune the car in speed density mode (forcing MAF disable via the tune) at idle using the STFT but I am not getting any short...

I got it working! I took the plastic tabs out of the adapter plug using small pliers and made sure that all the pins were properly connecting to the wiring harness and now I am reading a steady 96kpa...

So I figured out the problem, the adapter I am using doesn't fit properly. I tried to jam it in and the pins were never connected so it was reading garbage.

Does anybody know what adapter I should...

My car is a 2009 z06 that has had the stock ls7 replaced with a heavily modified ls2. The map sensor is a bran new OEM ls3 map sensor and I am using the required ls7/ls1 to ls3 map adapter cable to...

I didn't flash that exact tune, I copied the differences to my stock ls7 tune using the comparison log window. But yeah I do see that it is an E40 tune which is odd because Dave_In_VA mentioned that...

I noticed in the vcm scanner app the MAP sensor was reading 7 kpa in accessory mode which seems completely wrong. Seems like the sensor is bad, I?ve ordered another hopefully it will read around 102...

Just loaded this tune but unfortunately the car doesn't idle, just fires up for a second and then dies. Interesting enough if I load a stock c6 corvette grandsport tune it does idle but only if I...

Awesome thanks a ton! This helps a lot. And yes I am using ls7 maf not ls2. I?ll load this tune in and see how it goes today.

Definitely helps! Thanks! I?m going to try to start it tomorrow. Fingers crossed everything goes according to plan!

Bump, can somebody help me out here? Don't want to damage my engine!

It is a c6 z06 e38 ecu the ls2 has a dry sump ls3 crank cam and ls3 heads. I actually don?t know the exact specs of the cam I just know that according to the guy who sold the longblock to me it is a...

Hi There,

I am finishing up my ls2 build soon (ls2 with big cam and ls3 heads) and I am going to be starting tuning. I will have access to a dyno and a wideband AFR meter. This is my first ever...
