Im trying to get a 93 octane map and a c16 map on the stock ecu. What all do i need for my tuner to be able to do this?

 

Go look in the ECUflash forum. I believe some of Tephra's ECU patches allows this.

 

Well you're going to need quite a few things. You'll need to have Ecu controlled boost. This requires a JDM Map Sensor....same as USDM X MAP Sensor. You'll also need a Boost Control Solenoid like the GM 3-PORT. You'll need to Flash your rom with a couple of patches. First the Tephra v5.10 patch. Then you'll have to look up mrfred and check out his threads on ecu controlled boost and jdm map sensor mods.

 

It involves wiring a switch to your ECU. Look for the AltMap mods in the ECUflash forum.

 

You do not need a JDM/EvoX MAP or ECU boost control to do map switching....

 

If you have a laptop and a tactrix cable, you could carry around both maps and switch em when you need to.

 

sorry I was thinking on the fly. I'm in the middle of Alt Map switching with my meth kit. sorry to confuse.

 

uhhh i guess ill just let my tuner handle all this...sounds confusing to me

 

I offer alt map switching harness' that work with Tephra's v5.10 patch so if you go that route I have what you might need.
