Thread: Anyone familiar with techtom 377a daughterboard

My s13 apparently has a techtom 377a daughterboard. Is anyone familiar with this daughtboard and if i can use tunercode or jk tuning software to tune it. Or the model of eprom chips it uses. Thanks i have a moates burner and i am hopinv to be able to use this board with the above software. Thanks

Like this board? http://www.sr20-forum.com/tuning/50603-big-value-special-engine-builders-gti-r-ecu.html

In any case if its a S13 ecu daughterboard, it will have 2 eproms. Maybe setup as same on both or odd/even it doesnt matter. it will be 2 x 256k or if they are 2 x 128k its deff odd/even. Its easier to get 512k chips now, and they are pin compatible with the 256k's

you will have to be able to remove the eproms, some ppl glue them in place, a heat gun will help with that. After removal you can replace them with flash eproms in sockets or burn over the originals if you have the technology.

You can then load any S13 bin(factory type) or the tunercode version(purchace from Dave Dunn) for the S13, use Nismotronic(from JK tuning)[or tunerpro RT, free/shareware] to tune tunercode bins and Tunerpro RT for all factory type bins.

Nismotronic has been set up for tuning tunercode specifically, It doesnt do other bins like the factory stuff.

If you want realtime tuning then sell the board or whole ecu and get the $550 NEMU package. Nistune is also an option for realtime tuning but the NEMU is much more powerful for the S13/B13 ecus in what it can do currently and what it will be able to do in future.

I have one that's socketed, so Programmable Chips could be used with it to run TunerCode.

T has the dual chips that are uv light erasable. I think i will try to sell it on zilvia or some such and pick up a nemu as i already have tunercode.
