Injectors Duty cycle

[Eddis]

Hy everyone

Does anyone knows if the stock evo 8 engine with stock turbine and injectors, will run over 95% of duty cycle, boosting up to 19psi to rev limiter?

totally free flow exhaust (no boxes at all) doing low 11afr..

Cheers

99% sure that they wont. Try it and see if you get fuel cut xD

In all honesty, get a tune. Domt just go cranking up the boost if the car isnt properly mapped for it. Also if you do a tune you can see where your power band is. Which i can almost guarentee you arent making power into redline on a stock motor with exhaust so no need to go that high.

This is a rally car, its using a walbro ecu (pain in the ass)

The exhaust its due to the ALS system, the car was running on 32mm restrictor and now its off,all the fuel map is new..
i made some calculations and the injectors are very close to the limit, if it was other ecu i could calculate the IDC or at least see the injector pulsewitdh, but in this case no..

Thats why i made the question

very thanks
