FIT Wiring [ST205]

[felipeandrest205]

Hello friends, I have my DET3 wired to only use DET3 as piggyback, but I want to know what else do I need to use Fuel Implant mode, I mean if i need to connect injectors on the det3 or another sensor, and where should I connect those wires on the det3.

Greetings from Chile!

Any help?? I have the DET3 connected with the ignition and the map sensor, 12+ for power supply, earth and a wideband in a analog. What else should I connect to use the Fuel implant technology?
Any one can help me? Greetings!
Im using the det3 as piggyback and its.going.fine, just want to use FIT mode for the launch control and the boost controller

You can use launch control and boost control without rewiring it for FIT mode.

Well today read and ask a lot, so whats the benefits if i rewire to use FIT mode? (Add coolant temp sensor, air intake temps and injectors).

Also it says that need to connect injectors as power output, but practically the manual said that need to connect pairs of injectors on bank fire 1 and 2, how would be the sequence? Injectors 1-3 on bank fire 1 or 2-4 on bank 1?
Need to connect them in pairs, so just bridge them with a wire and connect it in the power output?

Still reading the manual and I answer myself but have other question, the manual says that in order to use the.boost.controller, i need to conect all the injectors in the first power output (pin20), working on full group (batch fire i think), so if i connect them in bank fire (using the 2 power outputs), I will not.be able to use the.boost controller?
Is that correct? How do you recommend me to connect the injectors to.be able to use the.boost controller?

you can wire the mac valve (boost controller) with the additional transistor so you can wire your injectors in pears. also the benefits of fit mode are much more than piggyback mode, fit mode works like a stand alone ecu but you have the oem ecu to control idle valve end other sensors "secondary staff"

[WHPZach]

FIT mode operates like a standalone fuel controller, which means the tuning process is far more involved and will take much more time. Unless you absolutely need it, don't bother with it.

I just want to raise the boost and then remap the overfuel, also try to use the launch control, I do not need the FIT mode?

Peggy back mode would be fine. dont go to hight the boost my friend recently blow his 3s caldina your any way is stronger

[felipeandrest205]

Dont worry mate, know the limit of the turbo and the engine, just going for 1.1bar at hight boost with metal headgasket and arp headbolts
Now I understand how to raise the boost... didnt know that PWM tables were to control the duty cycle, im just new on the progamming of the ecu, but learning safe and slow, thanks for all the help

[felipeandrest205]

Now im looking how to wire to raise the boost by the PWM tables

I have the T-VSV wire from the ECU in my hand, should I only t-splice it to Power out#2?

And power ground only goes to earth? I mean to the chasis, or to a earth supply from the ECU?

Can some one help me?

chassis ground
