TazzEp91 Posted November 22, 2016 Share Posted November 22, 2016 (edited) Looking to purchase some denso 560cc injectors for my glanza theyre high impedance will they fit directly into my car?Cheers Taz Edited November 22, 2016 by TazzEp91 Quote Link to post Share on other sites
Stu Posted November 23, 2016 Share Posted November 23, 2016 Physically yes, but you need to be running something other than factory engine management to tune them. Quote Link to post Share on other sites
TazzEp91 Posted November 23, 2016 Author Share Posted November 23, 2016 Yes mate for now im running a greddy emanage bud Quote Link to post Share on other sites
Nafeez2125 Posted December 28, 2016 Share Posted December 28, 2016 How much horsepower gain for swapping Injectors and the emanage mate? Quote Link to post Share on other sites
roachburger Posted December 28, 2016 Share Posted December 28, 2016 Non .. there is no horsepower to gain just by swopping 4 injectors, it's more than likely you will loose power.An injector works by a voltage signal being sent from the ecu. Each voltage corresponds to a pulse time and flow (duty cycle) telling the injector how long to open for and how much fuel to flow.If you go putting a larger injector into your engine without programming the pulse and duty cycles the ecu will presume the injectors are the same flow and not make corrections for the amount of fuel.I.ewhen a standard injector flows 295cc @100% duty cycle at w.o.t and full boost (6psi),That's all kinds of good fuelling. If you take an uprated injector that flows 550cc @100% duty cycle and the ecu asks the injectors for 100% duty. Well, you can imagine the outcome. Quote Link to post Share on other sites

Nafeez2125 Posted December 28, 2016 Share Posted December 28, 2016 I know that maybe I didnt ask the question properly, my question was what is the power gain after swapping the injector and fine tune the emanage for that particular injector. Quote Link to post Share on other sites
Phil Posted December 28, 2016 Share Posted December 28, 2016 I know that maybe I didnt ask the question properly, my question was what is the power gain after swapping the injector and fine tune the emanage for that particular injector.Your still not asking the right question Again the answer is no power gainUnless you change something else to require that extra fuelling potential Phil Quote Link to post Share on other sites
SpikeyJp_68 Posted December 28, 2016 Share Posted December 28, 2016 More boost + more fuel = more bhp Quote Link to post Share on other sites
Nafeez2125 Posted December 29, 2016 Share Posted December 29, 2016 Your still not asking the right questionAgain the answer is no power gainUnless you change something else to require that extra fuelling potentialPhilHi Phil, Sorry im not arguing with you im just trying to increase my knowledge. when you said something else you mean an uprated fuel pump or is there some more things that need changing?

Your fuelling just needs tuned to match the air flow.So you need more air if your going to make power from Additional fuel.Phil Quote Link to post Share on other sites
5e colin Posted December 29, 2016 Share Posted December 29, 2016 More boost + more fuel = more bhp = less boost less feuling keeps longer engine ha ha ha ha Quote Link to post Share on other sites
SpikeyJp_68 Posted December 29, 2016 Share Posted December 29, 2016 = less boost less feuling keeps longer engine ha ha ha ha Come on Colin, we all know you're not having fun if you're not running at least 4 bar and maxing out injectors :P Quote Link to post Share on other sites
roachburger Posted January 1, 2017 Share Posted January 1, 2017 basically ....we cant tell you what power you will gain from injectors and a mapping session for multiple reasons:-1. the air temp on the day does effect how much power you will produce allbeit a small amount 1-2 hp sometimes 5 max(i work very closely with canems ecus and his dyno is actually at my work, ive seen first hand a hp figure change from first thing in a morning to mid afternoon when the air is hotter ettc)2 your general engine setup, clutch, flywheel, gearbox, boost level, engine health, plugs,fuelling3. what fuel your using and where yoou got it from4 the mapper himself/herself5 the dyno.the list is endless and can get even more tedious but iirc about 260/270 is easily producable on a td04 4e with injestors and a good map.
