send your ecu to us and it does :)


works great for the edelbrock kits. seconday injectors engage with vtec. as pictured for saturated injectors, but add a dropping resistor and no prob with low impedance injectors.

Great! Do they 'accept' the same pulses with the main injectors? I mean if the tables command for a 5ms pulse, I guess the secondary's will also accept a 5ms pulse, right?

exactly. we recommend using your larger injectors as the primaries and then adding the secondaries with vtec. if it is a non-vtec app you just disable the vtp and vtec sol and use the vtec map on the non-vtec application. if you are semi-tuned and add the secondaries you just multiply the vtec map by (old injector flow rate)/(old + new flow rate)

example: for edelbrock kit with 310cc additional injectors...
contol J, enter .44 in parameter window with entire vtec map highlighted.
i add 10% back to insure a rich map to begin tuning with.

stock d16y8s easily and safely produce 210-220whp (dynojet) with the edelbrock kit at 11-12psi and hondata control of the extra four injectors.
