550cc injector swap issues
 

Morning all,

Wondered if any one with denso 550cc injectors and either MS or speeduino ecu, could share their injector settings?

Using the injector dead times I have been provided leads to inability to idle and rev hunting.

In tuner studio I have reduced the required fuel to 4.8, dead time that I was given was 0.6 . If I change this to 1.0 like stock I can idle and there no hunting.

this is on a 1.6 92

Cheers!

Might not be the best advice but just pick a dead time that your car likes best.

I just installed new bosch EV14 640ccs and my car didn't like any of the settings given to me on the data sheet. I just tried what worked best and it runs pretty well now.

If you can't get your car to leave idle or a rev without stalling or idling at 13.0, Matsie, you probably shouldn't be offering tuning advice to fucking anyone.

jdmtom, quit buying fucking junk ass injectors. Nobody is going to be able to give you settings for some random ass set of generic injectors. As an example, go pop denso 550cc into google image search. Which of the millions of results are yours?

Mine are ksm Motorsport ones

Those are not genuine. I was looking at a set of those as well but found out those are fake

That's annoying. My tuner linked me to them as he had previously used them on his car

they might work fine for now but injectors are just something you don't want to cheap out on, especially if you're planning on boost.
