Re: FYI info for Walbro ECU

Well, I think ECU-C is the stock ECU. It looks like it in the drawing.

Re: FYI info for Walbro ECU

from my understanding I thought the stock ECU parameters couldn't be changed... or am I wrong?

Re: FYI info for Walbro ECU

That drawing is straight off the old Walbro ECU site. The ECU-C is what Redline has stock. Purchasing a new one without a new map or the ability to map is just replacing the one you already have. I'd be interested if they can do anything else, but it looks the dead end I took on my way to the Vi-Pec.

There are a few things you can change, more related to service. As Ronnie says, it's a dead end, as far a performance changes. That may be because of the service software we have. (?)
If we had a copy of the development software ....
