Sard 700cc Injector Settings

[png godzilla]

hey Guys,

now that my inj duty cycle is strapped i need to put the bigger injectors in.

i have them here, SARD 700CC (light Blue tops) but don't know where to get the Injector Latency figure for them so i can work out the adjustment factor.

444/700 = 0.634 so 63.4

0.772 - (new Latency unknown) = Correction

any one got a figure or a link?

surely someone is running SARD 700cc injectors with a Power FC, i just need to know what perameters to put into the FC so i can run them?

i have a wide band O2 sensor in car to get the A/F's right, but could really use a link or some information on changing ignition & fuel maps.

no Dyno in Papua New Guinea & no one with aftermarket ECU tuning experience....................just me!

would really apreciate any help

whenever i need lag time settings i just google them

hey Beer Baron, i'm all googled out , but i have been searching using SARD & LATENCY in every which way i can think of. are you saying try SARD INJ LAG Times?

i'll try that i guess

hey Beer Barron, you da man, "LAG" is what i should have been using. easy when you know how eh?

put the injectors in last night, running good even with std maps.

new injectors reading 68% at 1.2 bar under load where the stockers maxed out 100% at 5,500 in 2nd at same boost.

now all i need is schooling on how to change Ignition & Fuel Maps to smooth things out. i have a wide band O2 mounted full time, but want to knock the timing back somewhat to keep knock down as i'm forced to run on 91

know of any Video's explaining the proceedure & links? i did try Google, but failed me this time!

haha, glad i could help mate! I knew they were out there.

tuning is a whole other ball game though. basically you will need to spend a lot of time around the area that it's building boost really fast, and around peak torque. This area will have a propensity to be very sensitive to ignition advance. too much and it will ping/knock, not enough and it will be a bit sluggish and not build boost as fast as you'd like. this area (transition to boost) is crucial to getting a nice drivable car. basically you want to be getting the AFR right, then work on the timing. raise it until it knocks, then back off a few degrees at those load points that knocking occurs at.

and ABOVE ALL: BE CONSERVATIVE!
