dohc chip

[phantomgreen]

If i were to buy a chip off of the store, would it be tuned differently for 6/6 timing rather than stock timing for a 93 dohc auto. Deciding whether to buy it before or after i time it. thanks

I haven't done any tuning for the different cam timing.

when i do my Timing belt next year, i'll be doing the 6/6 mod when i do i'll check the changes after im done tuning. if you want i'll let you know if there was any noticable fuel or spark changes in the tune

Cool, id like to know what it changes for obd2 but a maf based setup vs a map based setup means I couldn't take any of your changes and convert them.

well i could always do a VE tune... which is a speed density tune after... its a good idea anyway... once you compare the two you should have some idea how they are effected
