Hey guys,

Doing a little experiment with the combonation that most LH2.4 c900 tuners use for more fuel, which consists of 30# injectors and the 300ohm resistor to make the injectors cut away a little fuel at idle. I was talking to my local indy SAAB mechanic, and came up with an idea that can make fueling a little easier for those who already have the 30# injector/300ohm resistor combonation on their LH2.4 equipped vehicles.

Quick question...
What % of flow is eliminated by the 300ohm resistor in the AMM orange wire?
Eg; does 300ohms cut '10%' of fuel from the 30# injectors over the entire power band?

Which way would be best to dial in a little extra fuel? Is it needed at a specific RPM (4k, 5k?), or would a specified boost level be better to add some more fuel? Maybe around 10PSI, etc? I wouldn't have the capability to do both RPM and boost with my limited electronic skills.

Anyway, any help would be appreciated.
If it works out, I'll be able to post some information that might help leaning out on the top end, with any tuners who have this injector/resistor combonation.

thanks,
Taylor
