2002 L59 Flex Fuel OK for swap?
 

I have done quite a few swaps but none with L59 flex fuel option. The engine I am considering is a 2002 L59 with low miles

Is there any special consideration for the flex fuel option as it relates to an engine swap?

I read that there is a sensor that measures the amount of ethanol in the fuel and adjusts accordingly- and that the PCM defaults to a standard setting if the computer does not get a reading from the sensor.

Is this something that is addressed in the PCM tuning?


I will just use regular pump gas as always and do not need the flex fuel capability but do not want to throw a code that puts on the check engine light

Thanks for suggestions

I did one, no issues at all.

Honestly it seems worth it to just get the sensor from a donor and hook it up. Its not an immensely complicated piece, and allows you to run 87-93 straight, low-E blended (common) gas, and E75,85,90.
