Boost Solenoid
Basically you need (2) T's -- one on the inlet side (one to solenoid and one to MBC) and then one T on the WG side (from solenoid and MBC)


I currently don't have an EGT probe, but will get one in a bit. I would like to run the car at ~28 psi (peak) on either 100% denatured Alk or 75% Meth / 25% h2o (still contemplating). That said, I think the ZT2 could act as a failsafe monitoring AFRs and Boost. So now my question to folks running similar setups:

(1) What alarms have you setup ?
(2) Do you think a basic if Boost > 18 psi and AFR > 12 would suffice ? (I thought about adding TPS in the mix, but thought it would be redundant.)

Thoughts?

Thanks again TTP!

plus, for me, meth is sooo much cheaper. i get it for $2.87/gal

i did my ZT-2 settings for >22psi, >95% TPS, >12.0 afr. the alarm sometimes goes off in first or second gear pulls (hits 12.1-12.2) when it was tunned for 11.5 afr on 3rd gear.

i suggest that you wire in only the alarm at first, to see how often it goes off.
