Hi guys ,

I am currently installing my HFS-3 kit on my evo 9 and it is about 80% completed .

I used the wiring diagram that Richard sent me , and I want to run a dual map setup with Tephra as a failsafe .

My problem is with the white wire use for the alt-map . Diagrams says to use the ECU pin 64 , but there is nothing at all in this pin .

Buying new pins and get that wire in there is the only way to go to make this setup work ???

Fortunately , SpoolinUp have new pins in stock , but it seems a PITA to get a pin in the oem harness ....

Thanks !

 

Okay , I ordered some pins from SpoolinUp and i got this thing done in a few minutes . It was pretty easy but still a bit stressfull when working one the ECU wiring and tiny parts such as ecu pins .

Now , I just have to wait to get tune to see if it is working .

 

quick question - sorry for bumping a 2 year thread - was the OP successful in getting the alt map to work using the plug in to pin 64 of the ecu?

 

yes sir . Everything was working like a charm . When the failsafe gauge was ON , i was on alt map . When i turned it off , it switched to main map .
