Camaro 6.2l Tuning Help

You're going to have a tough time,


While still using 28lb injectors and a stock fuel pump.
Both are insufficient for what you have.

Good Point
I have 28.8lb injectors. The fuel pump is Walbro 255lb/hr.
What injectors size I need? The Calculator says 32 lb

[Sid447]

The 36lb,

Bosch injectors would be needed.
Then your time won't be wasted tuning the engine with an insufficient fuel supply system.

The fuel pressure is ok, or it seems ok. I´m getting some hesitation in the range of 1000 to 2000 RPM. I´m not sure if ther is to much fuel or needs mor fuel. It only happen when the engine is not in normal op temp.
I´m also getting the DTC P0101.
Change MAF and still the same DTC P0101

"The fuel pressure is ok, or it seems ok.".. It's one or the other. That's where the data logging of PSI will help.

[DocZ28]

In this moment can be the two scenarios lol. I connect a gauge and reads 59 PSI in low range from 800 to 3000 RPM. I don´t want to test in wot. Cuz More than 4000RPM the O2 goes near .100 mv. And runs like crap.

Just check the FP tutorial, great info.

Finally I have a WB, where to start? Calc VE Tabel, Auto VE, I´m a little confused

Hello Doc,

You can use either the newer CALC VET tuning method, or the previous AutoVE / AutoMAF combination method. With non-OEM injectors, good results will depend on the accuracy of your injector data.

Start with the Calc VET tutorial, make sure you carefully read the tutorial thread's post #1 and it's summary thread.
