LS ECU is best mounted where ?

[MARKDTN]

For any kind of driver I would leave it underhood. All LS (and LT1 and Vortec) PCMs are weatherproof and were mounted under the hood from the factory. No so with all TBI and TPI although for Speed-Density TPI they were underhood on Corvettes and the same PCM was used on 3.1 Cutlass, Lumina, Grand Prix..... I do like fuses inside if possible. But behind the glove box-especially with A/C-is taking up valuable space.
