EFI Any Manufacturers for the Shee?

[blowit]

I would definatly be interested in talking to some one on those units....

 

I use the old ecu stuff with out closed loop and get by fine once you get it dialed in there is little need for it for racing unless you make a bunch of changes on the engine we ran for many seasons on or little 250 micro just using the efi as a altitude/temp compensator

All our new race care use closed loop and data loging ...it sure the best way to go by far and it aids in getting the mapping dialed in and you can tell what happens when things go wrong

 

But in all reallity if you just need a very precise electronic carb just a simple open loop system works wery well

You caint beet EFI for runing and tuning methanol burning 2 strokes What we found is the abillity to lean the mixture down for max power but still have the consistancy and safty on runing a carb rich, actually much more consistancy because you eliminate the posibility of sucking the bowls dry.

 

 

I agree on alky. So much fuel being dumped and vaporization of the fuel is just so much better with higher pressures of injectors. Just getting all the slick features while holding the price down is going to be tough. Injection is just the only way to fly with boost and NOS so for full race guys, it is a no brainer but the simplicity of carbs is still appealing to many.

I am not sure what sort of racing we are talking about here, but I am pretty sure I am going to have to disagree about there being no use for open and closed loop mode in racing. :ermm:

Oh haha let me restate that...What I ment is closed loop is not 100% needed for every aplication

You can get by with just a simple open loop for say a banshee, If your looking to keep the cost down.

The wide band O2 is nice but its added cost
