ECM mods-377 Scorpion
 

Customer is taking delivery of new 28 Donzi with twin 377 Scorpions. He is adding CMI exhaust and wants to reprogram the ecm's. He called Arizona Speed and also Teague,they both said all they do is big blocks. Does anyone modify for small blocks?

If they are the MEFI 3 ECUs, Tyler Crocket will work with you. It's just that no body does much modification on the small blocks so there are no canned programs. They just have to tweak the fuel maps, which is trial and error unless you have it on a dyno. If those engines are Smart Craft (PCM555) Whipple is the only one that can reprogram them and they won't touch it. They don't even have the supercharger applications sorted out yet for those ECU's.

hey magicfloat can you get me a big donzi sticker for the back window of my truck we dont have a dealer here in atlanta any more?

Mikev,I'll check to see what I have.

Thanks magic, you going to be at the atlanta boat show this year?

Unfortunately,no. We always visit to check everything out but since I'm temporarily in a wheelchair from an auto accident I'll have to skip this year. Bham show is Jan 28-Feb 1,we will have all of our Formulas and Donzis there. Come on over,it is a nice show.

Try the FAST system, with a wide band O2 sensor, and a lap top you can tune the system in the boat, on the water.

Whipple has a supercharger kit for that engine so I'm sure Dustin can help with the ecu.
