Fuel injector resistance obd2 JDM h22?
Long story... I'm rebuilding the h22a I swapped into my lude a few years back due to some blow by on the piston rings I was starting to contend with... When I swapped it originally I used the new injectors on the h22 for the higher cc etc. Now looking at it I completely overlooked the resistor box for the old injectors still installed.
The question I guess is what are the problems you can have from leaving the resistor box in on high impedance injectors? I know lo impedance injectors with no box can damage the ecu, this is the opposite scenario which im having trouble finding info on.
Plus I didn't feel I was lacking power for the 2 years it's been daily driven after the swap, I checked the injectors im using from the jdm h22 they are 11.2 to 11.3 ohms and the cars been running strong that way, gets out of its own way pretty well, regardless that the resistor box is still installed.

it shouldnt damage anything by leaving it in, but it will definitely run better without it. you can either cut the plug off the box and just connect them all together, solder, and tape it up well, or get a spare box to do it to if you dont want to cut yours. it's wired on the power side, which has power at all times when ignition is on, so there's no worry of the wires staying seperate. they can all be joined to one solid blob lol.

Thank u for this info i had same question. And i did what u said and i noticed a difference in power. So thanks again. And i keptkept my box just did what u said 😎😎
