Title: WTB: Magneti Marelli IAW 441 p8/P07_46 replacement?
Post by: bputney13 on June 19, 2026, 11:27:00 AM

Anyone have a replacement or upgrade for my burnt Magneti Marelli IAW 441 California 1100 p8/P07_46 ECU?  I may send mine to Carmo for a diagnosis/fix.

I have a MyECU from AU , it reads Microsoft word. It is the ultimate for the replacement. I also got a used one from Ebay.
Cliff Jefferies and I are about the only Cali's running it so mapping I've done myself.

I still have the one from my ‘96 Cali from when I replaced it with a 15M from a later Cali. PM me if you’re interested. It was working when I removed it. 
But It never ran good with the P8 factory map burning modern fuel with alcohol.
There was a hack where you put a resistor with the temperature sensor to make it read colder and run richer.

Hello, I've a new  ECU IAW441 for California. But I think the shipment cost to USA are too high. Write me in pvt if interested.
