You need to be very careful when cross comparing. You don't know that people have set ignition Maps from the same base, fuel maps from the same pressure etc. I tried to use 4 professionally tuned Maps from identical engines when tuning my 3SGTE but there was so much variation across them that it was impractical, and the final tune I got to was different again.

My st170 is going on the rollers on Monday, but is on an ME221 ecu. Happy to send you my stuff once done.
I am using a VVT map at the moment, but MS can only switch on/off I think? And that won't give the best performance by a long shot.

hi i have the ms3x which does variable vvt yes would be great if i could see your maps thanks

OK, I thought it was just on/off with MS.

Anyway, drop me a u2u early next week to remind me, along with an email to send the files.

Cheers
