ConsultingTuning
We recently helped a shop with a handful of remote calibrations on a cammed LS3, a built LSA ZL1, and a 416ci supercharged GenV LT1. All three needed to have good street manners. Our client is an experienced builder who just wasn’t as familiar with modern ECU calibration, so he enlisted our support to help finish up these projects so he could deliver to his customers. Honestly, the cars were built great, and really did only need that final calibration support to make them shine. Just our kind of project.
We worked with the shop owner to make sure he was grabbing the right data in the logs and instructed him on the proper way to collect that data so we could make intelligent and effective calibration changes each time. We started by inputting known injector data, undoing a few unwanted things from previous tuners, and setting the calibrations up more like how GM would have done it with a solid physics-based approach. It took multiple iterations on each vehicle to walk our way into the right values across dozens of tables. Going back and forth required several days on each car, but the results were nothing short of fantastic. Fuel trims returned to stock-like movement. Knock detection remains active, but not intruding as long as we have good fuel. Finally, we restored the drive by wire torque security checks on all three cars with proper safety calibrations that match the new hardware without turning off the monitors. All three cars made excellent power with drivability that far exceeds the previous “big name” tunes and customer expectations. To quote our client:
“I took this out for another drive, I think it drives great! Cruising at 35 mph in 4th gear, smooth!”
“Thank you for all the work you put in as well Greg! Without your help I’d be in deeper trouble!”
