hi looking for the recomended place to put the nozzle when running it with the stg 3 pcm? i have been injecting it aftrer the mass and having no problems... but since the ecm controls it now and i dont have my install inst any more... also does any one have a pic of the pin locations needed to be tapped into the ecm...

 

The install instructions are at http://www.crateenginedepot.com/pdfs/s3ins.pdf. I believe you can put the NO2 nozzle just before the SC or just after the SC. In theory I would think that having it after the SC and spraying into the intake would be most beneficial.

 

After Only

 

so basically like the nos instruction say 6-12in from throttle body... thats how its been prob 5in away

 

Sorry my previous post was so short, my boss was coming dangerously close to my computer. The ONLY way to inject the N2o is after the mass air flow sensor. Spraying before instantly freezes the sensor and that in turn throws the fuel/air mix off.

People have had threads before about which is better, to spray pre-blower or post blower. You can really do either its just a matter of which system you wish to use. A Pre-blower set-up is the run of the mill single N2o nozzle that just lets the system mix however it wants in the intake manifold. There is no control over which cylinder gets more or less of the mix because its sprayed so far ahead of the cylinders. The other kind of system is call a fogger system, every pro N2o motor runs a fogger system. In a fogger system each cylinder gets its own dedicated nozzle, this ensures that each cylinder is getting its proper amount of the N2o/fuel mix. A fogger on one of our cars would have to be custom made and its not a simple task.

 

yes.

 

if you're running a standalone and the computer is setup without extra injectors, you can program it in.

since you're asking the question in the first place, i expect you don't have a standalone
