I have a 2 bar for my boost gauge gonna tap into the signal from that....the factory was so easy to tap into..lol shoulda read the instructions a little better lol

 

I know its easy, I just avoid tapping into the factory harness as much as possible. Really the only thing I have touched in the factory harness is rewiring my injector plugs.

 

I shoulda done the same...oh well

 

Hmm that may be correct. I had 18* base on my last tune in the high oct table, and actually used another COS3 table to pull timing.


Is meth really supposed to make a noticeable difference in IAT's with the TVS? I know the maggie guys typically did it for fuel.

 

I just want to make sure where I add timing there is no chance ill hit that area without the meth spraying.

 

I stole this pic from Blue Collar Performance's site. This is what meth does to the coating on your rotors when you spray it through the blower. No thanks.

Still want to inject water/meth PRE THROTTLE BODY on a roots/screw blower? Look at the coating blasted right off these Eaton TVS rotors!"

 

I just logged actual afr vs commanded via wideband input. And removed fuel where it told me to. Then anywhere over "turn on" for the meth I added timing a little at a time. Also in your iat timing tables ramp up the amount it pulls. That way if the meth stops it will pull loads of timing. Tuning for meth with the turbo was kinda tuff because boost comes in at all kinds of ranges.
