I would keep the LS2 MAP for simplicity and easy of compatibility.

I am installing LS3 heads & intake on my LS2 05 Corvette. Should I keep my LS2 MAP and make it fit the bigger hole or what?

When are you going to start building these? What do you think the turnaround will be and what are you planning to charge? Also, do you reprogram the computers or who do you recommend in the area for that.
Thanks!

Yeah I found that in the GenIV PCM’s you can modify the linear MAP settings, but it’s so much nicer running the correct sensor that the PCM is programmed for lol. Javier’s vette was a headscratcher, but it ended up being a simple fix.

The LS3 sensor has a negative offset and a different linear range. The offset is fixed (except custom BOOSTED OS’s) but in all GenIII cases seems unable to be entered as a negative value.

Hi Con, recalibrating the VE and MAF tables should only compensate for the change in fuel flow with the Ford injectors compared to the OEM injectors. You shouldn’t see a reduction in power at all since you’re just increasing the capacity of your injectors. Have you logged your air/fuel ratio with a wideband since the injector swap? I’m assuming you have, but just checking. Are you using a dyno to figure horsepower or are you using the trans input torque PID from the computer? Using a dyno is the only real way to see what power you’re putting out. The input torque PID uses a number of airflow tables to calculate torque input based upon total airflow and commanded fueling. Somewhere on the HPTuners forums there is a detailed description on the calculation, but in a nutshell it’s not very accurate if you’re anything beyond stock-like airflow. For instance my “calculated” trans input torque from my PCM reads out around 350 but I’m actually putting about 350 trq to the ground. Anyways, if you want to email me a log of the car I could look at it to see if there’s something obvious.

Thanks!

Fantastic write re calibration of 42lb injectors for GM application.
I was wondering by changing the offset voltage as per your recommendations and re-tuning the VE table, would it cause a loss of power, or should I expect to see the same rwkw.

I was down 35 rwkw, after changing the offset and VE table.
I suspect that I have other issues and not the injectors.

Thanks

Some tall guy named Matt picked it up for me! Thanks again for the favor man
