Aux output help

Post by jayc25xe »

hi all

Im needing some help with my outputs. I've been searching the forum for over an hour with no answers

So I'm running a dta s40pro on my c20let and have the outputs controlling the following-
Aux 2 - turbo valve
Aux 4 - fuel pumps (default)
Aux 5 - fan control
Aux 6 - tacho (default)

My issue is that I want to add a shift light which has now obviously been taken up by my fan control. I use the ecu to give signal to my aftermarket tacho so I cant alter Aux 6 so how do I get the ecu to control the shift light.

I could move my fan control to Aux 4 and use the original Aux 5 for the shift light but then how do i bring my fuel pumps on

Any help would be greatly appreciated

You've run out of outputs. You will either need to move something off the ECU, or upgrade to an S60.

Or lose the DTA fan control and use a standalone switch in the top hose - I do that to provide cooling after engine off. Damn sight cheaper than a DTA S60 upgrade LOL!

True, but the S60 is lots better and has logging.

I'd get the S60....but the fan switch is definitely cheaper lol

And a s/hand S60 is £550 - 650! So £150 - 250 against a £20 switch? ;)

If i was to upgrade to a s60 would I have to have a map done from fresh or can the map be transferred from my s40

Map will transfer from S40 just fine. But just check it all over any way.
