I am wanting to see some fuel maps for a 13b bridgeport turbo. I am getting Two "peaks" in my map one in the acceleration part of the map and one obviously in the upper end in boost. I am getting rich AFRS in acceleration 11.8ish i can still pull fuel out but am having a hard time making adjustments not going too far one way or the other. Is it normal to get big changes with 1000cc injectors with small adjustments? Is it normal to have two peaks or am I over thinking?

 

Do you have a .msq file?
Could have something to do with injector parameters, dead times / battery compensation / something like that.
Also my experience is that a wideband o2 sensor is of limited use with a high overlap rotary engine such as a bridgeport or peripheral port.
During lower loads the overlap causes the engine to misfire, this throws off the reading and the raw fuel being dumped in the exhaust quickly kills the o2 sensor, so it could be that the issue is actually measuring the afr.

 

I think I figured out the rich acceleration problem, too much time in accel enrichment.

 

Widebands, I am told, actually work well in a misfire situation, because the internal element catalyses the raw air/fuel.
Otherwise they would be thrown off by incomplete combustion, which rotaries have a lot of!

 

Can confirm by flooding the engine at start up.
