TBI on scout II- Please help!

[Dlxman]

TunerPro RT can provide an enormous about of information, see screenshots below.

Many years ago, I experienced frustrations with a fuel only aftermarket TBI system on an IH 304 Scout. I installed a DUI HEI distributor and the Scout came to life when the 1227747 was controlling spark. TunerPro RT "Recorded" or data logged the Spark Advance (Hack Required) and Fuel BLM's (Rich / Lean).

Data = Performance . . . the absence of data = frustration

Hi Dave, I have been trying to locate the "Hack" for the Tunerpro Spark Advance as you noted. Can you please provide a link to this?

The .bin file or chip is modified using TunerPro to enable the "Hack"

Are you setup to burn chips with modified .bin files?

I am not set up to burn chips.

So I guess I will not be able to datalog the base pulse width or the spark advance..?...

A custom programmed PROM chip with the "Hack" is required to data log BPW and SA.

Perhaps you have a spare chip, and maybe another gearhead-efi member will program the spare chip for you with the "Hack"?
