looking to spray my 2016 camaro headers robofab flex fuel gonna spray a 100shot already have jets set for e85...looking for tips on tuning it
will i have to adjust vt, driver demand tables? any advice is appriciated

Good luck.
There's no way of telling the engine where the extra power is coming from so when you exceed all the commanded torques, it's gonna shut the throttle on you.
I?ve done several nitrous cars... little tricky with these, but you can still keep the TB open (or Atleast I have on 200 shots)
Auto or manual?Quote:

But on gen 5s I like doing a separate nitrous tune and make the Tq model reflect the nitrous (make commanded Tq more accurate for trans/TB control and no need to have any timing retard box)
Yup that's what it comes down to. Gen 5 auto with a dedicated nitrous tune off bottle will drive and shift like shit. Having to write two different calibrations sucks in my opinion. Can't be like back in the days with Gen 3/4s where you just hit the switch to activate your timing box crack open the bottle while driving down the road in "mexico" and letting the motor rip.
Have you faced a problem were the injectors pulse width and cylinder air mass decrease (only when the nitrous is on) causing car to go lean ?Quote:

I was just curious, why can't you parallel into the Iat sensor wire, from the Nitrous solenoid with a resistor that sends it to approx 250* Iat and tune timing retard there? Do the new ecm's not like that?
Sooo I'm running a 75 shot and my trans is slipping after shifts. Do I increase the VTT at WOT 75 ft. lbs. to solve this? Or would this cause a throttle shut because its not measuring this torque?
