Re:DSM Injectors not compatible with Honda ECUs..
I am in no way an authority on this. But it seems that depending on year of injector there can be a big range on ohm readings. All I remember is that there 'appears' to be no problems on the low 3-4ohm ones.
HT had a good discussion on this.

So you think it could be because my injectors are 2.7ohms? does anyone know what the resistance is for stock Honda 240cc injectors are? or can they have a wide range from the factory as well?

Re:DSM Injectors not compatible with Honda ECUs..
Damn seems like I'm having the same problem to 
Just got the motor dropped in, and the car is cranking but not turning over
Onyx thinks its timing, I think its the fuel delivery.
Has anyone here had the injector set up work WITHOUT upgrading the fuel pump?
What were your AFC settings?
Thanks

Blue top 450's
like 3.2 - 3.7 ohms on all.
Hondata on stock pump at 50psi FP.
Starts every time so far. (only been a few days)
When you car does run, does your idle hunt at all (600-900) or does it idle a little high? (900-1100)

Re:DSM Injectors not compatible with Honda ECUs..
it isn't turning over It's cranking and it got a little thump going and then died right away.
My stock fuel pump has like 90k miles on it to and might be going out a little. I'm thinking that maybe there just isn't enough pressure right now for those peak/hold injectors to spray where as the factory honda ones are saturated and slightly open all the time right?

Re:DSM Injectors not compatible with Honda ECUs..
my blue top dsm injectors are 2.9 ohms all 4 of them
My other set of stock ZC 240cc injectors are 2.5 ohms all 4 of them.
I still have to put the DSM in jectors in my car.
Have them on a cleaned spare intake manifold gonna swap the manifold's soon.
