And top speed? Neat trick. How'* that going to work on a stock PCM?
This will work for NA cars up to 95, as they have no MAP sensor to compensate, but it will buy you VERY little.
I have one I designed myself and spliced into the PCM on the Zilla. I get 2 degrees of timing (about 6hp) out of it when testing. That'* all the PCM will allow. It works on the SSEi because the MAP sensor is only for the boost gauge.
In a nutshell, 35 bucks for a pot and switch is ridiculous. I didn't spend even close to half that on this:
Largely a myth. Moving to General Chat.
