Injectors 100% duty at 0.8 bar??? what the

[ricknismo]

GTR...0.85 bar 100% duty cycle...why

Injectors stuffed?

regulator?

any ideas?

[Wazz]

more mods may help some people reply

[ricknismo]

no mods...standard

[netrati]

How do you know the injectors are at 100%?

[pnblight]

what ecu and tune a/f ratios

[ricknismo]

34 GTRs have it indicated on the monitor

[sewid]

ECU is running the injectors at 100% to protect from detonation? Typical turbo car stock ECU over protective nature.

Could be wrong.

[ricknismo]

hmmm.. it runs full boost at lower revs at 50%..maybe your right.

I just hope 1.2 doesn't blow it up..hehe.

Am I game????

[sewid]

Mine runs 1.12 (indicated by the MFD) at full noise. No problems so far. I usually tootle around tho and it doesnt go far over 1.03.

[ricknismo]

do you have a boost controller or just the restricter removed?

[sewid]

Stock mate. I've not looked at many other 34's but I was under the impression they are running 1 bar from the factory +/- 0.1 for subtle changes due to mods/temperature/atmosphereic conditions...

[ricknismo]

Yeah I thought there might be a restricto in the standard solenoid line like my 32 and 33 had

34's dont have a restrictor in the line like the 32+33's ( they still have the lines marked on the hose though ) .

Stock boost on the 34's is .9-.95 bar with stock exhaust , they may spike a little higher .

[ricknismo]

Ok cool

Finally got new o2 sensors in...dear suckers..The others rattled and didn't register any volts.

Now it registers volts but only upto 1 v and the duty cycle still goes through the roof at high revs.

Don't the o2 sensors go to 5 volts?

<{POST_SNAPBACK}>

stock 02 sensors are narrow band and only show 0 to 1v. they shouldn't affect injector duty to that extreme i wouldnt imagine

phew
