Matt,
We're looking into what's involved in tuning the various sr20 ecus that are out there. Are all the sr20 ecus a simple rom chip replacement or are they more complicated like the ka24de that requires the biki type daughter board? What are the current options as far as using the romulator/nvram with nistune? Consult supported from the factory?
Nistune for the SR20s. What's involved?

currently as it stands we have 2 built up SR20 boards with a third being built tonight and a fourth PCB to be built next week
these are a multi board type which support S13,S14,S14 SR20, late Z32 and KA24DE ECUs. the same types of ECU that bikirom supports. but these are NVRAM like with the Z31 you have been using
currently the first board has been tested on S13 during several tuning sessions by PL and driven 600kms last weekend and undergone some durability tests. PL is quite happy with it
when i have S14 and S15 tested successfully on the bench (maybe S14 tonight?) we will get some more PCBs made and will require testers to use NIStune with these boards. should be within the next month...

SR20 require header pins or special cables connected to an external daughterboard. these are quite different to other nissan ecus as they use a Mitsubishi 77xx chip rather than Hitachi 6802/6303
yep once the boards are ready i'll post more here. i've got some firmware updates still to do and several more ecus to get working. having some troubles programming the S14 currently
