Hey people, i have a peripheral ported N/A 13B Mazda RX7, a '90 Gen II. We have a Mircotech LTX-12s fitted, 4x RC 750 injectors, 4 x Gen3 FD coils. All
sensors are ok and correct, no fault lights on.

I'm having an issue getting the car to fire up. I have set the ECU to the
setting stated in the manual.
Config: 4cyl
Imput trig: + POS
Output: -
Dwell Type: Time
Dwell : 3.25ms
Pump Dwell: 3.50ms

Now when in config and set to test all injectors fire fine and all plugs
have good spark. Timing is set up to stock configuration. And i have good
fuel pressue in the lines. The problem i'm having is when i crank the
engine the injectors arn't firing at all. No fuel is comming out of them.

The ECU was on a 20B n/a before. I was hoping that you may be able to direct
to 'master' reset so i can start over from scratch. Alturnitively is there
a way of telling the injectors to stop firing? maybe something have been
altered by mistake. I do have the dash unit fitted in the car.

Any help would be very much appriciated

 

Send the ecu down to aus and have it reprogrammed for 13b.

pm me for more details.
