Individual runner intake ECUs

[Tom]

Has anyone had any experience using individual runner FI intakes (TWN, Kinsler etc.) ? Specifically, I’m interested in the EFI units used to run these IR systems.

(Notes: Motor is an early SBC. Looking at IR systems for the visual “pop” over TB systems.)

I’ve been reading and talking with as many people as I can and this is what I’m hearing:



Electromotive: good, but hard to set up and work with, poor support

Accel DFI: good overall, but hard to get to work w/ IR systems b/c needs a MAP sensor and it is difficult to get a vacuum accumulator to work correctly with 8 throttle bodies. (Apparently Roush had a lot of trouble getting it to work w/ their new IR crate set up.)

MoTec: the best, outrageous price, overkill for most street applications

I appreciate your thoughts.
