This may sound like a stupid question (Yes - I've search but couldn't find the answer). I'm planning on supercharging my AP1 soon and running a stock ecu. I know that you should get it dynoed to ensure the afr is good. But if it's not good, can a tuner adjust my fuel and timing map?

TIA

 

no, not on a simply stock ecu.
end story, search more

 

stock ECU doesnt know what boost is... so KABOOM!

 

but stock ecu walbro + fmu + black box + 5-7psi = tunable <this a word?> s2k.

though i would never do it, it can be done. search for user moddiction he just finnaly got his working right.

 

if you buy a comptech kit, it comes with everything necessary to run with only your stock ecu and no tuning is required.

you can go to the dyno to see what your car makes though.

 

Thanks. That was the answer I was looking for.

 

u can tune it though if you have an adjustable FMU. some have a screw on them that you can turn to increase fuel pressure in boost.

 

And then my belt snapped lol.

 

^was it a SOS or Vortech or CT kit? i didnt see the thread.

 

^If that was to me I have a Vortech kit.

OP just get a wideband gauge. Don't need to go on the dyno or anything. A wideband will show you your afr and can continue to monitor them.
