hi im new to the whole det3 how should i wire it to my ecu and will i need to use a hks fcd for fuel cut dose any one have any diagram or any info any littile bit will help thank you

Any one

You'll need to intercept the MAF wire (to an analog input on the DET3, then analog output to your stock ecu) and intercept the crankshaft position sensor (NE on toyota wiring diagrams). I don't have a diagram handy, but might be able to put one together this week.

You will not need an FCD, you can clamp the output voltage with the DET3.

Please if you can put a diagram together i would so appreciate it its a jzs161 aristo 2jzgte vvti im really confused because the car has a factory map and maf so please help if you can thank you

The MAF sensor is the important one. Cut that wire. Wire from MAF to analog input, wire from analog output to the stock ecu.

Thank you I found this motor quite easy to tune although the final was not done by me.

I am looking forward to a ride with the VVTI working

the vvti have the 30-2 trigger weel the ignition mode is retard-advance miltitooth signal the ignition input type is vr sensor adaptive thredhold maximum rpm 7000 num signal per 720 is 24

setup table ----- fuel table analog #1----- analog #1-------disable------disable----------------ignition table-------analog#1-------analog#3--------------analog#4--------------------pwm table #!--analog#1---analog#3 analog#4 pwm table #2 is the same
