I have installed my HFS-6 and am currently trying to figure out how to wire it for alt map as a Failsafe. The manual does tell you which wire, pink one, but does not say where in the Evo 9 ECU you wire that up to. Any help would be appreciated.

Thanks

 

On the evo9. it is pin 64 for tephra alt-map.

 

I posted on both forums and you answered on both. Thanks again Richard.

 

I have just added Tephra altmap for evo 8, 9 and X for HFS-6 on the following link*:
(*may need to register first)

This is kind of a n00b question but to make Tephra Alt Map work, do i need to buy anything or is it all coded in the ECU?

 

you just need to be running one of my ROM's...

so your tuner needs to kinda know what todo..

i dont charge, but donations are appreciated

 

So question about this.....

So pin 64 is blank on the ecu... Do I need to add a pin in the ecu, add the wire, and then the tuner knows what to do?

 

it shouldn't be blank

make sure your looking at the right connector and the right way around

 

I downloaded a EVO ecu pinout diagram just to see and even it shows #64 as empty

Yes, you need to add a pin. I had bought a map switch kit from Buschur a while back for my old meth kit and then wound up going with the Aquamist kit. Since the map switching is built in to this kit I just needed the pin from the map switch assembly.

 

oh..

do you mean PIN on the ECU or PIN on the wiring harness?

 

Yes on a IX you have to add a pin and do some easy electronics to have less than 5V on the input when running on Alt map. If you do not feel confident with wiring and/or ROM tuning, go with someone who knows about both.
