Have a few customers going Ignitron(best plug in stand alone ecu on the market).

I made these custom, ready to install harnesses w/sensor for them. This got them quickly, simply and effectively installed and immediately functioning.


They now the ability to run from straight pump to a full E85 map with accurate and intelligent blending in between.

E60@25psi 90* ambient temp

Pagparts v1 billet gt3071r
No timing added from my pump gas file, I did turn off my DI meth. 96% DC for injectors lol.

Ignitron ecu.


Check my Instagram for video proof and video of the pull.

Genesis2 1000cc with an oem 4 bar FPR and OEM 4 bar MAP sensor.

In Ignitron, in the basic settings tables drop down, go to inputs. Over on the right, digital(freq) column of items, first one, check the box for ecu61 and select "fuel ethnaol content" in the drop down. No pull up resistors, it's a pin in harness into the large ECU connector.


Also, they are banned but easy to search and find info by OP and their contact info.

Many thanks for the reply. I have the FF sensor pinned to #38 and do not get a plausible signal from the sensor. I thought not having the pull up resistor would be the culprit. I get the following code:

X0023 - Fuel content sensor range/performance/incorrect signal
Intermittent, frequency: 5, duration: 7
RPM: 847, load: 34.0%

Now if the pull-up resistor is not needed, I am puzzled as to what may be the cause... I do have the sensor downstream of the fuel rail, so in theory I could have aeration/bubbles after the FPR, but the signal is corrupt also when I shut off the in line fuel pump, or turn engine off altogether, so it would point to either having a faulty FF sensor (new unit) or something not right in the sensor setup in the software side. And yes, I have triple-checked the wiring good sensor ground from ECU, 12V OK, and signal wire to pin in the correct slot #38 (I have EGT sensor in #61, -works fine). Also the sensor frequency table for EtOH control is correctly set as well as the pulse width for temperature. Any ideas are hugely appreciated.
