Got my one coming tommorrow direct from Collins (as i supply them!) the pro version too

Apparently i can alter fueling and ignition plus gives every thing the petel did and just plugs into the diagnostics plug

..Watch for a review soon.
I have now decided NOT to use the S8 but the L8 and this moniter instead....as i am getting a Collins chip which works in conjuction with this moniter i think....and then get it proper set up
Simon...dont send the other ECU i will return this one i got..thanks for your offer but this is a more viable route for me for my diy engine..ie it will go bang soon and i would only blame your ECU..ROFL.
Hope your not offended!
