no EST bypass mode ???
hey guys not sure if this is the right section for this ...mods feel free to move
anyways just installed an HSR on my l98 , the problem i have is when i disconnect the est bypass , the check engine light comes on just like it should however the engine sound does not change, according to tunepro spark relative to tdc is still at 18 degree's +/- , and my timing light would seem to indicate it has that much advance or more ( my light does not have advance). im thinking the issue maybe the module (ignition module in dist) , anyone run into this before ????
