Which ECU?? 700 1990

1990 740 with 2.4

I currently have the 556. I have changed all the sensors and cleaned parts and connections throughout the engine bay to no avail. Car idles great but revs between 800 - 1200 rpm when throttle is applied.

So off to the boneyard to find another ECU.

I have heard the 933 will work.

Any other models??

Thanks>
