Message	here. That tech spec you showed mentions the ECU clock chip as a "EXO-3" model including the 15.. Well apparently there were several versions of this chip manufactured which run at different clock frequencies which should mean different receiver baud rates. Man this brings me back to my old BBS modem days with my 1200 baud Hayes lol. [ http://www.chipdocs.com/datasheets/datasheet-pdf/KSS/EXO-3.html ] [ http://www.datasheetcatalog.org/datasheets/37/214299_DS.pdf ] Anywho - I am going to crack open my ECU and take a look at which EX0-3 chip I have. It should be that 15.360 MHz. chip. _____________________ 2006 Scion tC (Sold) 2004 Yamaha YZF-R6 (Sold) 2003 Nissan 350Z Track (Sold) 2000 BMW X5 4.4i 1993 300ZX Twin Turbo 1985 Nissan 300ZX NA (Sold) WE350Z at gmail dot com http://WE350Z.com
