3.4 Supercharger with F/IC-6 TUNING

Is the process the same for the 1997 ECU and a Boomslang will work for 1997 too?

 

Process is the same, Ecu is different. You will need a different harness. Here a link to the harness you’ll need to run the fic-6

Plugged in the Boom Slang yesterday ran a vacuum line to the FIC

Truck started and died
Plugged in the bypass harness to the FIC , truck started and die.
Plugged the ECU back to stock, truck runs as normal

Am I missing something?

 

You need a different harness. Also why are you running different injectors? The stock ones are fine especially if you are running the 7th inj Kit. I’m running almost 10psi with no problems.

 

Different harness?

Please elaborate

No 7th

Incorrect.
3rd gens are able to flash and it's ~$750.

OVTune has still not figured out how to/ which later 1st gen ECUs are tunable, but the latest information is ONLY the Sep 2002-2004 5VZ with the iECTS, commonly incorrectly referred to as the "fly-by-wire" throttle.

 

All these trucks for whatever reason act differently and need a different solution.

I replaced my fuel pump and MAF with new OEM parts and this changed my fuel trims and fuel needs.

I’m running 10.4 pounds of boost 2” pulley and now only need the methonal spraying above 7 pounds of boost with the smallest nozzle while before I was spraying with a 3 nozzel and from 3.5 pounds up.

After replacing those two items the truck barely needs any fuel enrichment with the 2” pulley and zero ping issues.
So I don’t need a high flow fuel pump or larger injectors.

Ping issues, lean issues can be caused by
Carbon build up
Weak fuel pump
Fuel filter
Fuel regulator
02 sensor
Exhaust leak
Vacuum leak
Dirty injectors
Bad MAF

Etc

If I’ve learned one thing about these trucks in all the miles I’ve driven
is if there is one thing that’s out of sync it effects the bottom line of how the truck runs.

Watching your fuel trims is a good way to monitor your fuel health and ECU dance

 

Boomslang ran a diagnostic and discovered one of the pins was pushing it out and not connecting to the ECU

They corrected it and are sending it back to me

 

Thanks for that info, is tuning the same? I know the 02 sensor on the 2000 forward ECU gives more
info than the 1997 ECU specifically the 97 ECU doesn’t give an air fuel ratio from the O2 sensor.
I do have a stand alone one tho

 

The tuning is the same but the older Tacomas have a narrowband O2, the 2000-04 have a wideband.
Also the settings are set up a little differently on the FIC6 due to the different O2 readings.

 

Subbed,Researching... Starting to save for Boost as the next part of my build.
