Default EZK interchangeability LH2.2

Need to replace my ICU 1989 B230FT LH2.2 with 541 ECU and 012 EZK

Does anybody know if Bosch 0 227 400 148 EZK is interchangeable with my 012??

Cheers!

The 148 EZK ignition box is lh2.4 not 2.2. I've never tried it to see if it would work but 012 is what is turbo lh 2.2 EZK ignition box.

Who knows what would happen if you plug it in? Smoke? Maybe it would work? I'd check the schematic pin outs on the connectors see if they match up with each other before I even tried. Who knows?

^^^ someone must have had too much fun this weekend....

LH2.2/EZK117 uses a pulse-per-cylinder hall sensor in the distributor. LH2.4/EZK116 uses a 60-2 flywheel and CPS. There's no way that they'll interchange.

Yea the pinouts are different. Won’t work.

Check eBay or post in the wanted section for another 012 EZK box.

Even more important is the sensor triggering the unit is different. LH2.2 units use a hall sensor and the LH2.4 unit uses the VR sensor. I usually shop ebay. That is if you can't find it by looking in for sale or put a request in the wanted section.
