Will 14.4 ohm impedance cause issues with QD's in stock ECM???

Bascially all I wanna know is what the subject clearly states.....will an injector with a 14.4 ohm impedance (Accel Injectors) cause issues with the QD's in a stock ECM?? Considering the stock injectors have a higher impedance!!

Hey, that's my question

I've emailed Mr. Gasket about this, but haven't heard back.

The 14.4 ohm impedance will not cause any harm to the ECU's drivers. The reason for Accel using this particular impedance was twofold, (1)It is within OE specs for multiple applications thereby allowing these replacement injectors to cover a wider range of vehicles and (2)It will allow for a slightly quicker "rise" time especially at low pulse rates.

I noticed this too with the ford SVO 24# injectors. They run in the 14 range while the stockers run 16. I had no probs yet.

That's definitely good to hear from someone using the SVO 24 lb/hr injectors because that's what I've decided to go with!! I found a place online to get a set for $210 + shipping! :-)
