Changing injectors on modeled tune ?


oversteer

Recommended Posts

Hello

Planning to start up and run in a new motor shortly, I have fitted 60lbs hr(630cc) Siemens Deka injectors to run engine in, and then power tune will be using 2450cc Siemens Deka's on E85(car will be flex fuel, has sensor fitted).

Question is how much re-tuning is involved with modeled fueling when i change the injectors ? 

Would it be quicker to setup the run in tune(will be on 98) with traditional fueling tables and go to modeled multifuel only when the final larger injectors are installed ?

Cheers

if you tune it in modelled first, then change the injectors, as long as you update the tune with the new injector parameters it should still run moderately well. It wont be perfect so probably not worth getting it perfect on the smaller injectors though.

Any one got any injector data for the Siemens 220lb FI114212 injectors ?

These are  2 Ohm injectors, this ok with Thunder with no modifications ?

Yes, the Thunder will drive these no woories.  Set injection setup to Peak & Hold, 4A peak, 1.5A hold.
