How do you Reflash the EPROM?

NissanPower305 · 03-20-2005, 03:19 PM

I fried the transistor on my jwt programmed ecu and also the solder joints so my boy nick who works out of the avionics backshop unsoldered the jwt ribbon and soldered it to my stock computer. The only thing now is do I need to reflash the eprom or? More information at http://www.sr20forum.com/turbo/107357-turbo-problems.html

Can't do a JWT daughterboard yourself. You shouldnt have to either. Just move the jumper from CJ1 to CJ2 so it reads from the JWT board.

I already did that I just dont know if its making a good conection so I'll have to do a resistance check here when I get some time. Because I ran the car and now I get code 5,5 which is normal engine operation and my cobra maf tests good but still reads 2.58 volts when KOEO and idling so my ecu can't be reading that jwt daughterboard or something.

There is still something wrong with your ECU / wiring. The daughterboard does not affect MAF readings in anyway. It just contains maps and data.

sorry for being off topic, but which avionics backshop does he work in?

Were both from whiteman afb and he works in just the avionics backshop there is only 1 and then 3 flightline shops A,B,C. The injector resistors are wired in correctly I know that, the maf is now wired up correctly, but I still don't get why I get that high of voltage its only supposed to be .6 volts with KOEO. What about when its idling?
