sy ty ecm piggyback on a 730?
What I'm thinking (yea I know that can be kinda scary!), is piggybacking a sy ty ecm onto a 730 ecm. That way the 730 can still controll all smog functions; air divert valves etc. and then have the sy ty for ve tables of 2 bar map.
I know that the dfi has been PB'ed, but I'm not famaliar with the sy ty ecm. Seems like it should be doable....
Any help apprectiated!

The 749 is batch fire. As far as running "dual" ECMs, that won't work. Several reasons, including, the sharing of inputs, and how do you plan on switching back and forth between ECMs without having any glitches. ie , setting codes, misfires, etc? Best bet is to use the 749 solo, or look into using the 730 (repinned to run as a 749) with the syty code. Both have been done. I haven't tried the 749 inna 730 before, but it has been done sucessfully. HTH, Bob
