He has the wrong ECM for an airflow type system. It is running way to lean and is in limp mode due to that.
A missing knock sensor will default to the last good timing curve, which should provide little if any performance deficiency (noticeable).
It will not force the ECM to run in limp mode.

The 16198262 is not compatible as it is SPEED density not AIRFLOW density. No MAF input is why it is lean and pingy ...etc...runs crappy when cold.
Definitly dont run the 16198262.
An 16198259 is a direct replacement compatible number for your ECM, of course the prom may need to be changed, or get a new one burned for your upgrades
you need a knock sensor if you want the best performance overall and to protect your engine.Dont overlook it.

Also check for a stuck open EGR valve.

|DoubleVision||I would think getting a knock sensor for it would be the first step in the right direction to help get the ping under control before it destroys the engine. Make sure you get one for the 305 engine as the sensor must match the cubic inches.|

t p i pinging problem 305 engine
hey guys.need help badly.havea 34 ford with a 1986 305 tuned port engine that i just purchased,my problem is it pings,even with octane boost.it has the plug for an knock sensor,but none installed.it has maf.
engine serial #v06c2dda.which tells me its out of a firebird.the stock ecm
is supposed to be-1227165,but it has a 16198262 .anyone know if they are compatable?it runs fine,except for the pinging,but also needs 10 minutes warm up time ,or it stalls.mabe a different problem but would like to solve pinging befor she goes away for winter storage.any ideas would be appreciated greatly.
