dont go driving it silly just get it up to MSD and get the chip re-mapped.

IIRC those EEC-IV chips are pretty expensive so its agood job they can be edited, not the 10p eeproms that go into cossie ECUs.

i once broke a brand new MSD EEC-IV chip by not following the instructions and plugging it in upside down, felt proper guilty when stu did me another for free as i found out the cost of the hardware was almost 100quid
