What kind of software do I need for GM LS2 ECM?
If, for example, you are working with an LS2 engine pulled from a 2005 Pontiac GTO and source an ECM from a 2005 Corvette, the ECM must first be reprogrammed with GM’s TIS2Web software using a 2005 GTO VIN. This replaces all calibration segments and turns the ECM into a 2005 GTO ECM.
Where is the ECU located on a LS engine?
ECUs in 1997-2004 LS engines utilize a 24x reluctor wheel on the crankshaft and have the cam position sensor in the block, at the rear of the intake. Gen IV engines have a front-mounted cam position sensor and use a 58x wheel on the crankshaft (aside from 2005s utilizing the E40 ECM).
Can a corvette ECM be overwritten with custom tuner?
As an example, someone using an LS1 Corvette engine need not source the PCM directly from a Corvette. A tuner can simply begin with a calibration file pulled from a Corvette PCM, make necessary changes, and then perform a full flash into any PCM with a matching service number. Gen IV ECMs cannot be fully overwritten with custom tuning software.
Can a LT engine be swapped for a LS engine?
The number of vehicles that are now receiving either LS or LT engines is amazing. You don’t have to look far to see LS-based engines winding up in Mustangs and Miatas, so there’s definitely some benefit to jumping the fence and swapping in one of these late-model powerhouses.
If, for example, you are working with an LS2 engine pulled from a 2005 Pontiac GTO and source an ECM from a 2005 Corvette, the ECM must first be reprogrammed with GM’s TIS2Web software using a 2005 GTO VIN. This replaces all calibration segments and turns the ECM into a 2005 GTO ECM.
Is there an aftermarket engine management system for a LS engine?
Of course, if you are buying a crate engine or can’t get all the original components, the aftermarket will come to your rescue. They offer engine management systems for both EFI and carbureted engines (carbureted LS engines are available from Chevrolet Performance as crate or carb-converted Gen III/IV engines).
