yes. large injectors + minus fuel = advancing ignition timingwhite_bird said:heard of it but dunno whether it's true or not.. anyone??
not necessary. some to save engines, some to spool up the turbine. different engines have different approach. if you want maximum hp, you need max torque. to get maximum torque, the maximum pressure created by combustion must occur after certain degrees of ATDC. this is where the pressure will push the piston down, `faster'.white_bird said:erm.. wad i been told retard the timing during hi boost can increase some hp right?? can any1 elaborate a bit??
so confirm la kalau -ve at safc= advance timing...Battousai said:Generally...
If SAFC set to -ve, then ignition advance
If SAFC set to +ve, then ignition retard
If you go to a bigger turbine, both of what you said can work, depending what car ur using.
The best bet is to pay a couple hundred bucks and get a good dyno tune.

will it affect the settings?
i am experimenting the same thing oso. Increase the fuel pressure and -ve the SAFC. Same case with you... no dyno in Penang .. :( so have to experiment with an autometer AFR ..stroker_kit said:so confirm la kalau -ve at safc= advance timing...
thanks for ur info...
so now, i'll try to increase fuel pressure and set my SAFC to -ve.... cos i tried set +ve at Safc, my engine feels very heavy la...
p.s: if sarawak got a dyno machine, i'd be the first customer to tune my car there......heheh..

haaa...this is what i meant.. now im back to square 1...:frown:4wdGBox said:isit true?
as we set to -ve means less fuel, lead to lean burning, when lean got knocking, when knocking got timing retard this is what i know la...
