Reducing injector size and removing ballast packs

Recommended Posts

Planning in moving from 650cc low impedance too feel injectors and ballast packs from my car and fit sensible 565cc high impedance injectors as only running around 68% injector capacity at present on 1.65 bar of boost

 

do I increase the master fuel from 10ms to about 12ms till I get a retune and be able to drive it to the rolling road 

 

ps is it worth fitting an egt gauge in the headers before the turbo or after it

Yeah, you will need about a 15% increase in pulsewidth.  So the two options are increase master fuel as you have suggested (that will give you 20%) or just highlight the whole fuel table (click top left corner) and type in "+15%"

Edit: Missed the EGT question.  It is more relevant before the turbine as that is more indicative of combustion temperature.

have done that and seems to be running better since moving away from the low impedance and ballast packs
