evening guys.

does a standard p8 ecu have a pectal board or is that a mod?? (escos 1992)

i ask this due to mine is running a pectal board with map for greys etc. i've just rebuilt the engine and have a p8 stage one chip that i was going to run the engine in with.

problem is when i fit the stg 1 chip to the pectal board, i loose inj pulse and spark.

then put the other chip in 'for greys' and all pulses are back.

do i need to take the pectal board out and run the stg 1 chip direct


cheers
Dave
