I have 2 x 820cc (12A turbo) rotary injectors in the primary and 2 x 1600cc Bosch injectors for secondary and 4 x 1600cc Bosch injectors on top extra I want to run 2 programs on the Haltech E11v2, 1 for racing fuel and one for methanol not sure of the impendency of the injectors. Please help with Haltech E11v2 injector wiring and setup THX

 

for that setup i think you'd need to decide if you want to run the 3rd set of injectors together or not. i think if you wire it up individually-like, you can run sequential on the primaries and secondaries, and then the 3rd set would just come on all at once...



i'm not sure off the top about the impedances, you'd have to look in the manual, and measure the injectors

 

THX for the reply

If I run on racing fuel map1 I don’t want to use the top 4(1600cc)extra injectors just the 2primary (820cc 12A turbo)injectors and the 2secondery(1600cc)injectors but if I run on map 2 methanol I want the extra 4(1600cc) injectors to work. How do you measure the injectors impedances?

 

As far as I could tell you can't do that. All the 1600's will be secondaries, your first pair will be sequential, the other 4 will be batch fire, firing with injector 1. You can't shut off the set of 4 with the secondary map setup, you have to shut them off with your laptop.



Of course if you use a relay for the power supply to the 4 that is controlled by the same switch you use to change from map 1 to map 2 it would do what you want in a less elegant way.



1600 cc injectors are all the 2 ohm type. You can measure the resistance of the 820s with a multimeter, it's not the impedance, but it's close enough, and impedance is pretty tough to measure properly.
