As title, my ecu cannot run lows as its flyback components are not man enough, is it safe to run it through resistior packs (off of a nissan or similar) and how do these get wired (ie before injectors on +ve side, or after on neg side) advice would be graet on this please.
There are billions of cars worldwide apart from mine using resistors.
If it is mapped correctly with resistors they work 100% fine and have NO EFFECT, as any is accounted for in mapping.
The resistors go in the ecu feed(negative/switch) to each injector, it can be mapped perfectly with these, as 0.97% CO 137PPM on a 200K mile old engine(mine) shows, that could still crack 40 mpg and idle perfectly on greys, T34 modded head etc.

Not possible im affraid as i run high impedance petrol injectors, the LPG injectors im fitting are lows, and i think all LPG injectors are low impedance.

he uses megasquirt and you can make a heavy duty flyback board for that to run lows no probs, did that on all my previous cars, i think im going to use an audi ig amplifier to earth the injectors, if that does not succeed then i will just have to try resistor packs

so am i correct with my maths: using V=IR therefore I=V/R if my injectors are 4 ohm and my ressistor pack is 8 ohm then the current draw (with 12 ohms) will be 12ohms/12 volts= 1amp?
Which is the equivelent draw that a single 12 ohm injector would have. The 4 ohm resistors on thier own would be 12/4= 3 amps each! too much IMO, will the low impedance injectors still function as they should?
