I have a 4 speed, so I couldn't care less. sounds like I'm the only on running their Thumpr cam.ġ) stall depends on which cam you buy (there's like 5). Attach that datalog here and we'll take a look.Hmmm. Highlight the entire map and subtract 15% from every cell.Īfter those checks and adjustments, turn the key on, start a datalog, start the engine, and assuming it is idling acceptable let it warm up for a few minutes. You could rescale it to stop at 100 kPa and start at 20 kPa, assuming it's not boosted. I assume you don't have a boosted engine, but your Base Fuel Table axis is setup for it. I'd save it as Sniper 4150 four injector and or call Holley to see if they can get answer it. I don't know if we've found an answer to the Future 11 question. If an injector is sticking it'll be obvious with an excessive amount of fuel until the fuel psi bleeds off.

To inspect the injectors, have a helper turn the key on while you watch the fuel prime shot at key on. If you need to cycle the key many times, unplug the fuel pump relay. Cycling the the fuel pump many times will cause your problem, a malfunctioning injector will cause that issue. Before we get to that, what led to excessive fuel in the oil? Having an extremely rich jet/fuel map will not usually leave liquid fuel in the oil. There's a lot that's not ideal with your GCF. Please also tell where my mistakes are so I can improve. Would kindly ask for some help with it before the startup in order to ensure I don't get in a situation to drop the oil again. With that out of the way I tried my best to create a reasonable safe map to use.

Would like to confirm that is correct for Stealth 4150 4 Injector.Ģ. When I downloaded from ECU the default map my first concern is: In the EFI Parameters the System Type if Future 11(screenshot attached ). That did bring me to almost a quart of gas in fresh oil. Loaded the Street/Strip map and the mixture was unbelievably rich. Now this beauty of a machine came up with an 4150 dual pumper that served me well for two years, but as my carb knowledge is not the best, thought I'd go stealth 4150 Sniper EFI for the cold starts and all.ġ.

This is another case where a beginner requires your help and I'm grateful for it. Hope you all are enjoying a nice weekend.
