I mean, can you use a GS430 ECU tu run a LS430 engine?

Can you run an GS430 ECU in an LS430 engine?

I removed the pin by mistake actually!

I removed the temp sensor (B/R wire) pin out of the 3A590's connector. Who knows where the pin goes in the 28 pins' connector? My pinout only shows tranny pins plus RL, WFSE, LCKI and MOPS.

Yes, all from same car.- If the key is not correct, or there is no key, it will continue blinking when on righ? like in the 1UZs??

Must be IMMO, I got the complete harness from the door car, its even connected with the harness. And don't start actually. Are IMMO boxes the same board with different part numbers? Thinking to try with another IMMO box.

I use a 12V LED with one contact to IMLD from the IMMO box and the other to ground. (it turns on when I power the led). Same thing that I test the IMLD output on a non IMMO box ecu. But does not bring signals

I have in hands a 1GR FE with external Immo box. I connected all wires that I assume are needed, but ECU did not even blink the security light. Is there something extra to connect to run the Immo Box? I have the original harness, Immo Box, ECU, etc. I leave the key apart to test the imld...

I got in my hands a 1UZ VVTi that looks the "newer" ones, that has the newer type of coils (like 3UZ, 1GR, etc) and the ecu in the engine bay with the harness leaving the engine at front. Does this ECU use the same pinout of previous ones? (3A590) I have doubts with +BM and Immo plugs...

Adding to previous message. Does this means the pump never starts before cranking? at "Start" for example?

And does it stops the fuel pump (relay´s coil actually) after some seconds when engine is not running and key in Start position ?

Thanks for reply. That FC pin grounds the relay coil too or power it?

Still does not ground the pump's relay. any idea why not? Thanks in advance

I am installing an 1UZ VVTi but have troubles with the fuel pump relay's control. I like to use the FPR function, where the ECU grounds the Fuel pump relay by to start/cut the fuel pump. (I skip MREL function) I wire the pin 4 in the 22 pins' connector to relay coil , but ECU is no...

Its a 80/40 ECU connected as: 56 - IGT2 57 - IGT1 58 - IGF1 59 - IGF2 Cant read codes already

In such case, IGF1 is in the slot of IGF2 and viceversa or tottally different location? I have one 1UZ first generartion that starts for one sec and stops. I builded the inginer and maf wiring as per diagrams and looks to be ok,

What production year for the Tundras was when starts using the VVTi 2 UZ? How can I recognize one or another?

In this LS400's ecu, if I feed the amplifier with B+ (efi relay powered) the light does not stop flashing, need BATT voltage. I just get into a 2000´s LS400 and the light goes off just puttin the key in.

No idea??????

I tried with and without grounding EOM with same results. I am still lost with the KSW. Watching some videos on the LS400 IMMO, I see the safety light flashes when door is open, and stops just when the key is inserted. But as per diagram, the antenna amplifier is feed by +B not BATT. So in...
