det3 2jzge-t set up

[drew2322]

looking for any help on the set up and even a base map for my 1993 lexus sc300 2jzge na-t. I believe its wired correctly it connects and the car did start but soon shut off it was running too rich. any help would be awesome.

Is the DET3 coming on? There's a RED LED right by the vacuum line. Make sure you have a good vacuum source.

What injectors are you running? Is the KMV sensor still in place?

[drew2322]

Yes the tuner is installed correctly I believe I got the car to start and then it flooded its self. The maf is still in and I'm running 550cc injectors. I'm just not sure on ho to set the softer on the computer up and also a little help on the wiring would be good to so I know it's hooked up right.

Pin 27B should be your crank sensor. So you'll have to split that.

Also I attached what your settings *SHOULD* be

[drew2322]

thanks that's a big help. does rpm or throttle need to be hooked up. also if you could help with the analog settings and also the scals config and table setup this type of software is new to me I had a safc in the car before this. does the analog wire or the digital wire from my wideband get wired into the det3.

[ihiryu]

No, both of those gets left out.

Remember, since you're using a KMV sensor, you're gonna want to add a pull up.

So pin 3 and 10 of the DET3 goes to the Sensor.

Then pin 7 of the DET3 goes to the stock ECU.

[drew2322]

ok ya I did that. on the set up what do I use for the modify and load and corrections.

[ihiryu]

Most likely these settings.

[drew2322]

ok I have it set up that way but can not get it to start. it will crank and some time fire a little but never runs and stays running.

[drew2322]

where does the pin27b get wired into the det

[drew2322]

got the car running but the det is seeing double the rpm then the car is showing.

[ihiryu]

So you got the Crank sensor hooked up?

Change your ignition settings

Num signals per 720, try changing the number down to 3 and try it.

[drew2322]

I changed it but went higher and that fixed it.

[ihiryu]

Good deal. Did you have to touch any of your frequency settings?

[drew2322]

No something I think isn't right because sitting there idling it'll be at 14.4 on my wideband and then it'll lean out to 16 and then go back.

[ihiryu]

disconnect your o2 sensors.

[drew2322]

they are unplugged.

[ihiryu]

Sounds like either your fuel map isn't setup, or you've got a vacuum leak.

[drew2322]

I'm trying to set up the map and am not able to pull enough fuel the det is maxed out. And the car is still running rich. Is there a way to change so it takes more fuel with each step.

[ihiryu]

You set up the Frequency settings yet?

Also, you should be able to pull a lot of fuel, I think the DET can pull up to -127 or something like that.
