How do i find out what model number of ecu my 1988 RX7 with a 13b n/a has...are they able to be modified with an after market chip or is something like an apexi safc the way to go?appreciate any input guys and as always i thank you in advance!Dave

 

it should be an n326/n327. safc is the way to go

 

appreciate the reply J9FD3CS..I've been lookin at doin up my 13b n/a...right now it is stock (p/s and a/c removed)...so I'm steering towards a little more bang.I know go turbo..eventually... but I'm researching doin this and that to an n/a..and one of 'em on my list was ecu or safc ..just another quick one if I may ( i have located a ecu with a performance chip but wanted to know if the ecu is reliable with it or just a piece of crap.In all honesty I was going to throw on an APEXI SAFC until i saw this ecu)..what else would be required besides just the SAFC unit itself..any special type of O2 sensor..(ALSO clipping on CRANE HI-6)(other mods along with this would be cone style intake set up and a better exhaust which will be designed by me ..duals)again any input at all is highly appreciated on this end ..thanks!!!!
