this is my deal.i have a haltech e8 running a third gen in my rx2.850 Siemens primary with 1600 Bosch gray top secondary.the primary injectors have 2.5 ohms and the secondary injectors have 4.7 ohms.this is almost two times the resistance in the secondary injectors.the secondary injectors are setup in the common mode.the injector current is set at 2 amp peak and 0.5 amp hold.in the injector current setup i am not able to split the current from the primary to secondary (meaning i would like to apply more current to the secondary injectors).i would think with the secondary injectors having more resistance they would need more current to work properly.one current setting is applied to all the injectors.this is what i did over the long weekend to find were i am at now.i will try to make this as short as i can.made a couple of dyno pulls Saturday with no usable numbers.pulled the car home.removed the ngk11.5's these plugs are hard to read because they are so cold.put ngk heat range 8's low boost on gas(ran out of E85)made a couple of street pulls.broke the porselen from the #1 rotor plug and trailing looked lean.ok cheap plugs.went back to the E85 maps.got E85 put ngk9's in.made a couple of street pulls and the porselen was gone from the #1 leading and the trailing looked lean.#1 is running way to lean.i added 5% to the primary and secondary injectors in rotor #1 in the injector trim map.installed the nkg 11.5 plugs.ran the car for one last street pull it made a complete pull with out a single problem it has never done this.i have my egt gauge after the turbo.now i know why all you smart guys have two egt gauges,one for each rotor.i have another egt gauge coming from summit.after i install the egt gauges at each rotor, i hope i am just a few clicks away from a good tune up.if this were your car would you send out the injectors to get them flowed?is a good injector shop able to check injector dead time?(the delay from the coil in the injector to react to the current applied?)could this be part of the problem?still feel ignorant but learning as i go!!any and all words are welcome.

 

The rule of thumb is:

2-4 ohms = 5A setting
4-8 ohms = 3A setting
10+ ohms = 2A setting

When connecting 2 Low Imp injectors to one output, always choose the 5A setting.
