injector resistance
i have smartfire 120lb low inpedance injectors. im using the stock ecu with some load resistors so i dont ruin my injector driver. i just ohmed out my setup and the injectors alone are 3.5 ohms and my resistors are 6.7 ohms. thats a total of 10.2 ohms. stock injectors are 12.3 ohms. can this ruin my injector driver in the stock ecm? how will this resistance difference effect the way it runs?
i ask because my truck shows its super lean at idle. i add fuel and it wont even start and sometimes it will barely start but only if i have the foot on throttle and the afr's start to show up but not entirely. is the difference in resistance screwing it up or are these injectors really that bad? i am running e85 and the flow rates are correct and my stoich is adjusted to account for the more fuel and i have overlooked the tune many times and it shouldnt be running like this just because of the tune.

Did you read about all the trouble that these Chinese injectors are causing. It's not the ohms it's the injector. Get them flow checked I bet they have 25% variance across the set
