    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)

    Manual cars for sure easier.. trans Tq request doesn?t matter.. but nitrous setups I?ve done 2 ways.. increase DD/peak Tq OR leave it alone and just add the nitrous on the same tune and leave Tq model stock (adjust timing on each, depending on octane)

    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 ?

    Any more info on this? im currently having this issue with a truck 150shot with the cylinder air mas decreases to lower .60's compare to NA which is usually in the .70's

    I have seen this before but it has never caused a lean issue. it does put you in a lower airmass part of the timing table so you have to be careful there.

    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?
