Discovery 2 LS Swap Conversion Board - Gen 3 Engines and 4HP Transmission

This board has been tested with LS swapped Discovery 2 vehicles using a Gen 3 LS (e.g. LM7, LM4, L33...) and retaining the stock 4-speed ZF transmission. NOT for Gen 4 and 6L80 transmissions. It takes the tachometer signal from the GM computer as input, and outputs a Rover 58x CKP signal. For vehicles swapped using the ACE kit, this board replaces the flaky rover crankshaft position sensor and reluctor wheel located behind the harmonic balancer. This board also converts the Rover VSS signal to the GM VSS signal, fully replacing the ACE kit's black box.
