im thinking of converting my turbos to non seq. i have a pettit unlimited ecu, can anyone tell me if this ecu will support this mod at 13psi? i was wanting to know since both turbos will be kicking in at the same time, the power curve will start lower
now and i dont know if this ecu will give me the fuel support i will need.

thanks

 

Power curve will start way later ns but pettit ecu will be fine, I ran this for awhile on Pettit ecu. Fuel system needs to be in top shape tho.

 

thanks for the input. my fuel system should be good i just put all new 850s and 550s in and i have a supra tt pump. how much boost were you running on this setup?

 

13 psi should be considered the safe limit on pump fuel....don't know why you think the power curve will start sooner, completely the opposite

short answer: yes, it will work

 

yes the power curve will start later since the 1st turbo is not boosting as early but what i was talking about is that the second turbo will be kicking in 1k to 1800k (from what ive read) sooner than it would be in seq form thus leaning the car out and producing more power earlier. with the ecu not expecting the second turbo until 4500k i didnt know if it would supply enough fuel for them both at that low of an rpm.

 

If you have the stock cat, you will only make more power than seq from about 4000 to 4500 rpm. A lot of people have run non-seq 12-13 psi just fine on the Pettit/M2 ecu.

 

no i dont have any cats, ported motor, all bolt ons
thanks alot for all the input
