I have an Accel DFI 6 ecu with a RS harness and Toshiba Laptop for sale. The RS Harness allows you to direct plug and play in to the factory harness if you have a 305 with a T-5 Trans. The harness allows for the stock ECM to run the emissions side of thing while the Accel does the engine functions. This set-up will also come with a stock ECM. Also on the Accel software disc I have multiple saved tunes. Some of them were done with 101 octane race fuel so be careful of the timing. This system has worked flawlessly for me I have won 8 National Championships on it. Over the winter I upgraded to Accel DFI 7 with a wide band. This could all be yours for 400.00 plus shipping. PM me if you are interested.
Thank,
Mark

I am very interested, but I would like to tune with a wideband o2 sensor.
With this ecu I will not be able to do that?

 

I you can get an external wideband for tuning and I think Accel had an adapter for the 6 but you should contact an accel dealer to be sure. All tuning should be done on a load bearing dyno for best results and all of those have a wideband that is how I tuned it.
